Possibly, but here is a 50 farad supercap that looks like a regular cap unless the video or photos are very clear.
I remember that in those videos I could read the capacity of one of them in µF.
The other one I don't remember but magpwr reverse-engineered these videos in details and is more authoritative about them.

Yes, I think I saw that on one of those caps in video 3...I could not make out any writing on the other one.  Just a possibility to consider.

my discussion about this with people like you: http://www.overunityresearch.com/index.php?topic=1195.200  now I don't have registration there.
Calm down, atomic boy. I am sure no one wants to argue with you.
Just asking you to stick to the topic, leaving your exciting opinions and brilliant ideas on various matters to yourself.

Ok, another replication attempt with similar results as the ones before on this thread.

Using the TKLABS V1.4 diagram (thanks TK), with some component modifications for:

the transistor, its an IRFS630a MOSFET
The D1 diode is an MUR120
The inverter is a HEF4069UBP
The transformer is a E-core for the time being with low inductance, but with the copper tape both inside and outside.
 
the rest is as close as i could get it with the components available.

supply voltage and potmeter adjustments is very critical as mentioned before.

First run trail today, see screenshot and video.

Screenshot shows:

Purple trace (3) drain voltage
green trace (4)  gate signal
yellow trace (1) top of D1 diode (MUR120)
blue trace (2)   pin13

All with reference to ground.

You guys do know a PNP != FET ... the current doesn't go through the gate, and you'll likely need a pulldown to relieve the gate voltage...
a transistor the current always flows from the gate ... so it is a self pulldown...


so this inverter chip; is it meant for a mosfet or a transistor?


Edited: nevermind; I know the point isn't how it should conventionally work... maybe the specs are confused because it's an exploit of a flawed thing
so ya; ignore that

Looks nice Itsu... you are off to a good start I think. You can already see one thing: your mosfet isn't really switching at all, the Drain is staying at Battery voltage, yet you have oscillation bursts and the beginnings of a sinus signal. Do you have the larger inductance on the 34063 side? If not.... try it. Also try sticking an NPN transistor in there instead of the mosfet. B=G, C=D, E=S.

The schematic in that nice format is, I think, originally verpies's work, and it has gone through some changes, as you see. My last version is still working strong, drawing about 10 mA, making the approved waveforms, humming the ferrite, but the LEDs still go out when I pull the power.

Did everyone see the spacer in the center of the pot core at time 1:20?

has done some increadible work based on the same look pot core, check his video:

hi dllabarre,

I was thinking if this dielectric was a just piece paper cut into circle" or a circular piezo element."I know i can't cut hard paper into a perfect small circle such as these unless i have the right tool"

Maybe "piezo produce electricity or electrical spikes" from the "vibration" between the 2 half of the ferrite pot core based on original circuit diagram."I know this is a long shot" :D

In science we got to look at things from various angle which produce interesting answers from each and every individuals.

TKola and others you use 5,4 and 2,7 milihenries, but here can be 54 and 27 milihenries. I calculate that about 130-190 turns have 54 milihenries coil of this video https://www.youtube.com/watch?v=AGjlXAHpMKI And he core can be big and have hight prmability.

hi Menofather,

Since you are able to understand Akula words better than us why not you try to replicate the device and then show us where we had done wrong.
I will be happy to listen to you after your successful replication."I am still learning"
