Why this one

Hand-powered generator for emergency charging or teaching demonstrations

The handle turns the crank arm and the 60-tooth ring gear. The gear meshes with a 15-tooth pinion, a 4:1 speed-up. The pinion shaft spins the rotor disc, whose 8 magnets sweep past 6 stator coils fixed to the housing back wall.
