Using stepper motors as generators
Dino played around with some stepper motors by using them to generate electricity. The output is AC so he used a full-bridge rectifier, sometimes refereed to as the Graetz rectifier, to get a single direction signal, basically the absolute value of the sine wave. Check out the video to see it power LEDs, drive a motor, and charge some batteries.
