Is joule thief circuit gets overunity?

Oscilloscope analysis for Board 33 target for overunityresearch.com
COP=-1.78  Negative sign came from Input.
It looks like for the first test, all three boards 33, 38, 39 showed OU without the capacitor.

Second test - use Atten oscilloscope Model ADS1062CAL instead of ADS1062CA.
Board 33 was used.  The COP changed to -2.56.  This shows that with the same board and different connections, the COP result can be significantly different.  In our case, we are happy with any Average Output Power > Average Input Power results.

I have only looked briefly at the latest info here but I'd like to bring up a test I did some time back and am replicating this moment to check my memory of it.  It involves a 1 farad capacitor and a 5 mm bright LED.   That's it - no other parts.   I charge the cap up to about 4 volts by briefly touching it several times for just a couple seconds each across a small 9 volt battery.  I then hook up the LED.  It shines bright for a few minutes and slowly starts to dim down.  I'm retesting now to see how long it stays lit but in a past test some years ago I recall it was still lit after 5 or 6 hours. 
In the Joule thief above a 10 Farad cap is being used versus my 1 Farad cap.  I'm not saying there is nothing of interest with the JT but my setup has had the LED running steadily for hours.   Also my 1 Farad capacitor is very close to the size of the wound 1" toroid used in many JT's.   Just some food for thought.

Still glowing although dim - after 6.5 hours.  I would have let it run more but needed sleep....    I think I'll try running the JT circuit off this cap to see how the results compare.

I am now running the JT circuit shown here off of my 1 Farad cap.   I started the Cap at about the same voltage as the previous test which used only the LED.  I am using 1K Ohm TruOhm resistors (high precision),  a 2N2222a, a bifilar toroid that has always done better in JT's than any other I have.  It's a 4" diameter fairly high perm ferrite toroid.  This JT setup started out dimmer than my test with just the Cap and LED.  After 15 minutes it was about as dim as my Cap-LED only combo was at 5 hours.   It has now been running about 35 minutes and I can barely detect any light at all.  It is far dimmer now than my  Cap-LED only combo was at 6.5 hours. 
   So to bring it back to life I have eliminated the 1K Ohm resistor between the Negative and the emitter on the transistor.  I'll see how much longer it lasts now but I don't expect it to go nearly as long as the Cap-LED only combo.  Well in the amount of time it took me to type the last two sentences here it has gone from medium bright to almost totally gone.   Just checked again and I can't see any light at all now.   I just disconnected and reconnected the Cap and I see no difference at all so it probably only lasted another minute or two.  Total runtime roughly 40 minutes at most.   I won't say my test was scientific but I certainly didn't see any OU.  Not even close to as good of efficiency as just an LED hooked to this same capacitor.

Please wait for the 3 forums to receive and test the tuned oscilloscope-test-ready boards.  Let them verify and confirm OU before you go the next step.  Without tuning, few Joule Thief Circuits show OU characteristics....  If you are willing to post your test equipment, procedure and results openly on this forum, I shall consider sending a tuned oscilloscope-test-ready board to you for thorough testing in the next batch.  The waiting time for this batch is 6 weeks.

looks very promising bro... resonance circuit - i might think like a conventional electronic design engineer.

if your saying about tuning the resonance circuit... are you doing any simulation on it.
