== NoiseLand ==

This page is for collaboratively buying a large parcel of land in the northern half of California, to be collaboratively and collectively owned and cultivated for sustainable living and farming and generating energy by members of Noisebridge and their ilk.

Because Noisebridge-style openness draws many people from different directions and styles, a collectively owned property would have to be large so that people don't chafe on one another. Nobody is suggesting getting a house in the city and letting anyone come crash there, although maybe someone could.

Because of the state of the US Economy, now is a good time to buy land [citation needed]

== Proposed Sharing process of NoiseLand ==

Noisebridge operates on NoiseRule, which is "Be Excellent to Each Other" which is an excellent rule because it is infinitely flexible and adjustable by consensus. Other guidelines will have to be formed in the process of people expressing interest in this idea. There will be other rules at NoiseLand out of necessity, but rather than behavioral rules these will likely be things like Dont Light Big Fires Next To Buildings. Practical things. Black Bear Ranch (a similar land project) and Hellarity House (a collective house in Oakland) are referenced below as resources on where to learn how this stuff actually hashes out.

== Buying process of NoiseLand ==

From a financial and practical sense, buying land will be somewhat similar to Noisebridge renting a building in La Mission. A large amount of cash will have to be paid as a down payment, and then a chunk of cash every month will need to be paid, for 15 or 30 years (or somehow just paying it off, or the previous owner donating the land). Obviously it can't be NoiseLand if it is owned by an individual or small group of individuals, because that would color everything.

After the loan is secured and cash starts flowing, those who supplied portions of the down payment can begin garnishing the income to pay the back ''according to agreements made before the process started.''

There should be a way for people to buy in to this later, after the initial phase, but that might be tricky to set up.

== Proposed uses and purposes of NoiseLand ==

# A place for people from the Noisebridge community to go to get away from the city
# A place for people from the Noisebridge and NoiseLand community to live and work
# Gardening, Farming, Agriculture, Aquaculture, Mushroom growing, Composting, Worm farming
# A base from which to hunt wild animals and pick wild mushrooms
# Somewhere to build giant projects
# A place to experiment with solar energy collection
# Robot Orange Pickers
# Drugs and wild parties in the woods
# Naked all the time
# All the benefits of owning a giant parcel of land but shared responsibility and cost
# Arts and technology retreat or residency, offering people who are doing work we like a place to focus on that work and food to eat while they do it.
# Experiments in building private and communal use housing.
# A place for brewing, fermenting, distilling; a cellar full of homebrew!
# Research and development lab for tech to address problems faced by rural communities
# Refuge from ZOMBIES (or, you know, other societal collapse)
# HELLA bicycling

== Desirable Attributes of parcel to become NoiseLand ==

Land worth buying will have sufficient LEVEL property, sufficient WATER supply (from a well; it is not permitted to draw from a stream) and reasonable ACCESS by road. Hunting is a good way to secure food, and many areas have lots of deer in the winter. Hunting Concessions are covenants signed by property owners permitting people to hunt on their property in exchange for the right to do the same. Farming requires sunlight, good soil (the right mixture of sand, clay, and organic matter) and WATER. Mushrooms grow in wooded areas and nearby forest preserves.

Much land in northern California is at high altitudes. While there is more sunlight at much higher altitudes, it's also much colder and nobody likes that.

It should probably be able to get Internet from the grid, although satellite internet is available but heavily metered and *highly* latent. Depending upon location a rural WISP could be another option. (IMO this is unlikely to already exist on land we are looking at and we might need to pay lots of money to run data cables to our land from Town).

Distance from city - geographic, driving time. Distance from medical services. Growing season. Terrain (hilliness, arability, suitability for proposed uses). Water supply. Availability of services (power, internet, sewage, roads/maintenance). Poison oak, or no?

We should consider the neighbors. Are they going to freak out and object to a bunch of technohippies building yurts? Or, the other way around, are they gun nuts growing giant amounts of pot in underground hydroponics setups?

Price per acre. Collect a few sample prices from different locations to get an idea.

== NoiseBus ==

Owning land means we can get a Bus, used to shuttle people back and forth from the city. It can also have bunks in it so people can sleep during the ride, or when the bus is parked at the land it serves as a few bunks and a room.

Arcosanti is also interesting in that its founder Paolo has grown older, and either senile or less concerned with the opinions of others, and liberally covers the tour/museum portion of the "Arcology" with fliers for women to pose nude for him to paint, you get your very own signed portrait..

In the same way that Realtors escort you through the house-buying process in the city, Realtors will meet you at giant land parcels for sale, walk around the place with you (and they carry GPS) and help you understand things you may not have thought about in those situations. There are many large parcels on the market right now for which a Realtor could arrange a tour.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS WATCH THE LASER BEAM CUTTING YOUR WORK!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS WATCH THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve.

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button

=== Engraving ===

TODO

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Maintenance==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

* TEMP note: some check(s) may be included outside of maintenance so a user can trigger a maintenance notification
* DON'T - let someone who has been trained do it
* how to tell if the lens is dirty (or getting old?)
* how to tell if the mirrors are dirty
** Cleaning the mirrors
*** ethanol solution? isopropanol? - see manual.
*** fabric must be non scratch - see manual.
* Checking and performing mirror alignment
** Safety - remove gratings and any other reflective surfaces before any maintenance that requires disabling the door sensors.
** TEMP note: in restrospect the alignment was a very dangerous situation. mirror paths were not checked before powering on the laser with the door open with many people around. (or maybe nigel is just insanely good at configuring mirrors... still... reddit.com/r/OSHA)
** Tape test - mirrors 1,2,3 and their corresponding exits. Slightly propped laser tube.
** vertical/horizontal alignment by brass dial.
* Checking chiller tank water volume
** Chiller alarm - what does it mean
** Checking tank water volume
** Refilling tank water
* Cleaning the bed and waste drawer (this section probably should be moved to usage)

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives off hydrogen cyanide which can kill you and also may damage the laser optics.
|-
| Fiberglass || Contains complex epoxies which will cause fires, chlorine, and cyanide. Also contains glass which will not cut.
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

=== Monkeybrains Wireless Link ===
We have a point-to-point wireless link to Monkeybrains on the roof, it's a gigabit laser, think of fiber without the physical medium of glass. It is wired into the Monkeybrains NEMA box on the roof, and from there into our own NEMA box in which we house a managed switch. From there the cable enters into the space through the ladder chute in the fox lounge and runs to the rack where it enters the switchboard at port 48. Port 48 is a second redundant run that follows the same path from the rack back to our NEMA box for future projects.

=== SFBroadband / City of SF / Internet Archive ===

We have a wireless point-to-point path up to Twin Peaks that connects up to a city-owned and volunteer-run IP transit network. Currently, we're hitting the dish off of the side and have a pretty terrible connection. For now, this network path is mostly only usable as a backup path.

There is a router in our wireless CPE hardware (st01-noisebridge-sfo) that connects up to the Noisebridge network and terminates as 172.30.0.54 on the "Inside / Internal" network. Set your default route via this IP to try the other path.

