We would have a much harder time following the phases<br /> <br /> Kim Blackseth is the recommended person (he did the CASp inspectiion for Omni (where sudo roomis)) was about 4k for whole inspection.<br /> This process will be expidited by having archatectural floor plans. Also make sure to have upgrade drawings ready as well<br /> <br /> it does not need to be notoarised or certified floor plans, they just need to be accurate to scale, for doors and the like.<br /> <br /> David is getting a quote for a inclined stair lift vs a verticle elevator <br /> <br /> it would be hard to install a full ada compliant stairlift or elevator.<br /> <br /> We need to find the proper place to put them.<br /> <br /> Start clearing the different bars for ADA, first floor is most importaint, then worry about the second floor.<br /> <br /> Wide enough doors, ADA bathroom, make sure anything that could be hosted upstairs can be hosted downstairs if need be are the main first steps.<br /> <br /> ''I talked to David Keenan on 29 July 2020. He recommended Kim Blackseth as CASp inspector, and had a lot of useful information and suggestions for how to move forward.

Also make sure to have upgrade drawings ready as well<br /> <br /> it does not need to be notoarised or certified floor plans, they just need to be accurate to scale, for doors and the like.<br /> <br /> David is getting a quote for a inclined stair lift vs a verticle elevator <br /> <br /> it would be hard to install a full ada compliant stairlift or elevator.<br /> <br /> come join us on friday<br /> <br /> start clearing the differetn bars for ADA, first floor is most importaint, then worry about the second floor<br /> <br /> wide enough doors, ADA bathroom, make sure anything that could be hosted upstairs can be hosted downstairs if need be.<br /> <br /> LXPK - sound resonable, we can discuss more on friday<br /> <br /> <br /> <br /> === Discussion Item 2===<br /> Pyconaut: fundraising guild meeting time (planning) - previous meeting was the hour before Tuesday general meeting (so 7pm), but we might want to change that? some specific ppl we want to have involved (e.g. Tyler), so need to find time that works for them<br /> <br /> Pyconaut was one of the ppl involved in the previous fundraising group, so want to join to share knowledge from past efforts, is free most evenings (except tuesdays and thusdays and the friday ADA guild time)<br /> <br /> lxpk will attend whenever they can<br /> <br /> Pyconaut will make a Google form for ppl to sign up the fundraising effort; anyone is free to join, it is pretty involved, you *will* have work to do outside of the mtgs, will hold ppl accountable<br /> <br /> During the first mtg, pyconaut will try to share knowledge from past meetings, others should share what they've learned in or out of NB<br /> <br /> Aaron may be interested in joining?<br /> <br /> Pyconaut will send out something in the next couple of days re: meeting<br /> <br /> Questions? (crickets)<br /> <br /> === Discussion Item 3===<br /> <br /> Both lxpk and pyconaut are working on 3D models; will probably need to rework once X has done accurate plan drawings; the plans we have so far are not all that accurate, but accurate enough to come up w/ designs for the new space<br /> <br /> pyconaut's model is mostly the building, incl. ADA features; didn't have exact metrics, so over-estimated some things - needs input from others<br /> <br /> lxpk suggests Tuesday pre-meeting, 3D modeling session should start no later than 7pm, pyconaut might start closer to 6pm since he likes to model for long periods - several ppl can simul-stream, so can watch multiple ppl working on their models at once<br /> <br /> will also have models for ppl to dl and mod, will link in Slack / Discuss / Discord - lxpk has already shared their model<br /> <br /> Time for a new SimBridge (!) - maybe this should live under VR Guild - lxpk's new model will also include the old one, since their old model already incl. the 272 Capp building as part of the external context<br /> <br /> discuss link to discussion (links to project files will be shared soon)<br /> https://discuss.noisebridge.info/t/simbridge-simulated-noisebridge/1984<br /> <br /> Mark: We should look into version control solution so we can all collaborate and share ideas in the new model, asynchronously. Different versions of the model should exist, but all accessible via a singular repository of some sort. https://blender.stackexchange.com/questions/7378/diff-and-version-manage-blender-work<br /> <br /> = End of Meeting =<br /> <br /> 11 ppl in attendance by the end of the meeting at 9:09<br /> <br /> [[Category:Meeting Notes]]</div>

HCoV-19 or coronavirus) particles in aerosols (from breathing, coughing, speaking, etc.) and on environmental surfaces (from contaminated hands or aerosols settling) provide evidence that the viral particles remain viable for widely differing periods depending on the surface, ranging from several hours (for aerosols) to multiple days (up to 7 days on smooth surfaces).<br /> <br /> According to one study, ''&quot;SARS-CoV-2 was stable on plastic, stainless steel, glass, ceramics, wood, latex gloves, and surgical mask, and remained viable for seven days on these seven surfaces. As is shown in Figure 1A, the virus titer declined slowly on these seven surfaces. For example, its TCID50/ml [50% infectious tissue culture dose per millimeter] decreased from 105.83 at time zero to 10^2.06 at day 7 on plastic, which was about a 3.8 log10 reduction from the original inoculum.&quot;'' (1)<br /> <br /> Another study on the stability of SARS-CoV-2 in aerosols and on various surfaces found that ''&quot;HCoV-19 was most stable on plastic and stainless steel and viable virus could be detected up to 72 hours post application (Figure 1B), though by then the virus titer was greatly reduced (polypropylene from 10^3.7 to 10^0.6 TCID50/mL after 72 hours, stainless steel from 10^3.7 to 10^0.6 104 TCID50/mL after 48 hours, mean across three replicates).&quot;''<br /> <br /> The same study also found that ''&quot;HCoV-19 remained viable in aerosols throughout the duration of our experiment (180 minutes) with a reduction in infectious titer 3 hours post-aerosolization from 10^3.5 to 10^2.7 CID50/L (mean across three replicates). This reduction in viable virus titer is relatively similar to the reduction observed in aerosols containing SARS-CoV-1, from 10^4.3 to 10^3.5 TCID50/mL (mean across three replicates) (Figure 1A).&quot;'' (2)<br /> <br /> <br /> The CDC states that:<br /> <br /> '''&quot;The virus is thought to spread mainly from person-to-person.'''<br /> * Between people who are in close contact with one another (within about 6 feet).<br /> * Through respiratory droplets produced when an infected person coughs, sneezes, or talks.<br /> * These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.<br /> * COVID-19 may be spread by people who are not showing symptoms.&quot;<br /> <br /> And further that:<br /> <br /> '''&quot;The virus may be spread in other ways.'''<br /> It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes. This is not thought to be the main way the virus spreads, but we are still learning more about how this virus spreads.&quot; (3)<br /> <br /> <br /> Based on this information, &quot;decontamination by time&quot; would require the space to be kept entirely closed for an absolute minimum of 72 hours, with at a week being optimal to eliminate the risk of surface transmission. Taking this precaution as part of the effort to prepare the space for moving would be strongly recommended.<br /> <br /> <br /> '''(1)''' '''''Stability of SARS-CoV-2 on environmental surfaces and in human excreta'''''. 2020.

<p>Rikke: </p> <hr /> <div>=Mushroom cultivation=<br /> <br /> Welcome to the Tastebridge mushroom cultivation wiki. This page is meant as a combined documentation of the Noisebridge mushroom project, and a simple beginner's guide to doing the same at home. The page is sorted by species (so far only one) and sub-divided by substrate for those species that have been / are growing on more than one different substrate.<br /> <br /> <br /> ==Oyster mushrooms==<br /> <br /> ===Sawdust substrate===<br /> <br /> '''Ingredients'''<br /> <br /> * sawdust, 50/50 oak/alder<br /> * gypsum<br /> * water added to 65% wet weight<br /> * hydrogen peroxide 3%<br /> * Spawn Mate SEII<br /> * mushroom spawn<br /> * spawn bags<br /> <br /> The initial moisture content of the substrate should be measured before start; this can be done by weighing out a small sample of sawdust, drying it in a microwave oven, weighing it again and calculating % moisture like so:<br /> <br /> Wtotal - Wdry = Wwater<br /> (100 / Wtotal) * Wwater = % moisture<br /> <br /> The final moisture content should be around 60% of the total weight, so adding about 65% water will result in appropriate levels after evaporation and addition of gypsum and Spawn Mate. The water should be boiling when it is poured on the sawdust, mixed in as quickly and thoroughly as possible, and the mix then left to cool.<br /> <br /> Once the wet sawdust has cooled to &lt;50°C / 120°F, add 3 % by wet weight of a 3% hydrogen peroxide solution, after first, making sure that the hydrogen peroxide does not react with enzymes (peroxisomes) in the saw dust, as this will spoil the disinfective properties. This can be done by mixing a bit of the sawdust with hydrogen peroxide. If there is no fizzing, simply add gypsum and boiling water. If it fizzes, the sawdust will need to be boiled for about 30 minutes to cease enzymatic activity before the peroxide can be added. Also, do not be tempted to add the peroxide to the water before boiling, as the decomposition rate of H2O2 increases massively with temperature.<br /> <br /> Once peroxide has been mixed well into the sawdust/gypsum, the substrate needs to be further cooled to room temperature, then supplemented with 7-32% per dry weight Spawn Mate SEII:<br /> <br /> (Wdry / 100) * target% = Wsmii<br /> <br /> The last step is the inoculation; a relatively high spawning rate is recommended with the peroxide treatment, as mycelial growth will be slowed down somewhat by the peroxide, and by the microbial competition that the substrate has not been sterilized of commercial spawn grown on millet (from Amycel, Inc.), then transferred in 12-13 lbs. portions to XL spawn bags. The mixing can be done in the spawn bags or in a large plastic tote, and the final mix is then put in the spawn bags, which are sealed, preferably with an impact sealer.<br /> <br /> Original estimates of colonization rates were about 4 weeks, but these turned out to be overly pessimistic. Our blocks were inoculated on two separate occasions, 21 and 27 July 2011, and the first blocks were fully colonized by July 29th and fruiting heavily by 8 Aug (see photo). Once the blocks are completely colonized (see picture), the fruiting can be initiated either by taking them out of the bags, or by making a bunch of X-slits in the bags spaced about 2&quot; / 10 cm apart and placed in a climate-controlled fruiting chamber. The chamber can be constructed by covering a wire shelf rack with thick plastic, adding a small fan and a humidifier (preferably on a timer so it only runs during day time) - temperatures should be within 15-25°C / 60-75°F, and relative air humidity optimally between 90% and 93%.<br /> <br /> <br /> ===Coffee ground substrate===<br /> <br /> '''Ingredients'''<br /> <br /> * coffee grounds from a coffee shop<br /> * coarse vermiculite (optional)<br /> * Spawn Mate SEII (optional)<br /> * mushroom spawn<br /> * spawn bags<br /> <br /> In an attempt to bring mushroom cultivation costs down as low as possible, we wanted to try out coffee grounds as a fruiting substrate for oyster mushrooms, as grounds are (generally) free and plentiful, and easy to come by in urban areas with lots of coffee shops. The initial plan was to use the peroxide technique again, but the peroxide reacted fairly strongly with the coffee, so instead, we tried three different options: 1) pressure cooking + Spawn Mate supplementation, 2) no cooking + Spawn Mate supplementation, and 3) no cooking + no supplementation.<br /> <br /> Start out by measuring the moisture content of the coffee grounds as described for the sawdust above. Then add water, and optionally vermiculite for a looser texture.</div>

