This is the device shot taken from youtube. I noticed there are several versions of the schematic, slightly different that were posted on several forums. I took the screenshot from the video uploaded by Chris and I will consider this one as the basis for my replication:

I also created a Circuit Wizard file. It's a habit of mine to run a simulation before trying anything for real, just to make sure nothing blows up. It would be useful if we would be able to upload files also. I'd like to share the .cwz file with you.

This is a classic unit that I have watched with interest. So wished that they would allow some others to know how it really is made and works. The world seriously need this kind of tech now. Soon my friend, soon.

I have some trouble finding MBR3545 diodes, so I'm looking for another type of diodes. Here is datasheet:

http://www.mouser.com/ds/2/169/mbr3545_thru_mbr35100r-218591.pdf

It has a max current of 35A and forward voltage of 0.68V.

Considering this, do you think it would be a bad idea to use instead MBR1635?

http://www.mouser.com/ds/2/149/MBR1660-1011072.pdf

It supports a current of 16A (but that should not be a problem for max 30W power) and has a lower forward voltage, 0.63V. Do you think it's a good idea?

It's a work in progress. There is something else I don't know for sure, the inductance that I marked in red:

which is this one in the schematic:

I can see there are 7 or 8 turns. To anyone that replicated this, how many turns did you use for this coil?

I finished the circuit and I gave it a try. Only LED HL11 lights up for a second and then turns off. I probably made a mistake ( although I double checked everything before powering it). Any advice?

Hi Cd_Sharp - If I may recommend, perhaps smaller steps?

Do you have a function Generator? I would try to resonate the Coils and find where the resonant points are, look at Input and Output at these points.

The problem is all coils will have slight differences in Inductance and so on. 

Also, like the MrPreva Experiment, the Coils will have an optimum configuration, Akula also used a Function Generator to find the resonance point on his Coils also:

 

I hope this helps!

Hi, Chris!

Yes

I would try to resonate the Coils and find where the resonant points are, look at Input and Output at these points.

Do you mean I should put them in a Mr Preva experiment schematic and find the "magic" frequency? This depends on the value of the capacitor also, right?

Chris posted this 31 March 2017

Hi Cd_Sharp - That's just what I would do.

The Coils are where we need to concentrate, looking at the Current Directions at the same time. Ensuring we have met the requirements needed to "Generate" the excess Energy we are looking for.

It may be the Core may need to be changed? I have found some cores better than others? 

Just trying to help, hope you don't mind me pointing out these things.

I posted this to My Replication.

All the best

   Chris

 

Edit: Sorry, your question on the Capacitor, normally: f = 1 / 2 PI Sqt(L C)

But in this situation, you will find, this is not so important, the capacitor is just acting as a Reservoir and the Resistor's R1 & R3 is used to take the square edges off the DC Switching.

Hi Cd_Sharp - I should say, Load is important. This depends on the device as to what is meant by this. But basically, the Resistance of the Load along with the Resistance of the Coils (NOTE: Resistance of the Coils changes during Operation) determines the Current that flows in the Coils.

The Current that flows in the Coils IS the Magnetic Field, calculated as: B = µ0 I N / L

So, the very flow of Current (I), through Turns (T) at Length (L) with Permeability (µ0) determines the Magnetic Field (B)

Electromagnetic Induction states that the Magnetic Field B and the density of it is a dependant value of Electromagnetic Induction: E.M.F = dPhiB/dt

So there is a little bit of fiddling, getting the right Load, making sure the Magnetic Fields are as high as you can, but not saturating the core.

I hope this helps!

All the best

 Hi, Chris! I used your schematic, this one:

with the only difference that I used 2200 uF electrolytic capacitors and ultra fast diodes.

First I used the U+U ferrite cores shown in the previous posts. I swept slowly the entire range 3khz-65khz with sine wave input and I saw no magic frequencies. In the process I burned 2 LEDs. Then I switched to a 1.2 W light bulb.

I changed to E+E ferrite cores and and I made 15/45 turns. The ferrite is 3F3 and has a bigger inductance factor than the U cores(which are 3C90):

Again I tried to find any frequencies where the input drops and the output grows or at least stays the same with no success. Then it struck me a question: if there are 15 turns in the primary and 45 in the secondary, why do they look symmetrical(also in the VTA they look symmetrical):

I guess the secondary is wrapped first and 30 turns are placed on a core piece and 15 turns on the other core piece. Then the primary 15 turns are wrapped on top the existing 15 turns of the secondary. What do you think, should I give it a try? Any other ideas what I did wrong?

Thanks

Hi Cd_Sharp, Very Nice!

