I'm currently building a larger version with an ignitioncoil as stepup and a large 400VA transformer as stepdown.
I'm still using just 1,5 - 3v to drive the ignitioncoil so the output will be pulses with 2Kv.
And the output will be around 400watts.

Dare Diamond From Nigeria Says Hi
Originally posted by janost View PostIt is a stepup-stepdown converter.
The first transformer generates about 800volt pulses into an Avramenko plug. It charges the 630nF cap using a single wire.
When the gas discharge tube breakdown voltage, 200volt, is reached the cap discharges into stepdown transformer primary and transforms the voltage down and the current up on the secondary.
The GDT rate is about 20Hz.
The secondary is rectified and charges the 3,6v Li-Ion cell that feeds the supply voltage for the HV-blocking oscillator.
It works without a grounding-rod but the battery eventually runs out.
When it is grounded the glow from the GDT is stronger and the secondary of the stepdown generates a higher voltage with more current.
The second AV-plug with the 5,6uF cap is a way to tap the circuit and use a load without disturbing the selffeeding loop.
What I wanna do next now it to use AC and try to split the Positive on each leg with A.V.P and ground each extended A.V.P and thereafter see what will happen if I connect there outputs in Parallel or even series.
My taught is that DC have single Positive and Negative while AC have the Double for each and you know, A.V.P is no lenz Friend.
My problem now is the Spark Gap linked with capacitor capacitance and polarity that must be used each A.V.P.
Anyways, trial and error all the way....

F.Y.I
One example of using EDA (CAE/CAD) in collaboration with empirical
development/design to further understand, verify, optimize and develop an idea.
Wireless Power Transfer
http://edadocs.software.keysight.com...Power+Transfer
http://literature.cdn.keysight.com/l...990-6916EN.pdf
Original article that prompted the above EDA-CAE analysis:
Science 317, 83 (2007); Andr Kurs, et al.
Wireless Power Transfer via Strongly Coupled Magnetic Resonances
https://pdfs.semanticscholar.org/d17...32cf51fd6e.pdf
Note: the efficiencies (using an input sinewave); also, consider a narrow input pulse
train as an additional investigation step. N.B. It's a simple experimental setup as well
and Keysight [former HP] provides a generous "demo" package!
Test your idea(s) using conventional orthodox engineering practice; then add all your "WOW"
factors!!! if, in fact, it turns out they are even required??? [[and note the double integrals again]]
Keep in mind their goal is focused on power transfer over a large distance (1 to 2 meters).
No Standing-Travelling Waves or efficient "[HV pulse] sources are investigated in the above
(beyond the scope of the objective).
Another REMINDER: Check out Gorchilin's site for answers to many of the questions that have
recently been posed here. He provides some excellent "notes, animations, charts, and so forth."

Slicing up a dipole
(in best Julia Childs impression voice)
Today in the kitchen we will be... slicing and dicing up a dipole! First, go to your local electronics store and pick up a nice fresh dipole. Really any dipole will do, but for illustration let's take a DC dipole of 10 kilovolts. Put the dipole on your workbench and let's put on our high voltage safety measures and go to work!
Now let's prepare a nice resistive voltage divider with 10 steps to put across our dipole. If we make each resistor 10 megohms, then the voltage drop across each resistor will be 1000 volts, and the total power dissipation will be 1 watt, with 0.1 watt across each resistor. It should look something like this:
Now we have an electron current flowing from the "negative" end of the dipole to the "positive" end of the dipole. But because in nature every action has an equal and opposite reaction, the electrons at the "negative" end of the dipole will be phase-conjugate electricity! After all, if your dipole is a charged capacitor didn't you charge it by removing some electrons from one plate and forcing them to the other plate against their will? So, poor things, their natural reaction is flow back down the voltage gradient until they reach their original home again.
This is a good start, but for this recipe we need very, very pure cold electricity! So let's divide the divider again! Let's replace every 10M resistor in the chain with 10 1M resistors. Now we have 100 resistors, each with 100V voltage drop across them. And again! Now we have 1000 resistors, each with only 10V across them. The total current and power is the same, but now that first resistor, down at the bottom of the chain where the electrons first enter and begin to work their way back to the positive terminal, has very pure cold electricity in it. Still not pure enough, you say? Why then divide it again, until you have only 1V voltage drop. Or 0.1V. Or however close you need!
Voila! Pure cold electricity, suitable for use in all type of overunity recipes! Cover and refrigerate or freeze.

