This was a school project at Rose-Hulman Institute of Technology. It was for our Embedded Linux Class with Dr. Yoder. We found a similar project online that did it but with a Teensy. We decided to give it a try ourselves but this time with the PocketBeagle. We made the panel and packaged everything so it was as thin as possible. Right now it is not in a graduation cap but will be when we receive them. It will be displaying a custom sequence we make during graduation.