I think that the Currents in the Coils, the Magnetic Fields, are not opposing maybe? Can you check with a Scope?

I have a small Measurement Block I use, similar to the last ones I showed prior, but this is only to measure Currents:

 

With these, I can monitor the Currents in the Coils all the time. I can fiddle to get the best result. Maximum Current Amplitudes are about where the best results are obtained.

The Metal Strip Through Home Resistors are 0.1 Ohms (0R1) and are pretty good for this sort of thing. Very low Circuit impedance, but still sufficient to make a reasonable good measurement.

Recently, I did some experiments, where I had trouble getting the Currents to oppose, something very odd going on, I will show more on this soon. Electromagnetic Induction is Equal and Opposite, this is Lenz's Law, it is built into Electromagnetic Induction and will never change, so I need to try to explain why sometimes we don't get this Opposition!

Re Symmetrical Coils:

Yes, you can have Symmetrical Coils and because the Magnetic Field is NI/L the Field is Symmetrical with the Same number of Turns (N) and Current (I)!

But, please remember, if there is a situation where you use Symmetrical Coils, equal turns on each Coil, then there is always an offset of approximately 1/4  to the turns on the Primary, or Input Coil. Don Smith shows this very Clearly:

 

 

Don's Turns:

  • L1 = 4 Turns
  • L2 = 16 Turns
  • L3 = 16 Turns

Don regularly terms the Output Coils, Partnered Output Coils as a single Coil, normally only using the L2 label. I have found it best to deem this Coil in Two Parts, because each part of the Coil has two different functions.

I hope this helps

I did some more work on the coils, I have 160 turns in secondary and 51 in primary on the U+U cores:

Although I understood that wire wound resistors are not good for current sensing, I did a preliminary measurement until my precision shunt resistors will be delivered. I played a little with the input frequency and at about 18.48 KHz a strange noise appears and a strange signal shows up on the scope:

Chris, I guess this is what we are looking for, right?

Another thing I noticed without having a sensing resistor is that the power consumption of the circuit drops significantly having the LED on at about 29.5 KHz input frequency, but if I cut the input power, the LED turns off.

Chris posted this 04 April 2017

Hi Cd_Sharp - Excellent Work!

Viewing the Current Wave Form as you are, is handy to see where Current Wave Forms that are not your Input lay. That's right, this is the Goal! We want a Our Input Single Pulse to be seen, and then a Secondary Pulse or a series of them by means of Electromagnetic Induction!!!

Now all you have to do is isolate where these pulses are coming from, making sure its the Coils and not the Sensing Resistor or anything else. 

By viewing both Coils at the same time, with two sense resistors with the circuit above also helps. We should see Ecual but Opposite Currents, then we know we are on the right track.

Excellent Work!!!

All the Best

cd_sharp posted this 11 April 2017

Hi, Chris! I finished up the current sensing PCB. From the following pictures I believe that the voltage drop on one resistor is positive and the voltage drop through the other precision resistor is negative. I think this means the currents go in opposite directions, right? It's what we need?

Hi Cd_Sharp - WOW Excellent Work!!! Sorry I have been busy the last few days.

I think you are showing excellent results! You have proved several things, things that many others have trouble with.

  • Currents are Opposite, 180 Degrees out of phase!
  • Lighting LED's when in Resonance! A Load!
  • The basic Circuit works as we have shown!

Maybe try pulling more load by adding LED's and see what your Input Does? I would learn as much as possible here before moving too much further.

Ideally you want the input as low as possible. This may mean adding a few more turns to the big coil. By experimenting with these two parameters, Load and Turns vs Input Current this should show a lot!

CD, this is awesome work! You should be very excited! This is ground many cant get to!

All the best,

   Chris

 

P.S: Your Input, is it a single Pulse as I expect it is? DC Pulse to the Fet?

Chris posted this 13 April 2017

If I may suggest, look at your Gate on your Fet with one of your Probes. 

Make sure its turning off properly. It likely is, but worth checking. Then look at the Time of your Input Pulse vs your Output.

The goal if to maximise the total Electromagnetic Induction, for no extra on the Input.

You should get 2x Electromagnetic Induction at the Cost of 1x - This is the Action Reaction then Counter-Reaction thing.

   Chris

 

P.S: Aim to maximise the Electromagnetic Induction you already have going on.

Chris posted this 13 April 2017

Hi Cd_Sharp - Ah ok, yes I see. Try adding the Fet, use a Function Generator to pulse it. You will likely need the resistor, this will reduce the sharp DC Gradients/Pulses on the Coil and help to smooth, Sine as you have shown. Try different values, 1 Ohm, 0.22 or so. Same as on the schematic ( R1 and R3 ).

