This was one of those “Why Not?” moments. While sitting at dinner with family and friends the night before my graduation commencement, somebody mentioned that a light up Mortar Board would be really cool. Realizing that I had all the parts necessary to make one in my apartment, I went home and whipped this up just in time for graduation. Making the whole thing, including soldering, wiring, and programming took about 2 hours.
As always, this project is open source. The arduino source code, and the wiring schematic is available for download from GitHub.
Here’s a close-up video of it working (posted on my facebook the night before graduation):
And here’s a video of me demonstrating it on graduation day (posted on my secondary youtube account):
