I've finished my work on designing and debugging a PCB to go with my
AVR-based bluebox program. Read about it and buy one at
https://661.org/proj/bluebox/.
This project implements a bluebox in C on AVR microcontrollers. This project
is roughly a reimplementation of Don Froulas's PIC-based bluebox, which was
written in PIC assembly. The resulting compiled program is intended to be
loaded into one of the following circuit boards. Currently the code
implements a bluebox, silver box (DTMF dialer with 4th column), redbox,
greenbox, and 2600hz pulse dialer. There are 12 memory locations of 41
keystrokes each.
I have more bluebox boards back in inventory.
