Kapanadze Cousin - DALLY FREE ENERGY

[verpies]

My scope tops out at 50 MHz so I know the waveforms are probably
borderline at best.  I sent in the smallest pulse from my BK pulse
generator I could make at a running interval near 100kHz.  Yellow
channel input 1x; blue channel on the base of the coil 10x.  Limited
the input to one volt and used a 50 ohm resistor for impedance match.

Your coil seems to have an intrinsic impedance that is very different from 50Ohms.
The zoomed scopeshot shows multiple reflections.  One of them will be from the unterminated end of the coil, but the other reflections must be from other impedance mismatches.  Perhaps you could use a non-wirewound potentiometer or rheostat to hunt for the proper impedance match.

I'm wondering if a Cascode type device might work for this.  I spotted a NTP8G202N
at Mouser I was thinking of trying.  Let me know what you think may do the job here.

Yes, the Cascode circuit will increase your upper frequency limit.
If you can afford it and want to have a versatile transistor for this and future projects, that will last you a lifetime, then I recommend the  BLF578XR or the BLF188XR.

The Q must be pretty good--notice how long the coil continues to ring after the impulse.

Yes, the Q is good, mainly due to not wrapping it in plastic tape and air gaps between turns.

When you look at your coil you should imagine pulses bouncing back and forth from its ends.
If I were you I would put my FG into single shot mode (or low pulse repetition frequency) and measure how long it takes for one pulse to reflect and come back (using the scope in single shot mode).  Using one sparse pulse prevents the superposition of many reflections arising from multiple pulses spaced too closely together.

For these tests, I strongly recommend building a low power picopulser based on BJT avalanche like Itsu did.  It is very cheap and simple ...and if you already have a ~100V DC power supply then it is super simple.  Ask Itsu for construction recommendations.

And because of this super transistor then we get free energy. Yes!!

No, a transistor like that will not make free energy alone but it will put you in control of the signal you want and will not burn up.

MR VOID !

Hi URFA. It looks like you are getting the 40W bulb to light up not too bad.
It is hard to tell what you are doing exactly without knowing your exact circuit configuration.
Is that a kacher driver? What was your current draw from the 12V battery? I can't tell from the video.


@T-1000:  I had mentioned that the tesla coil couples to the grenade coil mainly capacitively via
the so-called 'antenna' (top load),  about maybe 1 1/2 to 2 years ago or so in this same thread.
I don't think that is really anything new to anyone who has been following this thread.

void two of us asked URFA about the coils and how he came to obtain the winding details and so on  that would as i can see opened a rather large know how door but, you just told him what he had just shown us was not anything new ! unbelievable ! he could have got us out the shit with that feedback technique, so I ask again can you point us to this 'feed back know how' data ? please

could you exaggerate on this phenomena please
