[Noisebridge-discuss] Help/Advice for a circuit board design.

I have a design for a project, and I was hoping to get some face-to-face 
feedback on the design.  I was thinking Noisebridge might be a good 
place to do that.

It seems that Circuit Hacking Monday's would be a good time to do that, 
but I would like to see if someone with experience/expertise would be 
willing to meet up with me at that time specifically to look over it.

The goal of the project is to build a programmable 8x8, 12bit color LED 
display, and to do it "cheaply", while still maintaining some level of 
quality. I had a prototype working, though it didn't support the full 
amount of current required. It worked when powered from a battery, but 
burned out a chip when I used a real power supply (the 74HCT238).  I 
added a high-side driver to fix that issue.

Anyway, if someone would be interested in talking with me about this, 
then I'll try to show up on a Monday night.
