It will require rather long discussion to show how these systems work (or how I think they work).
It is better not start it here.

I disagree.  Any additional info regarding operation or underlying principles, even if some is speculation, could prove helpful to replications.

You looked into Dally's last setup ? There is push pull driving load and a coil connected in series and subjected to Tesla coils fields. Isn't it same as we have here (not taking into account fancy coils construction) ?

Vasik

If this is the set-up in the short video/translation using two TC's, then yes, but I have only seen that one video and translation.

Do you have additional info or schematic regarding that configuration?

   It's hard to try to figure out how this might all work, when it has not worked for any of us up to now. We can speculate, at this time, but that's it.
   What I feel will happen, and will come as no surprise to me, is that the best resonant points and values will not be where we think and calculate that they should be. And after all those great calculations, and precise tuning, all that will be tossed. And the best results will be found where the tuning by hand will indicate, without following any calculations. Like Geo and I have had to do. Geo does not even own a scope, until lately. Yet, we have not hit on it either. But, have come closer than following any of the proper calculations. In any case, it's good to experiment, as there seams to be no other way. Remember that each self runner shown is running at different frequencies, different outputs, etc...using different tuning methods.
Those are my findings, and I'll bet Verpies a cheeseburger, that that is what will happen. I wish to be wrong, but...

   P.S.  I agree with Vasik, that theoretical speculation will get us no where. There is over 10 years of proof, about that. Yet, most people will not go through the trouble and expense of building something that none of us can get to work, as yet.

This topic already more than 60 pages. It is difficult to find something even for me.
Only very devoted builders will read it through. Theoretical discussion will multiply number of posts.
I probably will have my bench soon, I will make a thread there.

Yes, there is a schematic in the translation pdf.

I see this is not your thread yet ( moderator)
However I can remove ( or certainly modify to zero)

You mentioned dangers with magnetic fields
Yes I am ignorant of topic
However MRI comes to mind ?( are you certain it is magnetic?
Not other? X-ray or ??

Chet,

Strong EM field definitely a sign of danger.
Even official science acknowledge this e.g https://pubmed.ncbi.nlm.nih.gov/27012122/ or https://www.degruyter.com/document/doi/10.1515/reveh-2021-0038/html
However, there are other less known and not well researched fields
usually accompanying  EM field. This is quite complicated.

In my studies I found that it is difficult to build FE device, but much more difficult
to build such FE device which will not damage everything around.

This topic get very low attention. Most people believe that there is no such thing like FE, so there is nothing to discuss
or worry about. Silence also beneficial for people not interested that such technologies appear.
Since research usually made by amateur researchers, they usually not aware of dangers, so easily hurt themself.
No need to send MIB's after them :)

   I have spent many many hundreds of hours being and working  right next to my device. However, once it is working right, and self running, it probably would be good not to run it near too any Pc, a Tv, mouse, scopes, or people, etc...

  I never felt anything to write here about, concerning health hazards from these particular contraptions.

  The only one of us that has mentioned any thing about having been affected by these EM fields, is the Lituania tests, where Wesley fell asleep, when they were lighting the 1000w bulb, with their yoke device.

  I only feel good when I work with the yoke/grenade/kacher devices.  I'll believe that it may be harmful, when I see it, or feel it.
  It may be more dangerous being next to this computer, it's router, cell phones, cell phone towers, or being near any of the older CRT Tvs or monitors, for hours each day.

This is from a cold plasma in a reactor I built some time ago for making methane from water and carbon dioxide, it is the same as an RF burn so be careful.

Itsu,

What length did you use for the grenade wire and did you wind to according to version 2 in Vasik's documentation thread (I seem to recall you stating you had to rewind/correct part of your grenade)?

Also, did your winding calculations end up being similar to Vasik's winding calculations (as in his documentation thread)?

I thought your grenade wire length was longer than Vasik's...

It is all in the topic, see what I mean "difficult to find" :)
Itsu made first version with thinner wire as it wasn't clear what wire need to be used.

Vasik,

I did go back from the beginning of the thread, but in the end, I was unsure what wire and length Itsu ended up with regarding his final coil.  As well, he mentioned having to correct some windings, but he did not state what those corrections/errors were.

Also, it seemed his insulation was a bit thicker than yours and I wondered if that changed his calculations/measurements very much compared to yours.

I am considering winding a grenade, and wanted to construct one similar to Stalker's, yours and Itsu's (if they are indeed all similar).

PW,

Itsu will comment what he changed. For myself I just took 37.5 + 1m for leads, wound it first
on 50mm tube. Inductance, number of turns and width all matched very well with calculation (screenshot attached there). After that I rewind it as grenade. I had to make 3 or 4 attempts with reverse turns to get inductance right, otherwise it went ok, thanks to Itsu's previous work.

Vasik,
When you wound layer 1 and 2, did you run the straight wire that connects those two coils between the two layers or run it through the tube?

i had to look up some things for my self .. :D

My present Grenade L5 coil is 37.5m + 1m connection leads and i wound it according to version 2 (so return to begin after each layer).
This Grenade was spot on with the calculator, not sure what Vasik's Grenade data is.

I had to rewind the Inductor L4 (¼ = 9.37m connection leads) as it turned out it was wound the wrong way, so i needed to correct that to comply with the winding directions.

Did you lay the straight wire connecting layer 1 and 2 between the layers or run it thru the tube?

No aluminum on the core?

Itsu,
I think you right, will check later.
I have 10 ohm 2W resistors and they are just a little warm.
Vasik

I tried with 5 ohms and current shape stays the same only amplitude decrease.
Based on scope traces I come to conclusion that actually my push pull transformer get saturated, not current probe.
This is quite unexpected result :)

Vasik

PS some more traces, top - gradient coil current, bottom - inductor current, inductor voltage, gradient coil voltage, L2 voltage

Vasik,

right, but if your push pull transformer (yoke in my case) is saturating, would then not the Inductor L4 current show a similar "moustache like" signal?

Why is the Inductor L4 voltage lower in frequency (sc 3) then the Inductor current (sc 2)?
Itsu
Itsu,

I tried to simulate yoke setup with E core. L1 and L2 located on one half of the core and L3 on the other.
It could be that only part of the core where located L1 and L2 goes into saturation.

Inductor L4 voltage and current should be same frequency, they just have 90 degrees phase shift and so it might look like they are different. Both screenshots taken with same settings.

Hmmm,   looking at SC 2 blue trace, i see ~12 periods over slightly more then the screen = ~260us = 21.6us/period = ~46.3KHz
   
Looking at SC 3 blue trace, i see ~4 periods over slightly more then the screen = 260us = 65us/period = ~15.3KHz

Itsu

Itsu,

but SC3 is gradient coil voltage, not inductor voltage :)
I have inductor tuned to 3x push pull frequency.

Vasik,

What sort of load do you have connected in these captures?

Your non-sinusoidal grenade current waveforms look like current to the load thru, and as, the bridge rectifier switches.

This is without the 28T, correct?

Vasik,

In reply#1489, Itsu posted captures of grenade current without the 28T.  It was a fairly clean sine wave.

He stated that these captures were made with the bridge, smoothing cap, and 25W bulb load connected (100V @70ma).

For these tests I have 40W halogen lamp connected as a load without bridge rectifier/dc capacitor.
L2 (25turns)  is connected.

yes, without L2 I also get clean looking signals, but they are weak, 40W light not even glowing if I use 3x push pull frequency tuning for inductor circuit. With 1x frequency tuning output signal stronger, but then it is really difficult to tune both coils in resonance.
