Hello,
I am working on an engineering project that requires a hand crank powered USB power supply. Has anyone had any experience with these before? I am looking for one that would be preferably small enough to fit under a big shoe/boot and that has a strong handle, (I am going to try and convert it to work on the bottom of your shoe). Does anyone have any links to places I can find these and any suggestions as to which to get? Thanks,
Steve
