Complete instructions for this episode of Weekend Projects can be found at makezine.com/projects/pedal-power-phone-charger/ Convert AC electricity from an alternator into a steady stream of 5VDC to charge your phone or power other mobile devices while bicycling. Attach a bicycle generator to your bike frame so that as you pedal you produce alternating current. Convert that alternating current to direct current using a simple charger circuit housed inside an enclosure box.