You should see a DC Pulse input and a Pulse Output which is Free - I have shown this many years back here: My Early Work

Excellent Work!

Hi Cd_Sharp - It may be worth a read or a quick look over at the real Inventor of these circuits, Akula only copied and replicated them from Andrej Melnichenko

Take note of the Wave forms (Flyback, Spike), and the ideas presented. Newton's Law's: Every Action has an Equal and opposite Reaction

We need to think in terms of Segments in Time, and what is happening in these Segments! For each Segment can contain Electromagnetic Induction, some where we have to Pay for this Electromagnetic Induction, and some where we do not have to Pay for this Electromagnetic Induction.

   Chris

Please Note: "Flyback, Spike" in it's self is not Over Unity, but this is a Segment in Time, where we have:

  • A Magnetic Field Changing in Time
  • Current coming back out of the Coil at 1/2 LI2
  • Two Coils Where the Magnetic Fields Oppose

All, at no cost to Us, this Segment in Time is Free, for Us to Maximise the Electromagnetic Induction!

 

cd_sharp posted this 17 April 2017

Hi, Chris! I read the above stuff and it all makes sense. I believe a variable duty cycle function generator is needed to try this multiple EM induction, right?

Unfortunately, my existing function generator does not allow duty cycle control and I'm thinking to order a more powerful one and it may take some time for the delivery.

I also noticed that Andrey Melnichenko talks about the air gap (the split) between the 2 core sections:

This sentence makes me think about the "Aspect Ratio" that Floyd Sweet wrote so much about.

I guess in our case the split is actually the distance between the 2 POC coils and there is no need for an air gap, right?

I also know from my previous experience that such an air gap can counteract successfully any magnetic saturation of the core.

Anyway, I will not be posting any more experiments probably for at least 2 weeks until I receive my function generator.

Thanks so much for all the help!

 Hi Cd_Sharp - You dont have to have a variable DC FG for this, it can help to get best results, but not necessary.

In the past I have used a small Microcontroller to do this Variable Duty Cycle and that has worked fine, so nothing expensive is needed,

The Air Gap is something I would reserve for later decisions, it can get complicated and confusing if one spends too much time with the Gap. I would stay on track, with what you have got as you already have excellent results.

If one wanted, one could even go down the path of using a "Cross Coupled  Oscillator" at the desired Frequency. Very simple and very cheap.

 

Of course the specified values would need to be changed, this was from a very old project of mine.

Hi, Chris! When you said to add a FET and a resistor is this what you had in mind?

I'll give this a try with some much bigger coils 73/220 turns and still keeping the 1/3 ratio.

Thanks

Chris posted this 27 April 2017

Hi Cd_Sharp - Sorry I wasn't Clear - No I meant the Resistors: R1 and R3

These resistors are set in attempt to round off the sharp voltage gradients on the coils - from the DC Capacitor Mosfet Pulse - To create a steady change over time of the Magnetic Field and which in turn creates a steady "Generation" of Electricity via Electromagnetic Induction. Notice the Switch SB1 is used to switch Off the Device, for this Coil is the Coil that keeps the Device Powered and the Interactions of these two Coils together that Pumps the Electricity back to keep C11 and thus C3 topped up if you like.

In the following Video, you can see the Resistors have been changed and one is soldered temporarily on the under side of the PCB:

 

Its worth noting, this work is exactly the same work as the Andrey Melnichenko Work, follows all the same principles even though the Circuit is different. Tariel Kapanadze also gives credit to Andrey Melnichenko for his work. Its all related, all works on the same principles.

Its worth noting, this basic Circuit is exactly the same as the MrPreva Circuit, the exact same principles also apply and you have already shown excellent results there!

Hi, Chris! I understand what R1 and R3 are doing. However, I do not know how to properly use my function generator and the MOSFET to replace the drive half of Akula's circuit.

Apologies Cd_Sharp, I did already think you knew the functions of the resistors. Yes please, you do what you feel best, your gut feeling is whats most important.

Mosfets are a DC Switch as you know, so a single pulse will only switch one way.

Take your time, if you're confused, Think on the Electrons in the Wire and what they are doing. How can we make them Move, and how can we make this process as efficient as possible?

What do Charged Particles do in a Magnetic Field? What does the Magnetic Field make them Do? If they have an Orbital movement, how can we manipulate this movement?

Hi, Chris! I know what a resistor, a MOSFET, a coil, .. generally do in a circuit. I've been investigating this field for years. I can't say I'm an expert, but I'm not a beginner.