==I want to help!==
Noisebridge is run by volunteers, you're welcome to help but should get to know those helping first before touching/hacking the network gear. Try introducing yourself on the [rack mailing list https://www.noisebridge.net/mailman/listinfo/rack].

== Router ==
Biketrailer is our humble router. It is an Ubiquiti Edgerouter 5-port box running EdgeOS, a fork of Vyatta (a Linux-based router distribution). While the router does provide PoE, it is non-standard passive Ubiquiti PoE which you should avoid using.

== Machine Rack ==
The rack sits on the South wall, it's small and up high to discourage people from messing with it or installing things in it. The internet works, please leave the box alone.

===Can I install/setup boxes on Noisebridge's network?===
====Short answer====
'''No.'''

====Long answer====
Noisebridge is here to provide infrastructure for creative projects. We're really good at some things. One thing we suck at is administrating boxes setup on our network. They eat power, internet, the attention span of volunteers, and people who set them up generally are bad at communicating later on down the line when something breaks or a machine magically appears.

Noisebridge network infrastructure policy is as such:
* Critical infrastructure machines (like our access control system): Low power ok!
* Machines for classes that cannot be hosted on the internet: Low power ok!
* Personal machines: NO!
* High power machines: NO!
* Bitcoin minors: NO!
* Torrent boxes: NO!
* Everything else: NO!

If a machine gets setup on the network without first getting an ok from the [https://www.noisebridge.net/mailman/listinfo/rack rack list], it will be unplugged and thrown in the trash. Please don't host your box at Noisebridge. We can't afford it. Thanks for understanding.

===Rack setup===
* Patch panel
* Shitty Fucked Dell 48 port switch
* Pegasus
* Shelf with Biketrailer and POE injectors

|This guy went into the back classroom and took Rayc's wallet out of his backpack. Rayc saw him with the wallet in his hand and the guy tried to say it was his. He then started running towards the door and was tackled by Jake. We made him show us that nothing was in his pockets, and he kept avoiding the big pocket in the front of his jacket. This pocket turned out to have Sasha's smart phone. During the search his crack pipe fell onto the floor and broke into many pieces. We let him go and told him not to come back.

He never hacks anything and makes no secret of the fact that he never will. Jesse Z and Alan asked him to not come back repeatedly (February - March '12).

|Jonathan was asked not to come back, due to allegations of organizing illegal activities from within Noisebridge and theft. A few days later, he had a proxy return to the space a few days later on his behalf to retrieve blankets, etc. that he'd apparently stashed in the darkroom. However, what his proxy took was apparently not the blankets that he wanted, and he shortly thereafter came upstairs and went into the darkroom, himself leaving with items that appeared to be bedsheets. The fabric his associate had taken was found in a heap at the bottom of the elevator and returned to the darkroom. Several days later, Jonathan returned to Noisebridge with his hand shoved in a gym bag, claiming he had a gun. He continued pushing past people to get into the main space, screaming constantly about killing everyone and then himself, and that everyone was to leave, or he would kill them all. He also claimed that the cops were hot on his trail and would arrive at Noisebridge at any moment, and that he intended to provoke a [http://en.wikipedia.org/wiki/Suicide_by_cop suicide-by-cop]. Not sure on whether or not he did have a gun, people were not taking a chance as they filed for the exit. However, Derek, Jedi, Rayc, Ben, stayed behind, calling him on his bullshit. Four people swarmed him as he made a b-line sprint for the fire escape. They wrestled him to the floor and removed his bags away from him. Jedi arm barred and escorted Jonathan down the stairs to the sidewalk, bringing him over to the quickly-amassing phalanx of squad cars. Immediate consensus was that he is not welcome in the space again.

|This person named Ilya was behaving irrationally, and confused his own backpack with Patricks, causing suspicion that he was intending to steal things. He also put on Patricks' clothes and said he thought people were allowed to use whatever items were in the space. He had some small, and not particularly valuable, items that he had pocketed, and had stashed random, not valuable, items in the bathroom. He was unable to explain his behavior to Dr. J and was handed over to police, who did not take him into custody, and he was told not to return to Noisebridge.

He was with his brother Alex who did not do anything sketchy and should not be banned. -jake

|Older guy with longish gray hair, who has often come to Noisebridge with bedding, and has used Noisebridge as a home from time to time. He has been asked to leave, and not come back. He has come back anyway. He has a gate key -- if you see him, demand that he give you the key.

Here is a link to the meeting where Harvey was banned: 
[[Meeting_Notes_2013_09_10#Proposals_discussed_this_week]] 
And here is the relevant quote: 
:"Harvey is no longer allowed in the space. Has admitted to stealing, was caught sleeping in the stairwell on many occassions, returned items that belonged to multiple residents of Noisebridge. Was seen and accounted for by multiple members of Noisebridge to be digging in other people's belongings. Many tools and properties of Noisebridge were found among Harvey's things."

On 24th September 2014 Harvey attacked Mitch while trying to interfere with the contents of the mailbox. "If you see Harvey ever again, call the police. He bit my thumb tonight to get back the piece of mail he was taking from our mailbox."

Kitchen

2014-12-09T08:51:48Z

Jerkey:

[[File:Noisekitchen.jpg|right|thumb|300px|BJ and Zedd welcome you to the Noisekitchen!]]

== THIS PAGE IS OUT OF DATE ==
* the entire kitchen was disassembled during the 2014 reboot, replaced with minimal facilities.
* vandalism preceded the deletion of the kitchen, including destruction by hammer of the (tempered glass) induction stove
* the electric panel of the kitchen had been sabotaged several times before that point
* this direct action was likely in response to a perception that the kitchen supported undesirable use of the space

== Features ==

* refrigerator with freezer
* 2-range electric hotplate
* consumer 2-tub stainless sink
* open storage in closet
* stainless prep counter
* various utensils and supplies
* [[Coffee]]-station with equipment
* food preparation machines
* fermentation station

== Excellence ==

Communal kitchens are difficult to maintain.

Due to the need for sanitation, freshness and the near simultaneous use of tools, communal kitchens are a complex collaborative workplace. Everyone using the kitchen should conciously participate in preventing entropy.

Communication between everyone using the kitchen is essential. Minimalistic direct communication is essential or disfunction, spoiled food, and an unsanitary environment rapidly ensues.

If you are not sure, or are certain you don't know how to use the kitchen, find collaboratores who already have a comprehensive understanding of kitchen excellence.

'''kitchen maxims'''

Use oldest items first. (eg. stock rotation)

Add new to old, never add old to new.

Clean as you go. Leave it cleaner than you found it.

Start with less, add more to taste. (eg. salt, pepper, soy sauce)

Keep drawers and cupboards closed when not in use.

Everything in its place, a place for everything.

Label it. (date, description, project, instructions, ...)

If in doubt, ask.

== Hacking ==

At Noisebridge any use of a resource is called hacking. So using the kitchen for any purpose is hacking. This also means anyone using the kitchen is, at all times, responsible for being excellent.

