To those who have followed and who are just joining, I'm still here, and will be posting updates again. Check my youtube channel for the latest videos.
The idea is to step charge the electrodes. The water tank acts as a capacitor. When the dielectric breakdown voltage of the water is reached the capacitor overloads and HHO gas is released. Current flow is instantaneously cut by the the pulse generator. The process repeats. Step up coils produce the high voltage needed to break the H20 bond. Bifilar chokes increase resistance to current flow enable a resonating effect. Oxide buildup on the 304 stainless steel pipes further curtail current flow.
Experimenting with stock thread as electrodes.

I was trying to avoid the 555 timer chip, but decided to give it a shot. I built the left half of the circuit which produced a nice clean square wave. I had the idea to remove the 100 ohm resistors at "mark/space" and "frequency" to try and improve range. KIZZAP, followed by smoke and the odor of a well toasted 555.
Now working on a new circuit board. Hoping for true square wave. Going to try passing the output of board 1 through board 2, and vice versa. Mosfet wiring soon...

For my pulse width modulator, I am using an LM324 14-pin quad-op-amp IC. Utilizing just one of the op-amps generates a variable frequency sawtooth wave. I replaced R4 with a 100K ohm potentiometer, and C1 with a 100pF capacitor. A 500k ohm potentiometer in place of C1 (coming soon) may allow even higher frequency.
It works! Mean frequency adjust via potentiometer knob
Max Frequency (around 8khz) Low Frequency (around 200hz)
Other designs utilize all 4 op amps to compare, filter, and buffer the signal. This may prove useful. As of yet, I have not tested this circuit in conjunction with the cell, nor attempted to vary the duty cycle of the pulsed waveform.

Tubes should be of 316L grade stainless steel to prevent corrosion. The outer tube should be notched and tuned with a guitar tuner to match the frequency of the inner tube. A properly tuned cell will ring when energized in air.

Plastic bolt head covers were cut into fourths and wedged between the two tubes, 2 per end, 90 degree offset from end to the other

12/24 volt 10/5 amp trickle charger was the initial power source. No coil or pulse generator yet... I put the 12/24V battery charger on the oscope. It's waveform is far from clean DC. A 200V 330uF electrolytic capacitor, should filter the incoming signal to reduce transient ripple.
With 12V input, the output signal of the LM324 circuit is only 2V. The range of the LM324 is 4-30 V, so combining boards without a FET is impossible. Still hoping to double modify the wave to turn a pulsing wave [_-_-_-_-_] into a pulse train [_-_-_-___-_-_-___-_-_-_]
Found the ultimate video. It is the ideal wave form, but I have no idea how to build it.
