As for the board test rig i'll have to sit down and draw out the schematics. I used mostly stuff i had in hand, the only thing i bought was the LEDs, and made my own circuit boards.  I might even do a thread later on detailing what went into building it! its kind of a work in progress as i still want to add more functions onto it as i need them.

Could work it out myself, I guess, but if someone has already done it I prefer to use their work.
