This has got to be the most complicated Joule Thief ever designed.

Ошибка всех получать автономную работу сразу, на 1 видео у меня не было ключа на возврат энергии, получать нужно импульсы с "фонарик видео 1", их настраивают напряжением питания. Вот когда вы их увидите на осциллографе 1-4 вывод 34063, тогда надо настраивать коммутатор, а до тех пор отключите коммутатор.


Error getting all autonomous work immediately on one video I did not have a key to the return of energy, you need to get pulses with "фонарик видео 1", set up their supply voltage. That's when you'll see them on the oscilloscope output 1-4 34063, then you must configure the switch, but until then disconnect switch.

hi everyone,

I am guessing semenihin-77 is telling us to look for the waveform as produced by MC36043 only without connecting the switching I/C:4069 which produce the switching signal to the transistor.

This might be related to the tuning steps.

Refer to the basic youtube video 1 http://www.youtube.com/watch?v=0_8OlH4kkKM

The only thing i can't tell at which point in circuit he obtained the MC34063 waveform.I am only suspecting it is at pin one(Before diode) and (-).

Not forgetting the special winding steps with copper shield for the ferrite pot core to be done beforehand.

But i think the easy approach is to observe "current consumption" to circuit at 3volts during tuning stage.
There is only 2 pots which needs to be tuned.

I am also curious on how high the spikes would be produced by switching transistor(Japanese transistor "C1815" Vce 50volts maximum) on 3volts.
The diode model number is unknown or is it a low drop fast "Schottky diode" around 40...50volts.

---------------
For circuit builder please take note  fast switching "Schottky diode" is commonly used in step up converter circuit.
Example: 1N5817,1N5818,1N5819
----------------------------------

Please do not use the diode 1N400x series at all.The "efficiency" even if used in normal step-up converter circuit would be lowered.
This is really a bad choice 2 ways higher voltage drop across 1N400X series and slower switching capability.

Yes,  you have it,  in his text:  "you'll see them on the oscilloscope output 1-4 34063,"   the numbers 1 and 4 means Pin 1 (output) and Pin 4 (-).

For the 1N400x  diode series,  the equivalent but fast switching series was also introduced, it is the UF400x series, also cheap and good.  Of course the diode types 'Schottky' you listed are also ok.

Here my version how can maybe possible buil generator on not liner indution http://eurosamodelki.ru/katalog-samodelok/alternativnaja-energetika/generator-energii-na-nelineinoi-induktivnosti
Better use mosfets, but then need put ressitors 5 kilooms on every mosfet betwen gate and source and not 1 kiloomh resistor to gate, but 10-20 omh. IR2153 here is standart driver with regulated frenuency, from it going two signal (one workin, other not working, then oher working, one not working), here no two frenquences, only one and this one need regulate then curent gose to zero, then divice selfrun. But here I see error, blue line must be removed, but then using mosfets circuit can not operate properly.

@MenofFather,
maybe with isolated mosfet driver for that mosfet it can work. Like in the chinese DS replication with the 6 HV Fets connected in series

hi Menofather,

I have spotted 1st replication attempt from Russia base on similar key component used:Ferrite pot core.
The circuit didn't work for him but i can't tell merely by looking to see what is wrong since i don't understand Russian.

I can't tell what did he miss eg:fast diode,Coil spec unknown,no tuning was even done in video.

http://www.youtube.com/watch?feature=player_embedded&v=wHPsqVGXrBg


This is being discussed in this Russian forum.
http://zaryad.com/forum/viewtopic.php?f=8&t=8534&sid=44665f28bfdfd77d63d99cdd0f90dcbe&start=20



----------------------
hi everyone,

Although i have not received the components yet to even start on this project.

I have made a very important finding and likely final discovery for MC34063 on how to reduce current consumption once the circuit is completed.

The capacitor value between pin 3 and pin 4 would need to be changed according to your ferrite core value.

You see the tuning the potentiometer for the MC34063 only set  the required boost voltage output,just for example 3volts in 5volts output.

But you see the inductor reading\value  on core between connected to pin1 and pin 7 plays a huge role.

Long story made short.By changing the capacitor value 510pf to a higher or lower value all depend on the inductor\ferrite pot value between pin 1 and pin 7 of MC34063.

Steps to take to increase MC34063 efficiency-
1)First try without the switching I/C:4069  (Remove ic from socket or remove resistor to transistor only if everything was soldered onto board without socket)

2)Adjust pot until you get for example 5volts  at 1000uf capacitor using 3volts supply.

3)Observe the current consumption to circuit using 3volt supply.

4)If the current drawn by MC34063 is insane high like 200mA or even 100mA with just output to white Led via resistor.
   Please alter capacitor value between pin 3 and pin 4 until current consumption is lowered until you find the most suitable capacitor to use for your DIY ferrite inductor/ferrite core.

You will likely notice the voltage across 1000uf capacitor is still at 5volts for example.But this time the overall circuit efficiency is greatly improved at lower current drawn.

-----------------------------------------
My justification-

The capacitor value 510pf is likely a incorrect value since base on my knowledge any windings you do on larger ferrite core then likely it would be in Mili Henry since turns is around 25..30..
Optional L/C meter can be used to verify this.

510pf would be more suited for inductor value around 220uH.


who knows the 510 might be a 510nf instead  :D :D :D

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 :)

There is no English translation yet.
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.
