After the meeting on Wednesday I thought I would start a discussion on details related to electronics design and build resources. While my interests extend way beyond this field, it is my core competency.

First, I would like to suggest discussion of a goal. What sort of design and build capabilities should we have? Second, what do we need to get there? Third, how will it be managed? Forth, what can I contribute?

1. I would like to help create a space that supports a wide variety of builds. Bread boarding, wire wrap, single and multilayered PCB fabrication.

2. Given the discussion on Wednesday here is my list of tools and supplies:
*Course Solder Iron
*Fine Solder Iron
*Wire Wrap Tools
*Hand tools: Pliers, wire strippers, tweezers, screwdrivers, crimpers etc.
*binocular microscope
*O-scope
*Function Generator
*DC Power Supplies
*Parts! We have all been to circuit labs, we know what we need.

3. I have no idea. I know that I would like to have a wide variety of parts available (limit digikey shipments!). I would be nice to have an honor system where you record what you use. Would it work? Also, I have yet to come across a system of storing parts that I don't hate. Small plastic drawers, similar to the type used to store screws, are the devil.

4. I will make available my O-Scope, DC Power Supply, and Function generator. I am also willing to contribute to acquiring more advanced equipment. I also have an electronics work bench that is in fairly good condition.

Again, I am just framing a discussion. Hopefully this gets something started.

I think it is a good idea, and we should start planning this in all area's.

First as far as parts purchasing / storage / use. It would be great if we were at a point where we had funds to purchase a stock of raw material for any of our interests, but we know that has not yet happened. So I would propose we set up a storage area, and take the remains from our donated and dis-assembled gear as well as donations and set this up.

I also have gotten an O-scope from my father that I will bring down when the tool storage is set up, and a few more toys to bring to the electronics area a little later.

The only thing I will most likely bring before the makers fare will be a arcade game shell that I hope we can convert to a mame system as a group.

I've been thinking about this in my free time as well. After Wednesday's discussion I feel like we have a good handle on where the major blocks of things are going to go in our workshop, and after Saturday's clean up, I hope we can have things more or less in the right location. What this means is that we can actually get started building these workstations out.

I agree with the basic lists that you've put together.

Fume extractors for the soldering irons?

What about hot-air rework? Is that maybe a later thing rather than sooner?

One other omission is computers and programmers. I'm not sure if these belong on the electronics workstations or can just be on the computer side of the classroom. Some programmers/cables to consider stocking along with our computers:
- USBTinyISP
- STK500
- PICkit3
- Bus Pirate
- FTDI USB->Serial
- DB25 Parallel (for bit banging)
- DB9 Serial (for bit banging)
- Null Modem

I donated a STK500 programmer a while back.

That would have been nice to know before I figure out how to burn the sanguino bootloader to my 644p's using another arduino. But it was still a fun/rewarding process.

Sounds like you have something to write on the "wall of success"!

Yep, that's when I came up with the idea for the wall of success
