this plasma output is only from the end of secondary wire which is 0.18mm thick. After I connected some piece of HV cable to this end, plasma "laser saber" is lost.

Plasma is caused by electrons leaving metal at high speed. For a number of reasons this happens easier at sharp points.

any chokes placed on both positive and negative connection to battery prevented oscillation of circuit.

Woopy also had high frequency AC coming out of battery. Putting capacitor across battery may shunt AC around battery.

@ boguslaw

How many turns did you use in your coil? It usually takes a lot of turns to get plasma.

chokes

@ Boguslaw

Also I found it strange that any chokes placed on both positive and negative connection to battery prevented oscillation of circuit.

Welcome to the club, i noticed similar problems when using chokes, see my video at the 4:19 minute mark:

The solution was to use a 0.1uF ceramic capacitor across the battery terminals.
However 2 went up in flames since then (i think they are rated 50V), so there is considerable
voltage on those battery terminals so now and then (especially when using grounds in your circuit).

[boguslaw]

Thank you Itsu ! This is indeed exactly what I found too. In the end I removed a choke from negative connection to the battery, but now according to your method I will try 0.1uF ceramic capacitor. I hope it will work limiting ripples because my idea is to power kacher from AC to DC converter (transformer + diode bridge + filter capacitor) with ISOLATED GROUND - this is very important to me.

@ Guruji
I recommend using boguslaw approach of getting the oscillator working first and then adding other parts.

@ boguslaw
Congratulations on your success. You seem to have great performance.

Thanks Xee2 the thing I don't know Boguslaw schematic.
Yes it seems to get oscillation is a problem.

[Guruji]

Attached is my schematic, based on simple kacher I found on overunity.com thread. You can delete modulator part. U5 is when secondary of kacher coil is connected, U4 is connection to primary. Primary is 5 turns of 2.5mm^2 wire, secondary is about 1000 turns of 0.18mm diameter enamelled wire.

Thanks Bogus for the schematic. It's a bit complicated. I think I will continue to try on woppy setup and see.

Simpler version, just Kacher.

Ok this is nearly the same as I've built ok if I would not succeed on the other I will do this.
Thanks.

Thanks.

Yes,I placed BA159 diode here to stop oscillations reaching source battery but it didn't helped.

So you managed to get oscillation with woopy setup?

[boguslaw]

So you managed to get oscillation with woopy setup?

if you mean oscillations reaching battery then yes, fully confirmed with simple test device (one turn of wire connected to AV plug and led). However I didn't tested the whole woopy circuit.I was interested in range of RF field around device for safety reasons. However I think depending on wire length from circuit to battery you can get more or less energy in the coil around battery.
It all depends on integer division of wavelength produced in circuit, see ? Exactly what Don Smith said.

I cannot make video but with proper adjust of kacher you can check wave nodes on secondary and even with so low power placing check device(with AV plug as described) will turn of the plasma output on top terminal.

I remember that first such experiments were performed by Nikola Tesla around
1890. Also gyrator circuit is similiar.

@ Guruji

One problem people have is not getting primary current going in proper direction. Always try reversing the leads of one of the coils when trying to get oscillation.

Yes,yes yes ! Very good advice, I stumbled upon that yesterday and it force me to check all board

I found something maybe related to woopy experiments. Conductivity of water (or ground in woopy case) for radiant energy.

37 turns winding around the 12 V battery

Inspired by Woopy's experiments I did some tests with my latest Kacher. It is all about a 37 turns winding around the 12 Volt battery. See the attached photos and drawings.

Connecting the Kacher to earth ground gives me a headache:

A) I found two points in the Kacher circuit which can be grounded, the end of the secondary or the minus rail.

B) Electricity (induced by the radio frequency in the battery) comes from the coil around the 12V battery, goes through a fluorescent tube (and or through an AV plug with LEDs), and has to be grounded eventually.

Ground A) and B) can not be the same ground. Therefore I tried the "big metal mass" as a second virtual ground. Also the body can be a virtual ground.

All works somehow without any ground connection, but the tubes or LEDs become brighter when specific ground connections are made.

It also looks like a tuning problem, because moving a hand near some points in the circuit increases the brightness of the tubes or LEDs. Actually touching some bare wire or bare connection often kills oscillation. But the body can be a good virtual ground at the good ground points. (Attention, the "touching experiments" are not recommended with a high power Kacher.)

12 V battery (instead of power supply):

I now use a 12 Volt battery, which is much better than a power supply. My power supply tried to suppress current backflow from the circuit (from the back EMF of the primary) which caused strange effects, like the display of the power supply indicating a higher Voltage than set when the circuit was running and oscillations from the power supply being induced into the circuit.

My Kacher shows different frequencies depending on what I connect to the secondary:

When the secondary is left open, I get about 1400 KHz (but even a short wire like an antenna lowers the frequency to about 1200 KHz).

Connecting the end of the secondary to ground or to a big metal mass produces about 980 KHz.

When I put a CFL tube with a 56 pF parallel capacitor from the secondary to the minus pole I get about 500 KHz. Using a 160 pF parallel capacitor lowers the frequency even further and causes up to 1 Ampere power draw. (The parallel capacitor is very important to light the CFL tube brightly.)

The winding around the battery has no effect on frequency, no matter what I connect there.

Future tests:

What I want to do is lowering the power consumption of the Kacher as much as possible. Then I want to try harvesting all the stray radiations showing up in and around the Kacher (like around the battery and around the coil). May be a "copper pipe with a slit" in the centre of the secondary to take away the energy, like with the coil around the battery.

Dragon/Lenz posted that ground connection is important. At the moment I guess that the Kacher should not be connected to ground (should freely swinging), but the stray radiations should be led to ground when doing something with them.

I like the Kacher with little power, because one sees the grounding and tuning problems more clearly. Pumping 24 Volt and many Watts into the Kacher gives spectacular effects but drowns subtleties in the strong radio emissions.

The two interesting places in the Kacher are the secondary and the battery. There the strong radio frequency emissions happen. When connecting the end of the secondary to a "big metal mass" the radio frequency emissions also happen at the "big metal mass" and become weaker at the coil.

The unproven speculation (inspired by Dragon/Lenz): by exciting the ground or the air some additional energy (charge, electrons) can be harvested.

Greetings, Conrad

On secondary how much resistance wire there should be?
Conrad thanks for sharing
Thanks Xee and Boguslaw.