Kitchen tools belong in the kitchen. Some kitchen tools are expensive and may be difficult to replace. If you need a kitchen tool elsewhere, leave a note on the kitchen white board, and return it as soon as you're done with it.

Larger projects involve resources (tools, ingredients, labor), so the intentional destruction of a project is not being excellent. Make an effort to communicate with the team members working on the project before taking action to remove a work in progress.

Tools for eating and drinking should not leave Noisebridge and should be returned to the kitchen when no longer needed.

The kitchen is a place where bio-hazards appear in a few hours.

If you don't want to kill/sicken the other hackers, ask someone who knows about sanitation, look it up online, or stay out of the kitchen/fridge/dumpster.

If you don't appreciate moldy food or vermin, learn from and help the other food hackers clean.

Communication includes writing labels with as much details needed for coherent communication.

If you want to improve the kitchen, study excellent kitchen design. Since we are hackers, it is ok to keep changing the kitchen, as long as you don't stop until its ready for the other food hackers to return.

If two or more projects are using the kitchen at the same time, work it out using your excellent communication skills.

== algorithm for food hacking ==

begin
communicate with those in and around the kitchen;
discuss your project;
inventory available ingredients, tools, supplies;
plan item or menu;
make shopping list, budget, collect money if needed;
if enough people, split into two groups;
cobegin
{
buying team goes shopping;
cleaning team prepares kitchen;
};
prepare food;
eat, share left overs, safely store uneaten food;
cleaning, sorting, putting things away;
if inclined, write up your experiences, recipes, ideas for the future;..

Pigeon again returned to NB at around 1400, and again was told to leave and not return until tuesday's meeting, and refused to leave and said they is here in protest and said they would only leave if Rayc left. Again cooked a huge amount of food (much of which they carried out in a dirty bucket at around 1530) and got argumentative with both myself and Rayc when asked to leave. They didn't leave until after 1600, about a half hour after Rayc left.

==Guidelines==
(Here's some perspective excerpted from the Noisebridge mailing list ...)

https://www.noisebridge.net/pipermail/noisebridge-discuss/2013-March/034846.html
<pre>
[...] one of the reasons why the Noisebridge tradition has emerged
over the last few years of asking people to leave and come back at
meeting is to defuse immediate situations. It doesn't mean anything more
than some matter has arisen that the people involved feel uncomfortable
handling on their own, and would rather discuss it with the wider
community.

It's not intended as a punishment. Indeed, if one feels outraged that
one will have to spend a maximum of seven days not at Noisebridge, I do
rather think one is probably making Noisebridge too much of your life,
and need a break anyway.

I also strongly believe the following points represent a consensus
position at this point, although it isn't the sort of thing that we put
through official consensus, it's definitely something that fits with
what most of us do when we're doacratically handling these situations.

1. If you're in an argument with somebody that seems irresolvable and
looks like it's escalating, you or they should ask the other to leave
and come back to meeting. It's okay for both sides to do that, because
that gets the confrontation out of the space, and gives time for people
to calm down.

2. It's considered excellent to leave and come to the meeting. It counts
in your favor.

3. Not leaving isn't excellent, because at that point at least one
person is stuck in an immediately intractable problem.

4. Neither is it excellent to leave, and coming back before meeting. Nor
should thou take over an hour leaving and then hover around the gate,
very slowly picking up your laptop pieces, like with Junior that last
time.

5. It's almost certainly not excellent, incidentally, to try and game
this by just repeatedly asking people to leave and come back at the next
meeting, and then like two minutes after the meeting, ask them to leave
and come back to the next meeting, etc. There are many other exploits like
this that you can think of. Almost all of them fall under another
widely-held hackerspace axiom, "don't be a dick", and won't get you any
credit when you come to the meeting with a big grin on your face.
Indeed, you may find that the person who did the asking to leave will be
in far bigger disgrace than the person who left. This happens. A lot.

5. If you feel ABSOLUTELY outraged about being kicked out, come back at
meeting, and almost certainly other people will feel ABSOLUTELY OUTRAGED
on your behalf, or perhaps roll their eyes at what happened. It is a
good way to see how the rest of the community feels. It is very unlikely
that if you are asked to leave for a dumb reason that the rest of the
meeting will sympathise with the person telling you to leave. If they
do, perhaps your OUTRAGE was misplaced.

6. And yes you are part of a community, and your big "nobody tells *me*
what to do" isn't actually the anarchism we practice here. Otherwise you
could just turn the place into a satanic ice cream parlor and everyone
would be like woooo anarchy, which they would not. Well, maybe at first,
but then they would be like why are these arduinos vanilla flavored and
melting, and the crying would begin.

I am a Member of Noisebridge. I have a page where I keep PGP-signed statements of endorsement of people applying to be Associate Members or Members of noisebridge, but I have started endorsing people with a simple link to my user page out of laziness. If you want to discuss or confirm my endorsement of someone please contact me by email or on irc right away.

I have been coming to noisebridge since 83C when the silver microwave was dragged in off the street. My friend repaired it. Now it's broken again and it might need a new magnetron. <S>I might turn it into a large vacuum-tube amplifier.</S> It was then sabotaged by Jesse Z. to discourage use of the kitchen, and then it was thrown away.

There are some posts by me on the noisebridge-discuss list.
 
I started several wiki pages, including Noise-Bot (MCHawking the robot wheelchair), NoiseLand (let's buy a farm together), and WeKnow (the collective knowledge of the noisebridge community in question and answer form).
 
At Noisebridge, I know where things are, and try to know who's around.
 
I made a giant robot, Noise-Bot, and I made a microscope camera with Mike which outputs to composite video, so everyone can see the tiny solder joints you're doing (and so can you)

User:Uriah

2013-11-15T05:59:36Z

Jerkey:

My name's Uriah or Demmy on IRC.

I've been coming to the space for a bit over a year and a half now with irregular frequency. I started by coming to Circuit Hacking Mondays and then from there came to a bunch of 5MoF and for awhile took it upon myself to be the person who tried to keep the kitchen clean when I was around.

I'm attending the introductory PyClass and the advanced PyClass. I'm also taking the Front-end Web Development class, too.

I am a recent transplant to the Bay from Chicago. My background is in writing, activism and social practice art. I write for the Ella Baker Center in Oakland and am greatly invested in activism surrounding civil rights, racial and gender inequality, et cetera. I do some personal chef work as a part of my activism and art practice dealing with inequalities surrounding access to food and the ways in which that is systemically decided. I'm super interested in the ways in which food helps shape culture and vice versa.

I'm currently teaching myself Python and computer science as well as front-end development. I'm looking for opportunities involving that. Looking to network, make things that help people and generally make ~cool thangs~.

I am a Junior Architect and Maker. I believe that Noisebridge's mission to provide infrastructure for technical/creative projects to the local community is important, and one that I can proudly support. I am happy that Noisebridge exists and thankful for the opportunity to contribute to, and benefit from, it.

This is my most recent project in the space.

