This thread is the continuation of flashligh2.


Here is the original Akula's circuit on we gonna work:

I modified the basic circuit of Akula so that it works like a high gain oscillator. It consumes almost nothing, 2 ma,.
 It has the effect of a hammer (the Circuit) on a bell (the Coils) by easily adjusting the natural resonance frequency of the coils which has already been vitrified in advance with a F.G. and a 28.2 Khz oscilloscope,


I used a 2 K multi-turn potentiometer for accuracy as a voltage divider and a small 1.55 volt battery as the main power supply for the circuit.


Here the modified circuit used i used in the test.

The test :


You will notice that at the natural (linear) resonance frequency of 28.22 Khz and an input voltage of 1.08 volts appearing on channel 2 and a current draw at the input of 2 ma, we still obtain a fairly good voltage approximately 33.6 volts peak to peak at the output.


 


When I exceed a certain voltage of 1.45 volts ( near the max of the battery) another effect occurs quite abruptly the frequency drops to 26.77 Khz and this is what I will call nonlinear resonance.
Quite surprising this effect is the voltage X8 and so is the current.

 

 

The reactive power developed by this circuit, is around 130 volts at the maximum of the battery, if we consider that the entire circuit is supplied with a single 1.5 Volt battery and there is no d external oscillator it seem good performance.

This small circuit has 2 BJT transistors 1 x NPN and 1 X PNP is the basic idea of ​​the Akula circuit. Thereafter I will modify the same circuit in order to be able to charge C1 and thus have this famous flashlight without battery.

Akula's basic circuit cannot be copied as it is built, having followed hundreds of tests of its circuit, I have not yet seen anyone succeed, but their way of thinking is very good, it you have to rebuild it while keeping the basic idea.
I believe I am on the right track.


A more explicit video will follow soon, I have a little problem with my camera.

I am currently working with a 1.2 volt rechargeable battery instead of the C1 and with recharging in non-linear mode

it has been going on since yesterday with only one milliamp of total consumption and 6 LEDs on.

It’s good.

p.s. I mean linear in continuous mode so very low power and non-linear in charge mode.

Question: Is your schematic correct in that your L2 only connected at one end?

Jagau posted this 18 December 2019

Hi Zanzal

the modify schema was to demonstrate non-linear resonance only so L2 was not plugged into one side alone.
I am trying a second schematic and it is not yet ready and that is what it gave me that the tension does not drop until very soon after 2 days.

I'm going to put it online soon and you're going to be able to try it,
Just for curiosity did you manage to achieve the nonlinear resonance effect as explained?

Jagau

Zanzal posted this 18 December 2019

Thanks Jagau. Looking forward to seeing your next schematic.

No replications for me for a few months still (at least). All my stuff is in boxes, it is hard to get access to anything and I have no space away from my little one who would take an obsessive interest in anything sitting on my desk. I've only been able to do a few very simple experiments in the last few months.

I do want to attempt a replication of what you've posted though. I think your observations and intuition are very good here and I like the path you are pursuing and intend to follow a similar one.

Jagau posted this 19 December 2019

@ Zanzal


Ok I understand your situation better now, maybe this little circuit will help you have a better time. You can also replace the 1 k resistor with a potentiometer and observe the interesting effects that will be produced.


@Atti


thank you Atti your circuit is interesting the POC produce very interesting effect, I will study your circuit,

thank you for sharing.

I reread Edwin Gray's invention and it gave me a fantastic idea that I had been looking for for some time. It was a genius this guy,

SPLITTING THE POSITIVE


Besides, when we look at Akula's setup it works the same way.
Finally I found a set up which seems to work well.


I'll keep you posted.


The best way is still to experiment.

Hey Jagau. Will love to see your experiment!

Jagau posted this 16 February 2020

hi Chris

Yes it is a very interesting thread that I had already read during my research when I joined this forum, I also proposed it to those who want a conclusive experience and with results. It helps a little to understand what Edwin Gray meant.


Yes, I rediscovered this very interesting concept, but as part of the Akula LEDS lamp.


There is no battery switch between the input and the output and the batteries must always remain fully charged, that is to say in the cricuit that I am currently experiencing.


