Can you power an arduino with a dynamo? Something like a wind up torch?

Thanks for any help!

Probably not directly, but if the dynamo (generator) fed a voltage regulator or voltage clamp to keep the voltage from rising above the maximum voltage allowed for the arduino DC input (Vin), it might work. Got a specific dynamo in mind?

hi lefty, thanks a lot for your answer.

I don't know much about voltage regulators, could you maybe advise on which one should I try? Should it be 5volts or 9 volts? and how many Amps? mmmh really not sure.

The dynamo I would try to use is a really small one i savaged from a wind up radio. I could maybe try and use the circuit and the battery that came with it but I am not sure that could work.. on the battery it saus: Ni-MH Cell 2.4volts 300mAh

What do you think?
Has anybody else tried this before?

Thanks!
