Hey, guys

As there are multiple paths opening from this experiment replication, this thread will hold all the data related to the center-tap version.

Here is something following Don Smith's suitcase device:

It's much easier to achieve full-cycle magnetic resonance if L1 is wound over both POCs.

My Friiends,

@CD, Only when you have time my Friend!

CD is correct! Wistiti has been showing that Circuit for a long time now! Also, yes, the Gapping of the Core, can sometimes, make all the difference, but not always:

A small Gap between the Cored Partnered Output Coils to delay the Magnetic Field Mutual Coupling between the Coils. Circuitry can also be employed to delay Conduction on the second Partnered Output Coil.

Ref: How to build your own Above Unity Machine


In this post, we covered the Core Movements and the action of Residual Magnetism. The Videos of Raselli1 are shown here again:


You should be very proud! You show a Decrease in Input Current when the Machine is configured correctly, from 32 ma to 30 ma, which is a great start considering this is only the start!

This all depends on Magnetic Fields and the Movement of them, a pressure if you like. Slowly increasing the load should show the Input Current become less!

I hope this helps some!

Best wishes,

Hey, guys,

A little something from what I'm experimenting these days:

Hey CD,

Ah yes I think I see it now. My bad.


We have covered the Circuit before: Here. Please correct me if I have it wrong!

Best wishes,

Excellent demonstration. Well done
If I can allow myself a question, if instead of the lamp you put a variable load to what intensity you can increase it without the consumption of P.S. increases?

Hey guys,

In the above schema, I was wondering what happens if I make L1 partially non-inductive. The result:

Notice the amps going down under load. Thanks for watching!

cd_sharp posted this 20 December 2019

Hey, guys,

A little experiment I had on my phone. It's showing that we can make L1 over both POCs and still get sufficient voltage.

Chris posted this 03 April 2020

Hey CD,

Awesome work my friend!

I bet your'e happy with this result! I wonder, when you get time, can you please post a circuit? I wonder as to the Centre tp, its hard to id in the video.

Best wishes,

Is there a difference with open core vs close?

cd_sharp posted this 04 April 2020

Hey, my friends

Sorry for the delay. Chris, you're correct, that's the exact circuit. I think Wistiti has been showing similar circuits for quite some time, based on Don Smith's devices.

Wistiti, my friend

Is there a difference with open core vs close?

Yes, it makes all the difference. Adding the other core half makes the effect go, meaning the load-POC2 pair do not input energy, but adds to the "consumed" power.

Also, if I take out the capacitor, the effect disappears.

Thank you, guys!

Wistiti posted this 05 April 2020

Hi Chris. Is it me or the cap are in the wrong polarity in your schematics?

Wistiti posted this 05 April 2020

Hi CD. Just for curiosity, have you try to short your output? I think it will not draw more on your input...

Chris posted this 17 April 2020

Hey CD,

As always my Friend, Excellent work, Thank You for Sharing!

Don't forget Delayed Conduction, this can help get the Voltage up. Listen to what the MEG Team said:


A Transorber is the same as a TVS or a Transient Voltage Suppressor.

The Voltage, if sudden Conduction is at 1 Volt compared to sudden Conduction at 15 Volts, think how much more there would be.

Remember: I = V / R, Ohms Law, so getting your Output Voltage up is important.

Be careful though my friend!

Best wishes,

Hey, Chris

I took your advice and check what delay conduction can do. Here it is:

Thank you, guys!

cd_sharp posted this 11 May 2020

Hey, guys

One more little step:

Notice the input going down even more under load.

Hey Guys,

The SR193 info is good! A good example! I have a ton of Data on this, and guess what:


358 MB of Data can be downloaded: Here in Zip format, I use 7Zip for compression, no password.

cd_sharp posted this 08 December 2019

Remember, in here we've seen that the center-tap circuit does not achieve full-cycle magnetic resonance. I needed to add a small capacitor between the two POCs to achieve that.

But in the above setup the cap is not needed.

Hey CD,

Yes a Center Tap, I have been familiar for some time:


Naturally Existing Ferromagnetic Resonance.
Date: Mon, 12 Apr 2004 12:16:01 -0500


You have me at a disadvantage! My present physical condition and that of my beloved wife severely constrain my time. My first job is taking care of her, 24/7. I do a little work in snatches and grabs, as I can, and that’s it. I’ve been steadily shucking tasks, and still have more than I can do in the time I have.