For the moment I am experimenting this kind of circuit but with only 3 small rechargeable batteries at the input and  none at the exit.
The system has been operating for more than 2 days with 6 LEDs plus the operating circuit and the batteries continue to charge. I add other LEDs to stabilize the system.

I rediscovered this concept by re-reading the invention of Edwin Gray and by re-reading the book by Peter Lindeman on how to divide the positive. Do not forget that sharing the positive also applies to capacitors as in the case of Gray

I'm going back to my laboratory.
The best way is to experiment.

Jagau posted this 17 February 2020

Good morning all
After 3 days, without interruption the small circuit does not want to fall.
I added 3 other LEDs for a total of 9 LEDs.
The 3 small AAA rechargeable batteries did not decrease by 1 millivolt in 3 days, on the contrary, they remained stable.

A first observation; taken with the oscilloscope shows that the recharging of the setup is exactly 1/4 of the resonance frequency of the main coil which is at 28khz.

Here is scope shot:

You can notice the sinus shape in the center.

A view of complete set up, circuit, potcore, led and batteries:

Did anyone try my first circuit at the start of the thread?

Other observations, photos and a circuit will follow.

P.S. John Bedini wrote on his web page: ''This has been on my pages forever, but nobody understood it.''

I wonder what he meant by that

Jagau posted this 18 February 2020

Hi all

I would like to present you a very simple circuit to make but how useful.

It's the same one I use for what's going on in the project above.
You can use the 2 inductors of your choice as long as they are on the same core, for mine I use a potcore.


As soon as they are connected by 3vdc it starts to oscillate on its own and in addition if you look on your oscilloscope at point A and B it adjusts by itself to the resonance frequency. Very nice little circuit simple and easy to do. 

Thereafter I will be able to explain to you how I achieve what I did.

I think it was one of Akula's favorite circuits but modify by me as you can see at the beginning of this thread.

P, S, The variable resistor 1K does not change the frequency, it is there to adjust the gain of the circuit only.

Wistiti posted this 18 February 2020

Hi Jagau. Does one of your l2 leg are not connected to anything like in your schematics on the top of this tread?

It will be nice to know a bit more on your experiment.

Thank you!

Jagau posted this 18 February 2020

Hi wistiti


Yes these are the first modifications at the beginning which had been made in the system has had an evolution. It is for this reason that I redid the basic circuit as simple as possible above, it is the same as on the little brown board on the photo above. The goal is to progress slowly but surely in the explanation of the circuit if you build the last little circuit very simple above, I could guide by the following it will be less complicated like that, I think.

@ CD 

I understand you very well CD, there are so many interesting things to do in this forum that we do not want to disturb others in our own experience, but it is part of the game. Don't worry CD, I'm also following your experiences with a lot of interest.

Other questions?

Some news:


At the fourth day the system still works as well the voltages of the 3 batteries are always higher than the nominal voltage of each which is 1.25 volts, they stand between 1.3 and 1.4 is great.


Another observation, the mornings of strong sun the ions increases a little and the evening decreases a little but never below 1.3 each.

 

Jagau

Jagau posted this 19 February 2020

Hi all

Now we will add 3 LEDs in parallel and 2 others battery in the circuit.
Place an ammeter at point C and adjust the 1K pot to get 3 milliamps.
I hope you have successfully completed this part because the next one is the most important.

News
Since last saturday, February 15, the system is still working well. The LEDs are on and the voltage barely fluctuates.
Jagau

 

Wistiti posted this 20 February 2020

Thanks Jagau for sharing! I will try to replicate when the time permits. Maybe the next weekend.

Jagau posted this 20 February 2020

Hi Wistiti, You are welcome with any questions.

Okay
I know that rechargeable nick-cad batteries have a capacity each and a nominal voltage. So it is easy to calculate the time the circuit would operate under a certain load and the voltage would drop linearly every 24 hours.

This is not what happens, the voltage varies in + or - no more than 0.001 volts and it remains stable at above the normal nominal voltage for this type of battery which is 1.2 volts, they are all the 3 at the over of this nominal voltage and sometimes reach 1.4 depending on the hours of the day.


Another beautiful puzzle to elucidate?

Jagau

Jagau posted this 20 February 2020

And now the first version of the complete circuit.

 

I am going there gradually so that you can understand how it works

Jagau

 

Jagau posted this 21 February 2020

Good morning all:


In this sixth day of experimentation I have built since yesterday a second circuit which works just as well as the first so we can replicate it.


