Kapanadze Cousin - DALLY FREE ENERGY

Any opinion if I do right?

I have add more wire to my kacher to tune it to around 600KHz ( the best scope result for grounded granade)
Unfortunately with more wire the consumption went up. It takes now around 5A at 18V  (before it was taking only 2A@24V @1.8MHz)
I think if I will properly tune Primary to secondary coil it might drop the consumption (I hope)  I need to find right cap for the primary coil. The problem is  I am not able to check the inductance of the secondary as it is over 20H (max on my LCR meter), so I guess instead of calculation I wil use my SG and oscilloscope to find the natural resonant frequency of my secondary coil and tune my primary to it? Does Brovin makes it more complicated than that?

Thanks

"over 20H "  are you sure?   I have severall Kacher coils, one with about 900 turns,  but it only measures 9mH.

Not sure how you want to tune the primary to this secondary, if you use the simple Kacher setup as can be seen in the Ruslan diagrams.

Guess you can find the correct tap for cleanest (collector) signal and lowest power consumption, and/or slide the primary along the secondary
to find a sweet spot there.

I would almost dare to say 48/24/12 is magic.
64/32/16 doesn't really work as well
when I did the singlefilar magnet wire version; I stuck to 48 proportion also... and with the current system it is the best...


----------
used 12/12 turns bifilar to drive fullscale air core... it doesn't have good resonance itself... and it's only a tiny capacitance to make it resonate...


it has a very sharp peak that has some resonance... but would have to be a higher frequency signal.... and the output is very slight

  You keep mentioning Kapagen coil, led bulbs, and different set ups.
  This thread is for Tk/Akula/Ruslan type of replication.
  You say that you have a 3 inch yoke?  And a Mazilli crt, and a grenade coil, but, aren't using them.   
 
   This project here, is not about making an inverter (like the kapagen) as it is not a self runner, and never was one, either. Nor about Joule Thiefs, Joule Ringers, or other oscillators of low output systems.
  So, you've moved on...
 
  I would recommend you follow along with what we are doing here, if interested, and make a proper Ruslan/Akula type of replication.
Otherwise, if a self runner replication is what you are looking to build, you may just be wasting your time.
  Ok, enough said.  I won't bother any further.

Whatever you're still stabbing in the dark, not knowing why it would be self running.


I don't have close enough approximate parts to make a closer replication; but I do suspect that this is pretty close.


A Kacher's a JT. 
I'm interesting in what makes it tick.

Look - kapagen coils....   I'm soooooo far off base....


You're right; we're not looking to make an inverter... so why use all the peices that only resemble inverters?  like ferrite yoke/toroid cores?  Even if it's elongated it still only behaves like a closed toroid.

like I said... 'been there, done that, bought the shirt and burned it'...
----
But with these new coils I'm starting to see something.... if you are still lost, just stay lost and ignore progress.

Edit: FUrther; with appropriate resistor selection, you don't need zeners.

Hi Itsu, you are right, It is weird. I have around 1000 turns of 0.3 wire.  When I check it- I connected one end to the start of my secondary and the second end of my LCR meter to the very end of antenna . Now When I am thinking about it I should check each piece of my secondary separate and sum them ?(Long coil + what's on ferite rod+antena)  In any case my cheap meter shows from mH up to 20H  and it was showing  that the value is more than  20H.

Thanks,
Jan