Everything I know about the VTA was released. I never knew the full conditioning program; only about 80 to 90% of it. I do know that the coils he used had a secret center tap, but am unaware of just what he did with that centertap. The actual discharge control circuit was built for him by Walter Rosenthal. Walt also saw the closed loop self-powering system, which I did not see. Basically I just stay away from the VTA insofar as possible. It was a wonderful invention, and it could also produce antigravity. But after a sniper with silenced rifle took a shot at Sweet, just missing him as he stumbled and fell, Sweet would never again discuss or do anything with the antigravity experiment. He felt he would be immediately killed if he tried to do anything with it.

And yes, I did give him the standard nonlinear optics equations, since such were involved in the conditioning process apparently, and since Sweet’s MS EE in the 40s or so was before the advent of nonlinear optics in 1972 when the Russians briefed our guys on it. Sweet had excellent math capability, however, and very rapidly absorbed the gist of NLO. Whatever was puzzling him in his activation procedure (at first he banged and banged away, finally getting a good activation), he immediately resolved it, apparently with the use of NLO equations. The next unit he built produced 500 watts output. It also produced mostly negative energy, which is a quite different bear from positive energy! It was its production of negative energy that so intrigued me, because since positive energy density makes gravity, then negative energy density makes antigravity. And so it proved to be.

On the other things, after the heart attack in 2001 and continuing hypoxia, many of my “files” are no long there or no longer accessible. That and the years intervening mean that I lost some of the details. Also, remember I was never a bench person, but always worked with those who were. My job was to examine some kind of strange behavior or anomaly, and then try to figure out what the devil that was or could be, in terms of physics.

So I hope this gives you some perspective, but I’m unable to provide actual construction details. Probably Walt Rosenthal can do that closer than anyone else, although Sweet’s method of “hiding” it was to tell each person a different story. That way, they could never get it sorted out completely.

Several other researchers have indeed activated magnets, but only for times up to about 5 weeks as the activation slowly decays. Sweet, however, had apparently discovered how to do it in a permanent fashion, so that only a severe perturbation (such as striking the magnet with a hammer) would cause loss of activation.

If you just want to build a working COP>1.0 motor without too awfully great a problem, then use the Takahashi approach. Wrap a linear permanent magnet motor around in a nearly complete circle, so that the back mmf is confined to a very short region. That motor will self-drive all the way around to the back mmf section, and there’s where the “payback” is if the symmetrical regauging of the circuit is allowed to be maintained. Instead, place a pole-piece over that back mmf section, with a coil on it, and with a tiny trickle current in it. Then as the rotor magnet reaches the back mmf section, abruptly (as with a magneto-like action) break the current in that polepiece coil, to evoke Lenz’s law very strongly. That gives you suddenly a cancellation of the back mmf, by it being momentarily overridden by the abrupt field from the polepiece. This can be sufficient for the back mmf to be eliminated during the time the rotor magnet actually passes through. So the net effect is that you eliminate the back mmf or most of it, for only a small cost to you. That gives you ASYMMETRICAL regauging and a momentary breakup of the closed current loop circuit, and momentary injection of excess energy (in a critical manner) from the external environment. All that is necessary in order to get a COP>1.0 engine.

Another engine that works as advertised is the Kawai engine. Effectively, by adroit and very efficient (photo-coupled) switching of the flux path itself, it also eliminates the back mmf of a magnetic motor. That essentially makes the COP of the Kawai motor system double the innate efficiency of the engine, since half the energy in a normal engine is used only to destroy the dipolarity by fighting the back mmf.

If you start with a high efficiency motor (say, a 70% or 80% Hitachi magnetic motor, which are available commercially), and you get a good and efficient application of the Kawai process arrangement, your modified motor should give COP = 1.4 or 1.6 or so, respectively.

Note that conservation of energy is rigorously upheld in those engines, and the OVERALL efficiency of the system is still less than 100 %.

