Hey My solution consists of a MOSFET rectifier bridge and a low-dropout linear voltage regulator that outputs 5 volts: http://www.iki.fi/~msmakela/electronics/dynamo5v/ a switching regulator would generate less waste heat and present less physical resistance in the dynamo. Maybe it's

Robin i like the idea of a generator to charge the neo, but don't like the idea of using my pedal power directly. Maybe for you it makes more sense to power off the screen and gps so you can get to your destination quicker :) In practice, people haven't been successful in regenerating
