I thought to create this project to share, this simple and very educational hack I found with these stepper motors. Here is a way to make using it as a generator really easy to put together into something actually useful to make use of some of those parts from those electronic kits that just sit around. This build is specifically designed to be built in minutes, not hours, and doesn't need a lot of electronics knowledge.

Supplies

2byj48 stepper motors

leds (most 3mm, 5mm, 10mm leds will work) just get one that lights up at around 3v and can take current of 20ma or higher

Optional crank handle (print file provided but will also work fine with anything else that makes a snug fit including some Lego parts or a pair of pliers or just your hands)

Attach LED

attach Leds onto motor (it doesn't matter what way, just plug in the same way and same slot as in the picture)

Handle & Spin
