3v OU Flashlight

Hi All,
I made a compilation movie of the last 2 videos from Akula,
cause he seemed to have deleted his youtube channel....or I still
can not find it anymore.
Fortunately I did save these movies and have also put in the circuit diagrams,
at least for the higher power versions...cause the newest was not yet posted,
when I made this video...

Enjoy !


Regards, Stefan.

Neither Russian nor English is Wesley's native language.
There are so many Russian native speakers on this forum, yet I don't see them translating videos.  If they did, he would not have to.

looks like 5.4mH and 1.25mH to me..... (Edit: no I'm wrong, 54 and 22)

and my crude drawing.... though it apparently doesn't apply for the flyback ferrites





someone should do a better job   the bottom and top foil windings should be the same way... and the first extends backwards from the direction the secondary is wound... then at the end, it extends backwards from the direction of the winding


(Edit: rotation is kinda backwards, resembles video more if flipped upside down)

drawing is a joke ...

Then Akula's core must have a hell of a permeability.

Yep. I don't think it's possible to get that high inductance with what he showed (number of turns and core). Of course that's not the only impossibility around this circuit and claims....
