How to make a hand crank flashlight

This looks like a fun project. I think it works so well, or at least, seams to in the video because LEDs are so damn efficient.

I would make it somewhat differently, but this is good. For one thing, I’d probably make it out of an LED flashlight, swapping out the batteries for a motor.

And then, when you have your flashlight ready, you can do this!
