mm mean nothing to me :P
so I converted that to inches so I could understand

A little update from me...

I have a new idea for the resonance WFC.

I'm thinking to use electrostatic loudspeaker (ESL) transformers. The transformer is a audio step-up HV transformer and is connected behind a audio amplifier.

The resonance WFC which I'm building has a nano Farad capacitance, so a choke in the mH range to get the LC into resonance in the audio range (300-20.000Hz) is necessary.
The diode is acting like a frequency doubler.
The HV from a ESL transformer is about 1:125 (kV) and has mA currents.

A nice part is that I can use software on a PC/MAC to generate a sinus waveform and adjust the WFC into resonance.

Let me know what you guys think.

Those are too expensive , the ESL 's , specially the toroidal .

I say these high frequency xformers must be made at home , price are too much .

My new power amp uses transformers of audio type , it can be used foir w/e else and all can be used backwards and forwards ...

But I believe I saw a 50:1 esl EI type for about 50$ .

did you build your cell yet? any gas?

No Donald I did not build my cell , Perhaps we can trade services to make a cell for me , I will be about ready to test .

I am still not sure How a proper mounting point that can be a bit moveable should be made , maybe you have some ideas .

Here is the sine wave gen I use , this method is rock solid and always gives a 100% pure sine , it will never drift if your pot is not total crap . I estimate its cost @ around 8$ when purchasing single components .

I basicly dont like the idea os having a sound card producing a sine wave , bad for noise , ground plane  have to extend it with a wire .

As for my amplifying stage I cannot reveal it , top secret /: , too much research went into it .

Noticed mistake : the clock and input are inverted , the 74hc4060 feeds the input and clock is from ltc .

why do you need a sine wave? stan uses square waves with a pll

at some point this summer i'll build some resonant cells, starting off i'll do more tests with my current cell, but when i build the resonant one i could build another one if you wanted...

Stan uses a square wave *in resonance* , its like if you had a resonant filter .

Thus a sine wave .

I dont know why a sine wave should be used , its just cool I guess .

Transformers love sine waves . You cant run a television set witha  square wave inverter , it gives glitches , you cant run a motor with square AC , it loves the pregression of the sine . Radio waves dont penetrate matter with square AC , the best penetrator is the sine ...

I just some compkicated electrical physics physics , fast rise + impedance mismatch = reflexion .


Stan was a radar techician remember and he  , he would be a master at these short pulses pulses , I bet he could solve these issues that we can barely understand , it really is a specialised field . Thats what happens with radars, they use square cause it bounces bakc instantly .

 if you physically bend the coax cable not smoothly enough you get reflecion , bends on coax are real smooth for minimal reflection , electricity is more than just flow of current etc ,..
