URGENT! WATER AS FUEL DISCOVERY FOR EVERYONE TO SHARE

[Aka]

who would be up to the task of making the changes to the Nexus circuit

I can remake it in the same style if you want but I will need to know the exact info for any part changes or descriptions needed so I can add them... but first I can remake the image and add the diodes images to see how it looks

@Chris31,

Thank you.

I use factory made PCBs. I send the gerber and drill files into a online database at the factory.
The PCBs are expensive but I think it is wort it. If you want very good PCBs then you must
find a PCB manufacturer in your country. I use the Eagle CAD when designing electronic.

All,

I found another problem with the inverter. The on/off opto control did not work as planned because
the 4047 IC just went high on the inverted Q output, thus clocking the power transistor on all
the time. I just removed the on/off opto and circuit. Will use a relay to control the inverter on
and off. Attached is the new circuit drawing.

Groundloop.

Thank you Groundloop I think and hope all is clear

let's move on!

@Groundloop, Greg or anyone else good in electronics, I have some questions.

Do you think it would be needed to have a higher frequency than 50hz?

If so, do you think we can take a cheap inverter like I just bought ($20. delivered) and modify it to a higher frequency?   

If so, can one of you spend $20. and experiment with it?

My thinking is, since these are so cheap and maybe all we need for now, we could use just the circuit from them and add the circuit board we will hopefully create (once we test the circuit) which would have the coil, cap, diodes and mount it all in a new box which would have the HV wire leads ready to connect to the plugs. All in one box ready to buy and connect for those who can't build.

Let me know what you all think.

Hi Luc,

I'm not sure if this will be of use for the Nexus style circuit but I solved the frequency issue for my type of CDI producing your water spark effect.

It needs to be said that my circuit triggering method is NOT what you would put in a vehicle.  The proper technique is either Hall effect or optical chopper on the distributor shaft. 

The diagram below solves my frequency issue by replacing the Charge Triac with a Charge Power Mosfet.  I also added a 470 uf -400 VDC Cap shown right under the FWB.  This makes a DC power supply of sorts.  The circuit has never been more stable  I am so happy!.

To anyone looking to experiment with a multiple spark plug CDI Plasma system, this is a very stable configuration.  In 'real' CDI systems the charge side is usually more sophisticated but the big Cap, FWB and Power Mosfet has solved several technical challenges using easily obtained components.

Enjoy.  Peace,

Greg

Hi bwb,

I know it can be confusing when new at this. Believe me this is the simplest it has gotten so far and It took a while to get here. I am trying to help you and others who will come or even those who are here but too shy to post there simple questions so they just keep reading silently in the background so not to interfere with the development and hoping we will post something they can understand.
How am I suppose to take your statement.Is it OK for us simpletons to ask questions here or should we stay in the background and not interfere.

Simpletons stay silently in the background and do not interfere

.
Just joking - Don't get upset

My hopes are we will come to a very simple circuit and or kit one could buy made or assemble themselves, it is a question of time, sharing and involvement that will bring us there. My hopes are to make it available for close to what it would cost you to buy the parts alone.
That would be great and I hope you suceed

To answer your question, there is no resistors in the circuit. Resistors would cancel the effect of the circuit. You also need to remove resistors from inside your plugs or buy non resistor plugs. Video demo: http://www.youtube.com/watch?v=-J2AHNZUZD0
All diodes in the circuit are in series.

I know there is no resistors in the circuit.
I also  know about the plugs! I have posted a link several times here for a online store that carries a wide range of NR plugs.
What I was wanting to know with the resistor question? I was wondering if running resistors in parallel with each diode as geovel156 did in his plasma circuit to help protect the diodes could be applied to the Nexus circuit. Reading up on diodes I found they say to do this to help stop the reverse voltage avalanche breakdown effect when running diodes in series..I will be using a12vdc to120vac inverter with1N5408 1000V 3A diodes and was needing to know what size resistor would be best to try because I had no ideal how to even calculate that and if it would even work.or if it was even needed. But since you say it will not work I will not even try it.Below is a part of geovel56 post back on page 21.

geovel56 Plasma Arc Circuit and part of his Reply #832 and Reply #834
"Sometimes a diode may not have all the proper characteristics as rated. If one diode is actually weaker and internally not functioning up to specifications, it will blow and cause a cascading chain of blown diodes. The 500K ohm resistors in parallel with the diodes equalizes the diodes".

Thanks to everyone who help answer my questions and especially about the "??half bridge rectifier??."

Goodby everyone--This will be me in the background watching

Hi all,

I know most questions relate to the Nexus circuit now.  But for the sake of those interested in understanding what I have posted I have included a diagram showing the equivalent circuit using a simple single relay.  If this helps in the understanding then I'm glad.

Peace,

Greg
