    You need a FET speed controller between the battery and the motor, The
    speed controller will read a potentiometer and vary the motor speed.

    He doesn't need to get that complex. He just needs a pair of 6V
    batteries, a modest sized 12V motor, single pole double throw switch, some
    starter relays and a pair of pulleys with very different diameters.

    He wants it to last a long time. This usually implies it needing to be
    very simple and over designed.


    The double throw switch and relays is so that the batteries can be hooked
    in series or parallel: Ascii art