I know everything that you made available, all your videos, documents, etc. I agree with you about principles and theory. I look up to you for a clear and practical path to making this work. However, sometimes I'm having a hard time understanding the practical part from your work.

For example, Mr Preva circuit you are using for showing the basic effect.

I do not understand what can be done with the simple test bed circuit. Is it supposed to be a simplified version of Akula's 30W circuit? Is it supposed to be used just to find the resonant frequency of the coils assembly? If so, can't the Mr Preva circuit be used to find the resonant frequency, just by replacing the coils?

Only after finding the resonant frequency is the correct time to build the full Akula 30W circuit and aim for that frequency?

I'm trying to understand this as a learning process before continuing the actual work. Over the years I had a huge amount of failures and I'm trying to avoid that.

Also, can you please take a look at this to let me know if it's worth a try replacing the full Akula 30W circuit? Thanks!

Hi Cd_Sharp, Yes I have built the same basic circuit, and yes any time we have the opportunity to learn a bit more it worth the effort.

If the DC power is permanently connected, then the Capacitor may not show a Discharge Time Constant, maybe a switch after the DC In. Charge the Cap then turn the Circuit on.

Hi, Chris! What do you mean, like this?

Yes nice!

A push to connect switch, so the Cap is not connected all the time to the Voltage Source.

The reason, you know already?

   Chris

cd_sharp posted this 05 May 2017

In order to allow it to run itself, to recharge the caps from the bemf of the larger coil, right? Up until now I was unable to find any truly resonant freq, but sweeping takes time. I did not give up.

Hi Cd_Sharp - Yes, sort of.

The Capacitor and Coil (L1) on the Transformer/Generator will have a LC Time Constant, this Time Constant will not be the same if the Voltage Source is permanently connected. The Capacity of C will dissapear. As the Voltage Source is constant.

So yes, youre right, there can be no Recharging if the Voltage Source is Constant!

It's good to know that. This explains why I found no resonant frequency until now.

Here I see a problem. In order to try to find the resonant frequency, I would need to repeat the following process manually: choose the frequency from the function generator manually, close the switch SW2 to charge the cap C2, then open the switch SW2 and see what happens to the load.

This means I cannot use the automatic frequency sweep that my new function generator is capable of.

I guess the switch SW2 would have to be replaced by an automatic switch, something using a transistor that switches off the power supply when the CAP C2 is full and switches on when C2 voltage is zero. Am I right?

@Cd_Sharp - Are your Turns Count about the same as the Schematic? A Turns Ratio of approximately 1:4 is needed, for every one turn on the Primary 4 Turns on the Secondary.

It gets complex, but the other way around also works, I dont want to confuse the device.

Yes, some degree of on off on off is needed. A little painful.

Hi, Chris! This is the latest work. I used this circuit posted by you, trying to resonate my coils:

and I connected my equipment like this to try to replicate the circuit above:

The results are amazing so far:

If I cut the power, the LED stays on for a few tens of seconds, so I must be getting close to the resonant frequency. I'm sorry I did not take a close shot of the scope, but I definitely saw a lot of output pulses between two input pulses and also during an input pulse. The fact that my power supply show 0.00 A means the circuit uses under 10 mA.

Chris posted this 12 May 2017

Hi Cd_Sharp - Again nice work, but, you have already done that, we now already know Currents in the Coils are opposing.

Resonating the Coils is not LC Resonance, we have seen the Work done by the Coils, this is Energy Generation when the Currents/Magnetic Fields oppose. Now you need to replicate the Pulsing with the Mosfet, that I posted to the main thread: Akula's 30 W lantern

Remembering, a small input can have a big impact on a device - The Input Resonance is not LC, you need to think more in lines of the Links I provided in the other threads now.

Remember the Mosfet is a DC Switch, it Chops DC, the Capacitors are acting as a Reservoir only.

Chris posted this 12 May 2017

Hi Cd_Sharp, any mosfet or Transistor with a good rating and a good Rise and Decay time will do, also a good rds on would be nice. a Common 3055 or a IRF3205 will be sufficent, just make sure its getting turned on and off properly.

No need for anything special or unusal, no need to order any Russian Diodes or Transistors.

Did you read the documents? Do you know what needs to be done? the Pulses?

   Chris

cd_sharp posted this 12 May 2017

Did you read the documents? Do you know what needs to be done? the Pulses?

Yes, partially as I have limited daily time for this. A very small duty cycle square wave must be used to hit the frequency where the time between input pulses are completely filled by a continuous pulse on the output.

