Power up those USB devices with your pedals

Nobody in Europe would ever have had the idea to use a modified 275 dollar electric motor as the generator. As commenters on the page have pointed out there’s this great invention called dynamo…
The circuit design is helpful, though. Circuit board plus hub dynamo would be a great touring setup to recharge a GPS or a flashlight. Maybe I should dust off my soldering iron.
