Electronics and Robotics (generally known as E&R) is an ~800 square foot shop where electronics and robotics projects can be worked upon.

Training and testing

Training and testing is REQUIRED before using this shop, especially with regard to soldering irons and oscilloscopes. If you're not sure if your experience is adequate, please contact the shop lead. Sign up here for tool training and testing. We can also test on Wednesday night Circuit Hacking Nights, from 6 pm to 8 pm.

Availability

This shop is available to members 24/7. We have 14 benches, however not all benches have all equipment. If there is a class running, please be cognizant of your own noise levels to try not to interfere with instruction.

Circuit Hacking Night - Wednesdays, 6 pm to 8 pm

There is a Circuit Hacking Night every Wednesday night, from about 6 pm to 8 pm (and a bit later sometimes) which is FREE and open to the public:

Drop by to see what electronics can do for you, learn to solder, get help fixing broken stuff, get help with your project, blinky LEDs, sensors, DMM/Multimeters, motors, sparks, Arduino stuff, cables, wires, parts, how to read schematics, how to make circuit boards, etc!! Keep learning after any electronics class you've taken - think of it as office hours for electronics. And you will see what an oscilloscope does. No need to reserve a ticket just drop by, but if you do we can make a plan to help you.

You MUST sign in (our standard waiver) at the front desk. Anyone under 18 years of age MUST be accompanied by an adult at all times.

We generally run throughout the year, but you should call Artisans beforehand to see if it is running, especially during inclement weather. When holidays fall on a Tuesday-Wednesday-Thursday (New Years, Fourth of July, Thanksgiving, Christmas Eve/Christmas), we may not have the event. Again - call ahead to make sure!

Rules

• Please do not enter the 'Cabinet of Why We Can't Have Nice Things' without permission. This contains parts and consumables for fixing equipment such as oscilloscopes and multimeters.
• E&R is one of the few shops that has parts available for member non-commercial projects. Please do not take all of a particular part; if you see the supply of something running low, let us know.
• Tools should not leave the shop without notifying the shop leads. This includes soldering irons, oscilloscopes, wire strippers, flush cutters, and hand tools.
• If you don't know where something goes, do not put it 'anywhere'; place it on the top of the rear cubby area. Our inventory of parts and equipment is useful only if things are in the correct places.
• 
• Use a maintenance tag (found at the front of the shop) if you think something is broken.
• Use a project tag if a project is to be left for a short period of time.
• Please do not drop off 'donations' without contacting the shop leads to see if we can use your old parts/equipment. An email to us with pictures can let us know if we should take the donation.

Drift Bin

If a project is abandoned/unlabeled for any amount of time, you may find it in the Drift Bin. Please label your projects!

This bin is on top of Bench Alpha.

Parts Index

We have a parts index so you can easily find parts and equipment. See: https://wiki.artisansasylum.com/images/1/1f/ENR_Inventory.pdf It is also generally located on each computer in the shop, and on Printmonster, the printing station. The wiki version should be the most up to date.

Electronics and Robotics (E&R) is one of the few shops that provides parts for projects for FREE. Our general view on parts is that if you are building a non-commercial project, and are doing something cool, take what you need (wire, fuses, resistors, capacitors, switches, sensors, thermocouples, stepper motors).

Soldering irons, multimeters, oscilloscopes, benchtop power supplies, computers, measuring devices, tools (flush cutters, wire strippers, screwdrivers), and the like are NOT to be taken out of the shop.

Usage tips

• Use containers or cardboard boxes to transport projects, and label that container or box.
• Remember to shut off equipment (soldering irons, exhaust fans, oscilloscopes, power supplies) and return cables to their proper racks after usage.
• Turn out the lights if you are the last person using the area. The light switch is on the wall nearest to the social area inside the HAM radio shack/Bench November area.

Etiquette

Please follow this shop etiquette so that we don't have to make more rules. As the mighty and awesome Rob Masek noted:

"Rule Zero: Don't do anything that makes us have to create another rule."

• Fill out in-progress project tags completely -- with your name, contact information, and space number. A name isn't always enough information for someone to track you down if your project seems abandoned.

Layout

The shop has multiple benches and storage areas. The following will show the identification of the areas, which are needed in finding things from the inventory list.

Flammables

Flammables for E&R are stored in the yellow cabinet on the edge of the shop:

PrintMonster

Printmonster is the printing station, and is located at the front of E&R.

See https://wiki.artisansasylum.com/wiki/PrintMonster for details.

Bench Alpha

This bench contains an Ubuntu PC and Arduino sensor parts.

Bench Bravo - Raspberry Pi

This bench contains a Raspberry Pi station, to connect to Raspberry Pi types 2 through 5, and Pi Zero systems. Please do not remove connection cables from E&R.

  • Bins containing several attenuators for use with the spectrum analyzers and oscilloscope to protect them from high-level RF signals.
  • Bin containing many adapters for N, PL195, SMA and BNC connectors.

Storage Areas

These storage areas are carefully curated and inventoried. If you don't know where something should go, put it on the back shelf with a tag, and we will store it correctly.

Tall Shelves Alpha, Bravo, and Charlie

The tall shelves are shown below. Shelf Alpha is on the right, Shelf Bravo is in the middle, and Shelf Charlie is on the left. Do NOT climb the shelves, or stand on chairs to reach parts above.

Toolbox

The toolbox is located between the tall shelves and Bench Bravo. A shop style vacuum cleaner is below. Please do not remove tools from E&R without permission. When taking tool screwdriver or allen key sets, take the entire tool set to the bench. This helps prevent tools from missing elements.

Desoldering tools, desoldering wicks, flux and other soldering elements are in this toolbox.

XYZ Table

The XYZ table runs from the computer on the other side, on the rolling cart.

Rolling Cart

The rolling cart contains a Windows 10 computer hooked up to the overhead projector. The projector acts as a second screen, or can be configured to mirror the PC screen.
