Pulse Width Modulator (PWM)

This is the completed PWM. It controls the amperage that the HHO generator will draw. Voltage is modulated as a series of pulses which results in a sine-like flux density waveform in the magnetic circuit of an electromagnetic actuator. The smoothness of the resultant waveform can be controlled by the width and number of modulated impulses per given cycle.

By using this I can make a 10:1 electrolyte which as is would draw enormous amounts of amps, but I can now control just how much the HHO generator will get from my alternator.

This is really not hard to build. You can get all the components at Radio Shack. All the schematics are included here. You can also buy a PWM like this for around $30. In retrospect, I have seen other PWMs which are far superior for about $120. Should this one fail in the future I think I will go that route.
