My only concern about the Fun Projects Voltage Regulator is that it regulates the output of the generator and not the generator field itself. You adjust the output of the 3rd brush to get 8 to 10 Amps then put on the regulator. Controlling the field strength which is essentially adjusting the 3rd brush is the best way to regulate the voltage out of the generator instead of converting to heat in the Fun projects regulator. The Fun Projects regulator does work very well. I am looking to find or design an electronic regulator that controls the field current. Tom Westberg has one for 6V, but not 12V. Finding electronic parts any more is difficult as there are no stores like the older Radio Shacks where you could find discrete components.