Jerkey: /* Associate Membership Sponsors */

I am a Junior Architect and Maker. I believe that Noisebridge's mission to provide infrastructure for technical/creative projects to the local community is important, and one that I can proudly support. I am happy that Noisebridge exists and thankful for the opportunity to contribute to, and benefit from, it.

This is my most recent project in the space.

"oh hai, I missed the meeting from heartfelt sickness, but here is your

I have also paid Noisebridge's business insurance for this year, which
came to $1285.20."

= Consensus items =

== [[ Consensus Items History | Proposals from last week ]] ==
*'''Proposal regarding the suspension of members adjusted and consensed'''

Agreed that consensus minus `n` is adequate to suspend a member of Noisebridge. Wording of proposal has been amended to read:

"No member shall be entitled to full participation in the consensus process around a proposal to suspend that person's membership of Noisebridge. Suspension is defined as: if a member has been suspended, they shall no longer be considered a member of Noisebridge for any purpose, including but not limited to, full participation in the consensus process."

Consensed.

*'''Procedures regarding associate members, left over from last meeting, cleaned up and consensed'''

The following procedures will be cleaned up and added to the Consensus Items History and the How to become a Associate Member pages.

Proposal to create an Associate Member role and limit access to Noisebridge 24/7 to Member, Associate Member and those hosted by M and AM

Items discusssed:

''Who can sponsor whom?''

Monad proposes that 4 signatures are still needed, and at least two of those be "Capital-M" members, but the other signatures may come from associate members. It is proposed that any 4 signatures be sufficient to reduce some of the complexity of the process. Some possible abuses are brought up but after discussing them it is agreed that abuses will be dealt with as they come. In general, abusers of the associate membership process are not people who should be here, and can be dealt with as such. Any 4 signitures from Ms or AMs is deemed sufficient for AM.

''Privacy of members? Pseudonym?''

Associate members may use pseudonyms, and protect their identity as needed.

''Can email or some other electronic method be acceptable for associate membership?''

Yes, and see below.

''Proposal to make associate membership digital-only, fed by the wiki page.''

In line with this, it is suggested that the AM process go completely paperless. After some discussion of the details it is worked out that applying for associate membership is done online, through the wiki, no other means. Prospective AMs create a user page (pseudonym or otherwise) and sponsors endorse you by editing your wiki page and professing their endorsement.

''What form can that take?''

Sponsor ship can be a simple wiki edit on the sponsoree's page saying that the sponsor approves of the person.

== [[ Current Consensus Items | Proposals for next week ]] ==

*'''Proposal to require a minimum number of members present for consensus - Blocked'''

Brief discussion. No proxy means to adjust/modify the proposal. Blocked as paralyzing to the consensus process.

*'''Proposal to revoke the members only consensus items - Blocked '''

It is argued that the recent members only proposal is exclusive and ridiculous; it suppresses people's voice in the space. This is responded to with various comments. Leaving things as they are is not a better way to improve Noisebridge, if someone has designed a better proposal/solution, please propose it. Work is being done in good faith and the Associate Membership process is being improved to be more accessible and better documented for new Noisebridge users. It is argued that these new procedures will in time make Noisebridge safer and more inclusive of people and projects that should be happening and exclude people and projects that prevent them. As hackers, we should be willing to fix a broken system, or at least try. Associate member sponsorship is given to just about anyone that requests it, with the side effect that the prospective member has now met more people in the community. This policy, while understandable in Noisebridge's context, should not be called some sort of "radical inclusion".

Blocked as premature at this point.

*'''Proposal to improve door security discussed, with proposal to be further detailed for next week'''

Intention is to ensure that Noisebridge be secure when not occupied. JC will flesh out proposal further.

*'''Proposal that the list of members and associate members is not a secret, and that the secretary keep the wiki posting accurate and non vandalized."'''

With the current changes in membership procedures, it is proposed that the list of existing members be made more available.

NoiseLand

2013-08-28T00:39:52Z

Jerkey: /* Resources and further study: */

[[File:Robot_farm.jpg|right]]

== NoiseLand ==

This page is for collaboratively buying a large parcel of land in the northern half of California, to be collaboratively and collectively owned and cultivated for sustainable living and farming and generating energy by members of Noisebridge and their ilk.

Because Noisebridge-style openness draws many people from different directions and styles, a collectively owned property would have to be large so that people don't chafe on one another. Nobody is suggesting getting a house in the city and letting anyone come crash there, although maybe someone could.

Because of the state of the US Economy, now is a good time to buy land [citation needed]

== People interested in NoiseLand ==

* Jake (spaz) - member-level funding and helping craft charter/constitution/plutarchy plus looking for land
* Lizzard - fulfill weekend warrior fantasies of building houses and walls, vegetable gardening, giant compost piles, driving tiny bulldozer. Proximity to SF is important
* Danny O - ?
* Rachel H - mouthy
* Sean C - ?
* Alex G - ?
* Mitch - offering advice and experience
* Olya K - ?
* Frantisek Algoldor Apfelbeck - I want to get involved especially in the food&beverage hacking, plus other biotech applications
* Ben M - ?
* Rachel M [[User:Rachel|Rachel]] 01:37, 27 November 2011 (UTC)
* Greg R - I have some knowledge of earthen/cob building technique and woodworking abilities with hand tools (such as the axe). I'm really excited to start building and am in search of a place to help design and build a sustainable community.
* Jenny R - anthropologista extraordinaire. let's build a world!
* Evan M
* You???

== Proposed Sharing process of NoiseLand ==

Noisebridge operates on NoiseRule, which is "Be Excellent to Each Other" which is an excellent rule because it is infinitely flexible and adjustable by consensus. Other guidelines will have to be formed in the process of people expressing interest in this idea. There will be other rules at NoiseLand out of necessity, but rather than behavioral rules these will likely be things like Dont Light Big Fires Next To Buildings. Practical things. Black Bear Ranch (a similar land project) and Hellarity House (a collective house in Oakland) are referenced below as resources on where to learn how this stuff actually hashes out.

== Buying process of NoiseLand ==

From a financial and practical sense, buying land will be somewhat similar to Noisebridge renting a building in La Mission. A large amount of cash will have to be paid as a down payment, and then a chunk of cash every month will need to be paid, for 15 or 30 years (or somehow just paying it off, or the previous owner donating the land). Obviously it can't be NoiseLand if it is owned by an individual or small group of individuals, because that would color everything.

After the loan is secured and cash starts flowing, those who supplied portions of the down payment can begin garnishing the income to pay the back ''according to agreements made before the process started.''

There should be a way for people to buy in to this later, after the initial phase, but that might be tricky to set up.