I build this test circuit with larger batteries and the power is evident on the LEDs. The goal is to slowly increase the power to make it shine with an incandescent lamp.

Jagau

Wistiti posted this 21 February 2020

Hi Jagau. Does your replication use again a pot core? Have you try with another type of core? Ring, rod, metglass, ...

Thank you!

Jagau posted this 21 February 2020

Hi wistiti 

You understand that I would like to improve this circuit which works in very low power with a larger one, so as not to change a winning combination I have to replicate exactly the same with a potcore.
However I would like to know if another has succeeded with a different core.


Jagau

Jagau posted this 21 February 2020

Hi all

One of the advantages with this kind of auto oscillator is that it does not waste energy in order to produce a pulse.
The frequency is determined by the RC network which produces a constant time with the 200Pf capacitor and the input impedance Z of the coils to pulse.

With this capacitor we can oscillate between 20khz and 130khz, so resonant frequency is egal to  1 divide by ZC 

in other words it adjusts itself

Jagau

Jagau posted this 21 February 2020

In this project we have to consider 3 key elements.

The first is the nonlinear resonance, as demonstrated by the thread

The second is the theory of "YoElMiCrO", which speaks of the negative slope in ferro-resonance

Yo quote:
Voltage increase is related to the negative slope that has the magnetic permeability of the core

the third and very interesting one is by Edwin Gray on electrostatic transfer while sharing the positives.

This is a lot to check but should be checked, 

Jagau

YoElMiCrO posted this 25 February 2020

Hi everyone.

I could not be active in the forum due to work problems.
But whenever I can go to review all the findings they find.
This is a community like no other on the net.
I think I can continue with the experiments I left a while ago.

@Jagau.
If you don't mind, I pass a circuit with which you can see
the behavior of the back emf when it returns from the negative slope in this treat.
As Vidura says, in conventional designs it is forbidden to saturate
any ferro-magnetic core.
Now...
If we start thinking ...
It turns out that in the linear region of the hysteresis curve, during the ton cycle
B grows and permeability grows too.
but when we turn off the sw the current drops (-di / dt) but the permeability too.
However, if we make permeability pass through its negative region during
Ton cycle, when Toff touches the current will fall as before, only the permeability
It will increase now.
If the inductance grows during Toff and the current remains relatively constant, we can
Have an energy gain.

Thank you all in advance.

YoElMiCrO.

Jagau posted this 25 February 2020

Hi Yo

You are always welcome for your comments Yo.
As you can see in my first experience at the start of the thread, I noticed this effect you are talking about,

when the inductance grows the frequency decreases, is that what you mean?

Jagau

YoElMiCrO posted this 25 February 2020

Hi everyone.

@Jagau.


Yes, that's what happens.
It turns out that Ton's time is compressed, because the current that is
reflect of the load is the component that defines the static path in the circuit.
For stable operation, this current must remain constant throughout
at this time, it should be noted that the turn ratio should be calculated using
Biot-Sabart's law and not Faraday's.
On the other hand, during the Toff cycle said primary peak current should
fall to 0, in turn the magnetic permeability of said core (ur) when returning from the
negative slope until the value you have for Br will increase the primary inductance.
In this way the time of Toff expands, being a non-linear process and not fulfilled
volt-second equations (VpTon) = (VfbToff).

In the shortest possible time I climb the circuit, thank you.

YoElMiCrO.

Jagau posted this 25 February 2020

Hi Yo

Completely agree with you the law of BIO-Savart is that which we must use in the cases of non linearity and in time variation, the law of faradays is for the very linear systems in closed loop.

Your future circuit to come look very interesting.
Thank you for your comments.
Jagau

YoElMiCrO posted this 27 February 2020

Hi everyone.

Yes, we all know that the rise / fall time is controlled by the current
of the gate, forget about the 500 Ohm resistor, just to adjust that time.
You adjust it after having Ton and frequency, looking for the least noise in the way
of drain wave.
It occurs to me that we can use the miller capacity of the mosfet, I'll try!

Thanks in advance.
YoElMiCrO.

About the leds project.