The page is sorted by species (so far only one) and sub-divided by substrate for those species that have been / are growing on more than one different substrate.<br /> <br /> <br /> ==Oyster mushrooms==<br /> <br /> ===Sawdust substrate===<br /> <br /> Ingredients<br /> * 80 pounds of sawdust, 50/50 oak/alder<br /> * 1 pound of gypsum<br /> * water added to 65% wet weight<br /> * Hydrogen peroxide 3%<br /> * Spawn Mate SEII<br /> * Mushroom spawn<br /> <br /> The initial moisture content of the substrate should be measured before start; this can be done by weighing out a small sample of sawdust, drying it in a microwave oven, weighing it again and calculating % moisture like so:<br /> <br /> Wtotal - Wdry = Wwater<br /> <br /> (100 / Wtotal) * Wwater = % moisture<br /> <br /> The final moisture content should be around 60% of the total weight, so adding about 65% water will result in appropriate levels after evaporation and addition of gypsum and Spawn Mate. The water should be boiling when it is poured on the sawdust, mixed in as quickly and thoroughly as possible, and the mix then left to cool to room temperature.<br /> <br /> treated with 3% hydrogen peroxide to a total of 3% of wet weight<br /> <br /> supplemented with Spawn Mate SEII at 7-32% of dry weight <br /> <br /> (Wdry / 100) * target% = Wsmii <br /> <br /> inoculated with 20 pounds of commercial spawn grown on millet (from Amycel, Inc.), then transferred in 12-13 lbs. portions to XL spawn bags <br /> <br /> <br /> First, make sure that the hydrogen peroxide does not react with enzymes (peroxisomes) in the saw dust, as this will spoil the disinfective properties. This can be done by mixing a bit of the sawdust with hydrogen peroxide. If there is no fizzing, simply add gypsum and boiling water. If it fizzes, the sawdust will need to be boiled for about 30 minutes to cease enzymatic activity before the peroxide can be added. Do not be tempted to add the peroxide to the water before boiling, as the decomposition rate of H2O2 increases massively with temperature.<br /> <br /> After cooling the wet sawdust to &lt;50°C / 120°F, the peroxide can be added. Once peroxide has been mixed well into the sawdust/gypsum, the substrate needs to further cool to room temperature, then supplemented with 7-32% per dry weight Spawn Mate SEII. The mixing can be done in the spawn bags or in a large plastic tote, and the final mix is then put in the spawn bags, which are sealed, preferably with an impact sealer. <br /> <br /> Original estimates of colonization rates were about 4 weeks, but these turned out to be overly pessimistic. Our blocks were inoculated on two separate occasions, 21 and 27 July 2011, and the first blocks were fully colonized by July 29th and fruiting heavily by 8 Aug (see photo). Once the blocks are completely colonized (see picture), the fruiting can be initiated either by taking them out of the bags, or by making a bunch of X-slits in the bags spaced about 2&quot; / 10 cm apart and placed in a climate-controlled fruiting chamber. The chamber can be constructed by covering a wire shelf rack with thick plastic, adding a small fan and a humidifier (preferably on a timer so it only runs during day time) - temperatures should be within 15-25°C / 60-75°F, and relative air humidity optimally between 90% and 93%.<br /> <br /> ===Coffee ground substrate===</div>

<p>Rikke: </p> <hr /> <div>[[File:Tastebridge_logo_lm09102010.gif|top|center]]<br /> <br /> <br /> Tastebridge<br /> <br /> <br /> Tastebridge is a food hacking group originating in the http://noisebridge.net Noisebridge hacker community in San Francisco, California, USA. We focus on traditional high quality food preparation combined with today's scientific knowledge and current technology. One of our major goals is to bring the slow food movement to the home and make it more easy and reliable, as the Governator says “sexy”. Our projects encompass artisan food and beverage culturing such as kombucha and soda pop brewing, yogurt making and of course preparation of various dishes from all different parts of the world. One of our major focuses is design and collection of equipment which would help with above mentioned activities. We are interested in building free open source incubators, dehydrators etc. We are looking forward to promote our activities in the communities in different part of the world stimulating their development in the direction of local sustainability.<br /> <br /> Sincerely Yours,<br /> <br /> for Tastebridge,<br /> <br /> Frantisek Algoldor Apfelbeck <br /> <br /> <br /> For more details, please sign for our discussion list<br /> <br /> [https://www.noisebridge.net/mailman/listinfo/tastebridge Tastebridge mailing list groups]<br /> <br /> <br /> <br /> '''Activities within Tastebridge'''<br /> <br /> <br /> [[Promotional Events and Parties]]<br /> <br /> [[Cultured Drinks Brewing Program]]<br /> <br /> [[Cooking Classes]]<br /> <br /> [[Recipes and Manuals]]<br /> <br /> [[Logs]]<br /> <br /> [[https://www.noisebridge.net/wiki/Noisebridge_Distilled Noisebridge Distilled]] <br /> <br /> [[Direct Disaster Response to Japan]]<br /> <br /> [[Food Hacking Base CCC Summer Camp 2011]]<br /> <br /> [[Hack-mobile]] status Hiatus<br /> <br /> [[https://www.noisebridge.net/wiki/NoisebridgedelChiapas Noisebridge del Chiapas]] status Hiatus<br /> <br /> [[Mushroom cultivation]]<br /> <br /> <br /> '''Temporary hosting'''<br /> <br /> <br /> [[091 Brew Masters]]<br /> <br /> <br /> '''Past Parties'''<br /> <br /> [[https://www.noisebridge.net/wiki/Thanksgiving_Party Thanksgiving Party]]<br /> <br /> [[Category: Sustenance]]</div>

<p>Rikke: </p> <hr /> <div>=Introduction to pH=<br /> A pH measurement of a medium is a measure of how acidic or how basic it is. Lemon juice or vinegar for example are acidic, whereas bleach or sodium bicarbonate are basic (the opposite of acidic). <br /> <br /> pH can be imagined as a measure of the presence of hydrogen ions or H+ in the medium or the ability of the medium to produce H+ ions. An acid produces H+ ions whereas a base absorbs H+ ions. <br /> <br /> In more technical terms pH is defined as a negative decimal logarithm of the hydrogen ion activity in a solution. Using this definition, a pH value of 7 corresponds to a neutral solution, neither acid nor basic. A pH value &lt; 7 corresponds to an acidic medium, and a pH value &gt; 7 corresponds to a basic solution. Anyways, the reason you care about all this is that biological systems are very sensitive the pH of their environment. Whether or not fish survive in a lake or whether your fermentation goes well for your latest beer batch depends on the pH. So it it is kinda important. You can read a lot more about pH by following some of the links provided below or by browsing the Internet.<br /> <br /> =Building a pH probe=<br /> A pH probe is device designed to measure the pH of a medium. The entire pH assembly consists of 2 parts. These are namely the sensor or probe part, and the meter. A nice description on how to build your own meter is provided in another part of this wiki.<br /> <br /> You could probably run out and buy a pH probe if you wanted. The costs varies quite a bit depending on what you are looking for, but where would the fun be in that? Here we show you how, with a few simple household items, you could build you own pH probe at home using readily available materials.<br /> ==Glass electrode==<br /> The key to pH measurement is the use of some kind of barrier that allows H+ ions to flow across it. It turns out really thin glass does this very well. recently, there have been advances using fancy membrane materials to make pH probes as well, but we'll stick to the glass pH probe here.<br /> [[File:IMAG0100.jpg|200px|thumb|right|Good old X-Mas Ornaments]]<br /> I can across a paper where they described how to make a home made pH probe using a Christmas glass ornament and some simple materials. This is a great way to make a pH probe on the cheap at home. <br /> <br /> ===What you need===<br /> So what you'll need to make this thing are:<br /> <br /> 1. A Christmas glass bulb, the smaller, the better<br /> <br /> 2. Some household bleach<br /> <br /> 3. Some plastic tubing, plastic straw or similar<br /> <br /> 4. Some epoxy glue or even better, aquarium glue<br /> <br /> 5. Some silver wire. I got some from my neighborhood hobby store<br /> <br /> 6. Potassium chloride, this is available as low sodium salt or as vitamin capsules. Very easy to find.<br /> <br /> 7. Water<br /> <br /> In addition to the glass pH probe, you'll need a reference probe. The pH probe by itself is only a half cell. In order to complete the circuit, you'll need the other half of the cell. The trick with the reference electrode is that it must provide a steady voltage, so that the pH can be measured. Otherwise your measurements will jump all over the place and you will never get a result. <br /> <br /> To make the reference electrode, you will need:<br /> <br /> 1. A piece of plastic tubing or straw<br /> <br /> 2. Some silver wire (see above)<br /> <br /> 3. Potassium chloride (see above)<br /> <br /> 4. Water<br /> <br /> 5. Agar Agar - from the supermarket<br /> <br /> ===How to build it===<br /> [[File:IMAG0103.jpg|200px|thumb|right|Naked Bulb]]<br /> 1. To make the glass electrode, you first need to remove all the coating and junk that they use to decorate it. This is accomplished boiling it in bleach for a couple of hours. You'll notice the the covering peel off. Let it cool, and carefully take it out and scrape off the paint. If it is still difficult to remove, dunk it back in the bleach in and boil it some more. Eventually it will all come off. You should have a clear glass bulb. It must then be conditioned. I did this by soaking it in a dilute vinegar solution for a couple of hours, followed by dipping in dilute bleach solution for another couple of hours, and then rinsing it in water. When not in use, the glass bulb must be kept wet at all times. Just leave it in jar of water.<br /> <br /> 2. Now to make the rest of the probe I used a plastic pipette, but a piece of plastic tubing, glass tubing or plastic straw of the right size should work fine. Cut the tubing to the desired length and glue it to the open end of the glass bulb. This is basically the probe housing.<br /> <br /> 3. To make the silver chloride wire, simply dunk some silver wire into bleach for a few hours. I did this overnight. You'll notice the silver wire turn brownish. This is the coating of silver chloride (AgCl) that develops on the surface of the wire. <br /> <br /> 4. Insert the silver chloride wire into the probe, and fill it with saturated potassium chloride solution (KCl). To make a saturated solution, keep dissolving potassium chloride in water until no more disolves and you have some KCl crystals hanging around.<br /> [[File:IMG286.jpg|200px|thumb|left|Voila!]] <br /> 5. Thats pretty much it! you have a pH probe. I capped mine off with a rubber stopper to keep liquid in. And you should have something that looks like this:<br /> <br /> <br /> The reference electrode. Making the reference electrode was much harder. Not because it was hard to make, but because there is very little written about it. A couple of nice posts on the web were helpful in helping me hack one together.<br /> <br /> 1. The big trick with the reference probe is the fact that it is also in contact with the medium of interest via a porous membrane of some sort that is not glass. Glass is used to measure pH. the reference electrode just provides a steady voltage for the measurement. Most commercial electrodes available use vycor tubing. This stuff is a little expensive and not the easiest thing to come by. <br /> <br /> 2. A cleaver alternative was to make a membrane out of agar agar and some potassium chloride. <br /> <br /> To prepare this, dissolve up some agar agar in KCl solution. Cut a piece of plastic tubing, seal off one end and dip in the hot solution. Let cool and set. Then dip a small piece of cotton in silver chloride or salt solution, and insert it into the tube. Top off the rest of the tube with agar solution. <br /> <br /> 3. Similarly to the pH probe, insert a piece of silver chloride wire into the the length of the tube but above the cotton piece. Let it sit for a while and the agar should solidify. You then have a functional reference electrode. It should look something like the complete probe shown in the image on the right. [[File:IMAG0144.jpg|200px|thumb|right|Complete pH probe]] <br /> <br /> ===Things to keep in mind===<br /> 1. The agar in the reference elctrode may not withstand harsh pH environments (very acid or very basic).<br /> <br /> 2. The agar melts at ~80C<br /> <br /> 3. Be careful with the type of tubing used to make these probes. Some plastics such as PVC may not survive harsh pH conditions.<br /> <br /> ===Interfacing and measuring===<br /> <br /> All you need now is to connect the two silver wires to a pH meter and you are good to go. <br /> <br /> Do not be alarmed if at first you get really weird results.

