It probably is a multi-wave LC delay line or in the sound industry a vibrator/echo chamber.

As I do not know how it is wound (a diagram would be good), that is a guess.

See attached which is multi-phase if the inductances are different on each side.

Mike

Mike,

thanks for your insights, my Grenade coil is wound as mentioned here:

Hi Itsu,
I did a lot of work on grenade research together with Lostbro years ago.
Our goal was to create a grenade 37.5m which also has its resonance frequency at 2Mhz.
The wirelength of 37.5m would give a oppertunity to create a 1/4 standingwave at 2Mhz which means it has double resonance.
Vew months ago I succeeded in realizing this 2Mhz resonance goal.



Hi Ape,

good to see you here, i think Nick can now remove your wrong post in the other thread


I used my nanoVNA to measure the Grenade especially the inductance (upper graph) and the impedance (lower graph) over a 10kHz to 20Mhz range.
But i first made the same measurement using a 47uH choke for comparing:






The result of this 47uH choke is this:



So we see a slowly increasing impedance (lower graph of the 2) till resonance at 10Mhz.


Then i used my Grenade:






The result of my Grenade looks like this:



So we see a starting inductance of around 160uH at 15kHz (upper graph of the 2) till a resonance at just under 2mHz
So my Grenade (inclusive Inductor and Antenna) has similar parameters as yours (2Mhz resonance).

   Max:  Did you figure out why your unit is flipping the over amp protection circuit. Does your mosfet get real hot. It may be that you have too much current going in.
I use a couple of chokes at the input, as well as some filter caps, as per the Ruslan, or Stalker's schematic. This diagram below, was for the induction circuit that I replicated.

    NickZ

Hi Nickz,
Am still working on it. I think it's the back emf effect and I have used snubber circuit to reduce that ,. But it's not enough.  I really want to get the voltage feeding my Tesla controlled circuit  up to 130vdc and above because that is where the effect is in most cases. At that stage you see it shaking violently on scope.

As for weather my transistor is hot the answer is no.

Hi Max,

when you say "At that stage (>130V input) you see it shaking violently on scope" what do you mean with "it"?

Is it not the intense HV HF from the kacher influencing your scope?

I remember several times with a strong kacher my scopes go crazy.

   Good to see you here, and that you are posting again, and hopefully building and testing also.
 I followed you on the OU.com thread, but, you quit posting there. So, good to see you here.
   I'm also hoping that Geofusion chimes in, "Hello there guys", as well. And any other builders, like Vasik, Tomtech, and of course me as well, as I plan to focus on these devices, and continue on with the tests and trials.
   I'll let my other thread on this forum, go out of site. As I can't seam to be able to remove it.

   PS. Max carefull with those high Kacher voltages, once you have a scope. You may have to NOT use the negative black scope lead, as once you put both leads on the induction circuits, with the Kacher also on, you'll be grounding the positive Kacher pulse to ground, through the scopes negative lead, due to the scope's grid tied ground connection. As well as sending all that voltage to your push pull's delicate circuit. Also at 130v the HV streamer will ground out, anywhere it can. The effect generation has been shown working even as low as 12v.
Ruslan mentioned that you don't need a "strong Kacher".  The ideas is NOT to add, but to interrupt the induction circuit's field instead. Of course when adding 130v to the circuit, things will fry, immediately. Just trying to avoid you burning up your scope, and circuits.  But, I did notice that your streamer can be barely seen, so, not sure if you have the duty cycle set very low, or why that spark is so small.  Anyway, good luck with your set up.

Hi Itsu,

By comparison; when you compare the scope shot of this video ;https://youtu.be/J7du9f-f9t0
To the scope shot of this; https://youtu.be/oC-YP1aDj4Q , you will notice the difference in signal movement. The later could not attain the violent movement of the former because voltage lever is low(maximum 65vdc) and few pulses. Any attempt to increase either of them( voltage or pulse) beyond a certain limit, device will trip off. Whereas, that is the moment of current addition.

And if the Kacher coils aren't tuned to the right self running frequency, the circuits frequency trim pots controller will not really make up for it.

Thanks for the piece of advice.

Ruslan mentioned that you don't need a "strong Kacher".

He was referring to those blazing Tesla coil build like those called Slayer that could arc up to 20cm and above.

If it doesn't interrupt how will it add.

Maxolous



    Max:  The kacher signal will do nothing to improve the output of the induction circuit pulse, IF, the kacher signal is not in resonance. And if you don't have a proper earth ground line, also. Your kacher looks too long to provide for the right frequency needed. About 1.5MHz or so. Not like yours which is running at too low a frequency for resonance.
5mm streamers should be long enough, more will cause problems. There should be no violent shaking going on. That is not a good sign.
   Please connect some bulbs. To see any real interaction. The load of bulbs needs to be above 300 to 500 watts, so as to not be fooled by the improved output, due to the addition of more voltage and current from the Kacher. A smaller load of bulbs will light up more, but, with no OU, nor able to self run. So, don't be fooled by that.

