The kinds of affordable, off-the-shelf RC servos you can find today are fantastic electronic commodities for building all manner of interactive projects. For a compact, closed-loop actuator, what more could you want for the price of a decent lunch? DJ’s had a rather beefy DC motor wasting away in his parts draw for years now, so he’s taking on the challenge of building his own gigantic servomotor!
