We produced 13 styles of DEFCON 22 badges for Uber, Press, Vendor, Goon, and Human types of guests. A complete USB programming circuit and full-access to I/O pins, power and ground make this badge useful well after DEFCON. The badge design consists of a Propeller 1 circuit, infrared transmitter and receiver, touch-pad buttons and LEDs. The badges are a required tool to participate in DEFCON’s largest contest. The badge’s primary purpose – aside from being the entry ticket to the conference – is to foster interaction among attendees and mark the start of a hacking contest involving cryptology, social engineering and programming. Propeller coder Jon McPhalen (J0nnyMac) and DEFCON contest organizer Ryan Clarke (LosT) provided the concept for the badge based on DEFCON 22’s theme They Live, a 1988 science fiction film in which the ruling class are actually aliens who manipulate the status quote to spend money, breed and comply with mass media messages. The talks can range from groundbreaking offensive research, to very academic research, to a wildly entertaining talk about dying and coming back alive.There’s also the story about stealing a hacker’s computer. The challenge with this Propeller 1 application was schedule – we would start the design in May and the conference was scheduled for August! We did the project successfully without a minute to spare – the truck pulled into the ‘CON while attendees were lining up! Speaking at Defcon is often considered the pinnacle of one’s career.

This is a dialog of our DEFCON 22 badge, made under the direction of DEFCON’s founder, Jeff Moss and his contest leader, Ryan Clarke. Parallax made two DEFCON badges (22 and 24). An electronic puzzle for attendees could win lifetime admittance with the Uber badge
