I wanted a reliable hand crank light that would not wear your arm out in times of need
A retro look was desired too
Step 1: Find A Good Stepper Motor
I found several stepper motors but they were either too big, or did not produce enough voltage at a slow speed
This one is from a scanner off a copier.
What makes it suitable are three factors, one it has gear reduction (increase from our perspective) this saves a ton of time, second it has two armatures stacked, these can be connected in series to double voltage(almost)
Third it's small and makes a solid 6 volts AC
At a slow crank speed
