When we started concepting this badge, we decided we wanted something that was fun, unique, and had use after Defcon.
The badge is based on an Adafruit Trinket and two Neopixel Jewels. Two buttons toggle between 9 color patterns and 4 transition modes.
We wanted to create a badge that anyone could easily hack on. Download the source and plug in a USB cable and people can easily hack on this project and remix it as they see fit!
