3v OU Flashlight

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"    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.

Thank you!

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...
