Hi!
I'm working with a cheap homemade laser projector that uses 2 hard disks actuators, works with sine waves and I am trying to make it so better and precise as I can.. I know i can't do much to make it precise because they are very open loop motors, but i'm trying to get the better results.
For the start, i want to know.. What i need to do for make a circle? I mean, between which frequencies should I get a circle? I think i need to play these frequencies and then adjust the rubber bands to get the circle...
Thanks for all!
