Tell us about yourself!
First, I built one of these with white LEDs that came with resistorshttp://amx3dprintsupply.com/collections/electronic...Then I built one of these using multi-colored LEDs https://www.amazon.com/dp/B01KUE7F6C The math was a bit difficult but it worked. Very cool!
Fun! I used some disk drives from an old tower and an Arduino I had laying around. I picked up an L293D Motor Shield here: https://www.amazon.com/dp/B01KYC8CZ8