   Max, the ideas is not to ADD, anything. The purpose of the Kacher is an interruptor circuit, not meant to ADD. Meant to STOP the induction circuit, instead.

For those that think that what Ruslan said about a simple kacher not able to add anything, because it's AC signal will take away what it gives, should see my video, showing how I can light even a 100w bulb, at the grenade's output, with just my Kacher on.

   The idea of the kacher is that it is what Tesla calls an interrupter circuit. Meant to stop the induction circuits pulse, so that voltage as well as current will be increased.
 Like my analogy of pinching and quickly releasing the water hose, to see how it increases the force of the water. In our case, the output at the bulbs, and at the feed back circuit.
  Much of what Ruslan mentioned, is BS. If it wasn't for Oleg, his circuit builder, he would have nothing to show for it. I do trust what Stalker says, instead. And he has the best videos.

   Max:
   Yes, that is the idea. Now, to put it to the test. But, tuning is the toughest part, and not easy to get the all the right frequencies working properly, as they should.
That is why this is all so difficult to do. And if the grenade output is not sufficient, the feed back circuit will not produce hardly any output, and possibly not even light its green Led indicator.

Max,

so looking at both screenshots:

I see 1st screenshot the (yellow) kacher ringing down completely, but it seems the kacher signal is not there all the time it seems to skip 1 or 2 pulses compared to the blue square wave, making it look like a violent type of signal.

Hi Itsu.

Your observations are right. The first signals were taken while the probes,(blue) on push pull ic output, put while the second probe(yellow) hung around the antenna of kacher. At this time the signal from kacher was grossly absorbed, so I have to zoom in to bring out the scope shot. Hence, the low amplitudes.


Quote from: Itsu on 2023-05-26, 16:52:26

But you trigger on the blue
signal using a video type triggering and the blue and yellow signals are very low amplitude (500mV/div. only).
Also, the blue signal frequency is 46kHz but as said with very low (too low?) amplitude.
The kacher signal seems to be synced to the start of the blue rising pulse.

The signal of the kacher started at the start blue rising edge because that was where sync took strong effect. Moreso, at this stage I have not built in my delay circuit to delay pp signal. Remember, when Tesla is late pp must be delayed. That was what you saw in the following shot when the signal was at the crest. The freq of 46khz you saw was as a result of kacher effect, you already know that it may double or triple.

Quote from: Itsu on 2023-05-26, 16:52:26


In the 2nd screenshot i see the yellow kacher signal more as unidirectional pulses at 5V/div and also the blue square wave is now 5V/div, but at a lower frequency of 25kHz.

The unidirectional signal you saw was taken from gate of mosfet unlike the first screen shot which depicts signal taken from above kacher antenna and it was oscillating at it resonance freq.

Quote from: Itsu on 2023-05-26, 16:52:26

You now trigger on the blue signal rising edge, with the yellow kacher signal synced to almost half of the blue signal pulse.

At this time  I had Incorporated delay cct. So, sync became effectively strong there

Quote from: Itsu on 2023-05-26, 16:52:26

 
So what i am trying to say is that both screenshots show very different circumstances and settings and without any information on where these signals are taken from (diagram), it is very difficult to diagnose any problems.

They were different time actually.
I was only trying to show you how I should have it if not that it was tripping off. I couldn't go full throttle.

Quote from: Itsu on 2023-05-26, 16:52:26

I will figure it out soon.
Maybe I need to put a diode in my ps.

   Another point that I want to mention, is that the Kacher signal pulse may need to be ideally placed at the Off time of the push pull signal pulse, instead of on the ON time. As there is less resistance at the OFF times.  But, of this I'm not certain, as I have not tried it. But, I think that itsu did try that and did not get much better result, or output while testing. However, I still think that it's worth a try.

   Below is an image from Stalker's video, although it may not be his scope shot. The idea is what counts. And will also need testing. Remember that if there is no ground line, nor resonance, then don't expect that magically the placement of the Kacher signal will make any difference.
   The earth ground line, at about the same size as the grenade output coil, or 1/2 size made of welding cable, and Kacher to induction circuit resonances,  are prerequisites, to seeing any effects, at all. Sometimes I can go for days without the slightest effect of what I call the Radio Moscow, sound, nor any other signs of resonance, or improvements. That hissing sound does indicate some form of resonance. In my opinion. Along with the ability to light several 100w bulbs brightly. Not just barely...

