MenofFather,

i modified my circuit according to your suggestion (28 turns secondary of the yoke in series via a 0.47uF capacitor with the multi turn coil)

I swapped the nano-pulser little toroid secondary leads, and now indeed the nano-pulse at 150V dc input is only 330Vpp instead of 1KV, but
also about 1/3 wider at 50ns instead of 15ns.

The 2x 60W / 220V bulbs are brighter due to the 28V secondary influence, but there is almost no pulse to be seen ontop of the 27KHz resonance sine wave.
Also no pulse really visible on the signal across the 2 bulbs.
Guess the pulse is to low to have any influence, and i probably need to inject it in an other way.

so I found a coil that was closer to spec, when measured it also has a 6'ish resonant point, with all the accessory coils connected.
the kacher generates moderately high voltage, but isn't great.  was tuning and testing with a power supply and a signal generator.
When I replaced the power supply with a battery, it wouldn't pulse as high.  I had to ground the negative of the battery to get it to oscillate correctly, and generate output.  so it's really picky about having all the peices of the antenna connected, and touching the ferrite kills the output.  I had the cuffed coil open, and when I connected the capacitor the kacher output (output of the grenade) was severely diminished.  eventually I had to turn everything off, connect the capacitor, setup the resonance for (45Khz, it's like 220nf) then enabled the kacher and it worked.  Even ended up at a opint the kacher was self-oscillating without the base resistor.  The composite of the 45khz (was low, only like 5V; needs a stronger drive than a signal generator) was slightly higher output than the kacher alone.  and can see the kacher in sync with the 45khz wave... was pretty stable match for frequencies.  The kacher is about 1.5Khz  (6/4) and needs to be cleaned up; my old secondary is also 'in the circuit' I accidentally put my had by it and got a small burning, and touched it, and it would be plasma... I heard a sizzling noise when I turned up my voltage, but wasn't getting voltage output... thought something was frying but maybe I had breakout. 
At a higher voltage on the power supply the current would go down and down... and the current was in error at one point, which is when I started to move toward a battery... at 12V was only 120mA, and my transistor remained cool. 
works better than my last shot.


previously any time I knocked the antenna off, the output would die (I dunno hard to say how much, was just +/-60V LEDs from ground) but towards the end, had a disconnect and it was still getting strong output...


the signal generator (45Khz) present or not has a stronger effect on my output; previously it didn't composite correctly.

Nope. It is an analog scope.
I don't see any particular reason for not going even to 5Khz. The lower the frequency the longer the current pulse cycle, the more the discharges you can do per cycle.

I would also like to thank T1000 for translating, and all of you guys for giving your best to this fascinating project.

hi Jeg,

Ruslan did ever mentioned in Russian forum the lower the frequency the better the output."Something like that"

But it's known fact that Air core transformer don't perform well in low frequency unless there is a medium-ferrite core eg:2000MNH .Recall SR123 device.

I would prefer to follow Akula explanation which Ruslan device is derived from.

But but but, the multi layer coil (2x 48, 2x 24, 2x 12) does not resonante at  range 18khz....37khz, thats the 2x 25 turn pickup coil with the 0.47uF
capacitor in series!

My  multi layer coil (2x 48, 2x 24, 2x 12) resonates (without any capacitor attached) at severall points starting at 950KHz - 4MHz.

And looking at your screenshot, i see a small high frequency sine wave of about 1.620MHz, and a bigger sine wave half of the frequency,
meaning 810KHz, not 27KHz or am i missing something?

hi itsu,

OK you caught me there.
Let me explain i was being really "blunt" when i simply mentioned "multi-layer coil" to save typing time.
It was catered for general audience assuming they have read all the older posting less than 4weeks back to understand where 27khz was obtained from.
"Very long sentence written does have it own problems" 

To be specific instead of multi-layer coil-i should have mentioned  the resonance frequency which is obtained from across capacitor "0.47uf" which is connected to 2x25 turns(Layered coil) in series which is winded on the opposite end of multilayer coil.This is connected to 3 turns of yoke.

  Itsu and All:
  Here below is an older video of mine, showing on my RMG replication how the feed back circuit can influence the brightness of the bulbs. I'm still trying to get back to where I was, with that previous circuit, but now using the yoke, grenade, and kacher coils combo.
  I was previously was able to light up to 7 100w bulbs, maybe even more, if I had had more of the right turning caps, but that's what I had on hand.

  Itsu:  Nice video.  I think that you are going the right way.
  Good call to reverse the yoke secondary coil, seams to make a difference.
Thanks...
