Kapanadze Cousin - DALLY FREE ENERGY

Guys, take a peek at this video:
https://www.youtube.com/watch?v=-UCqosiunTc

He is driving the lamp from the grenade coil using only the power input from the Kacher and a ground wire, nothing connected to the induction heater coil, no yoke or push-pull circuit.

Here are translation notes from Russian:
The bulb there is from the fridge and is 220V 15W. When turned on it is not clear if it was fully lit, probably gives output of 10-13W.
The Tesla coil is made from approx 0.75mm diameter wire and is not including tuning choke between "antenna" (top load) and grenade coil.
The Tesla coil is driven from katcher which got 17V from power source and taking 1.28A (21.8W) when bulb is lit.
Also he mentioned about avoiding touching HV wire as it burns fingers instantly.
When there was much more turns on Tesla coil it was ionization from all grenade coil, including from the its output. But that did not change bulb brightness so when there are less turns and the bulb lit that is indication of running close to resonant frequency.
Also in his case the attached ground wire does not have almost any influence and it works with it or without. But as one of his friends was on demo in Kapanadze aquarium box, the thick ground wire was heating up...
When he disconnects grounded side wire from the bulb is still lightly lit but when touching it arcs over. The bulb brightness also noticeably changes when wire insulation is touched.
One important thing - the Tesla coil and internal connection from first layer of grenade coil must have common ground.
The most tricky part there is to tune Tesla coil as winding and unwnding is only one option and it takes lots of time and effort to tune just like Ruslan said. The balance need to be found between inter-winding capacitance and amount of turns of the coil. The interwinding capacitance should be minimal as the tuning is heavily influenced when the top load is attached.

P.S> In his second video https://www.youtube.com/watch?v=FHIW8bvsRK8 the moulated Tesla coil without step up voltage gave very weak signal and he was not happy with the setup and wanted to improve Tesla coil output...
And why katcher circuit with feedback cannot be used there - https://www.youtube.com/watch?v=gdVYofNe5zY The CLF indicates wave power loss when going from Tesla coil to top load on the grenade coil

Please clarify on what you refer to as - "close to original as possible".

The circuits you seen in Ruslan videos are designed by Oleg and the same circuits was shared in forum. So if you make them on your table that will be same electronics as in original setup.

Guys is anyone here that bothered to measure the exact length of grenade with 48T first layer at 5cm diam. tube? I know that i take you way back but really have you tried to calculate it? I started to wind a new grenade and i don't know what is wrong. I find out that total length is 29m. To reach 37m i calculate that i need about 68T first layer. Is that true?

Hi lost_bro,

My current understanding is that the grenade coils natural frequency is divided by 4, so if it is 8MHz, then the Kacher frequency is set to 2Mhz. The test (as I understand from T1000) is that this frequency relationship is optimised between grenade and Kacher so that a small say 25W bulb connected to the grenade output, is lit to the highest brightness without the PWM powered-up. The PWM is then set to drive the yoke at either a 50th, 60th or 100th of the Kacher frequency, which would be 20KHz in this example using a division of 100. The Tesla inductor coil is also tuned to resonate at 20KHz with its series connected cap.

The question you ask about C**1 is exactly what I have been pondering. My guess is that the value of this capacitor is for fine tuning and should be chosen to produce maximum voltage across the output lamp load, once the condition above has been established.

There are clearly questions about the tuning procedure that need clarification from someone experienced in the art.

Good day Hoppy

Talk about multiple degrees of freedom!!!!! It's like the needle in the haystack syndrome.

OK,  Please find attached a *redrawn* diagram. Electrically this is the SAME schematic, It was only redrawn to show fundamental layout and help with circuit analysis.

Just stating the obvious.

Yoke output winding is effectively shunted by both C**1 & C**2; with a Yoke & Grenade series configuration.

Note that C**1 & C**2 capacitively couple both ends of the Grenade coil to Earth ground. Under the *right* conditions I could imagine some sort of 'Rubber Band effect' where C**1 & C**2 serve to isolate/propagate recirculating currents within the Grenade coil.

Regarding C** notation, usually both caps with same notation would be understood as both caps with the same value............... A 'Rubber Band' would be equally elastic on both ends.

Assuming for a moment that this device is for real; I envision a curious effect taking place and one that requires *extremely* precise tuning.

'AL' values for ferrite cores can vary for the same core between various batches; so just copying a N1/N2/N3 ratio on the yoke core will NOT cut it (relative values for ratios remain the same, but absolute values in relation to Cap. values will change inductance).  Not to mention the detailed idiosyncrasies of hand wound air coils and their integration in a multiple coil system.
I would hazard to guess that for the same device, just swapping out yoke core would require retuning of the entire device (N1/N2/N3 ratio & cap values).
Needless to say that *each* device will require hand tuning and each device will be unique as to it's final frequency spectrum.

Just my opinion.

Please remember that opinions are like a$$hole$:  everyone has one

take care, peace

"One important thing - the Tesla coil and internal connection from first layer of grenade coil must have common ground."

Well this statement completely contradicts 'Ruslans' schematic.

Note that C**1 & C**2 capacitively couple both ends of the Grenade coil to Earth ground on the Ruslan schematic.  NO common earth ground there!

You can't have it both ways..............

take care, peace

EDIT:  Ok.  technically there is a serial earth ground through the Yoke Secondary................ but it is not a direct earth ground.
