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. His first badge hacking project was to upload new images to show his appreciation for the lab.
