Kapanadze Cousin - DALLY FREE ENERGY

[magpwr]

That is correct.  The Kacher circuit has one purpose only -- to find the resonant frequency of your Tesla coil.  It is not needed and not useful beyond that.  If you use a Kacher and then switch to a signal generator, be sure to use the exact same gate driver and MOSFET, otherwise you'll be fighting the delays in the silicon and wondering why you can't get the same frequencies anymore.

If your Tesla primary and secondary is in the ballpark, you can use a signal generator to find the resonant point.  I just did this tonight and mine is currently showing about 10KHz on the fundamental, which is too slow.  The next harmonic is 20KHz which is too fast, so I need to make some winding adjustments.  I also need to raise the voltage a bit more, which means more turns on the secondary, which will force me to use the 2nd harmonic.  Just for reference, I have 190 turns of AWG 21 at the moment.  I'll post the final once I get it dialed in.

So why is Kacher circuit bad...?

Because you need to hard lock the base of the Tesla secondary to ground.  If you don't, the energy generated in the secondary will go that direction instead of going to the antenna where it is needed.  It's just like Ruslan said (again, imagine that), the Tesla secondary is an electric spring--you crunch it down and pops back out.  It will pop in both directions if you let it.  Don't let it leverage against the antenna and pop towards ground.  Make the ground solid so it can only pop towards the antenna.

So can you still use a Kacher...?

You probably could with some work, but you won't be able to use the base of the secondary for your feedback loop.  You'd end up using the antenna side which is going to be high voltage and if you mess with that too much, you'll kill the very signal you want going to the antenna.  You could probably wind a small "extra" secondary and use that for feedback.  I'm saying don't and here's why...

This whole device works on the principals of wavelength and wire length.  The wire length isn't going to change one bit unless you increase the length of your ground cable.  So why on earth would anyone do that.  Calculate your lengths, figure out what frequency you need to be at and use a signal generator (oscillator) to stay at that frequency, permanently.  No mess, no fuss, just simple concepts that T-1000 and others have gathered from Ruslan and Akula.

hi Dog-One,

I am glad you are  on the same page as i am.The waveform you shown below is also my future planning with flyback to kacher pri.

This is what i have completed applying interrupter pulse to 10khz 42% duty and achieve maximum spark length which represent KV using the lowest power by playing with interrupter frequency/pulse width.I am using 2sc5200 to drive 4 turns primary of flyback transformer which seems to produce better result than my SIC mosfet.

Side Note-Antenna if it's radiating RF out too much it means there are losses into thin air.Small observation playing with flyback and HV GND via metallic croc lead reveal there is attraction of leads at certain interrupter frequency.
Around 10KV peak pulse which needs to connected to dual spark gap and primary outer coil for the kacher which will be step up.This is the only way i gonna get 30kv+ Electrical field at the Antenna.
Akula using 32kv.If my theory is right i should see spark at the 5 cw,ccw ferrite rod if i am using screw driver or bulb at the ferrite rod.The secondary coil is winded with spacing between each winding like a EMP coil.
There should be a HV capacitor 50pf...<1nf in parallel with primary coil after spark gap experiment with 1kv air capacitor should produce result.

Akula is using thin white wire to drive the kacher primary coil if you observe carefully.This can only means he is likely using high voltage in kv.The typical kacher primary would need thick primary because it is low voltage but high current.

Forget about Ruslan he got nothing really after fooling us with single nanosecond pulse then to interrupter pulse.

Akula mentioned 32kv for some kind transmutation likely in the metal eg:copper to happen.I have attach the old Akula doc which was manually typed out from video(Russian,English below) which was translated for me by a senior Russian member MenofFather.

Everyone else,

Mazilli is a great circuit but the frequency is hard coded since it is base on the L(Number of Turns) x  C (Caps) Resonance.
PWM Generator is a better choice.You can save a lot by not spending on unwanted capacitors as normally used in Mazilli type of circuit.
The best choice is still PLL.

Dog-One. I have a question for you because I was interested in and whether increasing the number of packages is reflected on the light CFL?
it is this driver on both 74hc00 and TL494?
so just asking, yesterday working on the PCB of "Oleg" experienced small setbacks (I'll still have to work out the shortcomings)
but the effect is very similar to  your "screen"
We get set pulses from the The time breaker I wonder if this may TL494 frequency of up (Max) to 10kHz. it is not too low?
at Push-pull the input of one selectable give 15Khz. I mean the signal that comes through VD1- (4148) on the gate 74hc00.

in which the frequency range? the primary coil with three turns will be required?
I thought that will be high and this TL494 not cope ?

what's your frequency using?  to the primary winding of the Tesla coil and after the transition at the output?

Again.Nobody responded how to implement sinewave current peak detection to follow the load change. Dog-One ?

Note
TL 494 at 12v is a joke, when tested on bread board, i did not try it at 15 volts as was starting to get complicated, and the chip does not have over current cut off, any way frequency is limited.  EHT section also needs attention but not with a 494 it's a joke.

  The name Kacher does not originate from the Akula/Ruslan replication. It was invented many years ago, originaly called the Brovin Kacher, after it's inventor.  You can look in youtube or the Internet for more explanations.
  The Slayer/Dr. Stiffler Exciter is a low current version, which draws only mA, and not amps, to run and do the same thing, at much less current draw. As it uses a much higher value resistor, and a slightly different set up.

  Here is a looped version of the Kacher circuit, which is supposed to increase the output to an incandescent bulb.
As a normal Kacher circuit will not light an incandescent very brightly. This guy says that his, does.
Maybe it has something to do with what we are trying to do, concerning heterodyning, or maybe not.
