Some of the OSUOSL employees attended the recent DefCon 18 conference. One of the more uncommon features was the conference badge. In addition to being a ticket for entry into the conference, it’s also a hackable piece of hardware complete with 128×32 LCD screen, and microprocessor. The source code for the badge is available online. Corbin Simpson, a developer at the OSU Open Source Lab spent a large portion of his time at the conference developing and uploading new software onto his badge.
