Neat! I'd be interested in a board. I missed out on the ones being handed
out at HOPE in 2008 (The Last HOPE, for which a friend and I embarked on a
last-minute trip to NYC for I think around $150 total, for the both of us).

Would anyone like a bluebox PCB or two?
This project was inspired by Don Froula's ProjectMF in which he
presents a PIC-based bluebox and PCB (handed out at HOPE in 2008). A
big reason I like AVRs more than PICs is because the development software
is OSS and free. So I reimplemented Don's bluebox in C for an AVR
ATtiny85. The PCB started off an a drop-in replacement, but evolved into
something designed to fit into a Hammond 1591XXM box instead of functioning
as a lid for a Radio Shack 230-1801 box. The Hammond box also comes in
The firmware code is done. I just have to do some tweaks once some
test PCBs are made because on the prototype, I wired up the keypad a bit
strangely. The code implements a 13-key bluebox, a DTMF keypad, a redbox
for US, Canada, and UK, greenbox, and 2600 dial pulse. The PCB needs work
to correct some early design decisions that turned out to be non-optimal.
