Thanks for the link of Сергей STALKER schematic you posted. But as far as I know, the grenade coil configuration of STALKER differs from that of Ruslan/Akula's. For example the length of the induction coil from the STALKER is L/4 but for Ruslan/Akula's the length of induction coil is L/2 where L=37.5m . And the way the 6 layers grenade is wound also differs from Ruslan's, as is shown in STALKER's winding schematic. Currently, for the configuration of the grenade and its induction coil, I would like to focus on the Ruslan's configuration only. And those questions I asked are for the Ruslan's configuration rather than STALKER's.

Hi !
just my 2 cents:
For me the STALKER circuit and STALKER grenade details are one of the best roadmaps since a long time.
These make really sense in my eyes except the polarity marking of two capacitors (is there a "+" sign?)

Regarding the Grenade:  This winding directions is what is correct  -  look twice before winding  -  follow the flow of electrons...
(my personal measurements and findings from my own coils confirm this - but still could be wrong, since i do not have more out yet)

Regarduing the induction coil: i suggest to use two layers L/4 first and L/2 later. It is easy to dismantle/rewind the induction coil having 2,3,4 layers and7or different lengths....

Good Luck and don´t expect to succeed on first try - keep on....

   The problem with using Stalker's latest circuit is that he is not showing it self running, as yet. Nor several of his older TL494 circuits and Kacher interupter circuits, either.  Until he does we can't tell if those circuits will work as well as Ruslans, or not.
   The short jumper wire that connects from the grenade's inductor coil to the grenades output coil is not a small detail, which is not present in Cepren's latest diagram, either.
   However, that latest design by Cepren shown on his video is the best description of how to build the circuit, with most of the important details, except for showing just how to properly tune it. Although he is not using the tv yoke but a square ferrite core instead. Hopefully once he gets it running, that will show that the special yoke cores ae NOT the only core that will produce a self runner.

   Hoppy:  I now have most of the parts to build a new TL494 circuit board and fets driver circuit. The same as Ceprens latest TL 494/fet driver circuit.
   I also bought a new 12v, 7aH battery, and a new multi-meter that can read the frequency, as well. As my analog scope does not show the readings, and requires that I do the math. Which, is Not my thing...
   I'll be working on this new circuit starting today.

   Geo: Any luck on your feed back circuit???
   
    Apecore:  How's your new set up doing? Any luck, so far?
    A short video of your new circuits would be good to see.

    Guys: Thanks for focusing on the Akula/Ruslan type of devices.  I know that some of us do appreciate that , so that we can further progress to see some actual self runners built by our team. And, so we'll possibly be able cooperate with the Russian builders, also, for a change. Like in the US/Russian space missions.
   

Can you upload it to overunity.com ? I cannot download it with chrome browser.

No I can't do that it's too big and you need to know how to do it yourself, but you can down load it your self, get the page up go to the top line and crome will drop down the black line with a down pointing arrow click it and it will down load the PDF
or you can click print screen on your key board then down load it to your msprint program and save it that way.

You do have a PDF read program on your computer if not down load a valid one !

That's good news Nick. What will you be building the circuit on?

Hi, all

Today I finished the 18.75m four layers induction coil. Did a quick testing for the resonant frequency using the schematic attached from MenofFather.
And here are the results. Note the 1.7MHz frequency.

Good job! According to Sergey he says 3.34Mhz/23.5Khz (38 meters grenade / 19 meters inductor).
I've also seen on some russian pictures  written on the PVC pipe 1.667  Mhz  3.34Mhz/2 = 1.67Mhz .. so you are in that area.
With my tests I only seen an 150mA drop from the Push-Pull @24Volt wile tesla was in sync and no effect on the incandescent bulb.

could it be the wave or harmonic length he is using ? guess!

Yes nice work but can i suggest you do it a different way ? just concentrate on the main grenade winding and the 1/2 wave secondary and forget the static winding. Find the current link frequency between those two windings with your scope and frequency generator using a pass through current to voltage toroid device you can wind yourself also on one of Stalkers vids. All this is basic Amateur Radio know how thats why most Eastern Europeans like Russians and others are good at this hobby.

Anybody is able to download Stalker files from here : https://yadi.sk/d/8rY1WiX6vZSnw ?
