At Defcon 17 I competed with some friends in the badge hack contest. Friends had a home built Geiger counter,shown here with a hacked EFF “cat looks at butt” sticker. We interfaced it to the badge along with a wireless link and developed firmware that would allow the Geiger counter badge to send truly random bits to a PC for cryptographically secure...
