Impressive work webmug, keep going!
Thanks Donaldwfc,

This simulation shows resonance effect.
Don't know if resonance can be simulated at the transformer secondary in this simulator.
I simulated resonance in the primary only. Thus 1:1 (should be 1:10 step up ratio PRIM:SEC)
Looks like http://jnaudin.free.fr/wfc/index.htm

I used the same model as above.

Energy transformed in the transformer from primary to secondary is important what frequency and core is used.
For me it is a huge problem right now making the transformer.

3M resistance is too much. more like 10kohm max

Webmug that looks good, I am not in a position right now to dive into the details to follow along, but I hope you are able to find a few more clues and translate that into a working system!

I have measured my cell, spec are in my project thread.
It is 2Mega Ohms 1.8nF. If you look at the jnaudin cell it is 2.94Mega Ohms. 250mm length 5.19nF. Mine is 140mm.
It is also variable because voltmeter is charging it. 10kOhm is too low for charging the cell to HV in my opinion.

My gap size is 2mm. If you have smaller gap size then it is possible you have lower reading.
Remember: SM talks about dielectric properties of water. We are using these properties for charging the water by means of plates.

Open for discussion...

I will do my best and I hope that others will simulate it too... I'm convinced SM did it too before he eventually build it.

I use this schematic for my VIC PLL controller, only needs a gate pulser attached.
Has a transistor driver, but I am using a MOSFET driver now. See my thread.

R1 R2 connected at 4046 chip regulates the resonance frequency bandwidth I use trimmers for all resistors.
UP DOWN is a Triangular wave generator for scanner. The lock-in circuit is off chip. PHILIPS had a chip with lock-in build in.
When locked-in, the chip 4016 switches are flipped to hold the signal into the PLL.

Home made bobbin and matched iron core  :o

Again, I have to say ... great to see good work actually following Stans systems (instead of being all over the place!)
is that circuit built or still under simulation? for the vic are you matching inductances?

That VIC PLL circuit is drawn from SM his schematics without the gas throttle regulation etc.
This is a minimal circuit for one resonance wfc cell I have build.
The PLL pulser, pickup, scanner, driver are functional at this moment. But my VIC coils are not for now.
I'm working on it. As you can see, I have a lot of trimmers (see blue round shaped on breadboard 10%) to adjust the signals. Adjusting sawtooth/pickup driver/PLL pulser signals from the pickup coil.
Front board is the MOSFET driver (see thread for circuit).

Thanks for the tip!
My SEC has same inductance as one choke... what do you think?
Chokes connected to SEC affects inductance so SEC self resonance is changed.

What is your opinion?
