There are a lot of college graduates out there, so you’ll want to stand out from the crowd. You can start by wearing an LED graduation cap with scrolling messages on the top.
Human person Dan Barkus has customized his graduation cap with a Teensy 3.2 board and a small Bluetooth module connected to a full-color LED that can display a handful of pre-designed graphics or, if he’s feeling a little cheeky, a customized scrolling message. The commands are sent to his hat via his phone. That is not a sentence I ever expected to have to write in my life, but there you have it.
Check out a video of the hat in action along with a second video highlighting how the cap was made.