<p>Rikke: /* pH amplifier circuit */</p> <hr /> <div>=Introduction to pH=<br /> A pH measurement of a medium is a measure of how acidic or how basic it is. Lemon juice or vinegar for example are acidic, whereas bleach or sodium bicarbonate are basic (the opposite of acidic). <br /> <br /> pH can be imagined as a measure of the presence of hydrogen ions or H+ in the medium or the ability of the medium to produce H+ ions. An acid produces H+ ions whereas a base absorbs H+ ions. <br /> <br /> In more technical terms pH is defined as a negative decimal logarithm of the hydrogen ion activity in a solution. Using this definition, a pH value of 7 corresponds to a neutral solution, neither acid nor basic. A pH value &lt; 7 corresponds to an acidic medium, and a pH value &gt; 7 corresponds to a basic solution. Anyways, the reason you care about all this is that biological systems are very sensitive the pH of their environment. Whether or not fish survive in a lake or whether your fermentation goes well for your latest beer batch depends on the pH. So it it is kinda important.

<p>Rikke: /* Digital thermometer */</p> <hr /> <div>=Introduction to temperature measurements=<br /> <br /> We are all familiar with the classic simple analog thermometer - the one with the resevoir of mercury or alcohol at the bottom. Unfortunately it is not very easy to convert the (optical) readings from this into a digital format so that we can datalog the information from our experiments. But with the Arduino we can take an analog ''electrical'' signal and turn it into a digital one that we can use. We have a number of choices so we need to choose the best ones for the BioBoard, where we'll be doing measurements on biological systems so the temperature range is generally the same as the one for liquid water. We want inexpensive, readily available, sensors that are easy to implement with the Arduino - and have the appropriate range, precision, and accuracy.<br /> <br /> Some of the basic types of electronic temperature sensors include:<br /> *thermocouple - excellent for very wide temperature ranges, up to 2300°C<br /> *resistance temperature detector (RTD) - used up to 600°C, often for industrial applications<br /> *thermistor - generally limited to &lt;150°C, but inexpensive<br /> *digital temperature sensor (DTS) - the output is linearly proportional to the temperature<br /> [[File:Thermometer sizes.jpg|200px|thumb|right|relative sizes of the two sensors]]<br /> <br /> The thermocouple may be seem to be the most versatile - the individual sensors can be quite inexpensive (but to make your own can mean buying enough materials for many probes) and the range large - but the millivolt output requires an amplifier (~$18) to make them compatible with the Arduino, and they have a greater range than we need. RTDs are becoming increasingly common for some applications but require a bridge circuit, and are not as inexpensive or commonly available as we would like. We chose to focus on ''both'' the thermistor and the DTS because they cover the temperature range of choice well, they are inexpensive, and they can be implemented on the Arduino easily - you get two choices, just in case you have a preference, or one is more easily available than the other. The photo shows the 2 sensors that we interfaced (the DTS is the 3 wire one), but note that the digital sensor also comes in a smaller surface mount configuration, and thermistors can be as small as a grain of sand.<br /> <br /> <br /> =Building a thermometer=<br /> <br /> Since your temperature probe will be exposed to moisture or liquid water, it is best to encase it in a waterproof sheath - a good way to do it might be to place it in a plastic tube and seal both the thermistor/DTS end and the wires coming out the far end with silicone aquarium sealant. Leave the tip of the thermistor or DTS exposed, so that you will have a good response time.<br /> <br /> ==Digital thermometer==<br /> <br /> The digital temperature sensor is the new kid on the block - it is a chip made by such manufacturers as Maxim/Dallas, Philips, and Texas Instruments, and is made to run off a voltage from 3 to 5.5 VDC, just like the Arduino puts out. We used the [[Media:Maxim-temp-sensor-DS18B20.pdf|Maxim DS18B20]] (Sparkfun and Hacktronics carry them for ~$4 but you can find them for less) and each sensor has unique 64 bit serial code stored in an onboard ROM - this allows you to use more than one sensor at a time. It is rated for the range -55°C to +125°C and has a stated accuracy of +/-.5°C in the range -10°C to +85°C.<br /> <br /> [[File:DTS-schematic.jpg|200px|thumb|right|schematic for DS18B20 DTS]]<br /> [[File:DTSprobe1.jpg|200px|thumb|right|assembling the DTS probe]]<br /> [[File:One_wire_address.JPG|200px|thumb|right|serial port results for the address finder]]<br /> ===What you need===<br /> <br /> *digital temperature sensor such as the Maxim DS18B20<br /> *1&quot; / 25mm piece of acrylic tube<br /> *Wire - you'll need 3 different colours; we suggest red for power, green for ground and white for signal<br /> *Heat shrink tubing<br /> *Aquarium / hot glue <br /> *4.7kΩ resistor<br /> <br /> ===Assembling and waterproofing it===<br /> <br /> We've been using this very good, easy-to-follow [http://www.hacktronics.com/Tutorials/arduino-1-wire-tutorial.html DTS tutorial] from Hacktronics - it'll teach you everything you need to know about interfacing with your DTS. We'll give you a quick overview, and tell you how to waterproof your DTS for use in liquids. For the detailed how-to, please see the Hacktronics tutorial.<br /> <br /> First, you have to solder the wires to the chip; remember to pull the heat shrink on ''before'' you solder the joints. Keep careful track of which of your wires goes to which legs on the sensor! Next, string the piece of acrylic tube on the wires, leaving the sensor sticking out about 1&quot; / 25mm. Fill the tube with glue, then pull on the wires to drag the sensor into the tube until the leads are fully covered.<br /> <br /> ===Interfacing and measuring===<br /> <br /> Use a solderless breadboard to build your circuit by connecting the ground / #1 leg of the DTS chip to the GND pin on your Arduino board and the VDD / #3 leg to the power strip on the breadboard. Then connect the DQ / #2 leg of the chip to an empty strip on your breadboard, and wire that to the Arduino's digital pin 3. Last, connect the strip to power / 5V using a 4.7kΩ resistor. <br /> <br /> You'll need to download the [http://www.milesburton.com/?title=Dallas_Temperature_Control_Library Dallas Temperature Control] and [http://www.pjrc.com/teensy/td_libs_OneWire.html Maxim/Dallas OneWire] libraries, and run the [http://www.hacktronics.com/code/one_wire_address_finder.zip One-Wire address finder] sketch on your Arduino board to retrieve the unique 64-bit serial code embedded in each device - follow this [http://www.hacktronics.com/Tutorials/arduino-1-wire-address-finder.html tutorial] from the nice people at Hacktronics. <br /> <br /> Once you have the address for the DTS, you can either upload the standard [http://www.hacktronics.com/code/arduino_ds18b20_temperature_sensor.zip One-Wire sketch] to your Arduino board to start measuring temperature, or use the [https://github.com/BioBridge/BioBoardArduinoCode/blob/master/temperature_sensor_NEW.pde modified version] we've made.<br /> <br /> ==Thermistor==<br /> <br /> A thermistor is a type of resistor which has a very well known dependence of the resistance on temperature, and the change is quite steep so that we can resolve small differences in temperature. We are using them in place of traditional thermometers, and so they are sometimes referred to a &quot;resistance thermometers&quot; - they are inexpensive, easy to find, and are '''very''' easy to interface to the Arduino. They are specified mainly by their room temperature (25°C) resistance and a common value is 10 kOhms. If many models are available, like from a major electronics supply house, you can also specify the tolerance and you can choose from different shapes and sizes (the size of a match head is good for starters). As well, there are two general types of thermistors - ones that increase in resistance with increasing temperature (PTC) and those that decrease in temperature with increasing temperature (NTC).<br /> <br /> ===What you need===<br /> <br /> Besides your thermistor, all you need for the circuit is a &quot;standard&quot; resistor with a value that is the same as the room temperature resistance of your thermistor. You'll be using the standard one to build a &quot;resistive divider&quot; so that you can use the 5 VDC output of the Arduino and have good resolution over the full temperature range of the thermistor (usually something like -40°C to +125°C, perfect for biological experiments). For our examples we'll be using a 10kΩ NTC thermistor (Sparkfun and Hacktronics carry these) with a 10kΩ resistor for the bridge. [[File:Thermistor-schematic.jpg|200px|thumb|right|schematic for the thermistor temperature sensor]]<br /> <br /> ===How to build it===<br /> <br /> Solder on wires and waterproof it as described for the DTS above.<br /> <br /> On a breadboard build your simple resistive divider circuit, following the schematic in the image insert.<br /> <br /> ===Things to keep in mind===<br /> <br /> R1 is the thermistor in the circuit, so your standard resistor (R2) is the one tied to the Arduino ground. When you buy the thermistor and matching resistor, buy ones with tight tolerances so that you don't have to worry about small errors in the temperature introduced by values which are off the stated values; and you might measure the actual values with a good digital multimeter, just to make sure. Take care when soldering, so that you don't expose the sensor to too high a temperature - you can fry it; before you waterproof, check the resistance one last time, just to make sure everything is still OK.<br /> <br /> ===Interfacing and measuring===<br /> <br /> Remember that the Arduino has a digital output with 10 bit (1024) resolution so for the special case where R1 is the same as R2 (that's our situation at room temperature) the voltage will be half of the Arduino's 5 VDC, so we can expect the digital output to be 1024/2 or 512. The code looks like this:<br /> <br /> double Thermistor(int RawADC) {<br /> double Temp;<br /> float resistance = (10240000/RawADC) - 10000; //calculate from voltage divider, for 10k resistor<br /> Temp = log(resistance/10000);<br /> // calculate the temperature, in K, using 4 thermistor model/material specific parameters A, B, C, D<br /> // here we use the values for the Sparkfun/Hacktronics version of the Vishay 10k NTC thermistor (from datasheet)<br /> Temp = 1 / (0.003354016 + 0.0002569850 * Temp + 0.000002620131 * Temp * Temp + 0.00000006383091 * Temp * Temp * Temp);<br /> Temp = Temp - 273.15; // Convert Kelvin to Celsius<br /> // Temp = (Temp * 9.0)/ 5.0 + 32.0; // Convert Celsius to Fahrenheit<br /> return Temp;<br /> }<br /> <br /> and the math part is the Steinhart-Hart equation, which is the relationship between the resistance and the temperature for a thermistor with certain materials properties (see here for a description). On the manufacturer's datasheet for your specific resistor you will find a list of 4 materials constants - usually referred to as A, B, C, and D - that go with it. The most general equation is: <br /> <br /> 1/T= A + B*ln(R/Rt) + C*ln(R/Rt)&lt;sup&gt;2&lt;/sup&gt; + D*ln(R/Rt)&lt;sup&gt;3&lt;/sup&gt;<br /> <br /> but check which one is appropriate for the material constants on your datasheet (the ones in this example are for Vishay thermistors which come from Sparkfun).<br /> <br /> =Calibrating a home-built thermometer=<br /> <br /> [[File:Zero_C_noise.JPG|200px|thumb|right|results when the thermistor is immersed in ice water]] [[File:Temperaturebump.JPG|200px|thumb|right|response time of the two sensors]] [[File:Double_probe_baht.jpg|200px|thumb|right|example probes for the two sensors]]<br /> <br /> Everybody needs to be convinced that your homemade instrument is reading what it should - it must be checked for calibration. Most of us only have two easily accessible, well known, temperatures in the biological region of interest that we can produce - the melting point of ice (0°C) and the boiling point of water (100°C, at sea leve)l - and these are good places to start. It can be helpful to use another reference temperature measurement technique which has already been calibrated, such as a commercial digital thermometer, in case or thermocouple (plus a reader for it - I use a Fluke instrument with an adjustable offset in case there is any error at your reference temperatures) is not available. This figure shows the results of a trial where I placed both the thermocouple and the thermistor in an ice+water bath (a double walled coffee mug) and recorded the Arduino output every 10 seconds - both instruments had an efective resolution of .1°C and we are looking at the ''noise'' at a fixed temperature.<br /> <br /> It is not uncommon to see a peak-to-peak noise level of 3 times the resolution, and that is about what the experiment shows for both the thermistor and thermocouple. Note that for this experiment the Arduino output seems to be linear with the calculated temperature, and this what we expect for relatively small changes in temperature - if we are monitoring experiments where the temperature does not change much we can simplify the mathematical relationship between resistance and temperature, avoiding the calculation hassles of the Steinhart-Hart equation. The offset of ~1.3°C between the &quot;Arduino temperature&quot; and the expected value of 0°C -(the reference thermocouple does only a little better than this unless the 0°C offset voltage is very carefully tweaked - and remember that the literature indicates that we can expect up to about 1°C error due to instrument on-board cold junction compensation errors) - is likely because this particular thermistor only has a room temperature resistance tolerance of +/-5%.