After almost 2 weeks, the batteries in series have started to drop slowly except that in reverse which is still held at 1.4 v

Small update


On the circuit that I sent you,

the more I increase the load at the output by increasing as an example the capacity of capacitor

the more consumption at the input decreases and the output voltage increases with no change in frequency,

very interesting observation, under study

Hi all

As you can imagine, it is not only us who seek to understand the mystery of the small lamp of Akula.
I recently found a very interesting article from an Indian engineering college which offers a topoly buck boost converter as Yo's proposal. They title their articles:

 

Self Powered Buck-Boost Converter for Low-Voltage Energy Applications.

Hi my friends

I am preparing an update for my trhread
I haven't forgotten you, see you soon
Jagau

update


Hy my friends


By carefully studying the very well-known schematic of A. Melnichenko;

 

We can easily see what Chris has shown us lately. In a complete cycle we can divide it into 4 equal parts of 90 degrees.


I redid this schematic so that it works in the project of the small led lamp, because this small lamp uses the basic principle of the operation of this schematic.


We must have 3 coils, a diode and a capacitor, I will show you in a short video all the power to develop by this arrangement of 3 coils of which 2 transmit the starting impulse and I cancel the one of the middle by disconnecting it in a natural way and by reconnecting it in series and only by capturing the way in which the coils interact with each other, as Akula said, you must capture the functioning of your coils first.


No need for a complicated switch, just think about it. When I transmit the pulse (phase 1 and 3) I am in very low inductance about 45 microhenries, therefore in energy saving, when I receive at the output the inductance goes from 45 microhenries to 350 millihenries, which gives me a great increase in power.


The schematic is the basic idea of ​​the operating principle but if you plug it in as it is present, it does not work as I had already demonstrated in another post by shorting a single inductance we can not have an inductance increase in that this during the relaxation (disconnection) of the circuit in phase 2 and phase 4 of a cycle as demonstrated by Chris and CD in another post.


I am preparing this short video to show you my latest advancements in this project.


Jagau

Jagau posted this 19 May 2020

So this simple confuguration gives me at the input inductance is 58.85 uh

and at the output inductance is 348.4mh

The setup

 

It is ja way in which I connect the 3 coils which give me this advantage. As the inductance increases considerably you can see in the video the effect produced.
As you will notice in the setup, it is imperative to have a square wave AC, ie it goes through zero and increases in negative with the same amplitude as in positive.

Function generator who act like S1 in melnichenko schematic and no need of S2 switch,

And more at 21 Khz a functiongenerator have an outputt power contrill by the amplitude of about 45 milli watt and it is normal. I apply this 45 mw to this set up


Here the difference between a square wave AC and DC.

The effect is completely different when I use AC,

so AC square wave is better.

The video is almost finished, I'll get back to you with that

Hi my friends

Here is the video:

 

Scope show across  0.1 ohm board current of 19 ma and voltage 5 volts, 95 mill watts or 0.095 watt at 19 khz AC square wave at resonant frequency and we get 550 volts RMS in 2-3 sec.

 At output i discharge an incandescent lamp of 10 watts 120 volts in, note the very fast increase in voltage with so low input power. I will surely lit some leds in my project of lamp with this coils configuration.

I would never have thought of one day lighting an incandescent lamp with the very low power of a function generator.

Asymetric transformer plus resonance is the perfect combination to get above unity.

Next goal, would like this leds lamp a  project succeeds.

Chris posted this 21 May 2020

Hey Jagau,

Very nice! Thanks for sharing!

We know, Charge: Q = C ⋅ V and we can calculate the work: W = 1/2 C ⋅ V2 so a quick calculation shows you have: 0.875000 Joules across the cap when its at 500V. This is all for 0.095 Watt Seconds, or Joules.

Best wishes, stay safe and well,

Jagau posted this 21 May 2020

hi Chris
  The system has a recharge time of 2 to 3 to make an average with 2.5 we have e = (cv square / 2) = 1.059 watt /2.5 second=   0.4235 watt second  and and with the amplitude of the F.G. completely closed, I still have 47 volts RMS, 

The 10 watt 120 volt lamp is only to demonstrate the rapid increase in charge mode.
The LEDs take almost nothing. I will demonstrate later.

Hi chris


At the input I only consume P=E I  5v x 19 ma = 0.095 watt
and at the output I have 7Uf x 550v squared /2 and divide by 2.5 sec average = 0.4235 watt per second

do we arrive at the same result,  don't worry i can be wrong, tell me what you think your idea is important to me?

