The Bullduino was an custom board based on the opensource Arduino Uno specification, but shaped like the Red Bull logo. It served as the invitation to the second annual Red Bull Creation contest.

Applicants to the contest had to create something with the Bullduino and post a YouTube video. Team Instructable’s “Romance Pants” belt buckle was a top entry, where unzipping the jeans caused lights to dim, music to swell, and candles to be set ablaze! See below for a collection of contest entries done with the Bullduino.

After the qualifier, sixteen finalists were chosen to compete in the 72-hour build-a-thon, but in 2012 they worked in their own makerspaces and streamed video throughout the duration. All of the streams were then integrated into a 72-hour straight show, hosted by Tyler Hanson and Mike Senese.
