Kapanadze Cousin - DALLY FREE ENERGY

[Jeg]

TK,anyone,

Just was thinking - we need to fire Tesla at the peak of the grenade's peak, right?  Can we avoid of using of more complex PCB and to go just very easy way made of :

"peak detector"....... made of a 1 diode, 1 capacitor and 1 resistor (second option would be together with OPAMP)  +  555 in Mono-stable configuration just to give one impulse to Tesla. (at the detected peak) ?

At a previous experiment of mine i had used a very simple and effective way for synchronizing those two waves. But instead of katcher i had used a mosfet firing at frequencies between 10KHz-300Khz. With some small modifications it can work with Katcher i guess. I used a one turn around the yoke core with some RC filtering to take the low KHz wave, and i drove it to a comp which gives a pulse output with a time duration which depends on the voltage reference on the other input pin of the comp. Then, i provide this pulse in a way as to open and close a 4066 switch. This switch when 'on', it passes from input to its output the HF driving gate pulses of a mosfet. A mosfet driver follows, to make these pulses a power ones, and then i drive the gate of the mosfet.

  Here's some more information on the previous Ruslan's Kacher and it's diagram. This is Ruslan's version that I'm working towards.
  Hoppy, notice the 0.15uf cap, and the electrolytic cap at the output (100v, 2200uf).  This video was from Jan 2015.
  The simple Kacher circuit below, is similar to what I'll be building up, also. I think that I already have most of the parts for it.

Hi Nickz
Thanks for the video. At what time of it did you see Katcher's drawing? Its only the grenade circuit there and this guy at 10:33!!!

Woopy uses some interesting drawings of Katcher with just one resistor from base to power supply. I wonder if it is more effective this way.

Hello Hoppy
OK, according to current knowledge, what is the supposed operating frequency of the 'Tesla coil Inductor RX' and the 'Grenade'?

I understand that the 'Karcher' Fres is  approx. 1.2MHz. ,is that correct?   And there should be a 100:1 relation between which two components (yoke & Karcher)?

Does anyone have a ball-park estimate on the yoke secondary output freq.?   Is this supposedly tuned with C**1 to the same Fres as the 'Grenade', or does this maintain a harmonic relation to the Grenade Fres.?

take care, peace

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.

Nick,

Thanks for posting this link showing the 0.15uF cap.

The complete circuit for test build - http://imgbin.org/images/26553.jpg

I also understand on trying out different parts and methods in electronics such as Mazilli driver is good for learning curve but to keep least amount of unknowns is best to stick with close to original as possible.

Cheers!

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