<p>Rikke: /* Thermistor */</p> <hr /> <div>=Introduction to temperature measurements=<br /> <br /> We are all familiar with the classic simple analog thermometer - the one with the resevoir of mercury or alcohol at the bottom. Unfortunately it is not very easy to convert the (optical) readings from this into a digital format so that we can datalog the information from our experiments. But with the Arduino we can take an analog ''electrical'' signal and turn it into a digital one that we can use. We have a number of choices so we need to choose the best ones for the BioBoard, where we'll be doing measurements on biological systems so the temperature range is generally the same as the one for liquid water. We want inexpensive, readily available, sensors that are easy to implement with the Arduino - and have the appropriate range, precision, and accuracy.<br /> <br /> Some of the basic types of electronic temperature sensors include:<br /> *thermocouple - excellent for very wide temperature ranges, up to 2300°C<br /> *resistance temperature detector (RTD) - used up to 600°C, often for industrial applications<br /> *thermistor - generally limited to &lt;150°C, but inexpensive<br /> *digital temperature sensor (DTS) - the output is linearly proportional to the temperature<br /> [[File:Thermometer sizes.jpg|200px|thumb|right|relative sizes of the two sensors]]<br /> <br /> The thermocouple may be seem to be the most versatile - the individual sensors can be quite inexpensive (but to make your own can mean buying enough materials for many probes) and the range large - but the millivolt output requires an amplifier (~$18) to make them compatible with the Arduino, and they have a greater range than we need. RTDs are becoming increasingly common for some applications but require a bridge circuit, and are not as inexpensive or commonly available as we would like. We chose to focus on ''both'' the thermistor and the DTS because they cover the temperature range of choice well, they are inexpensive, and they can be implemented on the Arduino easily - you get two choices, just in case you have a preference, or one is more easily available than the other. The photo shows the 2 sensors that we interfaced (the DTS is the 3 wire one), but note that the digital sensor also comes in a smaller surface mount configuration, and thermistors can be as small as a grain of sand.<br /> <br /> <br /> =Building a thermometer=<br /> <br /> Since your temperature probe will be exposed to moisture or liquid water, it is best to encase it in a waterproof sheath - a good way to do it might be to place it in a plastic tube and seal both the thermistor/DTS end and the wires coming out the far end with silicone aquarium sealant. Leave the tip of the thermistor or DTS exposed, so that you will have a good response time.<br /> <br /> ==Digital thermometer==<br /> <br /> The digital temperature sensor is the new kid on the block - it is a chip made by such manufacturers as Maxim/Dallas, Philips, and Texas Instruments, and is made to run off a voltage from 3 to 5.5 VDC, just like the Arduino puts out. We used the [[Media:Maxim-temp-sensor-DS18B20.pdf|Maxim DS18B20]] (Sparkfun and Hacktronics carry them for ~$4 but you can find them for less) and each sensor has unique 64 bit serial code stored in an onboard ROM - this allows you to use more than one sensor at a time. It is rated for the range -55°C to +125°C and has a stated accuracy of +/-.5°C in the range -10°C to +85°C.<br /> <br /> [[File:DTS schematic.JPG|200px|thumb|right|schematic for DS18B20 DTS]]<br /> [[File:DTSprobe1.jpg|200px|thumb|right|assembling the DTS probe]]<br /> [[File:One_wire_address.JPG|200px|thumb|right|serial port results for the address finder]]<br /> ===What you need===<br /> <br /> *digital temperature sensor such as the Maxim DS18B20<br /> *1&quot; / 25mm piece of acrylic tube<br /> *Wire - you'll need 3 different colours; we suggest red for power, green for ground and white for signal<br /> *Heat shrink tubing<br /> *Aquarium / hot glue <br /> *4.7kΩ resistor<br /> <br /> ===Assembling and waterproofing it===<br /> <br /> We've been using this very good, easy-to-follow [http://www.hacktronics.com/Tutorials/arduino-1-wire-tutorial.html DTS tutorial] from Hacktronics - it'll teach you everything you need to know about interfacing with your DTS. We'll give you a quick overview, and tell you how to waterproof your DTS for use in liquids. For the detailed how-to, please see the Hacktronics tutorial.<br /> <br /> First, you have to solder the wires to the chip; remember to pull the heat shrink on ''before'' you solder the joints. Keep careful track of which of your wires goes to which legs on the sensor! Next, string the piece of acrylic tube on the wires, leaving the sensor sticking out about 1&quot; / 25mm. Fill the tube with glue, then pull on the wires to drag the sensor into the tube until the leads are fully covered.<br /> <br /> ===Interfacing and measuring===<br /> <br /> Use a solderless breadboard to build your circuit by connecting the ground / #1 leg of the DTS chip to the GND pin on your Arduino board and the VDD / #3 leg to the power strip on the breadboard. Then connect the DQ / #2 leg of the chip to an empty strip on your breadboard, and wire that to the Arduino's digital pin 3. Last, connect the strip to power / 5V using a 4.7kΩ resistor. <br /> <br /> You'll need to download the [http://www.milesburton.com/?title=Dallas_Temperature_Control_Library Dallas Temperature Control] and [http://www.pjrc.com/teensy/td_libs_OneWire.html Maxim/Dallas OneWire] libraries, and run the [http://www.hacktronics.com/code/one_wire_address_finder.zip One-Wire address finder] sketch on your Arduino board to retrieve the unique 64-bit serial code embedded in each device - follow this [http://www.hacktronics.com/Tutorials/arduino-1-wire-address-finder.html tutorial] from the nice people at Hacktronics. <br /> <br /> Once you have the address for the DTS, you can either upload the standard [http://www.hacktronics.com/code/arduino_ds18b20_temperature_sensor.zip One-Wire sketch] to your Arduino board to start measuring temperature, or use the [https://github.com/BioBridge/BioBoardArduinoCode/blob/master/temperature_sensor_NEW.pde modified version] we've made.<br /> <br /> <br /> ==Thermistor==<br /> <br /> A thermistor is a type of resistor which has a very well known dependence of the resistance on temperature, and the change is quite steep so that we can resolve small differences in temperature. We are using them in place of traditional thermometers, and so they are sometimes referred to a &quot;resistance thermometers&quot; - they are inexpensive, easy to find, and are '''very''' easy to interface to the Arduino. They are specified mainly by their room temperature (25°C) resistance and a common value is 10 kOhms. If many models are available, like from a major electronics supply house, you can also specify the tolerance and you can choose from different shapes and sizes (the size of a match head is good for starters). As well, there are two general types of thermistors - ones that increase in resistance with increasing temperature (PTC) and those that decrease in temperature with increasing temperature (NTC).<br /> <br /> ===What you need===<br /> <br /> Besides your thermistor, all you need for the circuit is a &quot;standard&quot; resistor with a value that is the same as the room temperature resistance of your thermistor. You'll be using the standard one to build a &quot;resistive divider&quot; so that you can use the 5 VDC output of the Arduino and have good resolution over the full temperature range of the thermistor (usually something like -40°C to +125°C, perfect for biological experiments). For our examples we'll be using a 10kΩ NTC thermistor (Sparkfun and Hacktronics carry these) with a 10kΩ resistor for the bridge. [[File:Thermistor-schematic.jpg|200px|thumb|right|schematic for the thermistor temperature sensor]]<br /> <br /> ===How to build it===<br /> <br /> Solder on wires and waterproof it as described for the DTS above.<br /> <br /> On a breadboard build your simple resistive divider circuit, following the schematic in the image insert.<br /> <br /> ===Things to keep in mind===<br /> <br /> R1 is the thermistor in the circuit, so your standard resistor (R2) is the one tied to the Arduino ground. When you buy the thermistor and matching resistor, buy ones with tight tolerances so that you don't have to worry about small errors in the temperature introduced by values which are off the stated values; and you might measure the actual values with a good digital multimeter, just to make sure. Take care when soldering, so that you don't expose the sensor to too high a temperature - you can fry it; before you waterproof, check the resistance one last time, just to make sure everything is still OK.<br /> <br /> ===Interfacing and measuring===<br /> <br /> Remember that the Arduino has a digital output with 10 bit (1024) resolution so for the special case where R1 is the same as R2 (that's our situation at room temperature) the voltage will be half of the Arduino's 5 VDC, so we can expect the digital output to be 1024/2 or 512. The code looks like this:<br /> <br /> double Thermistor(int RawADC) {<br /> double Temp;<br /> float resistance = (10240000/RawADC) - 10000; //calculate from voltage divider, for 10k resistor<br /> Temp = log(resistance/10000);<br /> // calculate the temperature, in K, using 4 thermistor model/material specific parameters A, B, C, D<br /> // here we use the values for the Sparkfun/Hacktronics version of the Vishay 10k NTC thermistor (from datasheet)<br /> Temp = 1 / (0.003354016 + 0.0002569850 * Temp + 0.000002620131 * Temp * Temp + 0.00000006383091 * Temp * Temp * Temp);<br /> Temp = Temp - 273.15; // Convert Kelvin to Celsius<br /> // Temp = (Temp * 9.0)/ 5.0 + 32.0; // Convert Celsius to Fahrenheit<br /> return Temp;<br /> }<br /> <br /> and the math part is the Steinhart-Hart equation, which is the relationship between the resistance and the temperature for a thermistor with certain materials properties (see here for a description). On the manufacturer's datasheet for your specific resistor you will find a list of 4 materials constants - usually referred to as A, B, C, and D - that go with it. The most general equation is: <br /> <br /> 1/T= A + B*ln(R/Rt) + C*ln(R/Rt)&lt;sup&gt;2&lt;/sup&gt; + D*ln(R/Rt)&lt;sup&gt;3&lt;/sup&gt;<br /> <br /> but check which one is appropriate for the material constants on your datasheet (the ones in this example are for Vishay thermistors which come from Sparkfun).<br /> <br /> =Calibrating a home-built thermometer=<br /> <br /> [[File:Zero_C_noise.JPG|200px|thumb|right|results when the thermistor is immersed in ice water]] [[File:Temperaturebump.JPG|200px|thumb|right|response time of the two sensors]] [[File:Double_probe_baht.jpg|200px|thumb|right|example probes for the two sensors]]<br /> <br /> Everybody needs to be convinced that your homemade instrument is reading what it should - it must be checked for calibration. Most of us only have two easily accessible, well known, temperatures in the biological region of interest that we can produce - the melting point of ice (0°C) and the boiling point of water (100°C, at sea leve)l - and these are good places to start. It can be helpful to use another reference temperature measurement technique which has already been calibrated, such as a commercial digital thermometer, in case or thermocouple (plus a reader for it - I use a Fluke instrument with an adjustable offset in case there is any error at your reference temperatures) is not available. This figure shows the results of a trial where I placed both the thermocouple and the thermistor in an ice+water bath (a double walled coffee mug) and recorded the Arduino output every 10 seconds - both instruments had an efective resolution of .1°C and we are looking at the ''noise'' at a fixed temperature.<br /> <br /> It is not uncommon to see a peak-to-peak noise level of 3 times the resolution, and that is about what the experiment shows for both the thermistor and thermocouple. Note that for this experiment the Arduino output seems to be linear with the calculated temperature, and this what we expect for relatively small changes in temperature - if we are monitoring experiments where the temperature does not change much we can simplify the mathematical relationship between resistance and temperature, avoiding the calculation hassles of the Steinhart-Hart equation. The offset of ~1.3°C between the &quot;Arduino temperature&quot; and the expected value of 0°C -(the reference thermocouple does only a little better than this unless the 0°C offset voltage is very carefully tweaked - and remember that the literature indicates that we can expect up to about 1°C error due to instrument on-board cold junction compensation errors) - is likely because this particular thermistor only has a room temperature resistance tolerance of +/-5%. If measuring and then using the offset is not what you wish to do, you might have to buy one with a better tolerance and generally take extra-ordinary measures. <br /> <br /> The DTS also showed an elevated temperature when in the ice bath - +2°C in this case. This time it is a little harder to understand, and because they are so new there is not much help out there on the web (and I doubt that the vendors have much real experience with them).

