there is what we see on Akula's scope:

I think you are wrong. The burst oscillations from the MC34063 chip can be made very easily _with no core at all_ in the coil set.

I just now generated the scopeshot below, by completely removing the core and placing it on the other side of the table from the coil set, and slightly -- very slightly -- retuning the trimpot (which is a 20-turn trimmer, and only needs to be turned 1/16th of a turn or less).

My ambient EM is at my mains frequency of 60 Hz. Akula's circuit is picking up and responding to something in his environment that is making the 270 Hz signal that the 34063 is responding to.

                        @ TinselKoalayou are trying to get money from the bank but you don't know where they are. you are trying unlock every doors even toilets doors. you are still too far from the safes doors and you don't know the code of its.
you need to know what Akula was speaking in last conference on the skype:

http://webfile.ru/63bd3cd22caa0cb0343e3c0c52158678

Please save it and try to translate, it contains important information.

Isn't that where he admits that he couldn't reproduce the "self running" effect outside his laboratory?

I think I probably  know more about this specific circuit than you do. Since most of what you have posted is wrong. GigaHz resonance? Give me a break. None of Akula's constructions are capable of doing anything coherent at such high frequencies, so I think that you don't know what you are talking about.

You can actually hear the resonance in his circuit and it is probably such
a dimensional resonance as it is spoken in this Ferrite core PDF file that was just posted..
I just read it.

TK also has such a MnZi core with its low resistance of 50 Ohms/1cm.
These also have these dimensional resonance effects, so the core
is probably right...

Well, maybe you can tell us exactly what Akula said in this Online session ?

in the used circuit, which is a really strange switching circuit
http://www.overunity.com/14524/3v-ou-flashlight/dlattach/attach/137522/
the lower sine frequency comes probably from the secondary coil with the 100 uF
as LC tank which pulls down the supply voltage via the Q3 MOSFET and thus
switching on and off the DC2DC converter chip MC34063.

No, I no longer think this is how it is working. The sinus is created by the oscillation/noise bursts, not the other way around. Please see my earlier posts and the #11 scopeshot above.

Maybe he made an error and wanted to have the the DC2DC chip running
all the time...
As the ferrite core rings at around 8 Khz probably the spike frequency is around
this 8 Khz frequency with this low sine wave modulation or better said chopping it...

In this video he shows the scope shots:
https://www.youtube.com/watch?v=Lpx1SJdXnmo

I wonder why TK does not have the underlayed sine wave, where the spikes occur on the yellow channel....
Maybe he must avoid full dimensional resonance that shatters the core sooner or later ??
So he tries to change the spike frequency around the resonance frequency like a FM modulation ?

Regards, Stefan.

Didn't you see all the scopeshots I've posted? The underlying sine wave should be clear to you in this scopeshot. Whether it is there or not depends on the pot setting.

At the very beginning of that video that Stefan linked above, you can see that he has the scope probe leads looped around the light fixture which is very close to the scope and the circuit under test. Is that a CFL in that fixture, I wonder....

what is the high voltage lines frequency in that area? 270Hz does not seem divisible by 50 evenly. I am not a high voltage Line man or engineer thus someone with knowledge in this area would be a help. Comments?
