Very good, the audio was "interesting" too... hehe

There may be some problem loading some of those images -- so I put them all together into a short video with a voiceover narration.

@TK,

Great Job.  I believe you have examined the circuit diagram in detail.  The trick is to have common grounding for the two probes for the two oscilloscopes.  That is why A3 and A4 looked strange.

Your technique is much better than using the breadboard or simple soldering.  It can stand the shaking during transport.  Your workmanship is much superior to mine.  I had to spend an average of 3 days to do one board and half of the time, things went wrong due to bad connections or soldering.

If you have two Atten Oscilloscopes or equivalent, you can immediately do the oscilloscope analysis.  With the board as is, the chance of achieving overunity is not too high.  However, you can improve the odds easily by:

(1) Use a DC Power Supply as Source and watch the waveforms on the oscilloscopes.  I found that a lower value (less than 1V DC) can get to higher COP in many cases.

(2) Use the 2.3 10F capacitor (less than 2 USD in Shenzhen) in parallel with the battery or power supply and then disconnect the battery.  The LEDs should remain ON for more than 10 minutes and get dimmer slowly.  The frequency (best to use the Output Voltage frequency) will slowly shift.  At some point, you may find that the COP greater than 1.  This will give you a much higher chance of achieving COP greater than 1.

(3) Once you achieved COP greater than 1 with your set up at a certain frequency range, try to remain in that range with appropriate re-connection of the battery.  Do it manually first and later with circuits.

(4) That is the secret of "Tuning for Tseung Resonance".  Tuning is no longer a shot in the dark or luck.

(5) If you have difficulty in finding the capacitor, I shall be happy to mail you one FREE.  Your oscilloscope-test-ready board will be a great help to all free energy researchers.

Keep up the excellent work.  You will have overunity devices in your hands within days or weeks.

Re-mystifying the Joule Thief: JT basic testbed (circuit identical to LTseung's) with addition of 70 nF poly film cap, switchable across 1k base resistor, and using the modified Loopstick as the inductor. Load is 24 LEDs, (12 parallel) + (12 parallel) in series. Note that I get pretty good "dim" brightness in the array, even at 1 V and 0.6 milliamps (600 microAmps) input. That is 25 _microwatts_ per LED. Even at the "full" brightness level (with cap) the system only draws 9 or 10 mA, or well under half a milliWatt per LED.
And....the system has several distinct operating modes, but a battery that is too full saturates it and makes it stop working.

Resonance or magic?!?

Or just electronics......

@TK

Referring to your video, how long can the very bright mode with the capacitor connected be maintained?  That may already show overunity characteristics.  You may already have a "commerically valuable condition" that can be developed into a product.

As you have demonstrated, adding a capacitor totally changed the characteristics of a standard JT.  You did not even use a supercap!  LCR oscillation matching with the Pulsing frequency of the switching transistor got you into "resonance"? 

Please compare the Input Power and the Output Power at this bright condition.  The chance that it is overunity is very high.  You already have the circuit diagram to do a two oscilloscope analysis. 

Congratulations.

The Divine Wine is flowing out from TK......  Amen.

Erased by myself -

due to long waiting for approval of attachement ?

@Lawrence & @all

(I had to give up the long waiting to get the attached file approved,
so I put it on an external service instead)

I first found Lawrence work on the FLEET-device on the OUR-forum,
but it was blocked for other than internally admired members

So I first sent this mail a couple of weeks ago to the hotmail and
netvigator.com address of Lawrence, but it possibly didn't work.

Lawrence, did you receive this on your hotmail address?
