MVI-2352.AVI.exe   - what are you trying to pull?

Hi verpies,

In this link http://www.speedyshare.com/4teBf/MVI-2352.AVI   you can download the video file by clicking on the MVI-2352.AVI shown in middle of the top line,  next to the word:  DOWNLOAD   

If you go down to the very bottom of the link , there is also a DOWNLOAD icon in green which would include an exe file enforced by speedshare.com  as written in the bottom:  Download this file for free using Tiny DM manager (exe app)

Намотал на феритового трансформатора сердечник. Тоже нет самозапита. Подозреваю, что либо мой транзистор не достаточно хорош, хоть и называется как надо ,но этих версий, видимо, полно с одинаковым названием, либо витков у той катушки, которая имеет больше витков слишком мало, у меня 350. А другая, которая, к инвертору, имеет 27 витков где-то. Вот эти две причины основные, думаю, почему у меня не работает. Я убрал и второй светодиод, чтоб не потреблял он и у первого, зелёного, поставил вместо 1 килоома 2,2 килоом резистор, чтоб тоже он меньше потреблял, но самозапитки, как говорил, нету. Либо ещё что у меня другая микросхема задающего генератора, которая имеет не 7 ножек, а 8 ножек на плечо. Она может больше потребляет и может немножко по другому работает.

трансформатор такой?
a transformer?


При настройке я не пользовался осциллографом, на моем блоке питания есть амперметр, я подгонял все сопротивления до 0 потребления. Потом все само-запиталось.


When configuring I did not use an oscilloscope on my power supply has an ammeter, I drove all the resistance to 0 consumption. Then all self-energized.

Не такой, такие не знаю где продают. Но, думаю, тут смысл не в трансформаторе.

Тут вроде бы продают http://evita.lt/det-2977-product.html эти сердечники, может куплю.

I replicated the circuit but don't have right core.

Don't you think that circuit's behavior after pot turning is more significant than the visual evidence of a capacitor type and value?
After all, a dishonest person can gut a regular electrolytic capacitor and insert a supercap inside ...or a battery.

hi verpies,

Both did play a part.
I do own capacitors in the farad range but it does have a catch the recommended voltage is 2.5volt maximum is 2.7volts.
Take a look at the 470uf 16volts capacitor size against a high farad value capacitor if connected to the pin 6 of MC34063.


My dear friend the video which i am interested in and attempted to reverse engineer was only uploaded to youtube on 8th April.
How could any fool blatantly says there is already replication attempt already made which is likely based on other unverified circuit diagram which i am not interested in at all.
 "Before the video was even uploaded or existed" :D   Do think about it.


It's just a simple distraction for us which i don't fall for too easily.

If i suspect any device is a fake or really hard to replicate with no details provided .I will just ignore and don't waste time&effort even talking about it.


MC34063 and ferrite pot have been shipped out which i likely will received this item around 3week time(max).Best case 2 weeks.


--------------------------------
The creator of the circuit did reveal one hint once current/amperage from power supply(3v supply) to circuit dropped to 0.Then the circuit is self-running.It's simple for me to understand.

Else i was lost on how to find out if circuit goes to self -running besides disconnecting from power supply a couple of times after tuning.

"Answer tune and monitor current drawn at the same time"

I said in the video - so try to make that work, waiting for your video exposure from the supercapacitor.
In any case, no one will convince not want not.
I was only referring to the Russian site which implied that the design was a fake. However, if you have managed to make it work it would be a great help to anyone who's trying to replicate if you were to give that more details about the design.

As a matter of interest I will assemble the circuit in a few days when I have a bit more time. Luckily I have all of the right components.
The results will be posted here. Stand by...

I try with 330 pikofarads and with 660 picofarads, not get selfrunning. After 1-2 seconds light emiting diode goes dim, then I disconect from 3 V source.

Do measure current consumption to circuit as you tune which should be 0 or maybe appear negative value once circuit is running.

How about the counter poise(large square copper track connected to (-) ) beneath the pot core(lower half it looks like copper screw thread hole and solder to sq copper track) which many will overlook.

Does this play a part.I hope you ask...

So, how I see, conected to inverter have little ticker wire and 30-40 turns, it is on top. Conected to transistor colector and plus have 50-70 turns of little tinner wire and it is inside.

I also see copper tape under and over first winding, how is it connected, to ground?

Look Mr Semenihin's  diagram (schema ньюфонарик3.JPG ), it is one primary 10-12 turns and no copper foil.
The secondary has  3 coils, two copper foils and between them are 15-18 turns.  A copper foil means one turn with a little gap.
Yes, Yes, thank you, Mr. Semenihin !!!
 Please, Which is the button for correct my Writing ?

A (big) step in the right direction. This might jump-start successful replications. Kudos to you!
