Hy guys I just wanted to share my little setup similar to JL

That looks encouraging.   Please tell me those peaks are greater than two volts though.
Not 2v but not to much 7v....but hey that was a mini vic ~100winds pr,~200sec,100bif chokes....without wfc con voltage was ~1200v...at resonance....non resonance was30v with 12v on primary....so what do you want from such a small vic?I think it have proved the principle!

It would appear those high voltage impulses are being stored instead of shunted by the WFC.  That is the secret we have all been looking for.  The magic you may have found is probably in the implementation of your coils and the core, so make very small changes as you tune things.  Probably best to not even touch it and instead attempt to build a new one to scale up and go for higher voltages.  Now that you have something working, you'll want to keep it as is, so you'll have a baseline to fall back to.  A mistake many of us have already made to to keep modifying the same piece of circuitry.  Usually what happens is we break it and can never get it to work the same ever again.

Out of curiosity, were you scope probes connected directly to the WFC or where they closer to the output stage of the VIC?

good job!

 please document briefly your wireing scheme, resistance, inductance and physical parameters of the windings, bobbin and core.

that way you can replicate your successful components.

''The magic you may have found is probably in the implementation of your coils and the core, so make very small changes as you tune things''
I discovered no magic,and i know what you say,resonance of the coils looks like this(see att)

I kept it like it was,and of course right now i am working on  the bobins for a scale up version.
i made a little messy video today,on the left 3inch tubes,in the middle is a little bulb in series with the primary,and the meeter showing volts going down when the bulb lights bright and a little orange fillament when i tune the 10kpot and volts go up to5.4v(tap water)7v was on rain water..you cannot get the same volts always if you change the water...sorry for bad quality but you get the ideea!Cheers!

-Swiching bu208power transistor,but works whatever you want to put.

-transformer is like Stan's injector vic,all bobins on one core==>ferite rod 10cm long/longer the better,first layer the bifiliar chokes22awg,wounded end to end,next  1layer primary 24awg,3rd layer secoundary 30awg one layer,all wraped in the same direction.

-Wfc-3inch tubes 2mm spacing

*remember to hook the coils to the cell out of phase...if you hook them in phase you cannot get the amps down!

Hope is clear and simple and KISS,now HAPPY BUILDING!
