True, though we desicussed this on IRC a few days ago, and cradek pointed out that you don't get the chopper-controlled current limits that you have with a commercial driver, so either you run at motor rated voltage and are limited to low speeds, or you have large banks of resistors and capacitors to create a constant-current source in a 1970s style. -- atp ------------------------------------------------------------------------------ Come build with us!