<p>Rikke: /* How to build it */</p> <hr /> <div>=Introduction to optical loss=<br /> <br /> When light travels through a substance, whether it's solid, liquid or gaseous, the intensity of the light is reduced; this is called optical loss. Measuring how much the light intensity is reduced at different wavelengths is called [http://en.wikipedia.org/wiki/Spectrophotometry spectrophotometry], and can be used to determine many different properties of the substance, such as concentration of a solution or opacity of a glass pane. To do this, you need a [http://en.wikipedia.org/wiki/Photometer photometer], which is essentially a combination of a light source of known intensity and wavelength, and a light sensor which measures how much light was absorbed and/or scattered by the sample over a fixed gap.<br /> <br /> Spectrophotometry may also be applied to gain information about biological processes. Especially in microbiology, where most work is done with organisms that are too small and too numerous to easily count individually, optical loss is often used as a proxy for cell density or biomass. For instance, measuring the light absorption of chlorophyll in an algae vat may be used as a direct proxy for the algal density. <br /> <br /> In industrial production systems, such as large-scale alcohol fermentation, insulin production, etc., biological growth is often monitored using in-line ('live') sensors, which measure optical loss, usually at wavelengths in the [http://en.wikipedia.org/wiki/Infrared#Different_regions_in_the_infrared near-infrared] (NIR) or IR-A spectrum (700-1400nm). The inspiration for the home-built NIR probe described in the rest of this wiki is a [http://www.optek.com/Schematic_Single_Channel_NIR_LED_Probe.asp single-channel NIR sensor] from Optek, which emits and detects at 850nm, and is designed for in-line monitoring of yeast fermentations. <br /> <br /> =Building a NIR probe=<br /> <br /> When building a near-infrared sensor, the first important choice is that of light source (photoemitter) and sensor (photosensor). Important considerations include:<br /> *what's the appropriate wavelength(s) for your purposes?<br /> *how much circuitry do you want to build?<br /> *how much can you afford to invest?<br /> <br /> This design uses an 850nm plastic LED (Everlight HIR204 - $0.43) as the photoemitter, and a matching phototransistor (Optek OP506B - $0.80) as the photosensor, both of which are available at a variety of on-line electronics stores, at least in the U.S. - any equivalent pair should work as well, but resistance on the circuitry and parts of the Arduino code may need tweaking. For the HIR204/OP506B couple, the required circuitry is limited to a couple of resistors. <br /> <br /> ==Things to keep in mind==<br /> <br /> When designing a probe for measuring biological processes, it's important to use biologically inert materials; this means that the materials you use should be non-toxic, but also non-biodegrabable. Acrylic, polycarbonate and stainless steel all fit the bill, but vary considerably in price, availability and workability. PVC is opposed by some, on the grounds that species of bacteria have been discovered that can degrade it rapidly - whether these are likely to be present in your specific culture is an open question.<br /> <br /> Food safety is another consideration. We've used hot glue for our initial prototypes, because although hot glue is probably not food safe (can't find any sources to verify / falsify this), in this design it is encased in acrylic. We will switch to aquarium glue in the final edition, though, on the assumption that as fish are extremely sensitive to water quality and don't suffer ill effects from it, it's likely to be safe for humans, too. <br /> <br /> Last, but not least: this should go without saying, but make sure you ''don't'' get a glue with anti-fungal / bacterial / microbial properties - you want those critters to live so you can study them, right?<br /> <br /> ==What you need==<br /> <br /> *1x IR LED<br /> *1x Phototransistor<br /> *1x 1kΩ resistor<br /> *1x 100Ω resistor<br /> *1x Soldering iron + solder<br /> *1x 3/4&quot; / 20mm acrylic tube<br /> *4x 3/4&quot; / 20mm acrylic discs<br /> *1x 1&quot; / 25mm PVC pipe<br /> *Acrylic cement (thick)<br /> *Wire<br /> *Aquarium glue/hot glue <br /> <br /> Optional: cell-phone motor (BubbleShaker Technology)<br /> <br /> Here's a quick [[Media:NIR_probe_schematic.jpg|hand-drawn sketch]] of our NIR probe to give you an overview of the construction described below.<br /> <br /> ==How to build it==<br /> <br /> [[File:IMG259.jpg|200px|thumb|right|Step 1: probe parts]] [[File:NIRprobe2.jpg|200px|thumb|Step 3: assembling]] [[File:NIRprobe3.jpg|200px|thumb|right|Step 4: waterproofing]] [[File:NIRprobe4.jpg|200px|thumb|right|Step 5: spacing]]<br /> <br /> '''Step 1: Cutting acrylic'''<br /> <br /> Start by cutting the 3/4&quot; acrylic tube into 2 x 1&quot; / 25mm pieces (A1 and A2) and 1 x 3/4&quot; / 20mm piece (A3). Make a slit in A3 approx. 1/3&quot; / 8mm wide by making two cuts that run the entire length of the tube. Acrylic is very easy to cut with a small rotor tool (e.g. a Dreml), but you can also use a small hacksaw. Files or fine sandpaper are good for smoothing rough edges and planing not-quite-perpendicular cuts.<br /> <br /> <br /> '''Step 2: Soldering wires'''<br /> <br /> Cut the leads on both the LED and the phototransistor about 30% shorter. Solder wires onto the leads, and make sure to note down what colour wire you use for the different leads! These are polar devices and won't work if you wire them up backwards. We suggest you use red for both power / emitter leads, black for the ground lead on the LED, and white for the collector lead on the phototransistor. <br /> <br /> <br /> '''Step 3: Assembling'''<br /> <br /> Drill a 3mm (or as close as you can get with Imperial units) hole in the center of each acrylic disc. Take two of the discs, carefully lay down a narrow line of acrylic cement around the holes, then insert the LED and phototransistor in the holes, and set them aside to cure. When the acrylic discs with the LED and phototransistor have properly cured, thread A1 and A2 on one set of wires each, lay a fat line of acrylic cement along the edge of both discs and press A1 and A2 firmly into place, creating a lidded, cylindrical chamber for the leads. Leave to cure. Reinforce the seal by laying down another line of acrylic cement along the joint between the tubes and the discs.<br /> <br /> <br /> '''Step 4: Waterproofing'''<br /> <br /> Waterproof each chamber completely by filling it out with aquarium / hot glue, then immediately string the last two acrylic discs onto the wires and glue them to the tubes with acrylic cement. Leave to cure, then reinforce the seal from the outside with another line of acrylic cement. <br /> <br /> <br /> '''Step 5: Spacing''' <br /> <br /> Once the aquarium / hot glue has cured properly, take A3, place it between the two acrylic discs holding the LED and phototransistor, and glue the three parts together with acrylic cement, then leave to dry.<br /> <br /> <br /> '''Step 6: Blocking sunlight with PVC (optional)'''<br /> <br /> Since sunlight includes lots of infrared radiation, it may be necessary to shield your probe. A very simple way of doing this is to take length of PVC tube with a tight-fitting cap, make a hole in the cap for wires, and simply pull the tube + cap over your NIR probe like a lampshade. Making sure the phototransistor is pointing downwards also helps. <br /> <br /> <br /> '''Bonus level: Building the BubbleShakerTM (optional)'''<br /> <br /> Some biological processes form gas (usually C02), which may cause bubbles to form on the surface of the LED and phototransistor and throw off your measurements. To solve this problem, we've created the amazing BubbleShakerTM - a small off-set motor ('buzzer') extracted from an old cell phone, encased in a short piece of acrylic tube plugged with aquarium / hot glue on both ends. <br /> <br /> To build one yourself, the first thing you'll have to do is find an old cell phone somewhere, crack it open, and extract the motor - get as much of the wires as you can, it'll make life easier for you when you have to solder extensions on. Solder about 2 ft / 60cm of additional wire (remember the colours) to both leads. Then take a piece of acrylic tube big enough to fit the motor and about 1/2&quot; / 13mm wire and plug one end with glue. Insert the motor in the tube - make sure fits tightly by wrapping the fixed part in electrical / gaffer tape, taking care not to block the rotor. Plug the other end of the tube carefully with glue, covering the soldered joint for extra strength.<br /> <br /> Attach the BubbleShakerTM to your NIR probe by grinding one side of the tube flat, doing the same to the LED end of the probe, and glueing the two together with acrylic cement. There's a picture of a fully assembled unit [[Media:NIRprobe7.jpg|here]].<br /> <br /> =Interfacing and measuring=<br /> <br /> [[File:NIRprobe6.jpg|200px|thumb|right|Connecting to Arduino]]<br /> <br /> After assembling the probe, you'll need to wire it up to some kind of microcontroller; we've used an Arduino clone called [http://www.ladyada.net/make/boarduino/ BoArduino], and will use that as example, but you can use any type you like. Start out by connecting the 5V and GND pins on the Arduino to the power (+ / red) and ground (- / blue / black) strips on the breadboard. Then wire the LED to 5V and GND across a 150Ω resistor. Now connect the collector lead on the phototransistor to 5V, and the emitter lead to an empty strip on the breadboard, then wire that strip to the A1 pin on the Arduino with a connector, and to ground with a 100Ω resistor. If you've built the bonus version, you'll also need to wire your BubbleShaker to 5V and GND. Then you're ready to hook the Arduino board up to your computer, program it and start recording.