Hey guys im making a ball mill and I have this electric engine I got from my old scooter...well i was wondering if there was a simple circuit i could make that uses a 9v dc wall adapter thing and plugs into the circuit that could make it run at 15-20 volts for 24 hrs without burning any circuit ..(or my house)
Also I wanted the circuit to have a pot so i could adjust the rpm ..
Thanks!
