I’ve been exploring various types of gearmotors. DC motors by themselves spin too fast and have low torque. Gearmotors are motors with a gearbox that slows down the high speed of the motor and produces higher torque. Most gearmotors are pretty expensive though. I want a really cheap, almost throw-away, source of gearmotors. It turns out cheap servos can be made into continuous rotation gearmotors.

Sorry, the comment form is closed at this time.
is there an actual tutorial on how to do this?
Yup! Just click on the link that Limor provides below the video. Also, do a search on google for “continuous rotation servo” and find lots of other tutorials too.
oh my bad ;\
