Hey I need some information on how to build a dynamo powered radio.the radio currently works on 8 1.5v tipe D batterys.Any info is welcome.If possible a circuit diagram.
No diagram needed - just ten D type NiMh batteries (you need ten to replace eight normal batteries), fed through a rectifier. Feed the rectifier from the dynamo, making sure the polarity is the correct way round (or it won't work, the rectifier stops it).
Still, didn't think that was important, my mum's bike has dynamo lights which go out when she stops, except for a capacitor in the rear light which keeps the LEDs flashing for a minute or so.
