Re: Regulating power to a servo with a relay

A motor + a potentiometer + code = big servo

A window motor does about 20 watts, is fairly easy to use (if you just bolt your mechanism to the hub), you can use 2 for more power (or even 4 I guess), and it spins at a good speed.

A 775 does 266 watts at peak power, which is 66.5 times as much as the 4w servo. Add another (making that joint powered by 2 775's) and you will have 133 times as much power.