And there is one of the rubs; most in the overunity field do not seem to know the difference between efficiency of a system and COP of that system. The efficiency is defined as the useful output divided by the total energy input from all sources (environment and operator). Or use power output for total power input, if in a steady state condition. The COP, however, is defined as the useful output divided by the energy input by only the operator. If the external environment inputs some extra energy, that is not counted in COP, but is counted in the efficiency. No engine will have efficiency greater than 100%, but with an extra environmental injection of energy, it can jolly well have COP>1.0. E.g., consider a solar cell array powering a system. The solar cell array’s efficiency may be only 20%, so that it wastes 80% of all the solar energy it receives as input. Yet it has a useful output of that 20%, while the operator himself inputs no energy at all. So its COP = infinity! So is the COP of a windmill-powered system, and a hydroelectric powered power grid and all its loads.

Hope that helps.

Best wishes,

Tom Bearden

Ref: - Naturally Existing Ferromagnetic Resonance


You, my friend, will see some familiarity's in there.


Also, ask the question, Tom's story, about the Back EMF Motor, all they are is just coils, why would he go to such length to tell me about that?


Magnet Conditioning is complete BS, and it makes me rather angry to read about even now, its such a HUGE LIE, but I suspect Tom Bearden was FORCED to tell this lie! By his Handler and the CIA. Reading between the lines, it is evident that Tom Bearden did doubt the Condition Lie!

We must learn from our past mistakes, and mistakes those before us have made, learn to be Better, be Stronger, be Self-Less, and only then we can evolve! We do not need Rule or Govern, not in the way we currently understand it! We need Leadership, and Wisdom, quality's most all of our current Govern does not have!

I hope this post gives you some insight!

Hey, man I think he did what he was ordered to, but he also planted the good seeds. You, my friend, have a sharp mind. You can easily distinguish between the good and poisoned seeds.

Hey Wistiti,

My Friend, Thank You! Fixed now! CD, perhaps you may want to verify, make sure I have it right also?

Best wishes,


Chris posted this 08 April 2020

My Friends,

CD has shown how Important this work is! I ask all Members, All Readers, Please learn and replicate this work. 

This is so important. Please replicate, learn how this all works.

Best wishes,


Chris posted this 13 April 2020

Hi Dale,

I would like to suggest you do the experiments. Much of your questions will be answered in the experimental results.

In these experiments, the Coils each have their own polarity! A very Specific and Important Polarity. This is achieved by the Diodes.

In CD's Circuit:


You will note, each Coil has a polarity Dot, Primary to Secondary is conventional. Tertiary is not Conventional! Assisting the Primary! Opposing the Secondary. So again, there is a very Specific and Important Polarity!

When you have your gear unpacked, do these experiments and you will see the very important meaning!

Best wishes,

Hey, guys

My latest progress:


Himaliayan Phonix posted this 11 May 2020

nice vedio shared  cd ,,,,,,,,, if i got it right you firstly are using only one coil and the bulb has less shine , then after connecting the second POC the bulb is brighter and consumption is going down ?


what if i don't have a scope , how to find this effect ?

what is is more critical frequency or dutycycle here at this point ?

cd_sharp posted this 11 May 2020

Hey, Phonix

You're right.

what if i don't have a scope , how to find this effect ?

My best advice is to follow Wistiti . He does not use an oscilloscope either, but is doing a great job.

what is is more critical frequency or dutycycle here at this point ?

Both are important.

will it work in certer tap non-inductive way ?

I checked out your setup and it looks like it has too much inductance. I also suggest you split the POCs, make a clear separation as to delay their EM interaction, as Chris likes to say "give them space to breathe".

I hope this helps.

Bonjour cd, and all,
Il y a quelques années, j'ai remarqué cette vidéo.
Ce n'est pas mon travail, mais je pense que je vois une analogie avec le vôtre.

En espérant que cela aide

Hey, guys

My apologies for the delay.

if instead of the lamp you put a variable load to what intensity you can increase it without the consumption of P.S. increases?

I don't have such a load. Jagau, are you thinking about anything specific?

perhaps you may want to verify, make sure I have it right also?

Yes, it's correct.

Just for curiosity, have you try to short your output?

Not yet, I'll try it.

cd_sharp posted this 11 April 2020

Hey, guys, I'm very busy, but I promise I'll be back soon.

Chris posted this 11 April 2020

I'm wondering about shorting the output coil.


Hey Dale,

A Shorted Coil represents the Maximum Load, bringing the Impedance down to absolute minimum. This means maximum Current will flow in the Coils. Maximum Magnetic Field will be a Result.

