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.


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