Making the DEFCON 18 Badge

摘要

For the fifth year in a row, I've had the honor of designing the conference badge for DEFCON. Past badges have blinked patterns of LEDs, allowed you to create your own custom scrolling text messages, turned off your television, transferred files from a SecureDigital card over infrared, and pulsed to music using Fast Fourier transforms. People have hacked the badge to become a flame thrower, an audio VU meter, a password generator, an amusement park game, an anti-surveillance system, a blue box, and a polygraph, just to name a few.