The antenna stuff is really new for me. All the other information is basic physics: voltage, current, charge, resistance, Lorentz Force, Lenz's Law, etc which are really just a theoretical model that fits in for now.

I worked back and forth with the Akula No 4 circuit video trying to understand how to resonate the coil(s). I'll talk about ESR and not LC resonance, as Chris explained that this is what we are looking for. This is the most important shot:

I believe it's clear that Akula uses just the big coil when finding the ESR frequency. On the right hand side there are at least 4 coil endings which look like they are not connected to anything, they are not powered and not shorted out, they are open.

So, I guess this is the ESR circuit:

It looks like LC resonance circuit. The action is our input signal through the big coil, the reaction is the back emf spike and the counter reaction is an echo of the back emf spike that only happens at a certain frequency. This is what Chris discovered.

@Chris, am I correct?

cd_sharp posted this 26 October 2017

I worked a little these days on this project and I definitely can say that it's easier for a beginner like me to research a small coil (20-30 turns), like Akula shows. I came to this conclusion after I played quite a bit with the setup above (206 turns).

I watched closely Akula's video, and it looks like the pulses are under 5% DTC.

I can tell you that lately I was surprised what you can see on the scope pulsing just 3V and 1% DTC in 20 turns. I need time to understand and document what I'm seeing, and I will do that.

cd_sharp posted this 23 December 2017

Hi, everyone! I didn't quit on this one, I have it on my desk and I promise I'll come back on it in January 2018 because I'm intrigued by what I saw back in October.

cd_sharp posted this 17 January 2018

I'm back on this one as I promised.

My first thought is it's very important to know the duty cycle Akula uses. It can be calculated:

The time per divison is 5us and pulse duration is about a fifth of a division. So, the pulse duration is about 1us.

Since we know that the input frequency is about 250Hz, the period is 4ms.

So, DTC = 1 * 10^-6 / 4 * 10^-3 = 25 * 10^-5 = 0.025%.

If you see any mistakes in my calculations please let me know!

Anyway, from watching the video it's clear that Akula uses extremely low DTC.

Zanzal posted this 17 January 2018

Wow, great work there. And yes, your calculation looks good to me (1us / 4000us)*100% is 0.025%. That's very interesting. I don't think I ever tried an Akula replication with such unusually low duty cycles. I'll have to re-test my old circuits now.

I've made a couple of replicas with different schemas because I do not know what is the correct approximation. Most important is a good toroidal transformer and the correct number of bends and this is a nice winding (15 turns no 17, etc). .

Hey Eureka. Sorry to hear your replications aren't quite there yet. I myself had trouble getting the timing circuitry for the TL494 to work. I did find some anomalous things that have kept me interested in this circuit. Wish I could say more, but I am not far enough along and I don't want to lead anyone down the wrong path on this.

Hey Eureka - Steps forward is always good!

The Input Current is not impeded by Output Current? If loading the Output Increases the Input then its not quite right.

In The Mr Preva Experiment, we see an Amplification of Current, the Current is "Generated" by Magnetic Field Opposing each other, changing in Time. 

Flipping the Output Coil Polarity should fix the problem. Increase Turns on that Coil, and adjust the Input Frequency and Duty Cycle. Once you find the Coils Magnetic Resonance, which is shown how to do in the Mr Preva Experiment, then this will work.

Remember, Turns is Voltage, Current is Field Opposition.

With a little work, this does work, the Schemes are correct mostly, its a case of fiddling,

Thanks for Sharing!

P>S: Thinking in terms of Magnetic Resonance - Not DC Pulsing as a Sine Wave

This might sound a little out there, and may not be an entirely correct way to think of this, but, Imagine a piece of Wire, it has a length equal to X - 10 meters as an example.

The length of wire is the Length of the Orange + Green portions of the Sine Wave, we are viewing the wire as a Wave, like so:

So, the Orange length is 10 * 0.25 = 2.5, and the Green portion is 10 * 0.75 = 7.5 and we have 2.5 + 7.5 = 10

The Red marker is the point where the Wire length is Centre Tapped, this is the point where we switch in out In Pulse. Typically a Diode(s) is placed here, to stop Electromagnetic Induction at the wrong time.

The On pulse must be short, have the right Duty Cycle and Time Constant, measuring the Input Current can determine this if necessary. You can get an idea by viewing the wave, Approximately 0.25 or 25% Duty Cycle, the Current ramps similar to the shape of the Orange Wave Form. We have Maximum Magnetic Field for the Input Power Supplied, now its time to Use It...

