Hi Enjoykin,
Ferrite cores in the image above can be found or purchased from? You can tell measurements Kohm / cm on a clean surface of the core. . . this is just a little comparison, the core that I'm there. . .

Thanks

Hi havuhung.  :D

Ferrite cores can't be purchased from nowhere !! It's old П-type Soviet Ferrite.

Measurements absolutely aren't important to you. Every Ferrite core will work when is perfectly tunned. Internal structure of Ferrite is what is really important - not dimensions.

Try old Ferrites from old TV CRT monitors, old TVs,, from old PS or microwave ovens. !!

OK, so I found some heavy Litz wire on an inductor from an old CRT TV set, and so I used it to rewind my "primary". So that takes care of that.

And... it did make some difference in the waveforms. I get higher voltage peaks now, and some little differences in shape and frequency. I also discovered something very significant... and I'm now able to reproduce the performance in the video, keeping the LEDs lit with no battery connected to the circuit.

No tiny wires, no concealed battery connected to the circuit, none of that. But the Objekt is NOT a self-runner. There is a secret...

Hi TK. I guess in your case you are using something like a tesla coil to wirelessly power it?
All the best..

@Enjoykin:

Are you absolutely sure about that?

It is definitely true that standard markings for ceramic capacitors use the last digit as the exponent.
So capacitors marked "330" are 33 pF.
That is, 33 x 100 = 33 pF
"331" means 330 pF, that is 33 x 101 = 330 pF
"332" is 3.3 nanoFarad, that is 33 x 102 = 3300 pf or 3.3 nF, etc.

Do you have any evidence for the "330 pF" value of those capacitors?

Hi TinselKoala

I know perfectly markings of Russian and Americans standars of electronic components. :D

About cap.value. It is strictly dependant on particular ferrite. If you tune cap.value exactly at Ferro-resonant points of one ferrite - it will not work on other ferrite unless you find exactly right value.
Put variable capacitor/s in parallel to fixed one and adjust untill you get self-runner. If you know electronics excellent you can do the same with voltage controlled capacitors - varators.

About Litz wire. Make own litz wire. all you need is Electric Screwdriver and bunch of enamelled magnet wires - for example 0.25 mm2.

conclusion:
As i said in my earlier posts - circuits are very simple but extremely difficult at tunning. Ferrite need precise PCM modulation both LF and HF freq. with right ammount od Duty Cycle for each. All these parameters need to be found experimentally. Because that i clearly said everybody - don't try this builds if you haven't 2 channel oscillograf and 2 signal generators. And lot of nervs.  :)

Hi Enjoykin. What do you mean by 'NF'? HF is usually used for 'high frequency', but I don't
know what you mean by 'NF'.

wire is litz wire, capacitor 330пФ (330pf) p=pico.



Hey eugene900 - Do i see newest upgraded Rigol DS1054Z or is it Mirage ??  ;D

yes new rigol1054z upgraded to 100Mhz  :)

@eugene900:

Your scope isn't triggering properly! And you can save a screenshot to a USB thumbdrive in the front jack simply by pressing the "print" button at the top right...

ok ill tr next time.
If you make working without batery but say there is a secret -so what is secret?

Good. Others may not know, though, and you can believe me when I tell you that people have made this kind of mistake-- many times-- on this forum before. As I said before, do you have any confirmation that the capacitors are in fact 330 pF? Can you show the actual markings on the capacitors, or a measurement with a meter? The LariMan circuit is running at a _higher_ frequency with the installed capacitors than mine is with my known 33 pF caps.... does this not seem strange to you? Either his ferrite produces much less inductance/turns than mine, or his capacitors are small, or both.... yes?

There are no variable caps or varators on Lari-Man's circuit. Do you think he took a bunch of capacitors and just tried them all until he found the "right" value, or made many experiments taking turns off or adding turns to the coils, to get the "exactly right" value?

I know perfectly constructions of home-made Litz wire! Such wire that I have made can be seen in some of my videos. However it's easier to get it simply by stripping some off of all these otherwise useless inductors removed from old TV and CRT monitor chassis, as I have done for my Objekt.   :D

And yet... there is no evidence of such modulation in the Lari-Man scopeshots. He displays a single frequency with some jitter (when he manages actually to get a relatively stable display on his scope.) There may be two different frequency sources (the resonance of the coils, and the pulse frequency of the MC34063 converter chip) but they are clearly synchronized at a 1:1 ratio in the video. I've seen this same synchronization at certain settings of ferrite gap and external magnet bias in my own Object013b apparatus... but it still didn't "run itself".  I've also duplicated some other circuits using this chip, right down to the dual-frequency PCM or "burst oscillation" behaviour, and they still don't "run themselves". For example: http://www.youtube.com/watch?v=kHAc7kDY4-w

You've made a lot of statements that make it sound like you know how to achieve the self-running. Where's your evidence, though? Are you the originator of this circuit, the "Lari-Man" who posted the video? If not, do you have some self-running circuits of your own that you can show us? Some kind of actual empirical evidence for what you are saying? As I hope you can see, I show my work --  most of it, anyway  ;) --  and I'm not afraid to perform actual experiments to support or test my opinions and my statements.

Careful tuning, just as Enjoykin says. But tuning to what, exactly?

Hi TK, well done!  I think the 'secret' might have something to do with a beaker of water and a ring connected to a small light globe that lit up when you dunked it in the beaker?

By any chance is his device tuned to a HF induction hotplate cooker under the table?

Is yours tuned to some external source of power oscillator?

My guess is that TK has "tuned" his circuit to a local radio station freq.

Is there a prize for the correct guess?