== Proposed uses and purposes of NoiseLand ==

# A place for people from the Noisebridge community to go to get away from the city
# A place for people from the Noisebridge and NoiseLand community to live and work
# Gardening, Farming, Agriculture, Aquaculture, Mushroom growing, Composting, Worm farming
# A base from which to hunt wild animals and pick wild mushrooms
# Somewhere to build giant projects
# A place to experiment with solar energy collection
# Robot Orange Pickers
# Drugs and wild parties in the woods
# Naked all the time
# All the benefits of owning a giant parcel of land but shared responsibility and cost
# Arts and technology retreat or residency, offering people who are doing work we like a place to focus on that work and food to eat while they do it.
# Experiments in building private and communal use housing.
# A place for brewing, fermenting, distilling; a cellar full of homebrew!
# Research and development lab for tech to address problems faced by rural communities
# Refuge from ZOMBIES (or, you know, other societal collapse)
# HELLA bicycling

== Desirable Attributes of parcel to become NoiseLand ==

Land worth buying will have sufficient LEVEL property, sufficient WATER supply (from a well; it is not permitted to draw from a stream) and reasonable ACCESS by road. Hunting is a good way to secure food, and many areas have lots of deer in the winter. Hunting Concessions are covenants signed by property owners permitting people to hunt on their property in exchange for the right to do the same. Farming requires sunlight, good soil (the right mixture of sand, clay, and organic matter) and WATER. Mushrooms grow in wooded areas and nearby forest preserves.

Much land in northern California is at high altitudes. While there is more sunlight at much higher altitudes, it's also much colder and nobody likes that.

It should probably be able to get Internet from the grid, although satellite internet is available but heavily metered and *highly* latent. Depending upon location a rural WISP could be another option. (IMO this is unlikely to already exist on land we are looking at and we might need to pay lots of money to run data cables to our land from Town).

Distance from city - geographic, driving time. Distance from medical services. Growing season. Terrain (hilliness, arability, suitability for proposed uses). Water supply. Availability of services (power, internet, sewage, roads/maintenance). Poison oak, or no?

We should consider the neighbors. Are they going to freak out and object to a bunch of technohippies building yurts? Or, the other way around, are they gun nuts growing giant amounts of pot in underground hydroponics setups?

Price per acre. Collect a few sample prices from different locations to get an idea.

== Location ==
Add possible locations you recommend, whether areas or parcels for sale.

Owning land means we can get a Bus, used to shuttle people back and forth from the city. It can also have bunks in it so people can sleep during the ride, or when the bus is parked at the land it serves as a few bunks and a room.

Arcosanti is also interesting in that its founder Paolo has grown older, and either senile or less concerned with the opinions of others, and liberally covers the tour/museum portion of the "Arcology" with fliers for women to pose nude for him to paint, you get your very own signed portrait..

In the same way that Realtors escort you through the house-buying process in the city, Realtors will meet you at giant land parcels for sale, walk around the place with you (and they carry GPS) and help you understand things you may not have thought about in those situations. There are many large parcels on the market right now for which a Realtor could arrange a tour.

The payphone is connected to Minotaur by a long blue CAT5 cable which runs up the stairwell and across the ceiling. This cable carries two-way serial data and 12VDC to power the arduino in the payphone. When a user enters a valid code followed by <tt>#</tt>, <tt>baron</tt> uses the Noisebridge [[API]] to open the [[gate]], while the payphone LED flashes blue, and a "happy" sound is heard. If an incorrect code is entered, or enough time passes between button presses, the payphone LED flashes red, and a "sad" sound is heard. If the gate API throws an error, the light turns red and a sad noise is played three times.

the pinout of the RJ45 to DB9 serial adaptor used on the minotaur end of the cable is standard, except that pin 7 of the RJ45 socket does not connect to the DB9F socket, but instead exits the connector in a wire headed to minotaur's power supply as +12v. Pins 4 and 5 of the RJ45 (which goes to 5 of the DB9F) is ground, which also connects to a wire headed to minotaur's power supply, to ground.

== Minotaur ==

* The keypad hardware hooked up to Minotaur at /dev/ttyS3 https://www.noisebridge.net/pipermail/noisebridge-discuss/2012-February/028485.html
* The hardware above actually runs on 12V (not 5V) and the Arduino code in the above post is outdated.
* Updated Arduino code for the doorkeypad hardware can be found here: https://github.com/jerkey/doorkeypad
* <tt>/usr/local/share/baron/noisebridge-baron/baron.py</tt> - baron script, takes arguments --port=/dev/whatever and --codefile=/var/blablabla/codes
* <tt>/etc/init/baron.conf</tt> - jesse's init script
* <tt>/usr/local/share/baron/codes.txt</tt> - codes file, any line starting with a 4-7 digit number (ignoring whitespace) is interpreted as a valid code, # is used for comments

Please label your codes so that others know who to contact and when to expire them.

= Future Plans =

To improve, the code, please issue a pull request against https://github.com/noisebridge/noisebridge-baron. It you improve the hardware, please document the new state here, and make note of your changes in the [[changelog]]. If you would like to make changes to '''how''' the system works, as opposed to just how elegantly it's implemented, please talk to the people named above.

The software has to be gone over to make sure it can be run in multiple instances, because someday we will put a second keypad at the top of the stairs, so that buzzing someone in requires a code.

We should also create a web-accessible door-opener page which requires a code (from the same database) so that, in case we decide to end the uncredentialed door opener page, we will have a code-authorized alternative already in place.

==Keycode Generation==

There can be any number of plugins that generate keycodes, as long as they are non-destructively copied to the codes file on Minotaur.

== Todo ==

* Add a "bad" codes list, to block codes from being reused.
* Add the ability to expire codes - maybe a comment in the codes.txt file?
* Add another keypad at the top of the stairs, so letting someone in requires a code
* Create a web interface, so buzzing the door from laptop requires a code

= 950 MHz UHF RFID system =

This RFID reader is installed near the entry door of Noisebridge (at the top of the stairs). If it can be made to work properly, we can put RFID tags in any items we want (private or public) and program our computer systems to react if and when those items go near or through the door (or elevator room). This could be useful in deterring or preventing theft, so that Noisebridge CAN Have Nice Things.

current state of things: the reader works, we talk to it through serial, and it detects tags, but all the tags we have result in the same line of text from the reader. We need to figure out what command to send to the reader to get it to tell us the full data of the tags, or at least their unique serial number. We have over 100 tags, but they aren't readable until a piece of wire is soldered onto them as an antenna, which can be tailor made for the article they are being fixed onto. The PDF for the tags we have is linked to below, uploaded to the wiki as rfid.pdf If you want to help with this project, contact me. -jake

* We got this reader: SAMSys MP9320 2.8
Various files related to this device:
http://techsupweb.satoamerica.com/public/06_RFID/Software/RF%20Command%20Suite/

the protocol the reader talks is detailed at:
[http://www.sirit.com/Tech_Support_Downloads/CHUMP_Prot_Ref_Gd_v7.0%5B1%5D.pdf CHUMP Protocol Reference Guide v7.0]

[http://itech.fgcu.edu/faculty/zalewski/projects/files/RFID_Zabala_final2.pdf The MP9320 cannot be made to work on ethernet, even though it has a port.]