<br /> <br /> In order to program the the BoArduino, you have to download and install the [http://arduino.cc/en/Main/Software Arduino software] first. Once this is done, you're ready to connect your board - in some cases, this requires a special cable, so make sure you've got the right one! Now open this [https://github.com/BioBridge/BioBoardArduinoCode/blob/master/NIR_sensor_demo.pde Arduino sketch] and hit upload. Open the serial monitor to see the print-out of the data being transmitted from the probe, which ought to look more or less like this: @NIR:0:0.99$.<br /> <br /> <br /> =Calibrating=<br /> <br /> Calibrating measuring equipment is an important part of any scientific pursuit, because the accuracy of your calibration determines the reliability of your data. However, when it comes to biomass and cell density, determining absolute values may be somewhat difficult, so you might want consider whether you actually need to know; in a lot of cases, you are likely to be less interested in the absolute biomass than in the relative change in biomass over time. <br /> <br /> To get an absolute measure of biomass in a live microbial culture, you can use several different techniques:<br /> * counting cells in a special microscope chamber<br /> * marking cells with radioactive isotopes and counting scintillation events <br /> * incubating on solid substrates overnight and counting the resulting colonies <br /> * desiccating samples to measure total dry organic matter by weight<br /> <br /> All of these techniques will require special equipment, though, and multiple measurements over time to create enough data to draw reliable calibration curves and compare your NIR probe values to those curves. We're not going to go into detail with any of that here - Google will help you learn more if you want - but merely describe the ways in which you can adjust your probe if you need to.<br /> <br /> The easiest way to calibrate this NIR probe is by tweaking the Arduino sketch. Use a voltmeter to measure the voltage coming off the leads from the phototransistor directly when the probe is just sitting in air (should be close to 5V), and simply enter that value instead of the default IMAX value in the calibration settings:<br /> <br /> // CALIBRATION SETTINGS<br /> #define IMAX 4.9 /* max phototransistor current with IR LED on (no obstructions, just 1inch air) */<br /> #define IMIN 0.02 /* dark current (NOTUSED) */<br /> #define VMAX 5.0 /* arduino voltage = 5.0v */<br /> #define ADCMAX 1023 /* highest ADC value */<br /> #define IMAXI (ADCMAX*IMAX/VMAX) /* highest ADC value we expect from our sensor */<br /> #define IMAXI_INV (1.0/(ADCMAX*IMAX/VMAX)) /* inverse (this avoids a divide during runtime) */<br /> <br /> An initial test of your probe in the most and least dense cultures you plan to monitor should then tell you whether you can actually measure across the relevant range. <br /> <br /> If you have problems covering the whole spectrum, the other two things you can adjust relatively easily are the distance between the LED and the phototransistor, and the resistance on the circuit. A low resistance potentiometer instead of the 100Ω resistor on the emitter lead would allow you to adjust the sensitivity of the phototransistor directly, and provide a way of tuning it without having to disassemble and rebuild it. You can also decrease the light intensity of the LED by increasing the value of the resistor; 470Ω seems to be a good mid-level.<br /> <br /> =Geeking out= <br /> <br /> The reduction in intensity of light passing through a mass is due to a combination of reflection, absorption and scattering - the relative importance of these depends on the specific properties of the mass or substance, and for any given substance will vary with the wavelength of the light. When measuring directly in liquids, surface reflection is obviously not contributing to optical loss, thus the reduction in light intensity is entirely due to absorption and/or scattering.<br /> <br /> Most chemical substances absorb light in the visible spectrum, but don't absorb or scatter much in the infrared spectrum. Conversely, with the exception of chlorophyll-containing algae and bacteria, microbiological cells generally block / scatter IR light, but don't absorb or scatter much in the visible spectrum, which is also why they appear colourless or even translucent under a microscope. Thus, a sensor measuring optical loss in the near-infrared part of the radiation spectrum (850nm in our case) will generally be much more responsive to biomass / cell density than to any (inorganic) chemical compounds present in the medium. <br /> <br /> <br /> =Making it cooler=<br /> <br /> Streamlining and verifying our current design is going to be a high priority, but we are also considering possible future develoments. One potential future improvement on the current design could be inspired by another commercial NIR probe called [Media:TruCell.TN.AUvsOD.pdf|TruCell], which uses a laser diode as lightemitter, enabling measurements at much higher cell densities. Another developement could be the construction of either a full-spectrum spectrophotometer - likely very problematic to scale down far enough to fit in a piece of 1&quot; PVC tube - or a probe with several emitter/sensor pairs that would allow us to measure at several wavelengths at once.<br /> <br /> =Links=<br /> <br /> External links from the text above and additional resources<br /> *[http://en.wikipedia.org/wiki/Spectrophotometry] Wikipedia article on spectrophotometry<br /> *[http://en.wikipedia.org/wiki/Photometer] Wikipedia article on photometers<br /> *[http://en.wikipedia.org/wiki/Infrared#Different_regions_in_the_infrared] Wikipedia article on infrared radiation<br /> *[http://www.optek.com/Schematic_Single_Channel_NIR_LED_Probe.asp] Single-channel NIR sensor from Optek<br /> *[http://arduino.cc/en/Main/Software] The Arduino IDE</div>

<p>Rikke: /* BioBoard subpages */</p> <hr /> <div>=Abstract=<br /> <br /> &quot;The BioBoard&quot; is an Arduino-controlled sensor package that allow users to monitor a range of physiochemical factors related to microbiological processes (e.g. algae growing, youghurt production, kombucha fermentation, sourdough culturing, etc.) in liquid media/cultures, with real-time data transmission and graphic data visualization designed to make key correlations between these factors easily graspable.<br /> <br /> <br /> =Goals / Features=<br /> <br /> As a minimum, we want to be able to monitor temperature, pH and dissolved oxygen. We'd also like to be able to measure biomass, either directly or by proxy. The current plan is to build a thermometer, a dissolved oxygen sensor and a biomass probe ourselves, and supplementing with a commercial pH meter. Failing that, we'll buy a thermometer and an oxygen probe as well and attempt to hack them instead, and concentrate on standardising data protocols, building the supporting controller hardware and making the graphics look pretty.<br /> <br /> =Hardware=<br /> <br /> ==Sensors== <br /> <br /> Important considerations are affordability, accessibility and required precision. Biologically relevant temperature range is approx. 0-100°C; accuracy should not be less than ±0.5°C at 25-35°C. pH range is (1-14), and required precision is approx. ±0.5, preferably better. dO probe should be able to measure % conc. with an accuracy of approx. ±2%, preferably better.

The current plan is to build a thermometer, a dissolved oxygen sensor and a biomass probe ourselves, and supplementing with a commercial pH meter. Failing that, we'll buy a thermometer and an oxygen probe as well and attempt to hack them instead, and concentrate on standardising data protocols, building the supporting controller hardware and making the graphics look pretty.<br /> <br /> =Hardware=<br /> <br /> ==Sensors== <br /> <br /> Important considerations are affordability, accessibility and required precision. Biologically relevant temperature range is approx. 0-100°C; accuracy should not be less than ±0.5°C at 25-35°C. pH range is (1-14), and required precision is approx. ±0.5, preferably better. dO probe should be able to measure % conc. with an accuracy of approx. ±2%, preferably better. Biomass probe will likely be measuring absorbance as a proxy for total biomass, and can be validated using classic spectrophotometer and CFU count.<br /> <br /> ===Thermometer=== <br /> <br /> '''[http://en.wikipedia.org/wiki/Thermocouple Thermocouples (TCs)]'''<br /> <br /> Pros<br /> * Very robust, good for nasty environments <br /> * Wide temperature range (−200°C to +1350°C for type K)<br /> * Relatively cheap (approx. $15 for a DIY model incl. amplifier)<br /> Cons<br /> * Voltage is very small so requires an amplifier with digital out (41 µV/°C for type K)<br /> <br /> '''Digital Temperature Sensors (DTS)'''<br /> <br /> Pros<br /> * Avaliable as one-wire devices, use single digital pin <br /> * Require no amplification or moderation to connect to Arduino<br /> * Good precision in biological range <br /> ** ±0.5°C accuracy from –10°C to +85°C for DS1820<br /> * Very cheap ($0.75 to $3.95)<br /> Cons<br /> * Comparatively limited temperature range<br /> ** –55°C to +125°C for DS1820<br /> ** -40°C to +125°C for TC1047A<br /> * Accuracy only ±2°C for TC1047A at 25°C<br /> * Sensitive to mechanical damage and liquid, so require protection/casing<br /> <br /> '''Thermistors'''<br /> <br /> Pros<br /> * Single analog pin use<br /> * Very cheap ($1.75 from Hacktronics)<br /> Cons<br /> * Comparatively limited temperature range (-40°C to +125°C)<br /> * Accuracy approx. ±1°C at 25°C<br /> <br /> <br /> '''Commercial resources'''<br /> <br /> TCs<br /> * [http://www.omega.com/ppt/pptsc.asp?ref=HTTC36 Hollow Tube Thermocouple Probe] - $19 from Omega <br /> TC wire<br /> * [http://www.mcmaster.com/#type-k-thermocouple-wire/=bkaksl, both wires in a sheath] ~$1/foot, by the foot from McMaster Carr <br /> * Omega [http://www.omega.com/ppt/pptsc.asp?ref=SPIR&amp;Nav=temh02 bare wire is here].

