I use timer1 for freqquency and delay() to start and stop frequency generation at certain period in milliseconds for the gate (on the main loop() ). It can produce frequencies from 130hz up to (at least) 100Khz (maybe more, up to 1MHZ).
you can use the tone() function instead but it can be unstable at high frequencies.
I could be wrong, but my feelings tell me that it does not work with that "high voltage" on the tube cells) that most people talk about. We can look at the "independent test evaluation report" as on some patents, voltages from 13v and higher (Resonant Cavity (Interfacing) )
Hydrocars I left the transformer on the shelf for now, I cant design an efficient one for now. One thing that I can observe with the shunt diode, is that the "ringing" of the coil self-resonance disappears. Stan used a shunt diode across the primary, can anyone confirm if it does the same effect? Thank you all.
I used a bifilar choke and 2 diodes, one like in Stan's schematic inline with the positive choke, and the second one the shunt one, linking the 2 chokes (see attachment).
Hello Hydrocars (and the others :-) ). I can confirm that part of using the chokes with no transformer, shunt diode is a must, otherwise the power of the collapsing chokes is wasted (during the pulse off time). Please people, play with it and you will see the "pulse doubling effect".
Steve, Andrija Puharich method is A.C. current, but it is not simple tune to the resonance. LC resonance is used to make use of optimal power transfer, not to do a magic.
Hello AdrianK. Thank you for all the effort you are doing in this area, sharing your experiments, you had made a intensive research on that. Sadly, some theories from Ronnie (yes, theories, not proven facts) may not work in the pratice. If we make some little amp leakage through the cell we get little tiny bubbles, but once the gas starts to be produced at higher rate (does not matter if on kilovolts or plain electrolysis) the bubbles leave the surface. You can do a simple experiment with an analog ammeter and the cell with DC, or pulsed, there is no significant increase on resistance to achieve this goal. Is just my opinion about that.
Hydrocars the one I remember was the waterfuelcell.org but I never saw that. I think that Stan's brother was in there, at least is what I saw over this boards.
LC resonance is not the key for the high production, I dont believe if we can get a "magic" effect of low power and high yeild of gas. This is not the voltage alone, there will be always current.
I'm not sure what point is being made here. Just because you have an increasing charge doesn't mean that there isn't a resonance occuring with it. Again I emphasize, by definition, resonance is a frequency. The DC current isn't producing the frequency. The pulsed primary and the choke + WFC are.
This is not about resonance, this is about restricting current in the most effective way (parametric resonance) :