The reader is connected to Minotaur through a USB to Serial adaptor which comes up as /dev/ttyUSB2 (this time) BUT
 
you should talk to it through its reliable pathname which is: 
<tt>/dev/serial/by-path/pci-0000:02:02.3-usb-0:1.1.4:1.0-port0</tt>
 
try the following command (as root on minotaur) 
<tt># screen /dev/serial/by-path/pci-0000:02:02.3-usb-0:1.1.4:1.0-port0 57600</tt> 
(press control-A and then k to "kill" or exit screen when you're done)

the reader is now configured and it works. when it detects a tag, the windows software tells you
 
Tag ID,Tag Name,Tag Type, Total Reads, Rate, Antenna, Date/Time
 
3005FB63AC1F3841EC880467,,EPC1G2,1648,0.0,0,1/21/2013 11:04:06 PM
 
 
this is what the serial data looks like, 57600 baud: (it repeats constantly while the tag is nearby)
 
{Rd,d:3005FB63AC1F3841EC880467,t:EPC1G2,e:28;14
 
 
this reader has four antenna ports. The windows software seems to tell you which antenna the tag was seen on, but we will need to find that information in the serial data, which should be easy. The reason this matters is because we will end up having antennas in different locations (door at the top of the stairs, elevator room door, bottom of the steps) and we will want to react differently depending on where a tag is detected.

[http://spaz.org/~jake/r/rfid-SL3S1202AC0.zip zipfile containing many PDFs relating to these RFID tags including the NXP app notes]

these tags do not have an antenna - they are a grain of sand in the middle of a 3mm x 9mm piece of plastic. On either side of the grain of sand is a copper contact that you can solder to if you're careful. don't melt the plastic backing! the whole thing will probably stick to whatever it was resting on when you soldered it, so prepare. Make your antenna (a loop of wire probably, we are trying to figure out what works best) and solder it to the two contacts and then protect the thing with some hard (hitemp) hotglue or epoxy or something.

== Some General Commands==
<pre>
Show reader and software version info:

}:01,Rv,f:0!

Show config:

}Cr!

Quiet a given tag from the output:

}Ht,d:[ID]!

Read any tag in field

}Ra,a:[block],s:[offset](,l:[length])!

</pre>

== Setting Tag EPCs ==
[[Image:Rfidmem.jpg|thumb|right|Memory map for cheap NXP RFID tags. We need to change the EPC in bank 01]]

GEN2 (aka ISO 18000-6C) tags contain a unique, factory set tag ID (TID) and a user configurable EPC. Per the datasheet the EPC is the same for all our tags until configured otherwise

<pre>
The ICs are delivered by NXP with a default 96 bit EPC number:

UCODE G2XM: 3005 FB63 AC1F 3681 EC88 0468

UCODE G2XL: 3005 FB63 AC1F 3841 EC88 0467
</pre>

Our reader appears to display some form of the EPC when a tag is in range. It's possible the query tags in the field for TID, but I'm not sure if we can display TID by default when a tag is in range (the EPC appears to be read by default) -- but we can reprogram the EPC to some arbitrary value!

* [http://www.sirit.com/Tech_Support_Downloads/CHUMP_Prot_Ref_Gd_v7.0 Chump Reference Guide]
* [http://www.sirit.com/Tech_Support_Downloads/MP9311_Users_Guide_V2.0.pdf User Guide] - Though for a different model, pg 52-56 provide some good examples on writing to gen2 tags
* [https://github.com/danasf/noise-rfid code] - script to read/write to a serial port, to filter out duplicate output]

Some example commands (note: wa command will write to any unlocked tag in the field):
<pre>
To write an EPC ID value of 332233445566778899aabbcc onto a tag with the Protocol Control field set for a 96 bit tag, enter:

}wa,a:01,s:02,b:332233445566778899aabbcc!

To add the length field, enter:

}wa,a:01,s:02,b:332233445566778899aabbcc,l:6!

To request a read/verify cycle following the write operation, enter:

}wa,a:01,s:02,b:332233445566778899aabbcc,l:6,f:1!

In order to write an EPC ID to a blank tag, the Protocol Control bits must also be
set. This can be accomplished in a single write command since the Protocol Control
bits are contained in the same memory bank as the EPC ID. Following the previous
example, the command would include setting the Protocol Control to 3000 as follows:

}wa,a:01,s:01,b:3000332233445566778899aabbcc!
</pre>

=== Changing Registers ===
This reader has a number of config registers we can modify. Use the following CHUMP command to read the current registers:

<pre>
}Cr!
</pre>

To make changes to a setting you'll need to generate a hex value for the 32 bit register. Refer to section 4 and 5 in the CHUMP reference guide for bit positions and usage. This [http://calc.50x.eu/|nifty calculator] can make the process easier. Of particular interest is P2I, the GEN2 identification layer control register, which maybe will allow us to change the default memory read location (from EPC to TID).

When you're done you can write your register as follows:

<pre>
}Cw,d:REGISTER,b:10100!
</pre>

add ",f:1" to save to NVM, otherwise the setting will revert upon restart.

== Hardware ==

M.C. Hawking the Wheelchair Robot, AKA Noise-Bot, uses an electric wheelchair (Action Arrow Storm Series). This is a mid-sized electric wheelchair which can be dis-assembled without tools and transported in a car, which is how it got to noisebridge. It uses two 12-volt lead-acid batteries such as car batteries. The batteries are wired in series for 24 volts, and it is necessary that they are matched so that one doesn't wear-out the other during use and charging.

At this time (April 2011) the batteries have been replaced with full-size gel-cells with decent capacity.

An Arduino has been added to monitor battery voltage, and has the ability to turn off power to everything except itself and the wheelchair joystick (but that is coming soon). If the battery voltage drops below 18 volts for 25 consecutive seconds, the Arduino will turn off the computer until the batteries go above 24 volts - when the charger is hooked up.
There is also a DB25F connector wired to the Arduino so that the wheelchair's joystick interface board can plug into the Arduino instead of the PC parallel port. It is wired so that the four directions connect to four PWM-capable outputs of the Arduino.

The Arduino program is written to watch for direction commands sent by the computer through the serial interface as a two-byte sequence. Case-sensitive F B L R for the four directions, followed by a byte corresponding to the magnitude of thrust in that direction. The left-right axis is independant of the forward-backward axis. To stop, send SS (Capital S twice). All direction commands expire after one second and so must be re-sent often enough to prevent auto-cancellation. All this is moot if you have not sent a "Pz" lately, which is the command to activate the wheelchair-power-enable relay. It must be a capital-P followed by a lowercase z. This command expires after 2000 milliseconds, so your software has to send it over and over or the power relay will click off and you won't go anywhere. Read the latest version of robotpower?.pde.

'''The arduino's FTDI chip is a USB serial port, accessed at /dev/arduino1 OR at /dev/ttyUSB0'''
This was set in some udev config file, and it corresponds to this arduino's FTDI chip serial number.

You can hopefully find the latest version of the robotpower arduino program in the home directory of mchawking. This program is where things like low battery shutoff voltage, and the timeout period for motion commands, are set.
[http://spaz.org/~jake/robot-emc/robotpower8.pde | Arduino program as of September 2011]

Note that the Arduino program can't see the arduino's serial port (/dev/ttyUSB0) unless it is run by root.

