Kapanadze and other FE discussion

[magpwr]

Hi,
Finally i have assemble the Kapanadze PVC support and Antenna after around 1 year of inactivity on this device.

Akula would likely use solid core copper "6 AWG solid core copper" which i used white shrink wrap as shown in yellow marker for Antenna.

This device was oscillating at it's own frequency around 80khz(Sine-Wave from kapanadze winding output) for input frequency around 10khz(parametric waveform, 1/3 sub-harmonics) which the circuit i have assembled was designed to operate  at 1/3(Frequency divider) of it's resonance frequency after 3 turn toroid which the L/C resonance test was around 30khz.I had overlooked impedance mismatch back then and did not measure voltage at the 26 turns on toroid after the kapanadze was operating at a higher frequency
Forgot to mentioned tesla coil was on pulse interrupted at around 1.7Mhz around (multi pulse at 55us...60us wide need to re-confirm again base on last trimmer setting)for the accelerated frequency 80khz which appear as pure sine-wave.
-------------------------------------
I am still the only person in this forum whom did not use resonance since my belief before the findings was the kapanadze winding needs to oscillate at it's own frequency but unknown at that time whether  it will go higher or lower than the drive frequency.------------------------------Hint for me was provided in this video of Akula device translated by Wesley.The device winding did look similar to Kapanadze and Akula was applying 1/3 resonance but in the reverse order.Coil was driven at around 55khz but the internal winding was designed to osc at 155khz which is around 3 times of input frequency.
--------------------------------------Reverse engineered Ruslan circuit and found that his device was using divide by12 (6 from 4017 and div 2 from Flip-Flop)
Tesla magic,prime number 3,6,9,12..That's all for now.It's late.

Hi everyone,
Latest findings while fine tuning device..many preparation to do before lift off.
Previously i mentioned 4017/74HC4017 configured as divide by 3 for Akula device.But the duty cycle output from 4017 isn't 50% (It's more like around 65% ) even if a 50% duty signal is applied to 4017 clk input.
Today i discovered the output of 4017 from mosfet driver is actually 49.5% and 50.5% since i am using small blue toroid(current sense) with 8 turns after the 3 turns from huge toroid(6mm sq) before the 0.47ufx2 Wima capacitor.The other i/c configured as divide by 3 with 50% duty 4xCLC previously shown in my youtube channel related to programming.This i/c no longer produce 50% duty if combined with current sense transformer.So in another words Akula is a smart guy.

I have attached the a pll image which previously i have made  modification for the pll circuit to work.
Only for the experienced just use LM393N portion an combine with current sense blue toroid with 8 turns combine with 74HC14.74HC2G14(SOT23-6).But i am not advising anyone to work on this pll circuit(Tested to be working after minor mod) since resonance isn't the key.

-------------------------
Tuning without HV enabled and w/o Grounding.I noticed that output from 26 turns on toroid is around 422Vpp at around 11khz near square wave with 100nf 2kv CBB cap.The kapanadze out is also connected to 100nf CBB capacitor.Variable supply settings 12.6volts at 1.9Amps.

Hi Magpwr i'm not trying to be clever here but trying to clear my confusion, if my Tesla coil is tuned to, for the sake of argument 1.728mhz it will divide down to a 'base 8' Don Smith chose 31.5khz that's a base 8 and 9  ie base 9 3+1+5=9  the creator the universe, don't know if you know what i'm getting at here but 8 is the other energy that involves the earth..

Anyway the Akula Tesla coil or whatever you want to call it generates a sine wave so in effect if you follow that train of thought your pushing the static field then pulling it, How does that work ? so to get one polarity or the other you need a 10Kv full wave bridge, and if you want to use a spark gap or some other device you need a charge caps up to some sort of timing
looks complicated like a TV EHT fly back thus using the one haif wave to charge the cap and the other as the capacitor dis charge as per Don Smith and Mr TKap'zy.

Your thoughts please AG

Hi AlienGrey,
I can't advise much on Don-Smith.But the only thing i understand is the lower the number of turns like Don-smith the higher the input voltage we need to use like neon-transformer with spark gap.
--------------------Back to Kapanadze the last round around 1 year ago i was using 6x10nf Mica 1000volts rated after 3 turns from toroid combined with 4layers on the primary coil in order to get around 30khz at L/C resonance signal test.
But i overlooked impedance issue with low value capacitor since i was focused on resonance like the rest and but i was applying 1/3 resonance.The output is nice sine-wave at around 80khz if tuned right and it will stay that way even upon power on.
This time primary winding reduced to 2 layers on kapanadze and capacitor value increased to 0.47ufx2 parallel.

The output of kapanadze will look like this as attached without applying power to telsa coil at around 1.7Mhz.The probe used was x100 but settings was still at x10  re-attached corrected version.My scope is now running on battery power via pure sine-wave inverter after measuring power consumption at 230v outlet to be around 28watts.On 12v battery uses 2.7Amps with scope on.Saved money on portable isolated scope.
The device will start hissing once the tesla frequency is right at around 1.7Mhz and the test pen will glow at a distance from ferrite rod to Antenna at 12volts tesla coil supply interrupted pulse at 260ns(each pulse) at around 55us wide for now.

I am still tuning device at the moment  with tesla and can't advise much for now and starting to kill IGBT now even with lowered varistor rating 150v from 470v.

Yes  that is fast it's almost a |X10-9 a charged partials travel about 12" in that time, I made a PCB for that PLL circuit you published and i made it
I couldn't get it to be Equally Waited on the 4046 output gave up in the end and the pick up circuit was also crap, how have you got the decide by 3 etc
connected up ? one way would be to include a 4013 after the 4046.
