Wow! Can I have the winding details of your coil.  ;)

Sure. I used a ferrite core from a TV flyback transformer. Made in China, no doubt, which is on the same land mass as Russia.

I made a bobbin using a brass tube for the center and a couple of plastic discs for the ends. The tube fits nicely over the ferrite core. I then soldered one end of some #27 magnet wire to the brass tube, and wound a bunch of turns onto the form. The inductance of this winding is about 6 milliHenry. Then I took some aluminum duct tape and wrapped that around the first winding, electrically connected it to another piece of #27, and wound the second winding over the aluminum tape. This second winding measures something like 24 milliHenry. Then I put another layer of blue masking tape on the outside.

To get to the stated values on the schematic I would have to use a much bigger coil form, or much smaller wire, neither of which I have on hand. But Akula showed this setup working with just a few turns of heavy wire on his flyback ferrite, I thought.

To avoid confusion.... don't even _think_ about testing your circuits with a small battery to see how long they will run! That would just be trolling!

Just for that, now you have to watch this.

It was always obvious that a button cell powered boost converter can power two LEDs for a long time.

...but what was that thing at 8:30 ?!

Я не утверждаю, что так как у меня -правильно.... Напротив я за поиски нового, так как не получилось выжать больше чем на видео. :-\


Я думаю на сердечнике из титаната бария попробовать, у меня были хорошие опыты с ним. ;)
Я пробовал, как только мог, самозапит не получаеться, мне было бы хорошо хоть какой самозапит зделать, поэтому информация, сколько витков было на какой катушке, было бы хорошо и ленты медные замкнутые или не замкнутые знать бы.

It is the ground of the probe. You see him disconnect it later on in the video. The ground on the other probe is not connected!

He also has a lead plugged into the external trigger on the scope.
on rigol scopes the ground is not isolated, so connecting one is the same as connecting both.  (and most inexpesnsive digital scopes)

This is not best practice and can give anomalous readings. I'll leave you to find out why, as I'm not here to enter into a discussion on how and how not to use a scope. I accept that its unlikely to make much difference in this particular case, given that the circuit is already full of anomalies!

Obvious to you and me perhaps, but evidently not so obvious to a lot of other people.

.... and haven't you ever seen a Naked Troll before? ....

Very true all of that.

The circuit does have substantial HF components in the signal though, because of the fast rise and fall times of the output of the MC34063, and is radiating a tiny little bit of power in the RF, so for quantitative readings, and to assure isolation from mains pickup, the probes both should be properly grounded of course.

I suppose I should explain the alt.snakeoil Video Report.

Stefan left a comment on the video and I replied; I'll repost it here just for the record.

Stefan said,

Hi TK, so where did you hide the battery ?
Where do you think Akula hides his battery in the Latern circuit as he shows at the end, that no capacitor contains a battery...hmm, do you think he has cut and pasted his videos and exchanged parts during the edits ? His last videos seemed to be filmed in one go though....hmm...so where do you think he has hidden something...?

And I replied,
Quote
It's a single CR2016 flat coin cell, just taped to the underside of the board and connected by short bits of magnet wire, making contact when the weight of the board presses them together. The battery is smaller than a US quarter dollar coin and as thin as a dime. The thing ran all night long with brilliant LEDs, over eight hours, on that little battery. It finally stopped running when the battery open-circuit voltage was about 2.6 volts. The MC34063 chip is amazing and very versatile.

In some of Akula's videos the board has several potentiometers, and two, but not all, of the pots have their cases soldered to the ground rail of the circuit, as Hoppy discovered. It would be very easy to put batteries inside the cases of these dummy pots, making contact with the case to the negative pole and running the positive out one of the three regular potentiometer leads or with a tiny wire invisible on the video..

Recently we have seen a video from someone else, who demonstrates power wires that are just very thin magnet wire. Smaller than #30 or #32 can't be seen in most video resolutions.

I'm still trying to figure out how to get the precise waveforms he showed, with the spike train and the sinusoid. The chip in my build makes some strange waveforms, it is true, so maybe I just haven't gotten all the parameters right yet. I'm not ready to dismiss the waveform as fake. I think most of Akula's circuits work just as he has described and demonstrated -- they are proper Red Herrings -- and the only thing I think is faked is the running without outside or stored power.

Thanks for watching... and for not "dissing" the demonstration!
(The installed battery can even be recharged quite a bit, by hooking up the external power supply for a few minutes.)

Am I wasting your time? Sorry. Just put me in your "ignore" list and keep on trying to get Akula's circuits to work as he demonstrates, then. Please pay no attention to my demonstrations, since they are wasting your time.

I am doing just exactly what I believe in, which is to examine claims of overunity performance, using the best methods I have available to me. If I can't get the claimed performance, no matter what I do, using the exact specifications of the claimant, but I _can_ get the claimed performance by a simple conjurer's trick... I am tempted to draw certain conclusions from that. If nobody else is able to get the claimed performance either, no matter what they do... the temptation gets stronger and stronger. Meanwhile I will keep reporting what I find from my testing, and my time is my own to waste, mostly.

So now I've tried a TIP3055 transistor (thanks Bill!) instead of the IRF3205 mosfet. The TIP3055 does switch and produces another set of different waveforms from the circuit. But with the heavier inductance on the 34063 chip side and the lighter inductance on the transistor side! And as usual phasing is important, I get different waveforms with swapping phase on one coil. Tuning (setting the potentiometer) has a great effect just as expected, since it controls the amplitude of the chip's output oscillations.

But whenever I pull the outside power, the system reverts to straight DC drive, keeping the LEDs lit for a few seconds on the stored energy in the big capacitors.

I forgive you my wasted time :)
I asking you what is your reason to waste your time?
Despite the using the best methods you have you can not prove that Akula's device isn't overunity.

Why should TK, or anyone for that matter, have to prove that ANY device is NOT overunity?  As we have all said on this forum for years now, it is up to the claimant to PROVE his or her device works, not up to others to disprove it.

TK has been attempting to replicate one of the many "claimed O.U." devices from this person.  When he sees that it can not work as advertised, I believe he then begins to think of the many ways it could have been faked.  Remember Mylow?  When TK suggested that he might be using fishing line, he was attacked but, as we now all know, TK was 100% correct.  TK has good instincts along with a wealth of knowledge so, I listen to him.  Maybe you should too?

As long as I have blinking lights, spinny things, and multiple oscilloscopes going on in the lab, my housemate thinks I'm doing something productive, and she leaves me alone. Otherwise, I might have to wash the dishes or clean the bathroom or something.

Right, I can't prove Akula's device isn't OU. I can prove that mine isn't, though, and I'm trying my best to make it functionally identical to his.
It all boils down to what Pirate said: it is the claimant's responsibility to provide enough evidence to support his claim. So far, we are working with the spotty incomplete and error-ridden data that Akula has provided, with Wesley's much appreciated help. But it really isn't enough. So I'm exploring the problem space.

You might better be asking "why does Akula waste everyone's time with partial information and inconclusive demonstrations.... when he should really be working in a secret military lab making fuelless power supplies for Russian submarines and spy satellites?"

I know why.... and I think you do too.