[http://spaz.org/~jake/robot-emc/IMG_0602.JPG | Robot Arduino without DB25 yet]

The battery charger consists of a voltage-regulated power-supply connected to the battery pack through a large Diode. The robot has an AC power plug mounted on a bracket in between the front wheels and facing foward. There is an electrical outlet mounted on a wooden bracket at the appropriate height for electrical docking. There is a USB camera (with built-in LED lights) on the robot which allows for visual alignment of the electrical connection. In the future, the robot will be able to plug itself in by driving up to its special socket, so that the onboard computer does not have to be shut down or manually plugged into mains AC to avoid draining the batteries.

There is a computer (separate from the wheelchair controller which technically has a computer in it) which is in a stamped aluminum case just like the media server. It uses a model [http://spaz.org/~jake/robot-emc/MS-9642-Manual.pdf | MS-9642] mini-motherboard and a [http://www.mini-box.com/M3-ATX-DC-DC-ATX-Automotive-Computer-car-PC-Power-Supply?sc=8&category=981 | Mini-Box M3-ATX power supply]

The box is currently powered by a custom voltage regulator made by jake. It accepts up to 40 or so volts, but will never deliver more than 23 to the M3-ATX which is hard-limited to 25 volts. If the voltage is at or below 23 volts, its FETs are in full conduction and there is zero dropout. Once on, the M3-ATX will keep the computer running unless voltage goes below 7 volts, at which point the 24-volt battery array of the wheelchair is being seriously damaged.

The voltage regulator's input plugs into a connector coming from the wheelchair controller's blue power connector, which is connected through a T-splitter going to the charger and to the batteries. '''This is where the voltage regulator gets disconnected when the computer is being worked on, so there are no shocking "surprises".''' The output of the voltage regulator goes to three tab terminals and a cord to the LCD monitor, to provide the computer's power supply with constant voltage, ground, and a second positive terminal for the unused on/off switch function of the power supply. Read up on the M3-ATX linked above.

A circuitboard zip-tied to the arm-rest interfaces the parallel port of the computer to the joystick. This circuit uses transistors to trick the wheelchair controlbox into thinking that the joystick is somewhere other than at-rest in the center. Of the eight bits of the parallel port, two make the chair go forward, two to the right, two to the left, and two backwards. For each direction, there is one bit causing low speed and another causing medium speed. Both bits cause full speed. This "speed" is separate from the speed control function of the two switches (one of which also controls on/off). A steady-state on the parallel port is not ignored by the circuit, so a computer crash will cause the chair to go out of control. In the future, the Arduino will connect instead of the PC parallel port, and it contains software to "expire" any direction command not refreshed by the PC.

Sensors have been installed on the motor which allow the computer to track movement and speed. An old ball-mouse has been disassembled and its sensors mounted on wires, and these sensors were placed at the open end of the drive motors. An optical interruptor is attached to the end of the motors' driveshafts, so the "mouse" reports movement on the x and y axes of the mouse when the left and right wheelmotors turn. The "mouse" is DB9 serial, and is seen by the computer as a serial accessory rather than as an actual Human Interface Device to move a mouse cursor (this would not be the case if a USB serial adaptor were used). The serial port corresponding to this "mouse" (which uses standard serial mouse protocol to report "movement") is '''/dev/odometry''' as set in udev config files.

An LCD monitor has been mounted permanently as the seatback. '''The ON/OFF switch for the monitor and its built-in amplified speaker-system is a pushbutton switch on the left (as you look at it) "shoulder" of the robot. Sometimes the speakers enter a feedback loop and power to the screen should be shut off to cease this irritation.''' The monitor is an [[Inexio]] touchscreen but we have not implemented the touchscreen function yet.

A robot arm made of mostly aluminum and animated by air-cylinders was fitted to the robot, but few electronic valves and no air compressor or tank have been acquired. Someone will have to invest time and energy to get the arm to do more than make the thing look more menacing. As of 11/15/2010 the arm was removed to make the robot more wieldy/less unwieldy.

Several electrically-operated linear actuators were acquired and would make great "muscles" for a large robot arm made from scratch. The air-powered arm is not a good match though, so a new arm should be made with those linear actuators causing magnified movement at joints such as elbows and a shoulder.

== Software ==

The PC is running a stock Ubuntu with PyParallel being used by the controller program to access the parallel port. All the software from the home directory as of 11/15/'''2010''' is here:

http://spaz.org/~jake/robot-emc/

As of April 2011 the software has been moved around and a lot of projects are in the works. Contact Lilia Kai at gmail or Jake at spaz if you want to get involved in reading or writing programming for the robot.

As of September 2011 the latest motor-control firmware for the Arduino is here:

== Network Connection ==
The embedded PC is using a '''Cisco Aironet 1220B''' which was hardware-hacked by Jake to accept power from the ATX power supply of the computer. This consists of 3.3V and 5.0V which, plus ground, come into it with a custom three-terminal connector. A '''Generic Realtek USB 802.11b''' interface, which is sub-excellent, is also available in case the Cisco is not working or if the robot needs to access an 802.11b network.

The Cisco Aironet 1220B named wbr2 on the wheelchair associates to a matching Cisco 1220B named wbr1 at 2169 Mission. They use 802.11a to communicate on a dedicated channel. They use the default username and password for that platform. The embedded PC uses its ethernet port '''eth1''' to talk to the Noisebridge network via a connection to wbr2's ethernet port.

The embedded PC is configured from '''/etc/networks/interfaces''' Also, Network-Manager which is the gui-compatible 21st century newschool network configuration system is been pushed to the side, possibly for good. The embedded PC is now configured to find the wireless network called '''noisebridge''' and take the internal IP below.

=== Noisebridge internal IP address ===

The robot's USB wireless interface has claimed an IP on the internal network of

172.30.0.50

=== Access from outside 2169 Mission ===

Configuration of the firewall is done (thanks Jof), so that connections to the machine can be initiated from the outside world. This is important if people are expected to log in and drive it around from Germany or Singapore.

=== DNS entry ===

In the future someone will assign that IP address a '''DNS entry''' like

robot.noisebridge.net

== Local Operation ==

The electric wheelchairs' controller brain will not allow movement unless the joystick is at rest for a second when power is switched on. If the computer has not initialized the parallel port to the "stop" bitpattern, and the switch is flipped on, the green LED will flash endlessly because it thinks you are leaning on the joystick and don't intend to do so.

The drive-wheels have clutches which can be disengaged from their motors (and brakes) by pressing a button and rotating a collar until it can be pulled outwards. When the clutches are disengaged, the robot can be pushed around like a shopping cart, and the motors can be activated without actually causing movement. Sometimes the robot must be pushed forward or backward in order to engage or disengage the wheel clutches, because they are like gears and only fit together in some positions.

