3v OU Flashlight

[avalon]

I did not construct circuit yet.I merely inject 9khz signal to transistor C1815 on breadboard which is connected to my untested winding.
The objective was merely to find out the  bemf or ideal bemf i would be getting from the winding with the 2 copper shield(gapped).

You are on the right path as far as I am concerned. I, too, am going to do in-depth ferrite research.

My approach is slightly different, though.
I have a 2 ch arbitrary waveform generator which can generate any signal I want (up to 14 bit resolution) from DC to 40Mhz.
I am going to sweep frequency range using different coils and ferrites in order to see if the ferroresonance can, indeed, be harnessed.
So, it is not so much the bemf that I am researching but the individual resonance frequencies for different types of ferrites and coils.

I can easily program the signal generator to emulate 34063 signals on one channel and the oscillator/switch signal on another channel.
Moreover, I can independently time-shift these two signals to emulate any possible synchronization scenario imaginable.

I will post the results here if there is anything interesting found.

Here i draw schematic how can be possible make generator on notliner induction. IR 2153 need 15 volts minimum and I not shore or on it works how need, so I draw on NE555.
And atach image how wery fast close mosfet transistor, better use that metod.

hi MenoFather,

To be honest i don't dare to try on work on any circuit where there is no video presentation done.

I only work on circuits which have a higher probability of success or those that i am interesting in ,not necessary it will be a success 100% of the time.

I noticed for some strange reason the Russian forum is down today which also discuss on 3volt ou light.

The use of the PNP Darlington (eg TIP125 or similar) to turn off the mosfet is a great idea. The faster and more cleanly you can turn off the mosfet, the greater the spike/ringing you will get from the switched inductor. A fast diode and Darlington as shown in the drawing could help, if that is the desired product.

hi everyone,

I can't tell if this is the 1st successful replication attempt since i don't understand Russian.Base on observation he manage to get green light blinking but unsuccessful when attempting to light red Led for long.
Please jump to 48min of the video.I can't tell what is he talking about the transistor.Please assist...

The sound on flyback core sounds little like a untuned radio.

I wonder if the 2 wire (+) and (-) in the original video is acting like antenna pickup unknowingly."Just guessing"
