Akula0083 30 Watt Self Running Generator.

[Mike1902_40]

Hi @ all my name is Mike and i'm from austria. I didn't found the introduce thread.
I build some Joule Thiefs and a Laser Sabers SJR Looper. I like alternative energy 

I would like to build this schematic, that Enjoykin posted.

Best regards,
Mike

Golly... it's so easy to suspect _me_ of tuning to an external power source! Why don't you suspect Lari-Man, or Akula, or Ruslan, of doing the same thing? Since all of their circuits _do_ work as receivers of external power, and Ruslan even works for a commercial FM radio station !!

I changed C2 to 600 pF in order to get rid of the "double (even triple) peak" within the main pulses, lowering the resonant frequency of the primary tank, so now my scopeshot waveforms look almost exactly like Lari-Man's. I left C1 at 33 pF, and also changed the cheapo blue LEDs into even cheaper white ones. (The blue ones were so cheap they kept failing on me.) Here's a couple of photos of the board running on just over 5 V from a dead 9V battery, and the resulting scope trace.

I've also shot a video, which is being processed now and will be uploaded in a few minutes.

(edited to correct capacitor numbers... sorry about that...)

I have suspected that this was what Akula had been doing from the beginning.  I am not familiar with the others you mentioned.  Actually, I based this upon your thoughts (long ago) about the freqs being in the range of radio stations. Its either that or Akula is a genius.

So, I suppose this means I do not win a prize then?  Not even a cheezeburger?

I look forward to watching your video.

According to the video the briefcase with stripes has a coil ...
Coincidence that the image is also on the same case ..

Lots of people dedicated to confuse.
