Most of this could be similar to the flashing lights and sounds of droid builds, which is why I wanted to share it. We have a "maker garage" at work where people teach about new things, and I learned about making my own circuit boards!
To start I attacked the LED part, it's simpler than the brain and seemed like a decent proof-of-concept. I'll do this backwards and show you what we ended up with. Tons of thanks to Hiroo Umeno for designing the actual PCB (I meant to help, but he was done before I finished describing it!)
This is a custom PCB from OshPark after I populated it with the components.
Unfortunately, I haven't gotten the soldering right, apparently I fried several of the LEDs in the oven But the board's good!
Hiroo designed it with an output plug so I could daisy chain them for other projects, but for now I don't need that, so that isn't placed. I also skipped C5 because the plug is a 90 degree plug, but I'd thought it'd be vertical
Compare that to the old board. 7/4 of the LEDs (eg: power) in the same space, much more neatly and probably about the same assembly time (well, once I figure out how to not fry the LEDs!)
Next time I'll chat about building them. Oh, and did I mention what a big help Hiroo was!