These machines work on the Interactions of Magnetic Fields, so the higher the Magnetic Fields, the better these machines work.

Load is important, when starting off, one has to choose the load wisely. Magnetic Field Interactions are hard to get right, but once one has learnt these interactions, then it becomes much easier.

@CD - My friend, when your'e ready my friend! Stay sate and well, Everyone stay safe and well!

Best wishes,

i have made a diy transformer using a TV yoke ferrite core. thick yellow wire is primary and for secondaries i have wound many wires for connecting them in different configurations, ( multiple POCs)  what is are your thoughts on my transformer? will it work in certer tap non-inductive way ?

normally when i drive this transformer with 12 volts , it outputs 220volts  ( up to 300watts it gives when used as inverter transformer,, when drived more then 300 watts it saturates the core)

kindly suggest me with your thoughts ......... picture attached

Hi, I attached my new wounded coil , it's just like Don smit's style and each poc contains 100 turns on PVC pipe , I tried it air core but didn't got good results , I am planning to fill the PVC pipe with crushed ferrite or magnetic materials. Kindly suggest me with your thoughts on this setup , I am thinking to sparking some high voltage , is there any possibility ? Primary coil should must be quarter of one poc ? My secondry coils are 100+100 , so my primary should be 25 yes ?

Hey, buddy

A great deal of data from SR193, a lot to dig into, especially his forum posts. Thanks for the archive!

Himaliayan Phonix posted this 4 weeks ago

HI Thanks for your great suggestions and thoughts, i am very glad that there are many to help me here when i need help understanding this technology.

i am a repair man of electronic devices and i think i have some knowledge of high voltages and safety measures so i will try to sparking not higher but around 2000volts, for this i have a ready made 12v to 2000v converter..(high frequency neon sign transformer ) . i red some info written and explained very perfectly by cris that  my primary coil should be less turns so i can achieve sharp pules easy way  ( fast rise and fast decay time of primary pulse)  

i don't have a scope and i will be trying like people doing in 1800s

i understood that my secondary should act like a dipole antenna and i need to find the point where the pulse in my dipole output should built and collapse at same moment , additionally i have an earth connection with thick wire directly gone to a diged and proper earthed point. i will be working under high voltages so i will keep my digital multi-meters far away and stick to analog meters



cris thanks for sharing the work  data of sr193........ i was thinking about sr193's setup when i was wounding my coil and then you shared what i needed ..... for me you are a light in the dark and i will follow you

your explanations are very helpful and valuable thanks for your efforts

Hello All,

I'm wondering about shorting the output coil. Is that to 'remove' it from the system? Or are you measuring the output from it while it's shorted? From coil to meter with meter to a separate ground.

One of my strange units gives a lot of output from a shorted coil. That was the death of the first meter.... The coil, in essence, becomes an antenna of sorts in that one. A very big surprise for me! It just seemed to be the thing to try and it worked.

Have a good day,


dale morgan posted this 13 April 2020

Hello All,

Sorry, I must be having a terminology problem. To me a shorted coil is this,

So in my mind then you're grounding a lead from the coil. my mental misunderstanding is solved. Thank you.

Have a smooth day,


dale morgan posted this 14 April 2020

Hello Chris,

Yes, I agree. Just can't get started with building again, yet. I very much want to!

cd_sharp posted this 4 weeks ago

Hey, Himaliayan Phonix,

Nice setup. I don't have much experience with air coils. I think Loz studied the air coils setup of Don Smith. You also might want to review this topic.

I am planning to fill the PVC pipe with crushed ferrite or magnetic materials.

Making a ferromagnetic core yourself from powder is possible, but it's not easy. I don't recommend it.

I am thinking to sparking some high voltage , is there any possibility ?

Yes, it is. I stay away from high voltage while researching. Of course, if you're skilled you can do it. The spark gap does not need to be high voltage. SR193 used a medium voltage:


I recommend caution. HV can kill you.

Primary coil should must be quarter of one poc ? My secondry coils are 100+100 , so my primary should be 25 yes ?

Yes, it's a good starting ratio, but you need to fiddle down, reducing 1 turn at a time and see what changes. Every device has its own preferences. Do you have access to an oscilloscope?

Best wishes
