Does anybody know?
The basics? A procedure? Anything i'll be glad with anybody's advice.
Start by looking up information on a car alternator, these produce AC. There is a lot of information available about them so you should be able to get an idea on how to build one.
Take just about any household electric motor (i.e. clothes dryer electric motor that you can find in a junk yard, or you can use a stepper motor out of a printer). Basically, use the input leads for the electrical output. Fashion a crank to the mechanical output shaft for the mechanical input. Voila! Motors and generators are usually reciprocal devices (but there are exceptions).
Separate names with a comma.
