I tried to make one, actually made a few. But the hub is an alternator that will put out more power the faster you go and if the power is not getting used you can have some high voltages. After blowing out several circuits, I measured over 30 volts (AC) going down a hill at 25 mph with no current draw other than my meter. That was when I figured out why I was blowing out circuits. And that is when I gave up and decided to buy a ready made one.

Good luck.
