Akula0083 30 Watt Self Running Generator.

Talking about LED flashlights, they can be very efficient when are in looped mode.
For example, lasersaber also was experimenting with them and he came up with one which draws micro-amps to light up LED - https://www.youtube.com/watch?v=K7D_9Ill2wM with circuit in http://laserhacker.com/?p=420
Also no one is going to make 15+ hours video showing how long they run after initial pulse but these circuits can find their use even if they do not run for ages...


Cheers!

@Itsu:
Also, I am using 600pF for C2; I experimented to get this value in order to get rid of the "double peaks" within each main pulsation of the chip. The peaks are caused by the resonant ringing of the primary coil. I think that little spike on your yellow trace is the start of a second cycle of this ringing in your circuit. You might try increasing the C2 value a little bit to see if that makes that little spike go away and gives you a waveform that looks more like that in Lari-Man's video.

I don't know about the diac... I'm using a UF4001 rectifier diode there. The 220 uF capacitor I'm using is only rated 16 volts, and as you can see at your Testpoint on the other side of this diode (the junction of the Anode side of the third LED and of the diode) , the voltage gets pretty high, or rather low (negative) and this diode keeps that negative trough out of the capacitor. On the capacitor side of the diode I see only a straight DC voltage that is well below the 16V rating of my capacitor.

Ok,  i added another 220pF to C2, but still a small second peak was visible.
After adding another 470pF its gone, so i now have about 1nF for C2.
The frequency increased to 77KHz.

You haven't even watched the videos but you have already made own "fantasy theory".
Funny approch.

BTW if you already have Tesla Transformer you don't need a Katcher to take of power with N.Yablokov assymetirc  capacitor.

Take it or leave it - you are on the own. 

I just love the way people try to tell me what to do and how to do it... when they haven't presented any work of their own that supports their contentions.... while I actually do show my work and my results clearly and (mostly) fully explained.

My theories are not fantasy, they are supported by my own experiments, demonstrations and hundreds of years of experimentation and research by real scientists.

Changing the diac for an 1n4148 diode does not change the signals.
Playing with the gap (piece of paper) introduces oscillations inbetween the pulses (yellow trace)

Hello everyone,

I have spotted the fake just minutes into watching the original video from Lari as from the link as posted by Tinsekoala.

I have even put a comment "hint" in comment just beneath Lari's own comment "Fake".

Sometimes you guys do make my laugh.But the fun stops here since it's Monday blues over here.

Hey i am doing this so that you guys won't waste a single seconds in this "Russian version of April fool joke" which strangely seems convincing to many.

No further comment to add.

There is a slight difference in the layout of his circuit board, compared to the template which I used to make my board. The routing of the + and - power input leads are slightly different, but electrically the same I think.  The result is that his + and - input wires are reversed and are like Itsu's, with + on the right side viewed from the top. Mine follows the template posted by Enjoykin, and so the + is on the left side when viewed from the top.

I'm afraid I don't see what else you might be seeing on the Lari Man circuit board. Please enlighten us!  (no pun intended...)
