Making of the Defcon 18 badge

Posted on Monday, January 3rd, 2011 in code, firmware, hacks by the machinegeek

Joe Grand of Grand Idea Studio presents the backstory to his design of the Defcon 18 conference badge. (Joe’s talk actually begins at 09:05.)

The badge is based around a Freescale MC56F8006 16-bit digital signal controller and a Kent Displays 128-by-32 pixel reflective cholesteric liquid crystal display (ChLCD). Other functionality includes USB connectivity, seamless power switching, and hidden modes for a variety of contests held at the conference. Source code was developed using CodeWarrior for 56800/E Digital Signal Controllers. A single CR2032 3V Lithium coin cell battery provides the required power.

Joe has graciously posted the schematic, BOM, and all the tech docs related to this presentation.