Incidentally, as the main criteria for Don's high power outputs is HF HV oscillations, then it should be possible to use one of John Bedini's 8filar windings coil, as an air core unit, and a few power and pulse input alterations, to get a very similar HF HV High wattage output. And, possible better control of the radiant capture. I also think that John's ten coiler was a "Tuned unit" which is why his worked so well and other replications do not.
Also, I wonder how good the grounding was at John's shop vs. that of most other replicators....

For capturing one-off and transient events where it's hard to get stable triggering, a digital storage style scope is indispensable. An analog scope is way better than nothing of course, but for any experimenters out there who have been waiting to get a digital scope because price tag is an obstacle, now is your chance. I use this scope for nearly everything and it has proven very robust even being next to high voltage circuits and spark gaps. Once or twice I've even had HV arc to the scope probe and it escaped without apparent damage. The ability to capture waveforms to a USB flash drive is also highly useful for posting on forums....
Thanks for the explanations on the NST. The unit I have is a CoolNeon 10Kv 30ma 30Khz. I shall look into getting another no fault ground unit.

Edit: silly me the 5202 is the 200Mhz unit!

I must say, I am not surprised that others' have had difficulties with the Tabletop device.
Also remember that putting the scope probe within a few inches of an HV oscillating circuit will pick up signal by capacitive coupling, but it's only measuring voltage. If your spark gap isn't firing then there's no current, and due to less load the voltage shown will INCREASE.

Simple is no exaggeration. However, one could not help being mistaken for thinking that he draws three coils: specifically in the first video.

Can you dig it? Here's the next phase of my project, improving the grounding. I scavenged a heat exchanger from a very large junked window unit air conditioner to use as a ground plate. Maybe it's not quite as big as a truck radiator, but it's not bad. Copper tubing, lots of surface area for ground contact. I wanted one with copper so I can solder a ground strap to it instead of having to settle for a mechanical connection. Low resistance (and low impedance) is the objective.
I have also called around for local septic companies that do backhoe work, so far it's been hard to find one that will tackle a small job like this. Hopefully I can get it done for $300 or so. I want to get the plate buried at least four feet down, preferably more. It's money I'd rather not spend, but I'm pretty much all-in on this project already so what's a little more?

Unscrambling the mud pie1
Many thanks for the detailed response to the Standing wave issue. Clearly, the Standing wave is able to maintain its integrity.
What is important is that YES, I have too been getting "Mixed" signals on my scope. Also, being old the sync is not the best, and so the Clutter that appears is difficult to isolate. At least I am now better informed as to what I am getting: a combination of standing wave pulses and pulse from the L/C component.
Incidentally I did start to read this thread from the beginning, time is my enemy, and gleaning through almost 11000 posts looking for something specific is quite a challenge. Its not laziness, relative priorities!
Once again many thanks. I can now concentrate on tuning and pulse procedure.

You could use higher frequency (mhz range) to get a practical wire length, then use the sub-harmonic (khz range) of your chosen frequency to resonate your tank circuit, you can get sub-harmonic by dividing your chosen freq. by 2 continously.
an example.
24.7 mhz is my chosen freq. that would make 1/4 wire length to 9.95 ft.
one sub-harmonic of 24.7 mhz is 24121 hz or 24 khz close.
you can chose a standard capacitor
example. my chosen capacitor is 4.7uf at 24 khz I will need 9.26 uH coil,
you can then design the L2 again based on 24 khz.
it would resonate just not sure about the standing wave.
but I got a very good Energy Transfer on a very loose coupling at 12v-36v input at resonance I had then around 2 amp input, at non-resonance 4 amps plus(depends on input voltage and primary coil).
might be even better at higher voltage.
those were the numbers I remember. hope this helps.Last edited by ricards; 10-18-2017, 04:58 AM.