Then, with some fiddling, following this sort of idea, making sure the Input is not loaded when the Output is Loaded, you will see gains in Electrical Power, "Generated" by means of Asymmetrical Electromagnetic Induction.

We must force our brains to think about Electromagnetic Induction and not allow Brute Force to take over. Inducing Currents is the Key here. Magnetic Resonance.

Hi, Chris! I think you wish to make us think about using Electromagnetic Induction as a mirror, to reflect a wave such that it adds with the wave that produced it.

However, I don't quite understand how to practically apply the relationship between the length of the wire, wavelength, frequency and DTC. I'll keep thinking and reading.

There is a big question in my head: why Akula used 0.025% DTC with frequency 256 Hz for the length of the wire he is using. How did he come to these numbers?

Hey CD - Coils, Currents, Magnetic Fields and Time are all related - This is Electromagnetic Induction.

One Quarter Wavelength, λ * 0.25, or 25% Duty Cycle of the Current Wave Form is Peak Magnetic Field.

Three Quarter's of the Wavelength is also Peak Magnetic Field, but this is irrelevant, its not used.

In a DC Circuit, the Current in a Coil takes time to reach its maximum, this is normally 5 Time Constants, at this point the Magnetic Field is also at Maximum for the Voltage applied.

Keeping the Voltage applied any longer than this is not bennificial if one is only requiring the Magnetic Field.

The wave length and length of the wire have a relationship, now I am still learning so I encourage you to cross reference and check what I say, but, Energy, if impeded by a Miss-Matched wavelength, will reflect and as a result less power will be available on the output:

 

The above videos are meant to tie in with the Picture I posted:

 

I know your calculations resulted with a figure of: 0.025, there may be a harmonic used at this frequency, but the concepts apply. Remember, Akula was a Radio Electronics man, I think something like 9 years in the Radio Electronics arena. So he knew all about this stuff.

Others, Floyd Sweet and Don Smith, no doubt more, knew about this also.

  • Magnetic Resonance

The Coils can be bought into Magnetic Resonance the same way an Antenna goes into Magnetic Resonance under the right conditions. Treating our Coils like an Antenna is beneficial, this is an Efficient way to bring our Coils into Magnetic Resonance, to "Generate" an excess Output.

With a Peak magnetic Field, we can then expect on going effects after we have switched off our Input, E.G: Collapse and further Electromagnetic Induction.

P.S: We saw this importance of Magnetic Resonance, in The Mr Preva Experiment.

Hi, Chris! The wavelength concept and formula for antennas is clear for me. However, I don't understand the wavelength concept for transformers. How does this formula apply to transformers or coils to calculate the wavelength?

λ = v / f,

where v is the speed and f is the frequency.

Hey CD, Transformers use Impedance Matching theory and in our work we extend it a little, using the concepts in Antenna Theory.

I have a reasonably detailed explanation and use of the concepts here: Antenna Theory = Magnetic Resonance

Hey CD,

This is awesome work! Clearly a very efficient system!

Gate Voltage to the Mosfet can sometimes be enough to keep a system running. For this to happen, a very efficient System must be in place first!

We need to ensure that the Electromagnetic Induction occurring in the System is sufficient to replace Losses and a little extra for the Load. You have all this knowledge already, via previous experiments.

In the Gunderson MIT, the sharp pulse seen in the below image:

 

 

is where the magnetic Fields are Slapping together with immense force! Total Flip in polarity in the Current in this Coil! The Polarity on the other Coil does not Flip, change polarity! 

Because this is very fast, it "Generates" a High Voltage. This Voltage is due to Faraday's Law of Electromagnetic Induction:

E.M.F = -N dΦB/dt

At this time, as we have seen in the other experiments, we have several conditions being met:

  1. Magnetic Field is at maximum, moving toward Zero.
  2. Partnered Output Coils Magnetic Fields Oppose each other.
  3. Using the Right Hand Grip Rule we can determine the direction of the Magnetic Fields.
  4. Currents are also in opposite directions.

From all our experiments, we know its just a case of increasing the parameters to get the Voltage up high enough to exceed threshold Voltage for Unity. Because our Magnetic Fields Oppose, the Current also increases.

Your work is superb CD! Great job, thanks for sharing!

Guys, I believe I have replicated this wave form with a single coil and single capacitor, just like Akula shows:

I kept only the first big capacitor in the schema. This is the first time I obtain this resonance on a single coil:

This looks close to what Akula shows, starting from minimal duty cycle and increasing it just a little to a value under 1%.

So, the coil-capacitor pair has become a current source for 99.5% of the period.

