Bike dynamo help! Answered

I figured out how to make a bike dynamo.  How can I use the power it generates to charge a 12V battery?


I have done this.  What kind of power are you generating?  AC?  DC?  What voltage?

Well, I've changed it around a little, but I still need some help.   If igure instead of going to a battery, I want to make it go to a capacitor, to a voltage regulator, to a motor.  Can anyone help with the circuit diagram?

P.S. The generator is mostly just the Bike Generator by dbc1218.

Uh.  Hook positive to positive and negative to negative and pedal away.

P.S. you must be generating dc.  If not then put in a diode to rectify the ac.
