Hello All, Google brought me here. Looks fascinating. I'm a part time student at Purdue in New Albany IN. working on a B.S. in M.E.T. The rest of my time is working full time outside most all of what I find interesting. What spare time is left goes to Arduino, some artistic pursuits, my wife, and fixing broken things I can't or don't want to replace. I googled "force to rotate" and found PF. Today I want to rotate a small decorative ships wheel in fairly random speeds, direction, and amounts of time. I plan to use an AtTiny85, L293d, with a 16V power supply to the motor via L293D. Happy to meet you over time.