Hi, Chris! I'm focusing on Akula Lantern No4. All the schemes I've seen are far from the circuit shown in the video. For example, using the grid overlay:

  • VD4 diode is in the video at O32 (anode) and O25 (catode) coordinates, but VD3 is not visible in the video at all
  • C28 is not 1000 uF, it's probably 467 uF and it does not look like it's anode is on the output rail. It looks like it's catode is connected at K17 and anode at I17, which makes it parallel to C35, the main capacitor.
  • R53 is not 100 Ohms, more like 6.8 Ohms

I learned not to trust any circuit scheme coming from someone unknown.

I know you are talking about principles and I thank you for the help. You have a point definitely, it's proven.

Recently I noticed that all the working lanterns use white or blue LEDs. Could it be that the fact that they have a greater forward voltage drop make them delay the current as we need, like a varistor?

I think it's very important that we try to draw, to reverse-engineer correctly and honestly this circuit.

Anyone wishes to help?

Hey CD,

You have many good points! I back engineered the circuits I have done for the same reason!

If I may say, I am sure you already know, the Circuit only has to produce the same signal as the FG produces. So a lengthy engineering project to find you need another circuit may help learning Electronics, but may not result in what you require at the end of the day.

Question: have you recorded all the parameters of your current setup? Inductance, wire length, turns, Frequency and Duty Cycle, Cross sectional Area of the Core, all this stuff?

Your work is superb, I will help with this back engineer, lets make this circuit a simple one for all to follow! Again it will not suit all...

Hi, Chris! Thanks, man, you did a massive effort.

I don't believe we need the exact same inductance, number of turns, core material, core area or wire length Akula uses. I wound L1 just to cover the core with one layer.

Wire length ratio is very important, I'm currently using a 1:2 ratio, very precise. Duty cycle is the most important thing and I believe I replicated it. The frequency is in the same range Akula uses.

It bothered me that VD3 is not visible, but then I replayed slowly the low quality video:

There is something in there that I missed.

Could be the anode of a diode, the missing VD3. Let's see from the top.

It's a diode, barely visible.

Hi cd I'm glad about your progress, and would like to add some information that hopefully will help. I would agree with Chris that the most of the circuit can be performed by a SG, but the switching stage is important.If there is a longitudinal wave present as I believe, the pulses have to be short, strong(capacitor discharge) and UNIDIRECTIONAL.No reversal bouncing after the pulses. The energy is captured by the coilset. I wish you success, Vidura

Hi, buddy.

That's what I'm trying to draw, a circuit that uses a function generator instead of the TL494 based circuit. I already used a function generator to replicate the PWM (0.5% duty cycle - the magenta trace) and LC time constant (the blue trace) Akula shows.

I have no doubt a function generator can do all the needed PWM. L2 we know, the currents directions we know. The only thing left is the output stage which became pretty clear.

Hey Guys,

Akula used a Diode configuration that was not only intuitive, but also a clue as to what to look for. In Electronics, we have a Silicon Rectifier that contains two Diodes back to back:

 

Akula had this same idea, but one Diode in reverse:

Where, D1 and D2 are Half Wave Rectification of the L2 Coil. You can see this configuration in all of Akula's Circuits:

 

 

C2 is marked in the above diagrams as: C2, C7, C3, and C28, this Cap powers the Output LED's and acts as a ballast Cap for the Input, C1. An interesting arrangement, as the Currents as we know can flow in more than one direction, Positive and Negative Flowing Currents!

I hope this gives others some food for thought!

Please, let me know if you see any mistakes. I found the grid overlay very helpful, I recommend using it.

I tried to attach it in full size to this post, but the Attach button does not seem to do anything.

Anyway, D5 diode is the hidden one and it's probably connected at N20 (anode) and N16 (cathode). Otherwise those connections would be completely useless.

You're totally right with this Jagau. I haven't seen it this way, and the output from the boost is partially fed back thru the second coil. @CD It might be a good idea to use the same arrangements of the diods between the transistor and the coils.

A Boost converter can be up to around 96-98% efficient. Whats required to get over this Efficiency?

Indeed Chris where does this energy surplus come from?
An incandescent lamp of 60 watts gives about 850 lumens which is the equivalent in lumens for the 10 leds which draw from the source 6 to 8 watts on 12 volts. That's why he wrote 60 watts on his schematic.

Surely it happens in the second part of the diagram. The second coil of 45 turns extract energy by 2 times depending on the phase of the coil, this must be experimented. But I do not see where it accumulates, at least the way the circuit is build maybe have some correction to do?

In fact it should recharge the first capacitor C6 has a value higher than C7 given that it becomes the source, nice experiment to do CD will try it with you.

