On demand Hydrogen generation from water as a catalyst/fuel in the combustion process. Water cools the flame instead of liquid gasoline, which is a terrible waste in all internal combustion engines today.
(The things they DON'T tell you in car 101. :-) )

I have the circuit working perfectly (with clearly labeled variables now.) I can't imagine how much time/pulled hair this saves even WITH the learning curve of using a PIC/Basic.

I'll be using another, separate one dedicated to creating a custom square wave (PWM) needed for another part of the design.
