I do not have much know-how in the electronics world but I would really appreciate some help. I am fitting some EL wire on to my bicycle and making it pedal powered. I have decided to use an old printer motor to produce the electricity and did a small test and received about 3-17v and I am pretty sure if I go really fast I might get about 20v. I need to make it 12v DC so it will work with my transistor, but because the voltage would be fluctuating I couldn't use just one resistor. What could I use to make the changing voltage a constant feed of 12v DC?
Thanks in advance.
