A Five-Year History of DEFCON's Electronic Badges

From 2006 to 2010, Joe Grand had the honor of designing the conference badge for DEFCON, the largest and oldest continuously running hacker and computer security convention in the world. The badges, which sparked a community now referred to as #badgelife, featured active electronics mounted on artistically designed printed circuit boards.

This presentation highlights the badge design, functionality, and hacks from each of the five years. Joe later went on to design the DEFCON 27 and DEFCON China 1.0 badges, which are not covered in this presentation.
