TheGeneralHackr:
I came across a over unity design while messing around with a joule thief schematic. I measured the output and input amperage and to my astonishment there was 5 ma's more coming out of the output then input. Later I found out the meter was off by 5 ma's but that still makes this circuit 100% efficient. I have a few videos up on my channel  https://www.youtube.com/user/TheGeneralHackr

I could not replicate this device, I need a specific RF choke core for the transformer. Hopefully one of you can replicate it. I am releasing the schematic on here with a few other pictures.

hartiberlin:
Where do you connect the secondary battery ?

Please upload only 800x600 pixel images.
Many thanks.

Regards, Stefan.

TinselKoala:
Yes, indeed.

It would be nice to know:
-the coil turns and core material
-the place for the second battery in the circuit
-the value of the electrolytic capacitor ("Any"? Like a 10F supercap or a 100 nF tantalum would both work just as well?)
-the type of LED (different colors/types have different fwd voltages)

The battery voltage/time chart is interesting, but also raises some questions.
The no-load terminal voltage of a battery can be very deceiving as to the state-of-charge,
and voltmeters aren't very good at measuring the voltage output of a JT when the circuit
is operating, since they produce such spiky signals.

TheGeneralHackr:
Ok here are the specifications on the coil, led and capacitor I have used for the LCAP Circuit.

The capacitor I am currently using is a 16 volt 470 uf electrolitic cap but any electrolitic capacitor should work. I have tried values from 1 uf to around 21,000 uf (Disregard my message about the 80,000 uf tinselkoala I didnt get the exact value until now)

I dont have very much to say about the led other then it is a white 3mm 3 volt led. I bought it in a pack of cheap leds from electronic goldmine.

The coil in this circuit is the most important thing as of now I cannot replicate the circuit I need the exact coil. Here are the details about the coil, it is a rf choke from a old crt tv. The coil has around 20-25 turns of 22 gauge wire showing 0.8 ohms on my muiltimeter. The coil turns are the same on each side. Serial number shown on the side is 37-C5161116 0401 MC REV-B

Here is a updated version of the scematic including the secondary battery and a optional blocking diode between the collector and positive of the secondary battery. The diode I used was a low voltage drop blocking diode.

Hi,

Your coil seems to be a common mode choke used at the mains input of (mainly switch mode) power supplies.
At Digikey I did some search because they have a huge selection on such chokes.
See this link:

You can position your mouse over the pictures to get a blown-up picture of any of the coils shown,
if that can further help the identification for a similar coil.
Also you can reduce the DC resistance range in the DCR box above the list
(hold down 'Ctrl' while selecting values within the box). 
I chose DC resistance range between 0.5 Ohm to 0.95 Ohm. 
If you happen to have an L meter, it would help also to choose a similar coil,
because in the charts the inductance for such choke coils is also given.

Your circuit is a kind of blocking oscillator and these can be very efficient indeed.
Very careful measurements are needed to explore their real and true efficiency number.
