Kapanadze Cousin - DALLY FREE ENERGY

Hi yes it's sort of all going, some where.

I recently made a Tl494 driver module as per circuit posted on lists posted here, I first noticed the Pots scan over a very wide band width, a few hertz to a few hundred kHz I altered the 2.2k in series with a 15k and  the 22k pot I had to  jumper with a 4.7k in order to cover the 17khz range, it's Farley stable to a point but can drift 20 or 30 Hrtz, I'm not to happy with this drift as it needs locking to the earth's resonance.

I have made a device that's crystal locked to this frequency that's a simple dial up setting, using a cd4060 a xtal and 3 cd4522 down counters and some cheep BCD switches, that do the job, it needs injecting into the TL494 earth side of the timing cap, instead of going to earth link,  the other thing here is the wave drive switching circuit has to be a square wave not a sine as it's not possible to have harmonics easily with sine wave, so be aware of this as some of the Russian speakers have mentioned this little gem including Wesley.

Also the Nano Pulse, does this pulse have to be set to the peek of the grenade resonance, centre of its sine wave ? ( as this is the most useful part ) so what ever that frequency is set to would determine the nano pulse's repetition rate, would it not ?

From my understanding, the pulse should be on top of the inductor/grenade voltage or current peak, so there should be some room to manoeuvre (±90°).

Nick,

sorry to hear you see no improvements, it is where most of us got stuck.
I just yesterday finished building my new nano-pulser so i can swap it out for the kacher.

I like the 1.4Kv pulse, but i am not satisfied with the gate and drain signals which look terrible.
I think when i can clean those up then the pulse will be higher and/or with less input.

Below first screenshot shows the present 1.4kV pulse i got with 260V on the drain, and the second screenshot shows the terrible gate / drain signals.

In this second screenshot, yellow is the drain voltage, green the drain current (500ma/div.) and blue the gate signal.
Pulse repetition frequency was set to 10Khz which causes the input to be 24V @ 1.5A.
When increasing this p.r.f. to the max. 23KHz of the onboard VCO, it increases the input current to 3A.
By the way, this 2e screenshot was taken with the drain voltage set to 130V!

hi itsu,

I have seen your nanosecond video.

If you don't mind me suggesting something related to circuits.

Base on video-There is no need for resistor to mosfet gate if you are playing with nanosecond pulse.The resistor can be bypassed.
The resistor will create slow rise time in nanoseconds due to mosfet gate capacitance

Decoupling capacitor eg:tantalum preferably of low ESR is highly recommended for mosfet driver for nanosecond generator.

If using breadboard do take note of spacing between gaps because after 1kv in nanosecond this distance\gap would decrease the efficiency as the frequency goes up.

---------------------------------------------------

Applying nanosecond pulse over antenna or via coaxial cable once right frequency is set will cause bulb to go dim once power is disconnected from nanosecond generator/hv supply.

This part to date i have not figured out why this pulse is able to meddle with the L/C resonance.I am Lost since this info isn't available to us....

Normally we go for L/C resonance to get bulb lit to the max where possible.But in this case what i am trying to say the bulb should go out once pulse is gone.Like said i am lost.

----------------------------------------------------------------------
The current 1.1kv nanosecond i've thrown on the floor for public to see is able to be powered easily by a 9volt battery."If you know what i am suggesting as seen in Akula video"

Magpwr,

thanks for comments, they are allways welcome.

To my understanding, the nano-pulse is being generated by the DSR diode (KD226D), so the MOSFET and its driver are not running at nano second speed.
They run presently (video) on 10Khz repetition frequency generating a 200ns wide pulse, therefor i don't think they are that critical, however we
do need/want a fast/clean on/off switching of the MOSFET.

The present UCC37321 driver should be able to do that, but it might be its to far away from the MOSFET and the socket it is in might have to much stray capacitance.

I will try to modify this by putting this (inverting, so needed for the correct drive pulse polarity) driver on 5V and adding an additional UCC27511 MOSFET driver
directly attached to the MOSFET legs.

I have a 10uF low ESR tantalum across the driver plus/minus leads already to supply for the source and sink currents needed by the MOSFET gate.

  Itsu:
  Thanks for your reply, and your video showing the nano pulser.  I'll be patiently waiting for your further results, once it's connected up to the grenade.
 
  I'm still looking for an controllable PWM Tesla coil driver board, with frequency control also, which can be used instead of my current Kacher driver.  I have not found one yet. If anyone does see one that's available, please let me know.
  I'm too far into the remote jungle area to be ordering all the needed part to build it myself. And if it doesn't work as planned?
I'll have no idea how to fix it.

  Too bad we can't just buy the right driver boards...  from Oleg, or the "Boys"  Maybe it will be possible at some point...
  If only T-1000 would not be too afraid to just ask them.  The worst that can happen is they can say no. But, if they say yes???