Hey Jagau,

 

double Uf = 7.0;
double F = Math.Pow(10, -6) * Uf;
double Q = F * 550;
double W = 0.5 * F * Math.Pow(550, 2);

Q = 0.00385
W = 1.05875

 

A quick method:

  • ‭0.095 x 2.5 = 0.2375‬ Watts over 2.5 seconds or 0.2375 Joules Total Input.
  • 1.05875 Joules = 2.5 seconds, to get 550V in a 7Uf Cap = 1.05875 Joules Output.

 

COP = 1.05875 / ‭0.2375‬ = ‭4.4579. If someone wants to correct me, please, I would be grateful to point out any mistake.

Best wishes, stay safe and well,

YoElMiCrO posted this 21 May 2020

Hello everyone.

@Chris.

You're right, power is energy per frequency (Ef) or energy between time (E / t)
as well as voltage per DC current.
So the energy expended to produce 550V in a 7uF capacitor is ...
EIt = 5 * 0.019 * 2.5 = 0.2375 joules.
Let's calculate the energy stored in the capacitor ...
E = Vc ^ 2C / 2 = (550 ^ 2 * 7 * 10 ^ -6) / 2 = 1.05875 joules.
The energy efficiency is Eout / Ein = 1.05875 / 0.2375 = 4.4579.
Corroborating your calculations.

@Jagau.

Yes, it definitely shows AU.
In all the experiments I have done I always had the same
problem, only E appeared but nothing of I.
The only solution I found was through capacitors, these
they store charge E and have the property to use time to
produce I, since charge equals current times (Q = it).
It was for this reason that I dedicated myself to finding another way.
Bravo, good demonstration, we must analyze how it can be done
so that it is 100% functional in closed loop.

Note:
If you look closely at the input waveform, you will see that your system
it is ferro-resonant, it is necessary to obtain loads and it is
with what Nikola Tesla discovered in his time in another way.

YoElMiCrO.

Jagau posted this 21 May 2020

I had a lot of trouble sleeping last night.

Hi all

For those who would be interested in building, something you should know when making your 3 coils, they must be wrapped one on top of the other with a gap made of electrical tape (air space) between each coil

. In fact it is as described in the patent of Andrey Melnichenko:


  This is obtained by the presence of a weakly magnetic air or space, resulting in a magnetic field energy greater than the work of the current source to be magnetized and which can be converted into electricity during demagnetization.


In addition, the 3 coils must have the same number of turns which ensures the same inductance. By doing this the second and third coils will be a few turns longer, as Don Smith mentioned, a few turns longer on a two-sided side compare to first one.

Hi Jagau.

I'll try as soon as I have the shortest time.
Thanks for sharing the data.
I have a question, what are the characteristics of the capacitor
that you have connected, it looks like oil.

Thank you in advance.

YoElMiCrO.

Jagau posted this 22 May 2020

Hello yo
For the condenser not sure if it is with oil it is what General Electric used in the power supply of high power. It is a Delektrol number 19A13457P2
I believe that the specs can be found on the internet.
For spec: 7 Uf-660vac GE trade mark.
I have 2 of these capacitor, it was used in power supply CVT in conjunction with a special Xfo built in the 1960s, maybe the floyd sweet team worked on this plan, being himself an ex employee of GE in usa. 

I send you a schematic, they even used ferromagnetic transformer technology at that time.

I joint you a description form the book of this P.S.

P.S. I will redraw my schematic, he is difficult to follow,I will do it again for a better understanding

Have a nice day

What is a Scalar:

In physics, scalars are physical quantities that are unaffected by changes to a vector space basis. Scalars are often accompanied by units of measurement, as in "10 cm". Examples of scalar quantities are mass, distance, charge, volume, time, speed, and the magnitude of physical vectors in general.

You need to forget the Non-Sense that some spout with out knowing the actual Definition of the word Scalar! Some people talk absolute Bull Sh*t!

The pressure P in the formula P = pgh, pgh is a scalar that tells you the amount of this squashing force per unit area in a fluid.

A Scalar, having both direction and magnitude, can be anything! The Magnetic Field, a Charge moving, yet some Numb Nuts think it means Magic Science!
