3v OU Flashlight

[eszdman]

Вадим, тебе предложение, как усилить мощность. Диоды шотки только. Мотается дополнительная обмотка, поверх или под низом, не важно, из такого количества витков, как примерно одна из обмоток. И ещё 1 мкф конденсатор добавил, лучше 100 вольт, но он не принципиален, он может повысить мощность.

Если так подключать все импульсы испугаются

Also due 3 topics on 2 different forums I am not sure if here it is best to drop in more information about it but I will try.
Delamorto/Akula LEDs flashlights circuits are following that patent application too.
Probably everyone remember self runner circuit - https://www.youtube.com/watch?v=Du8_moSa7KY
It is real manifestation of what was in patent application.
Here is its top circuit diagram of circuit in that video:

I don't understand the meaning of the the "coil 1.4". I can't find any clues in the melnitchenko docs. Where is the additional energy come from? I think the coil shorting isn't the key piece of the OU flashlight.

In this new video Akula analyzes Vadik's 3V Flashlight, which is the subject of this thread.
Akula uses his signal generator instead of the  к561лн2 CMOS Hex inverter to generate the low frequency pulsing of the outer winding (19.3Hz)
The yellow channel of his oscilloscope shows the signal at pin 1 of the MC34063 and the blue channel shows the signal at the collector of Q1 (non-decaying 290kHz oscillations).

He explains the cause of Vadik's inability to light 2 LEDs with his circuit (he blames it on the power consumption of the CMOS chip and on parallel LED connection).

hi verpies,

Base on my previous experiment on HCF4069,i merely grounded all the 3 input of unused inverter else the power consumption may increase if gates within inverter getting stray signal.
The current on 3.4volt battery is mere 450uA with high efficient bright green Led which is connected to 27k ohms in series which i have attached the video previously few days back.
I know 27k ohms may sound a little too high but it works for me.

I manage to find a ferrite pot core of mere 3cm diameter locally which is small.This may not be recommended for this project.
Using 22AWG wire i can only wind around 17 turns on each layer and insulated each layer with trimmed transparent tape.Hence i created 3 layers of 17turns and 4th layer of around 10 turns.
17x3=51+10=61 turns.Copper shield with  gap is used on both sides.

The other primary turns is around 17 turns ,1 layer.

Following the video 4 i also used hard paper and cut into a small circle and merely placed on the center of core to form a gap between the ferrite half and to ensure the 2 ferrite half never touches.
I then seal off with tape around the 2 half of core.

Using the common 2SC1815  merely connected to signal generator via 1k resistor with 3.4v battery and used 61 turns winding only.

Between positive and transistor collector i have also connected to self made bridge rectifier using 4 x   <30ns TO-220 600v diodes.

Objective to find out what kind of dc voltage i would get from Bemf on 3.4volts battery.

Final result i have obtained maximum dc voltage of around 120volts using 9KHZ on 10% duty cycle sq wave.

The most interesting part is the current draw on 3.4volt battery is mere 2mA.I wonder if the 2 copper shield have anything to do with it.
I did not mention i have used 1000uf capacitor on emitter and (+) on test circuit.

I have also connected to a 5uf 275AC capacitor to the rectified output which increase voltage a little more.

I will need to find time tomorrow to try inserting signal to 17 turns just to see if i can obtain maximum voltage from 61 turns coil.

Warning: If my M.O. of this circuit is correct then you should not use acoustically dampening materials such as a vinyl or Teflon tape on the core.
The ideal insulating spacer separating the core is mica (because it does not dampen ultrasonic core vibrations).  Paper is worse than mica but not as bad as vinyl tape.
