Since DEF CON 29 was a masks & vaccines required convention, I wanted to make something that would make it easier to introduce myself and remain memorable to people who otherwise couldn't really see my face. I designed this badge to do that, but also to serve as a demonstration to other of how several off-the-shelf modules can be used to make something cool with just a little software gluing it all together.<\/p>\n\n\n\n

The full details of how it's all designed are available over on the GitHub page, but there were a couple of things I was really proud of.<\/p>\n\n\n\n

The 3D printed case uses custom-designed compliant buttons that worked really well to give a nice spring while being easy to print and the whole things snaps together to make it easy to show people how it's designed. A magnetic clasp holds it to a shirt or lanyard and the small internal battery can last for several days because it can sleep between button presses after the display is refreshed since the e-Paper does not require any power to maintain its image.<\/p>\n\n\n\n