Hi Nickz,

You are completely wrong there. You have to know what you're doing if you must make headway building this contraption. It doesn't give room for mediocrity.
You must be meticulous about it. Otherwise, you could do 99% and still not have effect. You see, right shoe for right foot and left shoe for left foot that's how it works. I made a video about that.

https://youtu.be/Bi7Wqpo9ihw

You must choose where to put it according to your push-pull side.
Your two signals from your pp are displaced by 180° . You cannot choose one as been fed to your controlled tests and put it on the other.

I found out that there are so much deception in the net. Most cct were perverted.

Max,

thanks for your explanations, although i still have some questions like when you say:

"The first signals were taken while the probes,(blue) on push pull ic output" does it mean that the push pull ic output only outputs a 1V amplitude?

or when you say:

"The freq of 46khz you saw was as a result of kacher effect, you already know that it may double or triple" does that mean that the kacher is causing the push pull IC to almost double its frequency? I never saw that happening with me.

By the way, again looking at the scope, the 1st blue signal period spans 6.6 divisions of 5us meaning 33us or a frequency of 30kHz, so not the shown 46kHz (15us positive, 18us zero, so a duty cycle of 45.45%).
The 2nd blue positive signal spans 3.4 divisions of 5us or 17us, so if with again 45.45% duty cycle, this means a frequency of 27kHz, so no tripling or doubling and the shown 46 and 25kHz can not be right.

But i understand you are still looking for the reason your device is tripping off and as you are the only one knowing how your device is build up, i wish you success with that.

Edited some wrong timing calculations

   Max:
   What I mentioned above are NOT my ideas, and therefore I am not "wrong".
As mentioned, I am just repeating what Stalker has suggested, in his video. Not trying to force MY ideas on you.
   If you think that Stalker is wrong or lying even, then so be it. But, it's not me that said that, but him.
   So, therefore when you say that my comment is "wrong", well, it may be, and is why I'm putting it out there to be tested. Itsu may have given it a shot, but, as mentioned unless you have your tuned earth ground line and Kacher/induction circuit resonance in place, you are not really testing what happens to these circuits.
    Also, we can't tell what you are saying, on your videos, at all. Sorry.

   When you say in your post that someone is "completely wrong", (me),  you should be completely ready to explain why you think so, and have some proof of that.
Otherwise, we get no where, and I do feel that Stalker is not trying to fool us. Nor is he trying to make a profit on any of this, as Ruslan, and others are.

Max,

thanks for your explanations, although i still have some questions like when you say:

"The first signals were taken while the probes,(blue) on push pull ic output" does it mean that the push pull ic output only outputs a 1V amplitude?
I haven't measured it anyhow, signal voltages from pp ic output are usually small maybe 2v or 3v

Quote from: Itsu on 2023-05-26, 20:43:47

or when you say:

"The freq of 46khz you saw was as a result of kacher effect, you already know that it may double or triple" does that mean that the kacher is causing the push pull IC to almost double its frequency? I never saw that happening with me.

Due to the shaky effect of kacher on pp, yes. Apparently, scope sees more signals than when  pp is steady.

Quote from: Itsu on 2023-05-26, 20:43:47

By the way, again looking at the scope, the 1st blue signal period spans 6.6us meaning a frequency of 151kHz, so not the shown 46kHz (3us positive, 3.6us zero, so a duty cycle of 45.45%).
The 2nd blue positive signal spans 3.4us, so if with again 45.45% duty cycle, this means a frequency of 135kHz, so no tripling or doubling and the shown 46 and 25kHz can not be right.

The second build signal resonates at 25khz I might not remember the freq. of the first build of head

But i understand you are still looking for the reason your device is tripping off and as you are the only one knowing how your device is build up, i wish you success with that.


Itsu
Yeah!
It should not be much problem. The first build didn't have such problem.
I will find solution to it soon.

   Max:
   What I mentioned above are NOT my ideas, and therefore I am not "wrong".
As mentioned, I am just repeating what Stalker has suggested, in his video. Not trying to force MY ideas on you.
   If you think that Stalker is wrong or lying even, then so be it. But, it's not me that said that, but him.
   So, therefore when you say that my comment is "wrong", well, it may be, and is why I'm putting it out there to be tested. Itsu may have given it a shot, but, as mentioned unless you have your tuned earth ground line and Kacher/induction circuit resonance in place, you are not really testing what happens to these circuits.
    Also, we can't tell what you are saying, on your videos, at all. Sorry.

   When you say in your post that someone is "completely wrong", (me),  you should be completely ready to explain why you think so, and have some proof of that.
Otherwise, we get no where, and I do feel that Stalker is not trying to fool us. Nor is he trying to make a profit on any of this, as Ruslan, and others are.