<p>Rikke: /* Calibrating */</p> <hr /> <div>=Introduction to optical loss=<br /> <br /> When light travels through a substance, whether it's solid, liquid or gaseous, the intensity of the light is reduced; this is called optical loss. Measuring how much the light intensity is reduced at different wavelengths is called [http://en.wikipedia.org/wiki/Spectrophotometry spectrophotometry], and can be used to determine many different properties of the substance, such as concentration of a solution or opacity of a glass pane. To do this, you need a [http://en.wikipedia.org/wiki/Photometer photometer], which is essentially a combination of a light source of known intensity and wavelength, and a light sensor which measures how much light was absorbed and/or scattered by the sample over a fixed gap.<br /> <br /> Spectrophotometry may also be applied to gain information about biological processes. Especially in microbiology, where most work is done with organisms that are too small and too numerous to easily count individually, optical loss is often used as a proxy for cell density or biomass. For instance, measuring the light absorption of chlorophyll in an algae vat may be used as a direct proxy for the algal density. <br /> <br /> In industrial production systems, such as large-scale alcohol fermentation, insulin production, etc., biological growth is often monitored using in-line ('live') sensors, which measure optical loss, usually at wavelengths in the [http://en.wikipedia.org/wiki/Infrared#Different_regions_in_the_infrared near-infrared] (NIR) or IR-A spectrum (700-1400nm). The inspiration for the home-built NIR probe described in the rest of this wiki is a [http://www.optek.com/Schematic_Single_Channel_NIR_LED_Probe.asp single-channel NIR sensor] from Optek, which emits and detects at 850nm, and is designed for in-line monitoring of yeast fermentations. <br /> <br /> =Building a NIR probe=<br /> <br /> When building a near-infrared sensor, the first important choice is that of light source (photoemitter) and sensor (photosensor). Important considerations include:<br /> *what's the appropriate wavelength(s) for your purposes?<br /> *how much circuitry do you want to build?<br /> *how much can you afford to invest?<br /> <br /> This design uses an 850nm plastic LED (Everlight HIR204 - $0.43) as the photoemitter, and a matching phototransistor (Optek OP506B - $0.80) as the photosensor, both of which are available at a variety of on-line electronics stores, at least in the U.S. - any equivalent pair should work as well, but resistance on the circuitry and parts of the Arduino code may need tweaking. For the HIR204/OP506B couple, the required circuitry is limited to a couple of resistors. <br /> <br /> ==Things to keep in mind==<br /> <br /> When designing a probe for measuring biological processes, it's important to use biologically inert materials; this means that the materials you use should be non-toxic, but also non-biodegrabable. Acrylic, polycarbonate and stainless steel all fit the bill, but vary considerably in price, availability and workability. PVC is opposed by some, on the grounds that species of bacteria have been discovered that can degrade it rapidly - whether these are likely to be present in your specific culture is an open question.<br /> <br /> Food safety is another consideration. We've used hot glue for our initial prototypes, because although hot glue is probably not food safe (can't find any sources to verify / falsify this), in this design it is encased in acrylic. We will switch to aquarium glue in the final edition, though, on the assumption that as fish are extremely sensitive to water quality and don't suffer ill effects from it, it's likely to be safe for humans, too. <br /> <br /> Last, but not least: this should go without saying, but make sure you ''don't'' get a glue with anti-fungal / bacterial / microbial properties - you want those critters to live so you can study them, right?<br /> <br /> ==What you need==<br /> <br /> *1x IR LED<br /> *1x Phototransistor<br /> *1x 1kΩ resistor<br /> *1x 100Ω resistor<br /> *1x Soldering iron + solder<br /> *1x 3/4&quot; / 20mm acrylic tube<br /> *4x 3/4&quot; / 20mm acrylic discs<br /> *1x 1&quot; / 25mm PVC pipe<br /> *Acrylic cement (thick)<br /> *Wire<br /> *Aquarium glue/hot glue <br /> <br /> Optional: cell-phone motor (BubbleShaker Technology)<br /> <br /> Here's a quick [[Media:NIR_probe_schematic.jpg|hand-drawn sketch]] of our NIR probe to give you an overview of the construction described below.<br /> <br /> ==How to build it==<br /> <br /> [[File:IMG259.jpg|200px|thumb|right|Step 1: probe parts]] [[File:NIRprobe2.jpg|200px|thumb|Step 3: assembling]] [[File:NIRprobe3.jpg|200px|thumb|right|Step 4: waterproofing]] [[File:NIRprobe4.jpg|200px|thumb|right|Step 5: spacing]]<br /> <br /> '''Step 1: Cutting acrylic'''<br /> <br /> Start by cutting the 3/4&quot; acrylic tube into 2 x 1&quot; / 25mm pieces (A1 and A2) and 1 x 3/4&quot; / 20mm piece (A3). Make a slit in A3 approx. 1/3&quot; / 8mm wide by making two cuts that run the entire length of the tube. Acrylic is very easy to cut with a small rotor tool (e.g. a Dreml), but you can also use a small hacksaw. Files or fine sandpaper are good for smoothing rough edges and planing not-quite-perpendicular cuts.<br /> <br /> <br /> '''Step 2: Soldering wires'''<br /> <br /> Cut the leads on both the LED and the phototransistor about 30% shorter. Solder wires onto the leads, and make sure to note down what colour wire you use for the different leads! These are polar devices and won't work if you wire them up backwards. We suggest you use red for both power / emitter leads, black for the ground lead on the LED, and white for the collector lead on the phototransistor. <br /> <br /> <br /> '''Step 3: Assembling'''<br /> <br /> Drill a 3mm (or as close as you can get with Imperial units) hole in the center of each acrylic disc. Take two of the discs, carefully lay down a narrow line of acrylic cement around the holes, then insert the LED and phototransistor in the holes, and set them aside to cure. When the acrylic discs with the LED and phototransistor have properly cured, thread A1 and A2 on one set of wires each, lay a fat line of acrylic cement along the edge of both discs and press A1 and A2 firmly into place, creating a lidded, cylindrical chamber for the leads. Leave to cure. Reinforce the seal by laying down another line of acrylic cement along the joint between the tubes and the discs.<br /> <br /> <br /> '''Step 4: Waterproofing'''<br /> <br /> Waterproof each chamber completely by filling it out with aquarium / hot glue, then immediately string the last two acrylic discs onto the wires and glue them to the tubes with acrylic cement. Leave to cure, then reinforce the seal from the outside with another line of acrylic cement. <br /> <br /> <br /> '''Step 5: Spacing''' <br /> <br /> Once the aquarium / hot glue has cured properly, take A3, place it between the two acrylic discs holding the LED and phototransistor, and glue the three parts together with acrylic cement, then leave to dry.<br /> <br /> <br /> '''Step 6: Blocking sunlight with PVC (optional)'''<br /> <br /> Since sunlight includes lots of infrared radiation, it may be necessary to shield your probe. A very simple way of doing this is to take length of PVC tube with a tight-fitting cap, make a hole in the cap for wires, and simply pull the tube + cap over your NIR probe like a lampshade. Making sure the phototransistor is pointing downwards also helps. <br /> <br /> <br /> '''Bonus level: Building the BubbleShakerTM (optional)'''<br /> <br /> Some biological processes form gas (usually C02), which may cause bubbles to form on the surface of the LED and phototransistor and throw off your measurements. To solve this problem, we've created the amazing BubbleShakerTM - a small off-set motor ('buzzer') extracted from an old cell phone, encased in a short piece of acrylic tube plugged with aquarium / hot glue on both ends. <br /> <br /> To build one yourself, the first thing you'll have to do is find an old cell phone somewhere, crack it open, and extract the motor - get as much of the wires as you can, it'll make life easier for you when you have to solder extensions on. Solder about 2 ft / 60cm of additional wire (remember the colours) to both leads. Then take a piece of acrylic tube big enough to fit the motor and about 1/2&quot; / 13mm wire and plug one end with glue. Insert the motor in the tube - make sure fits tightly by wrapping the fixed part in electrical / gaffer tape, taking care not to block the rotor. Plug the other end of the tube carefully with glue, covering the soldered joint for extra strength.<br /> <br /> Attach the BubbleShakerTM to your NIR probe by grinding one side of the tube flat, doing the same to the LED end of the probe, and glueing the two together with acrylic cement. There's a picture of a fully assembled unit [[Media:NIRprobe5.jpg|here]].<br /> <br /> =Interfacing and measuring=<br /> <br /> [[File:NIRprobe6.jpg|200px|thumb|right|Connecting to Arduino]]<br /> <br /> After assembling the probe, you'll need to wire it up to some kind of microcontroller; we've used an Arduino clone called [http://www.ladyada.net/make/boarduino/ BoArduino], and will use that as example, but you can use any type you like. Start out by connecting the 5V and GND pins on the Arduino to the power (+ / red) and ground (- / blue / black) strips on the breadboard. Then wire the LED to 5V and GND across a 150Ω resistor. Now connect the collector lead on the phototransistor to 5V, and the emitter lead to an empty strip on the breadboard, then wire that strip to the A1 pin on the Arduino with a connector, and to ground with a 100Ω resistor. If you've built the bonus version, you'll also need to wire your BubbleShaker to 5V and GND. Then you're ready to hook the Arduino board up to your computer, program it and start recording.<br /> <br /> In order to program the the BoArduino, you have to download and install the [http://arduino.cc/en/Main/Software Arduino software] first. Once this is done, you're ready to connect your board - in some cases, this requires a special cable, so make sure you've got the right one! Now open this [https://github.com/BioBridge/BioBoardArduinoCode/blob/master/NIR_sensor_demo.pde Arduino sketch] and hit upload. Open the serial monitor to see the print-out of the data being transmitted from the probe, which ought to look more or less like this: @NIR:0:0.99$.<br /> <br /> <br /> =Calibrating=<br /> <br /> Calibrating measuring equipment is an important part of any scientific pursuit, because the accuracy of your calibration determines the reliability of your data. However, when it comes to biomass and cell density, determining absolute values may be somewhat difficult, so you might want consider whether you actually need to know; in a lot of cases, you are likely to be less interested in the absolute biomass than in the relative change in biomass over time. <br /> <br /> To get an absolute measure of biomass in a live microbial culture, you can use several different techniques:<br /> * counting cells in a special microscope chamber<br /> * marking cells with radioactive isotopes and counting scintillation events <br /> * incubating on solid substrates overnight and counting the resulting colonies <br /> * desiccating samples to measure total dry organic matter by weight<br /> <br /> All of these techniques will require special equipment, though, and multiple measurements over time to create enough data to draw reliable calibration curves and compare your NIR probe values to those curves. We're not going to go into detail with any of that here - Google will help you learn more if you want - but merely describe the ways in which you can adjust your probe if you need to.<br /> <br /> The easiest way to calibrate this NIR probe is by tweaking the Arduino sketch. Use a voltmeter to measure the voltage coming off the leads from the phototransistor directly when the probe is just sitting in air (should be close to 5V), and simply enter that value instead of the default IMAX value in the calibration settings:<br /> <br /> // CALIBRATION SETTINGS<br /> #define IMAX 4.9 /* max phototransistor current with IR LED on (no obstructions, just 1inch air) */<br /> #define IMIN 0.02 /* dark current (NOTUSED) */<br /> #define VMAX 5.0 /* arduino voltage = 5.0v */<br /> #define ADCMAX 1023 /* highest ADC value */<br /> #define IMAXI (ADCMAX*IMAX/VMAX) /* highest ADC value we expect from our sensor */<br /> #define IMAXI_INV (1.0/(ADCMAX*IMAX/VMAX)) /* inverse (this avoids a divide during runtime) */<br /> <br /> An initial test of your probe in the most and least dense cultures you plan to monitor should then tell you whether you can actually measure across the relevant range. <br /> <br /> If you have problems covering the whole spectrum, the other two things you can adjust relatively easily are the distance between the LED and the phototransistor, and the resistance on the circuit. A low resistance potentiometer instead of the 100Ω resistor on the emitter lead would allow you to adjust the sensitivity of the phototransistor directly, and provide a way of tuning it without having to disassemble and rebuild it. You can also decrease the light intensity of the LED by increasing the value of the resistor; 470Ω seems to be a good mid-level.