After going through a plethora of different no-video display options, I finally settled on building a Split flap display. This whole project is a side quest from my real life platformer game. Going from mechanical counters, to rack driven 7 segment displays, with some stops in crazy mechanical adventurs along the way. This video tested my mechanical design skills, my electronics skills, and my arduino programming skills. I even learned some new things as well!
