I have a few parts laying around and would like to make a kalk stirrer. I have everything but the stirrer motor figured out. I know I can just go with a 110v 10rpm motor and be done with it. However i have a few stepper motors laying around as well. Does anyone know of a driver / controller that is a single unit? I don't want to have to hook up and program an arduino just to run the motor. I've found PWM controllers that would just need the driver connected but was looking for a more complete unit. I know there has to be some Electrical Engineers on here. Something akin to the Deltec K500
