3v OU Flashlight
« on: April 14, 2014, 08:55:28 PM »
Hello all,

This thread is for the 3v OU Flashlight projects.

Translation of PerpettummobileOUFlashLight_02.JPG
~~~~~~~~~~~~~~~~~~~~~
Ferrite pot core OB30 M1500. 3 coils 50 turns each using 0.35mm insulated magnetic wire. The induction is 3x716 uH. Standard 2 sections coil holder. One section is used by the bifiler coil (L1 & L2) and the other section is for the L3. Naturally, an air gap of 0.5mm is required (according to the theory).

In accordance with the AN920 document Figure 18 (http://onsemi.com), the induction should be 115uH. I have achieved the same result by using 20 turns of 0.35 wire. Thus 3x115uH (L1,L2,L3)

DC inverter converts 3 volts to about 4,5 volts. It have frenquency about 1-50 probarly kiloherc. kl561 like see in video have about 20 herc, because blinking LED. Primary have about 40 turns ticker wire. Secondary have about 500-1000 turns. So here is something like modulation, then mixed low frenquency and hight voltage with hight frenquency and low voltage.

Я проверяя частоту с осцилиографом уже второй транзистор коротнул и испортил С1815.

the blinking LEDs circuit has been confirmed a fake as well. The trick was simple.  One of the capacitors is, in fact, an EDLC device (Electric double-layer capacitor). Once you jump-start the circuit it will work for several minutes.
If C2 were a high-capacity EDLC device, would the circuit react like this to the pot P1 being turned counterclockwise and then clockwise back again as in this video ?

hi verpies,

Avalon didn't knew i reverse engineered directly from video.He didn't know i spotted 1000uf 10v and 470uf  on capacitor in video.

Without doing any verification or validation himself and simply said "double layer capacitor" value used to make it sound like a fake which is more easy to spell than to proof. ;D :D 8)


Last night i came across one of the site which have a online calculator for MC34063.Do check it out.

The circuit would react exactly like that.
I do know that here are some die-hard fans who would ignore the very obvious simply because it makes them look bad by association. However, those are the facts. Follow the link I provided and you can see for yourself.

I would be very happy to see a successful replication. There are none. Why is that? Do you really believe that among thousands and thousand of replications we wouldn't see one more successful attempt?

As usual, Ocham's Razor provides the answer. The simplest solution is the true one.
Try for yourself: what is it more likely: a/it is a genuine design and the rest of the audience are imbeciles, or
b/ It is a fake.

I think you get my drift.
Having said all that, nothing would give e more pleasure than to see a genuine replication.

Я на видео сказал - попробуйте сделать чтоб так работало, ждем ваше видео разоблачение с суперконденсатором.
В любом случае никого не буду переубеджать, не хотите не надо.

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.

In my version be 100 pF, not 510 like in schematic.

Here I get 513 picofards, 0.98 omh resistor, 90 uH inductance, corversion voltage from 3 V to 5 V. Maximum output curent 0.07 A. Frenquency 43 kiloherc.


And in lats picture some impruvement... В последней картинке автору предложение, как немножко или, может, не немножко, усилить мощность.

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.

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.

Why?
What would turning the pot counterclockwise and back accomplish?
