Would anyone like a bluebox PCB or two?
This project was inspired by Don Froula's ProjectMF[1] in which he presents a PIC-based bluebox[2] 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 transluscent blue!
The firmware code[3] is done. I just have to do some tweaks once some test PCBs[4] 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.
