Kapanadze Cousin - DALLY FREE ENERGY

[d3x0r]

Had a long runtime from 68kuF... 1:14... but at low output; a lot of apparatus for lighting LEDs


I had greater output adding a capacitor of any large size (more than 9nF; really more than 500uF ) between the grenade and ferrite cores... but I think that smoewhat de-coupled the ferrite and grenade.   Was trying to find the 90-100Khz resonance that's happening with a high current drive.


Also found that the signal becomes much noiser and starts to look like itsu's signal that's all ragged and spikey; Found that removing the incandesent bulb smooths out the signal a lot... but then if it's tuned for having that, the the ferrite core gets a brown noise component to it.


Popped another 555 timer, but the mosfet was remaininng cool at 2Khz and 150uS ontime; increased resonant capactitance on 25+25 coil so it's freqeuncy is about 6khz... was focusing on getting a strong resonant signal there with the mosfet driver...

but this 83khz ring back was found, and I don't know what that's cause by... was working on adding the cap between grenade and ferrite when I found just about any cap there increased output; didn't change the 83khz(?) think at that time I was watching other things.  I had the 555 tuned so it would generate some light on the incandescent, and the light improved adding a 80uF 400V aluminum foil type cap across the light.


And at the end before I over voltaged another 555; removing the incandescent would diminish the output to the LEDs and restoring the light would make the LEDs light more... probably relieving excessive pressure on the negative bridge side.


but adding the cap kinda decouples the grenade... and ends up doing all the work on the ferrite I think.

Hi Guyz

   magpwr,
nice to see you have built your grenade coil,   , and yes 60 winds is the first layer. You got that right.
The pic will help many out to see and measure the coil to get the same amount. but again wont matter if it's a bit of, that will mean you'll
have to find new resonance frequency and harmonics to tune correctly.
20AWG I used too. Mines in 210 uH.
Lets see how we all progress here I will also help out with some of the information on russian forum.
thnx for reposting some of the important parts and part for the harmonics alignment.

Nick:
Srry to hear about the Fets going up in smoke, hope you'll get new sets soon to join in again.
Btw what I wanted to point out is if you are still using the same toroids chokes with a thick winding.
Because if so, you'll have to change the wire gauge, to about 20 ..19..18 AWG (about 1mm diameter ) it will make sure your fets wont get hot instead of the choke.  20AWG is what I used for my ZVS and more.

Btw guyz I see some of the complete schematics posted here And even on Russian forum about the grenade coil  shown not to be in  the right direction of winding. the 1ste - 3de and 5th layers are the direction it should be but the other 3 layers are not. specifically for that schematic.
just wanted to point out  although  kacher is  and Bifilar are good in direction that is in first pic ,

2nd pic is the one Ruslan used and can be seen in one of his Vids, the propper way of winding.
This is to just point out for help but I know we all have the right direction of winding via the Kapanadze aquarium grenade coil winding
and with the help of Ruslan's latest videos on the windings.

Will be uploading what I have been up too.

I have removed my coax windings around the 2x 25 turn coil and wrapped 25 turns of 1.5mm² solid copper wire instead.
The inductance of the 2x 25 turn coil stayed the same 87uH but the resonance of this coil in combination with the 0.47uF cap
went from 26.5KHz to 47KHz!!??.

This caused the nano pulser repetition frequency also to go up to that frequency as it is synced with the TL494, which was to much
and things (DSR diode, little toroid) were getting hot very fast also because the impedance of this extra coil is not the expected 50 Ohm.

By adding another 0.47uF cap parallel to the first one, the resonance frequency went down to 32KHz so this capacitor is not ONLY a coupling cap
it also influences heavely the resonance frequency of the 2x 25 turn coil.

I have no explaination why the resonance frequency went up with the same inductance, as the extra capacitance from this extra coil should have
caused it to go down in frequency,  Right?. 

But this in combination with the extra 0.47uF cap parallel is dampening the resonance heavely and the max pp voltage went from 160V to around 90V,
(or are we talking mutual transformer coupling losses here?).
So i don't think this is the correct route (the extra coil) to follow to get the nano-pulse delivered to the grenade.

Hi Itsu. Yes, if the measured inductance of the 2x25 has not changed much (with your extra coil in place and everything connected)
you wouldn't expect the resonant frequency to change too much, but it also depends what is connected to the extra
coil and the grenade coil.  Also impedances/loading will probably change when your pulser circuit is active as opposed to
when it is switched off. It may possibly be a difference between resulting impedances when everything is switched off,
and when everything is switched on and running.

Since your resonant frequency has changed for the series resonant circuit, indicating an impedance/loading change
to the series resonant circuit from somewhere, this impedance/loading change will also reflect back to the
push pull driver and change the load it is seeing. This would result in different voltages produced in the series
resonant circuit. Yes, when the three turn winding is connected through one or two 0.47uF caps to the 2x25
winding, the total cap value is definitely setting the resonant frequency of this series resonant circuit.
It is not meant as a coupling capacitor in this arrangement. As you know, in that particular arrangement you definitely
want to tune the push pull frequency to match that resonant frequency for the resulting max current through
the 2x25 winding, and max voltage across it. MenofFather must have been referring to a different circuit arrangement,
I would guess.
All the best...

2. Does anyone can understand from video what is ruslan's katcher circuit?
3. Ruslan during video tunes his katcher at 3.1MHz with out the antenna connected. When we connect the antenna part won't that frequency become lower

Hi Jeg. It looks to me like Ruslan is demonstrating a common Kacher Brovina circuit arrangement.
See the attached schematic for what I think his circuit arrangement is. Appears to be close to this anyway.
Yes, the kacher frequency will become lower, but Ruslan has mentioned he runs his kacher at about 2 MHz.
With the big 'antenna' coil in place his frequency may drop down to about 2 MHz. Spacing between the
'antenna' coil and the grenade coil will vary the loading on the kacher. Varying this spacing will also
probably adjust the resulting kacher frequency somewhat. The two diodes may be two back to back
zeners for over voltage protection on the transistor base.
All the best...

my old transistors oscillated about 1.2Mhz... nowhere near 3Mhz which would be like half the winds at least?


I got new 555, and irfp250 (no haven't got a good part for that)
wound a new secondary that should be near 49m (48ish) maybe a little shorter, but with 2n3055 I'm only at 800Khz... there is a at least 3x frequency on top of it.... I dunno these other mosfets don't work as well
http://www.nxp.com/documents/data_sheet/PSMN7R8-120PS.pdf have to start again from scratch I guess.
Wound the tesla on a 3 3/4" roll... so it's w/h is more like 1:1; sawed off my old secondary, so I can stop getting interferance from that... if I touched it it would kill the whole oscillations and I'd have to start again.