<br /> <br /> =Geeking out= <br /> <br /> The reduction in intensity of light passing through a mass is due to a combination of reflection, absorption and scattering - the relative importance of these depends on the specific properties of the mass or substance, and for any given substance will vary with the wavelength of the light. When measuring directly in liquids, surface reflection is obviously not contributing to optical loss, thus the reduction in light intensity is entirely due to absorption and/or scattering.<br /> <br /> Most chemical substances absorb light in the visible spectrum, but don't absorb or scatter much in the infrared spectrum. Conversely, with the exception of chlorophyll-containing algae and bacteria, microbiological cells generally block / scatter IR light, but don't absorb or scatter much in the visible spectrum, which is also why they appear colourless or even translucent under a microscope. Thus, a sensor measuring optical loss in the near-infrared part of the radiation spectrum (850nm in our case) will generally be much more responsive to biomass / cell density than to any (inorganic) chemical compounds present in the medium. <br /> <br /> <br /> =Making it cooler=<br /> <br /> Streamlining and verifying our current design is going to be a high priority, but we are also considering possible future develoments. One potential future improvement on the current design could be inspired by another commercial NIR probe called [Media:TruCell.TN.AUvsOD.pdf|TruCell], which uses a laser diode as lightemitter, enabling measurements at much higher cell densities. Another developement could be the construction of either a full-spectrum spectrophotometer - likely very problematic to scale down far enough to fit in a piece of 1&quot; PVC tube - or a probe with several emitter/sensor pairs that would allow us to measure at several wavelengths at once.<br /> <br /> =Links=<br /> <br /> External links from the text above and additional resources<br /> *[http://en.wikipedia.org/wiki/Spectrophotometry] Wikipedia article on spectrophotometry<br /> *[http://en.wikipedia.org/wiki/Photometer] Wikipedia article on photometers<br /> *[http://en.wikipedia.org/wiki/Infrared#Different_regions_in_the_infrared] Wikipedia article on infrared radiation<br /> *[http://www.optek.com/Schematic_Single_Channel_NIR_LED_Probe.asp] Single-channel NIR sensor from Optek<br /> *[http://arduino.cc/en/Main/Software] The Arduino IDE</div>

<p>Rikke: /* Calibrating */</p> <hr /> <div>=Introduction to optical loss=<br /> <br /> When light travels through a substance, whether it's solid, liquid or gaseous, the intensity of the light is reduced; this is called optical loss. Measuring how much the light intensity is reduced at different wavelengths is called [http://en.wikipedia.org/wiki/Spectrophotometry spectrophotometry], and can be used to determine many different properties of the substance, such as concentration of a solution or opacity of a glass pane. To do this, you need a [http://en.wikipedia.org/wiki/Photometer photometer], which is essentially a combination of a light source of known intensity and wavelength, and a light sensor which measures how much light was absorbed and/or scattered by the sample over a fixed gap.<br /> <br /> Spectrophotometry may also be applied to gain information about biological processes. Especially in microbiology, where most work is done with organisms that are too small and too numerous to easily count individually, optical loss is often used as a proxy for cell density or biomass. For instance, measuring the light absorption of chlorophyll in an algae vat may be used as a direct proxy for the algal density. <br /> <br /> In industrial production systems, such as large-scale alcohol fermentation, insulin production, etc., biological growth is often monitored using in-line ('live') sensors, which measure optical loss, usually at wavelengths in the [http://en.wikipedia.org/wiki/Infrared#Different_regions_in_the_infrared near-infrared] (NIR) or IR-A spectrum (700-1400nm). The inspiration for the home-built NIR probe described in the rest of this wiki is a [http://www.optek.com/Schematic_Single_Channel_NIR_LED_Probe.asp single-channel NIR sensor] from Optek, which emits and detects at 850nm, and is designed for in-line monitoring of yeast fermentations. <br /> <br /> =Building a NIR probe=<br /> <br /> When building a near-infrared sensor, the first important choice is that of light source (photoemitter) and sensor (photosensor). Important considerations include:<br /> *what's the appropriate wavelength(s) for your purposes?<br /> *how much circuitry do you want to build?<br /> *how much can you afford to invest?<br /> <br /> This design uses an 850nm plastic LED (Everlight HIR204 - $0.43) as the photoemitter, and a matching phototransistor (Optek OP506B - $0.80) as the photosensor, both of which are available at a variety of on-line electronics stores, at least in the U.S. - any equivalent pair should work as well, but resistance on the circuitry and parts of the Arduino code may need tweaking. For the HIR204/OP506B couple, the required circuitry is limited to a couple of resistors. <br /> <br /> ==Things to keep in mind==<br /> <br /> When designing a probe for measuring biological processes, it's important to use biologically inert materials; this means that the materials you use should be non-toxic, but also non-biodegrabable. Acrylic, polycarbonate and stainless steel all fit the bill, but vary considerably in price, availability and workability. PVC is opposed by some, on the grounds that species of bacteria have been discovered that can degrade it rapidly - whether these are likely to be present in your specific culture is an open question.<br /> <br /> Food safety is another consideration. We've used hot glue for our initial prototypes, because although hot glue is probably not food safe (can't find any sources to verify / falsify this), in this design it is encased in acrylic. We will switch to aquarium glue in the final edition, though, on the assumption that as fish are extremely sensitive to water quality and don't suffer ill effects from it, it's likely to be safe for humans, too. <br /> <br /> Last, but not least: this should go without saying, but make sure you ''don't'' get a glue with anti-fungal / bacterial / microbial properties - you want those critters to live so you can study them, right?<br /> <br /> ==What you need==<br /> <br /> *1x IR LED<br /> *1x Phototransistor<br /> *1x 1kΩ resistor<br /> *1x 100Ω resistor<br /> *1x Soldering iron + solder<br /> *1x 3/4&quot; / 20mm acrylic tube<br /> *4x 3/4&quot; / 20mm acrylic discs<br /> *1x 1&quot; / 25mm PVC pipe<br /> *Acrylic cement (thick)<br /> *Wire<br /> *Aquarium glue/hot glue <br /> <br /> Optional: cell-phone motor (BubbleShaker Technology)<br /> <br /> Here's a quick [[Media:NIR_probe_schematic.jpg|hand-drawn sketch]] of our NIR probe to give you an overview of the construction described below.<br /> <br /> ==How to build it==<br /> <br /> [[File:IMG259.jpg|200px|thumb|right|Step 1: probe parts]] [[File:NIRprobe2.jpg|200px|thumb|Step 3: assembling]] [[File:NIRprobe3.jpg|200px|thumb|right|Step 4: waterproofing]] [[File:NIRprobe4.jpg|200px|thumb|right|Step 5: spacing]]<br /> <br /> '''Step 1: Cutting acrylic'''<br /> <br /> Start by cutting the 3/4&quot; acrylic tube into 2 x 1&quot; / 25mm pieces (A1 and A2) and 1 x 3/4&quot; / 20mm piece (A3). Make a slit in A3 approx. 1/3&quot; / 8mm wide by making two cuts that run the entire length of the tube. Acrylic is very easy to cut with a small rotor tool (e.g. a Dreml), but you can also use a small hacksaw. Files or fine sandpaper are good for smoothing rough edges and planing not-quite-perpendicular cuts.<br /> <br /> <br /> '''Step 2: Soldering wires'''<br /> <br /> Cut the leads on both the LED and the phototransistor about 30% shorter. Solder wires onto the leads, and make sure to note down what colour wire you use for the different leads! These are polar devices and won't work if you wire them up backwards. We suggest you use red for both power / emitter leads, black for the ground lead on the LED, and white for the collector lead on the phototransistor. <br /> <br /> <br /> '''Step 3: Assembling'''<br /> <br /> Drill a 3mm (or as close as you can get with Imperial units) hole in the center of each acrylic disc. Take two of the discs, carefully lay down a narrow line of acrylic cement around the holes, then insert the LED and phototransistor in the holes, and set them aside to cure. When the acrylic discs with the LED and phototransistor have properly cured, thread A1 and A2 on one set of wires each, lay a fat line of acrylic cement along the edge of both discs and press A1 and A2 firmly into place, creating a lidded, cylindrical chamber for the leads. Leave to cure. Reinforce the seal by laying down another line of acrylic cement along the joint between the tubes and the discs.<br /> <br /> <br /> '''Step 4: Waterproofing'''<br /> <br /> Waterproof each chamber completely by filling it out with aquarium / hot glue, then immediately string the last two acrylic discs onto the wires and glue them to the tubes with acrylic cement. Leave to cure, then reinforce the seal from the outside with another line of acrylic cement. <br /> <br /> <br /> '''Step 5: Spacing''' <br /> <br /> Once the aquarium / hot glue has cured properly, take A3, place it between the two acrylic discs holding the LED and phototransistor, and glue the three parts together with acrylic cement, then leave to dry.<br /> <br /> <br /> '''Step 6: Blocking sunlight with PVC (optional)'''<br /> <br /> Since sunlight includes lots of infrared radiation, it may be necessary to shield your probe. A very simple way of doing this is to take length of PVC tube with a tight-fitting cap, make a hole in the cap for wires, and simply pull the tube + cap over your NIR probe like a lampshade. Making sure the phototransistor is pointing downwards also helps. <br /> <br /> <br /> '''Bonus level: Building the BubbleShakerTM (optional)'''<br /> <br /> Some biological processes form gas (usually C02), which may cause bubbles to form on the surface of the LED and phototransistor and throw off your measurements. To solve this problem, we've created the amazing BubbleShakerTM - a small off-set motor ('buzzer') extracted from an old cell phone, encased in a short piece of acrylic tube plugged with aquarium / hot glue on both ends. <br /> <br /> To build one yourself, the first thing you'll have to do is find an old cell phone somewhere, crack it open, and extract the motor - get as much of the wires as you can, it'll make life easier for you when you have to solder extensions on. Solder about 2 ft / 60cm of additional wire (remember the colours) to both leads. Then take a piece of acrylic tube big enough to fit the motor and about 1/2&quot; / 13mm wire and plug one end with glue. Insert the motor in the tube - make sure fits tightly by wrapping the fixed part in electrical / gaffer tape, taking care not to block the rotor. Plug the other end of the tube carefully with glue, covering the soldered joint for extra strength.<br /> <br /> Attach the BubbleShakerTM to your NIR probe by grinding one side of the tube flat, doing the same to the LED end of the probe, and glueing the two together with acrylic cement. There's a picture of a fully assembled unit [[Media:NIRprobe5.jpg|here]].<br /> <br /> =Interfacing and measuring=<br /> <br /> [[File:NIRprobe6.jpg|200px|thumb|right|Connecting to Arduino]]<br /> <br /> After assembling the probe, you'll need to wire it up to some kind of microcontroller; we've used an Arduino clone called [http://www.ladyada.net/make/boarduino/ BoArduino], and will use that as example, but you can use any type you like. Start out by connecting the 5V and GND pins on the Arduino to the power (+ / red) and ground (- / blue / black) strips on the breadboard. Then wire the LED to 5V and GND across a 150Ω resistor. Now connect the collector lead on the phototransistor to 5V, and the emitter lead to an empty strip on the breadboard, then wire that strip to the A1 pin on the Arduino with a connector, and to ground with a 100Ω resistor. If you've built the bonus version, you'll also need to wire your BubbleShaker to 5V and GND.
