Worlds Smallest Bipolar Stepper Motor with Arduino
Channel: MrScriptster
Date: 2011-12-22

This little bipolar stepper came out of a laser diode sled of a Bluray drive. It was INSIDE the sled! The entire assembly, including the stepper motor, the lead screw and the linear stage, the lens and, remarkably, even an end position sensor (which I've yet to connect to, it's under the screw) is 14mm x 9mm x 4mm. Sorry the Arduino is not in the picture, it's just too big to fit! I'll try to post more details on my blog at https://elabz.com/ shortly.