Hey Jagau,

You have hit the nail on the head my friend!

In The Mr Preva Experiment, we saw Currents travelling in two different directions from Coils that had a singular Voltage Polarity:

Timing is critical, we have to Charge the Primary Capacitor at the right Time! So, the small sharp pulse on the Input is the Catalyst, removing a tiny amount of charge, the Diodes ensure we have the Current Charging the Primary Cap at the right Time, at the Inductive Collapse. More Turns means Voltage is stepped up, and because Currents Oppose, we see a step up of Current also.

In the following Pseudo Circuit, we see The Mr Preva Experiment, but with a little more components. The Diodes indicate a very simple concept, that is, of isolation!

 

The Input is completely isolated from the Output, we have the ability to create as much Magnetic Field as we wish and the Input is not affected at all by out Loaded Output Circuit.

Watching carefully, the Current, the Polarity on the Capacitors and the action on this basic simulation gives some idea:

 

Its a Feed-Back Loop that forces a response, a static "Generator" of Electricity!

Here is revision 1 of the circuit, this schema:

and 2 videos with it in action (voltage at the base of the NPN transistor is magenta, voltage at the collector is blue and voltage at L2 start is yellow):

and

I disconnected C2 and D2 because we have the PWM stage using the function generator.

I'm sure you can see the same phase difference we've seen in the MrPreva Experiment.

However, there is something wrong with revision 1 circuit, I missed something important because the blue trace is decaying very slowly and after a few tens of seconds the yellow trace is also decaying.

Back to studying the Akula's video. Please let me know if you see any mistakes in the revision 1 circuit!

@Chris this seems to be close to the experience of Mr Prevna. The only problem is that the resonance with a pulsed DC is difficult to realize when we have diodes in the circuit, they prevent the free circulation in both of the rapid exchange of voltage and current that we either LC parallel or serie. But there is nothing impossible it requires a little more experimentation,this is my opinion I think rather a mixture of two frequencies that will increase the recharge of the system .


@ CD sharp yes I think the best starting line is the one Chris just passed on in his last tube. I started to experiment on this very interesting subject and it seems that I can still learn a lot, we stay the course.

You guys are breaking ground that has not been broken by all those preceding you! Awesome Work!!!

Hey Guys,

If you look at Madsatbg's progress, the first thing you should notice is the change in Wire Size:

From Thin Wire, lots of turns:

 

 

To, thicker Wire less turns and shorter lead lengths:

 

 

This was one of the big changes seen in the videos. This gets the "Generated" Energy to the Capacitor with least Resistance and losses. This reduces the decay rate, and the rate at which the Capacitor charges is greater than the discharge.

I hope this helps some!

Sorry I was generally speaking, but yes. The Charge Cap , in the Circuit, C1:

Must have a Charge Rate greater than the Discharge Rate to stop the decay rate. This means playing with Coils, turns and wire gauges, also the Frequency and Duty Cycle.

So, L1 needs more turns and thicker Wire than L2, normally a factor of 2 or more, approximately. 2x Turns and 2x Wire gauge, or there-about's. Some fiddling is required.

Friends, this is revision 2 of Akula Lantern No 4 and I believe I know how this lantern works.

The switch is IRF3205, so it draws very close to zero current from the function generator.

Here is how to tune it:

L2 and the LEDs are forming a RLC resonant circuit which "likes" some frequencies where peak-to-peak voltage is highest. So I thought to help it, to give it what it wants, such that it oscillates longer.

So I added C2. In the beginning I thought that the value can be calculated, since I knew the target frequencies.

To my surprise, the resonant frequency of the L2-LEDs tank changes depending on C2 value. I can only think that the capacity of the LEDs changes also during current flow.

So, I could only think to try different low value capacitors in parallel and watch the traces. The goal was to make both traces oscillate as high as possible and for as long as possible, The MrPreva experiment effect N-times repeated. Thanks, Chris for pointing the importance of this experiment and for many other important concepts you shared, like the one that a LED has capacity.

The next step is to make the 7414 based driver circuit and replace the function generator.

It's hard to grasp exactly the connections from the photos. Also, it's impossible to see the component values Akula uses.

Since the driver circuit has to be powered from the secondary capacitor (the green one) when the battery is disconnected, we need to take this into account. The voltage on PIN 14 must be kept steady.

We also need very low duty cycle values, under 0.1%. Actually I think this is one of the important facts that make the device self sustainable. My function generator cannot go under 0.1% duty cycle, that's why I think this is the best that I can do without the driver circuit.

I don't have an electronics background. Anyone willing to help with this?
