[[File:EagleCAD.png|400px|center]]
This workshop, taught by Electrical Engineer, [http://www.jeremyblum.com Jeremy Blum], will focus on using the popular [http://www.cadsoftusa.com/ Eagle CAD] schematic capture and PCB design tool to design a custom-printed circuit board (PCB) from scratch. Participants will learn how to create a schematic for their design, import part libraries, generate a layout, route traces, and export a PCB design. At the end of the class, participants will optionally be able to send their designs to a batch PCB fabricator so they can be manufactured (for a few dollars per board). Electronics experience is helpful but not required - all are welcome!

== Class Details ==
This workshop will be similar to an Eagle Workshop that I taught at HOPE-X in NYC. If you'd like to get an idea of the content, you can [http://goo.gl/8LI2fw check out the slides from that course here]. People [https://twitter.com/CryptixCoder/status/490666881796558849 seemed] to [https://twitter.com/paulcarbone/status/490625964322607104 like it], so I'm doing it again in San Francisco! The slides for this course will likely be slightly updated from those, and I'll share a link to the newest version as soon as it's ready.

Here are some pretty screenshots from the course:

</gallery>

== When/Where is the class? ==
The workshop will take place at the [[Classrooms#Church|Church classroom]] in the [[Noisebridge]] Hackerspace on '''Sunday, August 10 at 10:30 AM.''' I expect the class to last for about 2 hours.
The address is:
[[Getting_Here|2169 Mission St.<br>
3rd Floor<br>
San Francisco, CA 94110]]

The gate to the space should be open while the class is in session. If not, [[Getting In|you can read up on getting into the space by clicking here]].

== What do I need to do to prepare? What should I bring? ==
Bring a laptop running Windows, Linux, or Mac. Please install EagleCAD before-hand to save time. You [http://www.cadsoftusa.com/download-eagle/?language=en download it for free here].
You do not need to have any electronics or PCB design knowledge prior to this class. However, having a bit of electronics knowlege (ohm's law, etc) will speed things up. The class will be taught in english.

== How much does this class cost? ==
This class is free, as are all classes taught at Noisebridge. You do not need to register or RSVP - just show up!

If, however, you feel the class was beneficial, we'd really appreciate a [[Donate or Pay Dues|donation to Noisebridge]] to fund our ongoing renovation and lasting presence in the city.

== How can I get more information? ==

=== Who? ===
Everyone is welcome, regardless of experience level or age. If you have never made a circuit before and have no idea where to start, bring a few dollars ($10 to $30 to cover materials costs of a Brain Machine kit or other cool kits) and build it. Everyone gets personal attention, and everyone will learn enough to complete their project. If you have experience, please come and enjoy working on your project with others -- and share what you know!

=== Why? ===
Learn and share with others of all skill levels! You can come with an idea, or a question, or a circuit you want to hack. You can research ideas on the Internet ahead of time and come put them into practice! Or, you can learn with a large selection of easy-to-make kits that are available each week.

=== What can I bring to help? ===
No need to bring anything -- just yourself and your desire to play, learn, and/or share. We have everything you need. But if you like, you can bring:<br>
* Your own tools (we have all you need, but you can bring your own)
* Arduino / clones
* USB - serial dongle for your Arduino
* breadboards
* If you bring your laptop, we can set it up to program microcontrollers
* 9V or AA or AAA or other batteries (a bulk donation would be great)
* parts for your own project(s)

=== I am a blank slate! What should I do? ===
* make one of the many easy kits that are available each week.

=Event Calendar=
<onlyinclude>
Not all events make it onto this calendar. Many events only make it to the [https://www.noisebridge.net/pipermail/noisebridge-discuss/ Discussion] or [https://www.noisebridge.net/pipermail/noisebridge-announce/ Announcements] mailing lists, [[IRC]] or in person at [[Meetings | Tuesday meetings]]. Best of all, Noisebridge is about people getting together at the space in San Francisco to do stuff. DO pay attention, as some events just arise organically from the bottom up!

'''Want to host your event at Noisebridge?''' We like seeing classes and talks on interesting things pertaining to various subjects of hacking. Most of all, we like seeing familiar faces. Please participate in the space and our [[Meetings|weekly Tuesday meetings]] to see if we're the right audience for what you want to share before announcing a new event. Additionally, please see our [[Hosting an Event|events hosting page]] for suggestions on how to use Noisebridge for your event/class/workshop.

|title = Basic Income Wikipedia Jam
|description = <br>This will be a small gathering of folks working together to clean up the Wikipedia page for "basic income," which is a total mess right now and the first resource many people new to the idea will encounter. There are neutrality issues, citations missing, key events unmentioned, overly verbose writing, confusing organization: on and on and on. If you're into the idea of basic income, come lend a hand. We'll have snacks!

|title = Post-quantum Crypto Talk by Peter Schwabe
|description = <br>In 2012, Mark Ketchen, researcher at IBM, stated about large quantum computers that they are "within reach" and estimated a timespan of 10 to 15 years until such computers can be built. It is not clear if Ketchen is right with this estimate, it is not even clear if a large quantum computer will ever be built. However, what is clear is that such a computer will be able to break all asymmetric cryptography in wide use today. More specifically, it will break in polynomial time systems that are based on factoring (like RSA) and systems based on the discrete logarithm (like DSA, and Diffie-Hellman key exchange), including their elliptic-curve variants. There are asymmetric cryptographic systems that, as far as we know, are not broken by quantum computers, so called "post-quantum cryptography". It is obvious that once large quantum computers exist, the world will need to switch to such post-quantum schemes. However, users who are concerned about long-term security, have to switch to post-quantum schemes for confidentiality already now: an attacker who records and stores key exchanges today can go back in a decade or two and use a quantum computer to attack them. In my talk I will give a brief overview of post-quantum crypto and then highlight what we can, and should, already do today to provide long-term security in cryptographic systems. In particular, I will present the "NewHope" key exchange, which is currently used in an experiment by Google and is one of the candidates to be considered for post-quantum key exchange in Tor.

