This is an early prototype of a hand crank generator which will eventually charge an internal battery and then be used for lighting and cell phone charging. Right now it's designed around the specific DC motor taken from an old broken printer. ... ...

I came across a project to build a hand crank generator that I thought might be useful to build. It sourced every part except the crank handle! I scoured e-bay and the local resale shops for a suitable donor handle, and finally, I got my own 3D...

Charging it up to its full 16,2V via the hand crank is quite an exercise and makes the Motor quite hot so so kind of thermal coupling to the enclosure is recommended. I added an LCD panel meter because oft its low power consumption. The device can be...
