32 Volt Hand-cranked Generator

The vastly-improved second version of my tiny 2-volt hand cranked generator (   • Hand-Cranked 2V generator  ). This generator puts out up to 32 volts open-circuit and ~500 mW at optimum load, and can charge a phone/tablet. It's built from a pair of 60mm speaker magnets for the rotor and four 5,000-turn coils of 32 gauge wire. To get the fast rotation of the magnets, i use a 1:10 gear ratio.
