6V dynamo across a diode bridge, a 1000 microfarad capacitor, and a 7805 voltage regulator. takes about 3 hours of riding to charge cell phone to full. Can be expanded upon to suit other needs.

  • @Gutsyndicate this is from a Ugandan design actually. I bought the dynamo in Kampala and the rest of the circuits came from a local store sans the voltage regulator. Of course such technology has been around for ever and a day.
