URGENT! WATER AS FUEL DISCOVERY FOR EVERYONE TO SHARE

[xbox hacker]

Here you go, this one (essentially, it is a PWM)  is apparently based on a Lawton circuit, I've built my first PCB prototype and it works, I have a few small quirks to work out, though I think they are due to a faulty pot.
I have put a 2 way switch between pins 4 and 8 in the oscillator section of the diagram, so that I can sync multiple units together, I want to be able to deliver more than just a single gated square wave. This project cost me a lot of time and money in bits and bobs as it is the first circuit I have ever built, but if you shop carefully, it can actually be quite inexpensive to build. I have made a PCB design so that you can make your own PCB with a laser printer very quickly, I have a little more testing to do to make sure that the printable version works properly and is correct, but when I am done I wil publish it.

PLEASE NOTE: This circuit diagram is NOT of the RPG4700 unit the Aquapulser people sell, this is an older circuit for something else they used to sell.

DOH!! I thought you were referring to the CDI item that they have now... and not the Lawton PWM.....LOL My fault.

There are many different vexus circuits out there. This is the latest ones available that does not take Greg’s approach to using an oscillator input (due to space limitation,

Actually there is ONE VexUs circuit out there ... the one I originated.  There are versions (few) of that one.  It required using some sort of pump (oscillator), inverter, DC-DC converter or equiv at the front end to get the charge as they all need.

Thought I'd clear that up.

I WISH Apparently it is a very complicated circuit. I'll do my best to get hold of a unit when I can, seriously though, why is there so little interest in the RPG4700? Just because a few I-want-a-free-lunch people complained about it not being free seems to me a bad reason to ignore technology that is quite obviously being well developed and performs ...
$350 is not much for an essentially plug-and-play device that will not require tons of tweaking and effort to generate a fat plasmoid.

You're right magpie!

$350. is not much for a complete plug and play plasma spark unit. Hopefully I'll be receiving the PRG 4700 soon so I can get back to what I really want to do!... which is experiments on my test engine   and not making electronic circuits

Thanks for sharing

Actually Luc?
Haha, making circuit boards and getting into electronics has been quite the learning curve for me
Several months back I managed to get a 160CC 4 stroke 6.5 Horsepower engine brand new at Princess Auto on sale for $100, the next week they were charging about double that so I'm glad I got it when I did. I have never run it or even put oil in it so it will be nice and clean when I am able to do serious testing with straight water and plasma.
