Ok, I *know* a stepper would be easier but this is what I have on hand, and I have to make it work.

I have a DC gear motor, a 3" wheel and a pot for speed control. Assume I can reach any speed from infinity down to zero.

I need to figure out how many RPM I need to move that 3" diameter wheel .280" in two seconds.

Like I said, a stepper would make this far easier but, I don't have one.
