Akula eternal lantern 4

[Dave45]

I cannot tell for how long Akula's devices managed to run. However, I ran my circuit for a week before manually switching it off.
I have not, however, tried it with a few LEDs attached which may result in a short run time, primarily because I am not interested in creating yet another lantern. I will show a high output device when it is ready.

Anyway, the effect is real and can be harnessed. Akula is not entirely correct in his explanations regarding the nature of the phenomenon, but it exists and can be applied easily.

Have a look:

Was that with the FG's running the gate.

Very impressive. Can you please share more details of your setup, like the ferrite core, number of turns and connection diagram. Best regards

Actually, no. I used a simple MAX931-based circuit for that. I did not use it in the video as it would create more questions. Gens are way more visual.
I am also experimenting with TS3002 but have not used it in a self-runner yet.

Far more important was the choice of diods. I used FSF05A60 in my setup.

Hello!

I am trying to replicate LaserSabre device and it really works, but I have to tune it, since my version can power LED for cca 3 seconds only.
My setup is EI ferrite core with 2 coils of copper wire (100P and 80S turns), NPN transistor KF506 (very old, but I found just this at home), some kind of classic diode (actually works longer without it) and capacitor 10V 2200uF.
It seems as turn count is crucial (more is better?), of course ratio too.
I have tried some MOSFET transitor too, but it seems it is not as good at least with this one.

Its running from 2S lipo (8.4V) when fully charged. I dont know if it is enough

I seems get almost exatly osciliograme like akula. I use for generator TL494 with ajustable duty cycle and frenquency. So seems circuit is realitivi is extreamly simple. I use frenquency about 20-50 herc. But I try with other number of turns of primary and secondary make selfrunning and not get selfrunning. And I use fet transistor (IRF610 with two small bipolar transistors for fast open and close), not bipolar like Akula. I also use core from flayback.  Good lock for all in experiments!
