if nobody else can replicate this then is concept same as acula device

my replica-NOT WORKING
does anyone made some working replica??

Hello everyone, this is my small contribution to this issue, I found interesting results with simulation, but in real life, I could not replicate the circuit that you raise, definitely an oscilloscope and a signal generator is needed for testing .

Have any of you had success with this proposed circuit here?

What interesting simulation efect you are talking about .?
Btw my replica of circuit is not working.

Dear fellow blind replicators,

Welcome to year 2016.

No offends intended but straight to the point since everyone before me failed in understanding what the original or reverse engineered Akula circuit is actually doing which looks simple for anyone to see and laugh at.

One fine evening during month of December i took a look at the Akula 0083 Dual TL494 for the first time.Since i got no plans ordering random electronics parts during holiday season for other projects.

Since i was researching into BEMF recovery i was amazed at what the circuit was trying to do at a glance as you folks once did.

Further research into this simple looking circuit revealed the pot leading to pin 1 of TL494 was actually connected to positive rail.Below 5volts at pin 1 that PWM generator turn on.

But but did anyone once find out that pot was connected to positive rail and the narrow square wave form from other I/C was actually creating spikes in the positive rail via the diode SF56 used for Back EMF recovery.

This spike is now causing the PWM i/c which keeps getting triggered.This TL494 with 3 pot i/c now produce series of interrupter pulse similar to a waveform of a  tesla coil circuit.

The output is a trumpet waveform at the flyback core .Heard me right a trumpet waveform once the frequency is high enough.

Lastly i think all of you failed to look into.By merely looking at how twisted the electrical cable looked for the first time like said.

I had very strong suspicion that Akula used drill to twist all the 3 sizes of electrical wire(Longest winding i'm using 2.5mm sq,1.5mm sq for the top layer which is half way winded.Both wires Multi strand.But for output i got insufficient info for the thin 1mm wire.I can't tell if it's solid or stranded.I'm merely using solid version for now)

To twist electrical wire simply tie one end of electrical wire connect it to a bench wise and the other end of wire to a battery operated drill.
I think the twisting action is intentionally done for these electrical wires to increase the skin effect/surface area somehow.

(Now i can't tell if Akula did the same for the kapandze winding. .But do take note)

I am too lazy to show a video base on a original circuit which is already available in this forum.

The key transistor used IRF540 for interrupter circuit with 3 pots and IRF530 for the Low frequency i/c.

But my version i'm just using 1 i/c 74HC132 to demo the circuit since i do not have a suitable pnp transistor to properly drive the mosfet original TL494 circuit at this moment.

The waveform is attached and the current reading to show 0.00 but it is actually hovering around 10mA at 7.50volts.The voltage across leds/pwm circuit is nearly 11volts as obtain from the diode used for BEMF recovery.

This is the latest discovery base on experiment conducted only yesterday.
The only thing missing is the IRF530 which is not used yet for the pulse generation base on current setup.This once implemented will act as a important kicker pulse on top of the trumpet waveform.
Design is being improved as i type since none of this circuit is stored in my "online" computer.It is also created in my head a mini logic lab.


I will not waste my very valuable time in answering question base on answers which was already pasted in this forum before me in this topic.

Yes i am building up my personal credential for my future if there is no WWIII.

This might the only update from me for this topic.It might also depend on how competent you folks are.
