Motor focuser

Hi guys. 

A cool diy project for you. A cheap motor focuser made from 2 RC place servos. Open both servos and remove all the electronics exept the motor. Next you need to find the stopper that prevents the servo from spinning 360°. Solder a cable from positive to positive and negative to negative. When you rotate one servo, the other one rotates as well. Fix one to the scope and attach a rubber band from the servo to the fine focuser. Turn the other one and it moves the fine focuser. Job done.

That is genius ! Respect !!

Would it be possible to remove the stopper and spin without limits as well ?