Lathe

What9:

[[File:Board9.jpg]]
[[File:Cummins_7x12_miniLathe.jpg]]

The motor belt for the older green Grizzly 7x12 lathe was missing, and the newer yellow Cummins had a broken speed controller and missing compount slide leadscrew, so I moved the electronics box and compound slide Grizzyly to the Cummins, and it worked in low gear, but not in high gear. I turned a few test pieces in low gear and it seemed fine. Took the headstock off and the plastic gear is missing a number of teeth. We might be able to pull a gear from the Grizzly, and there are plastic and metal replacement gears available, but I can't seem to press the shaft out of the bearings in order to replace it. An arbor press might be necessary. I have a project to do on it, so it will be back together next week (the week of May 2), but it'll only work in low gear. If we can get the shaft out, [http://littlemachineshop.com/products/product_view.php?ProductID=3453&category=6 here's the link to the metal replacement gear that won't shatter like the plastic one did].

== Rotating Tool Holder ==

The lathe has rotating tool holder that allows you to hold up to 4 tools at once and rapidly change between them. The bar on top loosens by turning it counter clockwise. The entire tool holder then can rotate counter clockwise by quarter turns. Turn the bar clockwise again to tight the tool holder in place.

[[File:Tool_Holder.png|300px|thumb|center]]

== Lead Screw Control ==

On the back of the machine, between the high/low control and the gearbox housing, there is a control lever for the lead screw, to engage the transmission gears. There are three settings, stop, left feed, and right feed. The settings have three dimples that hold the control in place. There is an accidental fourth dimple, smaller than the others, between the stop and left feed dimples. This dimple can be accidentally used, and doing so will cause the transmission gears to not fully engage, causing them to become stripped or break. Be sure to move the control all the way up to engage left feed.

== Gearbox ==

The lathe has a gear box that controls the relative rate of the chuck and the lead screw that allows you to move the workpiece automatically using the power feed. Changing the gears allows you to change this relative speed. This section explains how to remove all of the gears. Partial removal allows the operator to change gears. Reassembly of the gears can be done by following these steps in reverse order.

== About ==

I'm a nomadic tech entrepreneur. The center of my orbit is San Francisco, but I spend only about half of my time there. I spend the rest of the time out traveling the world. Noisebridge is my home hackerspace, but I try and visit other hackerspaces whenever I'm traveling. I write code and build software companies for work, but I like building physical things and dong adventurous things in my spare time.

== Projects ==

=== Sous vide machine ===

I made a sous vide machine, for cooking meat and eggs in a precisely controlled temperature bath. It's based around an Arduino Uno, a thermocouple for temperature measurement, and an acquarium pump pushing water across three immersion coils. I like to say that my favorite part of cooking is soldering and writing code.

[[Bookshelves]]

I helped [[User:nthmost]], [[User:Fineline]], and others build some new bookcases for Noisebridge, based on the golden ratio/golden spiral.

=== Welding and Machining ===

I've always wanted to learn to weld and machine metal. I've been gradually learning both over the past few years, mostly at Techshop, but some at noisebridge too. Well, mostly trying to get Noisebridge's metalworking tools online, really.

A few random photos of stuff I've done:

=== Wood turning ===

I'm into making wooden bowls from green wood. I mostly use wood I get from free from tree trimmers that discard it, usually by advertising it as free firewood on Craigslist.

Here are some samples of my work:

I saw a few pictures online of land yachts, and thought it woudl be a good weekend project. 4 months later, I was finished:)

I took it to the Nevada desert in March for the America's Landsailing Cup. I placed 9th in my class, which sounds impressive until you learn I was only competing in a field of 15. It's a very small sport in the US.

Here's what it looked like putting some finishing touches on a new sail at Noisebridge.

== Contact list ==

TODO

== Who can use the laser cutter ==

Only people who have been trained by an official trainer can use the laser cutter, in order to prevent unintended damage to the machine, operator, and Noisebridge.

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

# Ask a trainer if they will train you
# Schedule a time with the trainer
# Get trained
# Get your name on the list of users before the first time you use the machine

* maintaining a verifiable list of users
** users can be found at: URL

* maintaining a verifiable list of safety? trainers
** trainers can be found at: URL

== 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 YOUR WORK!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!

=== Fire ===

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 that you don't know what it is. 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 ==

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.

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.

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 ===

# Turn on power and ensure that the fan and chiller are running
# 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 ===

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.)
# 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!).

=== 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.
# 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 ===

# 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

== 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, 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.

| 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 of hydrogen cyanide

| Fiberglass ||
|-
| 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.

== Known good materials ==

These materials are known to be ok for use with the laser cutter. The speed and power of the laser cutter will need to be set appropriately for the material and thickness in use. Below is a table showing the suggested settings when cutting or etching them.