   NIckZ

Nickz,

For my video, I think you will hear me better if you put on your earpiece. Sorry for that.

Stalker specifically pointed out that  pulses are put at the start of a rising edge. That was demonstrated in one of his videos when he spoke about delay cct for pp. However, I found out that, a longer delay could shift the sync position farther to the crest.

Now, if you took one output of pp signal and fed it to the controlled Tesla and put your scope probe on the other one, it would appear that the off period is where your kacher signal is. I hope you get

If i remember correctly, the kacher needs to be fired on a specific moment compared to the Inductor sine wave like shown in this screenshot Nick provided a few posts ago:

Where that specific point is in relation to the Push Pull signal (creating the Inductor sine wave) i am not sure yet.


By the way, my Push Pull  (TL494) runs on 12V, so its output signals are 12V going to a TC4093 (for delay) also running on 12V so with also 12V output signals feeding the MOSFET drivers.

   AG:
   As I had mentioned, although the previous scope shot that I posted may not have been from Stalker. However he did post it on his video as an example of what to look for.
Sergey's directions post below was from Stalker. Might be interesting.
It was sent to me by one of our members here. As he knows that I have some faith in what Stalker says. Possibly some of the ideas may not be translated quite right, though.
   One of my doubts is his grenade frequency, of 15.6MHz,  and that it needs to output HF, or it won't work. Is 15KHz to 20KHz considered high frequency?
What do you think about this Itsu? As the rest of the system needs to be tuned to the grenade. And you are about to make further tests of your grenade.

  AG:
    I think that the scope shot I posted is NOT ambiguous, and no one else has shown anything like that, as yet.
   Remember I am on the track of what is truth, and what is BS, not just some untested opinions. If what I mention is really wrong, as Max thinks, (and he then makes a big point of it), of just how "completely wrong" I am. I'll be the first one to change my opinion. I'm not trying to make a point of anything. Trying to build something that WORKS...

A fragment from conversation with Sergey Stalker
A gradient coil is a high-frequency resonator that operates simultaneously at several frequencies that are multiples of a half wave. It is also a capacitor plate in relation to the antenna.
I have a 15.6 megahertz gradient coil frequency, antenna is at the same frequency.
Tesla tuned to antenna at a multiplicity of 1.5 megahertz with a little offset. Antenna - a top capacitance for Tesla coil.
The antenna wire coiled into a spiral emits at 15.6 megahertz.
Shnyaga is optional, this is a mirror for the antenna wave. Often a connection of wires of different diameters is sufficient.
This is only important when using a kacher to modulate high frequency. If the circuit is a controlled Tesla coil, then the effect of the magnetic field (from gradient coil) is not required.
Everything starts with a gradient coil and is built to match it. Antenna to match the gradient coil,
Tesla coil to match the antenna. Push pool to match the gradient coil.
If the gradient coil does not work - there is no HF spectrum, then nothing will come of it, just rewind.
Grounding through a diode to the cold end of the grenade (cathode to the ground).
Tesla coil also grounded (directly).
The diode does not need to affect the operation of the coil, it affects the operation of the capacitor formed by the coils.
In relation to the gradient coil, the diode is located in the current node.
The collision of magnetic fields creates a diverging wave from the center of the conductor to the edges, and the process of interference begins with the formation of the RF spectrum. The frequency at which collisions occur is neither dependent on the load nor on whether the ends are closed or open. This is not LC resonance, so it is convenient to tune everything to match it.
I called it magnetic resonance for myself.

Q: And if so, which magnetic fields are colliding? Gradient coil’s inductor and the grenadeitself?

In the grenade itself, from two counter wound bifilar coils.
Q: or "halves" of a grenade?
You can also call them halves.
First, gradient coil is made, its magnetic resonance determined, then we look at whether it generates
a HF spectrum when shorted, if so, then it’s cool, if not - throwing the turns over the layers and see
what comes out, rework until it produce some HF.
According to the HF spectrum of the gradient coil, we determine on which frequency we will work
on - this will be the frequency for the antenna.
Tesla is built in multiplicity to match the antenna.
Push pool in multiplicity to magnetic resonance.
I called it magnetic resonance, since two bifilar electromagnets interact. This is not LC resonance.
The frequency does not change either from the load, or from the presence of closed or open ends of
the gradient coil. LC is sure to detune very far in such changing conditions.

I see everything here as true.

Dear Nickz,
Nothing is wrong with PP freq. of 15.6KHZ. it is workable.

Nickz and Itsu,

I found out why my device was tripping off: the pathway of signal from the drain of my controlled Tesla MOSFET to earth was not properly established. It was caused by when I was etching my prototype board for this build.
My oversight.
