Dave Lawton circuit
« on: February 24, 2013, 17:20:23 pm »
Hi to you all,

I want to use my gas splitter dry cell (using the H2 only for my car) by using a circuit which work with frequencies to avoid the big current consuming. So I stumbled on the Dave Lawton circuit and build it on this PCB (http://i1285.photobucket.com/albums/a600/knovos2/IMG00480-20130224-1419_zps826b8dd1.jpg)
In spite of all the effort I did not get the high voltage spikes (1200 volt?) according to the attached PDF-file cramton-lawton.pdf. Both sections of the circuit work fine but the output is nothing more then spikes from 8 to 9 volt at 0.5 amp. To adjust the 4 pots to get something done is a kind of gambling process I don't like it at all. Further investigation bring me to a guy named Ravi who added some big changes to the Cramton circuit which tells me the Cramton circuit is a good basic design but needs a lot more (see attached pdf-file Ravi Cell). His modifications seems to work very well but take a lot of time and money. It kicked me back in my chair, no I don't want to do all that. Back on the web I discovered a different circuit from Dave Lawton which does the same Stan had, a self tuning resonance circuit. Look at page 10-61 from the attached pdf files chapter10.pdf My question to you all, is it worth trying to build this circuit (http://www.leonknook.com/circuits/Lawton%20self%20tuning%20circuit.jpg)
and is there a PCB available (open source). Are there alternatives who are better or give good results?
Kind regards, Knovos.

Dear Knovos,

Can you draw how you hooked up yr coil?
If its bifilar, you must do it the right way.
Other question is with which device you try to measure the HV peaks?

This is the PCB circuit, Bifilar clockwise.
I used 0.4mm thickness for the wire, it should be 0.7mm.
I tried several smaller coils with no different result.
The core is glued together with some toroids from computer cables.
When I attach a magnet near the coil it is vibrating.
I use a multimeter to measure the voltage and use a very old oscilloscope.

Looks like to me that you did it all according common knowledge.
Dave Lawton stated that the High Voltage spikes are difficult to measure.
What he did, was cathing the spikes into a capacitor and lighted a bulb with it...

Sorry i cannot help more in this.
Btw. long time ago my buddy had contact with Ravi. Do not expect to much of Ravi's efforts, as well as of the schematic of mr. Crampton.
Without any scientific proof, or without any confirmation by an independent observer, we must stay realistic and assume that no extra ordinary results were achieved. Extra ordinary means from my point of view any results higher then 150% efficiency accordingly to Faradays laws of electrolysis.

Thanks Steve,

I have to do some more searching to find out what can be done with these circuits.
I will be back if I have something useful.

Kind regards,

Knovos.

Here is the PCB for the PLL Cramton-Dave circuit. http://www.courtiestown.co.uk/index.php/electrolysers/dave-lawton/dave-lawton-pll-full-kit.html

but it only works between 40Hz 18Khz, anybody could help to modidy it to achieve 46Khz? please any idea or info about who could help its very welcome.

Hy...Lawton circuits was the starting point for me too,but it will never achive what Stan did....its just amp restricting.

There are many investigations about the pulsating method for electrolysis and 40/44Khz its the base point for resonance and subarmonics. But better results in higher frequency. The PLL circuits as Bedini its a good way for best results but the differences on the cells need different frequencies thats why im asking to modify the circuit as i know adding capacitors it work in a different range of frequencies but my question is this changes in the frequencies generator affects the PLL or it will match the better frequency for resonance? i also think its mandatory to use the 5 coils transformer but im totally novice in electronics. maybe i am on mistake? any help/idea please?
PD: Meyers work its many things not only HHO, as i know now he used vapor (from exhaust) high voltage/frequency pulsed ignitionPlasma Spark), and the EEC, these elements help to use less HHO, i am 100% sure its totally possible to run a engine on water.  but will be the first step because its better to follow Tesla devices and extract the radiant energy, it is?

Peace and love.