'''Disengaging the clutches before testing movement software is highly recommended, as you will be able to see the motors trying to run you over without the robot being able to actually do it.''' This is like taking the laser off of Johnny Five before sending him to the lightning-prone recharging booth.

== Operation Outside 2169 Mission ==

The robot has been successfully field tested at a local convention. The procedure to convert the robot for operation outside Noisebridge is:

* Connect to the Cisco Aironet 1220B wireless device behind the monitor with an RS232 to RJ45 cable, wired to the Cisco pinout, and set your computer's terminal to the appropriate baud rate and settings. The following instructions assume familiarity with the programming of Cisco wireless devices through a serial connection.
* Log into wbr2 and say "enable". Enter the password.
* Say "copy nvram:outside-config nvram:startup-config", then "reload".
* Once wbr2 has restarted, there will be an 802.11a wireless network named "robots" you can associate to.
* Secure any loose items on the robot. Put a garbage bag or something over the rest to protect connectors from splashes.
* Inflate the tires and check for leaks.
* Charge the robot's batteries fully, just in case.
* Power down the robot and move it to wherever it needs to go. Follow the instructions under "local control" if you'll be driving.
* Once at the destination, if your computer has 802.11a (5.8GHz) wifi (many Macbook Pros have this), you can log into 172.30.0.50 over the "robots" wireless network to do whatever you need to do.

When ready to return:
* Charge the robots batteries fully.
* Put a splash guard on the robot's exposed bits again.
* Secure any loose items on the robot.
* Inflate the tires and check for leaks.
* Power down the robot and move it back to 2169. Do not do this in a hurry. Take note of public transit instructions for wheelchair users BEFORE arriving at the station or stop.
* Once back at 2169, clean the robot.
* Log into wbr2 and say "enable". Enter the password.
* Say "copy nvram:noisebridge-config nvram:startup-config", then "reload".

'''Projects:'''

There will be projects from noisebridge at the faire this year.

* high above the crowd, the space over the booth will be festooned with tooth pick sculptures by [[monad]
* the space will also be decorated with light.
* a sign will rise up from behind, announcing the presence of Nosebridge to all.
* miloh will be bringing a project as of yet still under wraps
* 3D head scanning for 3D printers, etc. If we had a big screen TV, my lappy can output HDMI. Headscans look cool on TV. My printer is currently broken, so can we borrow a Type-A?

====Other Items to Bring====
* NB flyers
* NB stickers
* NB t-shirts?
* a colloage of photos of noisebridge?
* the [[RoboConfessional]] Especially set up to hear allow the automat confession of sins from faire goers. Also serving as infoshopbot.

= 950 MHz UHF RFID system =

current state of things: the reader works, we talk to it through serial, and it detects tags, but all the tags we have result in the same line of text from the reader. We need to figure out what command to send to the reader to get it to tell us the full data of the tags, or at least their unique serial number. We have over 100 tags, but they aren't readable until a piece of wire is soldered onto them as an antenna, which can be tailor made for the article they are being fixed onto. The PDF for the tags we have is linked to below, uploaded to the wiki as rfid.pdf If you want to help with this project, contact me. -jake

* We got this reader: SAMSys MP9320 2.8
Various files related to this device:

[http://itech.fgcu.edu/faculty/zalewski/projects/files/RFID_Zabala_final2.pdf The MP9320 cannot be made to work on ethernet, even though it has a port.]

The reader is connected to Minotaur through a USB to Serial adaptor which comes up as /dev/ttyUSB1
 
you should talk to it through its reliable pathname which is: 
<tt>/dev/serial/by-id/usb-Keyspan__a_division_of_InnoSys_Inc._Keyspan_USA-19H-if00-port0</tt>
 
try the following command (as root on minotaur) 
<tt># screen /dev/serial/by-id/usb-Keyspan__a_division_of_InnoSys_Inc._Keyspan_USA-19H-if00-port0 57600</tt> 
(press control-A and then k to "kill" or exit screen when you're done)

the reader is now configured and it works. when it detects a tag, the windows software tells you
 
Tag ID,Tag Name,Tag Type, Total Reads, Rate, Antenna, Date/Time

this reader has four antenna ports. The windows software seems to tell you which antenna the tag was seen on, but we will need to find that information in the serial data, which should be easy. The reason this matters is because we will end up having antennas in different locations (door at the top of the stairs, elevator room door, bottom of the steps) and we will want to react differently depending on where a tag is detected.

[http://spaz.org/~jake/r/rfid-SL3S1202AC0.zip zipfile containing many PDFs relating to these RFID tags including the NXP app notes]

these tags do not have an antenna - they are a grain of sand in the middle of a 3mm x 9mm piece of plastic. On either side of the grain of sand is a copper contact that you can solder to if you're careful. don't melt the plastic backing! the whole thing will probably stick to whatever it was resting on when you soldered it, so prepare. Make your antenna (a loop of wire probably, we are trying to figure out what works best) and solder it to the two contacts and then protect the thing with some hard (hitemp) hotglue or epoxy or something.

** AN0969 has a 98 mm long antenna design, with a read range of 1 m to 6 m depending on the substrate you use. Teflon and polystyrene are best; Rogers TMM6 is the worst but has the least variation across the frequency range.

The reason this matters is because we will end up having antennas in different locations (door at the top of the stairs, elevator room door, bottom of the steps) and we will want to react differently depending on where a tag is detected.

[[File:Rfid-SL3ICS1002_1202.pdf]] finally! we have the PDF for these tags.

[[File:AN173211.pdf]] frequently asked questions about these RFID tags.

we got these 900mhz band RFID tags available from mouser.com as part number SL3S1202AC0,118 they cost 7.4 cents each.

(the picture on the mouser site is wrong for these parts, they do not look anything like a 1206 capacitor)

[http://spaz.org/~jake/r/rfid-SL3S1202AC0.zip zipfile containing many PDFs relating to these RFID tags including the NXP app notes]

these tags do not have an antenna - they are a grain of sand in the middle of a 3mm x 9mm piece of plastic. On either side of the grain of sand is a copper contact that you can solder to if you're careful. don't melt the plastic backing! the whole thing will probably stick to whatever it was resting on when you soldered it, so prepare. Make your antenna (a loop of wire probably, we are trying to figure out what works best) and solder it to the two contacts and then protect the thing with some hard (hitemp) hotglue or epoxy or something.

* Antennas: From the NXP app notes:
** AN1523 has a reference design for a mid-range less than one meter read distance antenna. The antenna is 34 mm x 15 mm.
** [AN0972|http://www.nxp.com/documents/application_note/097211.zip] has a reference design for a "general purpose" antenna with an optimal read range of 2.5 meters. The antenna is 1.25" x 0.875"
** AN0969 has a 98 mm long antenna design, with a read range of 1 m to 6 m depending on the substrate you use. Teflon and polystyrene are best; Rogers TMM6 is the worst but has the least variation across the frequency range.
** AN1615 has a short range ring antenna design. 8.3mm diameter ring. Read range of 2 cm.
** AN1685 has an 80mm x 35mm antenna design, with a 6 meter read range.
