3v OU Flashlight

My search engine wont connect with that site it says it's trying to down load malware.

you can get toroids wit hysteresis they are the old type used in computer memory
they would be used in switching memory circuit and i read they can stor magnetic field.

yeah something is wrong with this site.
go back to my previous post and see my attachement.

I think this may be related. I plan to check it , waiting for some MKP capacitors to test.

That circuit is not related to LED flashlight. The original circuit was creating resonance in ferrite and also had static potential taking back to circuit for creating second power input.

For example, akula was explaining how to create ferro-resonance and taking static potential from copper plates on both sides of the coil:

And the demo circuit with step-down from potential taken from plates on core mixed with piezoelectric material:

From the closest near-unity replications you can also check on lasersaber circuit - https://www.youtube.com/watch?v=1RXolkA08uk

forest,
Interesting yes and not related to the flash-circuit. In welseys thread there was a similar circuit however there was a periodic short-circuit at peak power of the left coil.I am really curious of what you will come up with, good luck


@T-1000 :
all those endless russian videos do not help here simply because we do not speak your language. It was already much work to go through all the postings of the realstannik-forum via google translator.From what I read today the users are frustrated and beleive that this is no valuable approach.
Besides there is a much more simple LED Flasher based on negistor-circuit.
Edit: we should be correct when we talk about phyhical phaenomena that is:

Akula certainly is not experiencing ferroresonance but rather creating ultrasound by magnetostriction and this can happen at diffreren frequencies.Otherwise he would have killed his small transformer in a few seconds...somthing what happenes mainly in power-networks.
Ferroresonance is clearly defined:

Key points: "approaching the knee of the BH-Curve and the remaining much lower inductance in combination with capacitance (series resonance) -> current spike
