Bob Boyce's PWM3G pcb board. This is Bob's 3 wave square pulse circuit. It is his finding on the resonance frequency of water splitting. Fo tuning in 42.8K hz, then in half to 21.4K hz and then in half again to 10.7K hz. It is used in conjunction to the 6.5 Inductor Toroid iron core. U wind kit. More info on the PWM3G board and it's functions is here. ( 8/18/15) Also in a U solder parts and board kit. ( soldered up and tested)
