So the other day i seen a DIY spirograph so i figured i'd give it a shot. so thats exactly what i did. I used 3 motors with 1" round mirrors 3 pots and a ebay pen 532nm module. I think it came out pretty nice. it works and i think its really cool. one thing that bothers me is how hard it was to get the mirrors centered on the motor ends, i didn't get them perfect and you can tell because its kinda loud when they start spining so i'll have to keep messing with it to get it right but for now i'm happy with it.
