Hi-. I have a small DC dynamo I want to use ultimately to charge cell phones with. I have a five volt voltage regulator and an electronic filter that might clean up the output enough to make it acceptable to the phone. Failing that, it ought to charge a couple of combination power brick/hand warmers I already own.So my question is this: how do I wire a female USB plug for this use. I assume I only need the two wires.Hope somebody can help me out. Thanks in advance. via /r/DIY http://ift.tt/2yhxxiJ
