The Spark Gap was a common component to many devices back in the day, we still have some applications for it now.

The Great Nikola Tesla perhaps made the Spark Gap famous in his Tesla Coil:

We have seen this many times, many times in different application, circuits replacing the functions of the Spark Gap, some call it a Nano Pulser, a Nano Generator, Generator of Nano Second Impulse (GNSI), and many other names exist for such a technique!

One I am fond of, due to the openness of it, was Dally! Real name: Edward Lee

 His circuit was very well shown:

 

The function, to inject a very short duration pulse, at high Voltage, into a Coil that is in close proximity to Bucking Coils! The list of people that have used this is endless: Tariel Kapanadze, Ruslan, Akula, all used this technique many times

It is my opinion, that this is a method of Electron Paramagnetic Resonance, some have called this Ferro Magnetic Resonance, a few different names have been used!

I have build a few Circuits, copied from Dally, but my Nano Pulser circuits were too slow, only around 500 Nano Seconds.

   

   

It is critical to be around 10 Nano Seconds or less!

The above Images were given to me by a friend. This friend knows Ruslan Kulabuhov, has worked with him from time to time. Built Circuits for him.

Chris my friend, your DDT - diode drive transformer (big dark green ring) is very wrong. You need very small ferrite toroidal ring core with very thin wire. Also you can boost high voltage to any desired level simply by serialy connecting multiple Drift Step Recovery Diodes or DSRD-s. For boosting PEP or peak power level of your nanopulse you need connect DSRD-s in parallel and also in series and tune your HV storage capacitor for best nanopulse shape. Make it from several smaller HV caps. .

Also your Owon oscilloscope is little worth with his low bandwidth of only 100MHz. You need some LeCroy or Tektronix with minimum 500MHz bandwidth and factory calibrated attenuators 40, 60, 80 dB designed specialy for high voltages.

Silver rose transistor is special military grade KT926 transistor. He need big ammount of current injected in base to work properly.

Between nanopulse former IC 7400hc/hct and transistor put very high speed high peak current driver for example UCC37322 - 9A low side driver. Also driver can be inverted or non-inverted type because you can choose polarity of triggering with K1 selector switch. Russian ferrite marking 2000НМ is Manganese Zinc type with µi >= 2000. Also instead КТ926А could be used any high speed - high current mosfet or igbt transistor. Also UCC 37322 driver could be put in parallel (one over one's back) for higher output current ratings for high power transistors with bigger input capacitance.

Dally windings W1=6, W2 = 12.

Do not forget to decouple ICs Vdd-Vss (14,7) with 100nF ceramic caps. Also all inputs should have grounded guard rings. Best point for main ground is emitter of transistor.

scaling picture for details.

Hi Aloha - Thanks. Yes I did change the Core, I used a ferrite.This picture was an early version of my attempt to replicate the Nano Pulser.

I hope you don't mind, I fixed the picture. It wasn't loading.

This is an excellent diagram thank you!

I have spent a little time, trying to make my Nano Pulse much shorter in Duration.

Currently the best I can get is 10ns.

 

 

NOTE: R1 is not needed, if one wishes, a short can be placed in between pins 3 and 5 - I placed the resistor there for correctness.

Because my Scope is beyond the rated bandwidth (100MHz), 5ns is 200MHz, there are artefacts I have seen: 10x attenuation is not accurate, and I have shown 10x, 1x is more accurate and the output voltage is from 1.8 to 2.4 volts. This means a carefully selected Transistor will be needed.

Aloha is right, my equipment is not the best, not really fast enough, but we must learn to do the best with what we have. You can see, there is a pretty good pulse there, around 10 Nano Seconds, with a sharp Rise Time of about 6 Nano Seconds.

This should be enough to get a good response from a Mosfet, or a Transistor, if one is looking to replicate the works of the greats that require the Nano Pulser:

 Most Energy Devices require Nano Pulses of some sort. This is a very important field to know about!

Some may see that there is some correlation to my wave and the wave form Akula showed some time back.

   

We have a double Pulse after the initial pulse:

 

And compared to the Waveform from Akula: (Please remember this is at the Mosfet gate an d the Drain)

 

You can see there is two very short pulses after the initial Pulse, somewhat of a damped oscilation. It may just be coincidence, and this may not mean anything. But, something to watch for as you experiment! Turn on English Subtitles, Google does an absolute awefull job at Translation, but there is a lot of talk about Nano Second, Milli-Second and pulses of very short duration!

I have said this before, I believe this triggers Electron Spin Resonance!

Some have called this Ferro Resonance, Magnetic Resonance and so on. I would like to stay open minded at the moment about this.

Although Akula sold his soul, he has done a lot to help out the rest of humanity!

Sergei alias Edward Lee Dally home page

http://www.liveinternet.ru/users/edward_lee

CHRIS, now you may try replicate Dally. Examine and research windngs of his coil and you will find same partnered coils L7-L8 wounded in W.J.Hooper configuration and introduced sharp several kV nano pulse.

You can use old computer PSU for like inverter.

If you are interested i can give you further details about the coil ?

Best ever drawn pictures of Tesla 1.) and Hooper bifilar 2,)

Main Dally schematic. Keep in mind he made his BTG with very old 1MHz oscilloscope.

Now look carefully at markings 7 and 8. it represent main thing here. Connected to them is thin coaxial cable 50om RG50. More visual details at attached pictures.

Coils info - see attached pictures

1-фото - общий вид  - picture 1 main coil view
2-фото -48 витков - p2  minus 48 windings
3-фото -59 витков - p3 minus 59 w
4-фото -66 витков - p4 minus 66 w
5-фото -70 витков - p5 minus 70w

Итого: верхняя обмотка 83 витка. Upper winding 83 w

Under top winding coaxial 21 w marking RG50U - p7 and p8
Под ней: коаксиал - 21 виток RG50U.(фото 7, 8)

Под коаксиалом 159 витков провода 0,85 мм.(фото 9,10) Under coax 159 w, wire 0.85mm diameter - p9,p10

Далее 475 витков провода 0,33мм (фото 11,12,13,14)

Next under 475 w, wire 0.33mm - p11,p12,p13, p14

L10 is resonance coil 0.85mm conected only at several 1.5uF/400V capacitors in parallel tuned for resonance with main push-pull frequency.

L9 is output coil, 2.5 mm, top coil on pictures.

Tube is plastic with 46 mm diameter.

Need good grounding - copper pipe in background and thick cable to BTG. Could be welding cable.

Also worth try any Arduiono board with ATMega328 as push-pull generator instead TL494 with precise, duty cycle and pulse duration control.

Hi Aloha, I was hoping to make a team effort. It seems we have a lot that are here but not interested.

For a long time I have decided what to share publically. I have tried to be very careful to share what I am certain of, and try not to speculate too much, although I have from time to time.

I hope others here can see the point of my postings. Small pieces of Hard Data.

Yes please, I have a lot of the details, but yes, please lets share what we have saved from the history record!

 

I also have some images, looks like you have already posted.

Many Thanks

   Chris

You have big undershoot there. Almost bipolar pulse which is bad for Dally circuit. Try to correct it. Nano pulser need new smd pcb design and different manufecturers version of 7400 IC - HC, HCT, AC, ACT etc. But worth making universal nanopulser for free energy experiments.

Hi Aloha, thanks for posting the images!

Yes, there is. shouldn't be too hard to fix.
