Hardware:

Case idea: (laser) cut 2 acryllic panels, sandwich PCB w/ spacers, seal edges w/ caulk/hot glue.

Previously, tried to test test/program with FTDI board, using a 10uF(?), but failed. Need to try this again and/or put oscope on pins and see what's happening to the signal.

Software:

Possibility: No need for ftdi jack (maybe breakout for debug...), b/c on-board ftdi should work. Well... issue with this is that there's possibility for client to overwrite code. Maybe have special jumper to plug in to enable reset+program?

• Maybe have ATmega turn on an enable to FTDI
• For system flashing, have jumper pin to short the reset to power, so FTDI is enabled the whole time
  • Perhaps have jumper for the RTS signal b/n FTDI and ATmega too
