Tony,
Looks great. I'm impressed. I just got a mini box that I plan on doing the same thing too - so this came around at the best possible time for me. How did you do the battery? How did you isolate the positive lead from the case? Since the case itself is a ground, I guess (and I'm assuming here) if the negative terminal of the battery were to ground against the case frame its no big deal. But how did you isolate the positive?
TEACH ME OBI-TONY-KENOBI, YOU'RE MY ONLY HOPE.
