Is joule thief circuit gets overunity?

How about putting a Schottky diode in series with the battery, and treating that battery-diode combo as a black-box "battery" source? Clearly, the diode will prevent any "reverse current" from reaching the battery. However, I think you will likely still see the same current waveforms as before,  including the zero-crossings that have been observed.
I have not tried this experiment myself, and since I don't see any zero-crossing to begin with it would be kind of useless for me to try it. But anyone who has a board that does make these zerocrossing current waveforms should probably try it, to see if the diode prevents the observed zero-crossings or not.

@Void,

Here are the results from Board 118 which will be sent to you for verification after all tests are done.  The Input Voltage from the DC Power Supply was again adjusted so that the LED was just ON.  CH2 (current) showed crossing 0 ref line with much "noise".  The "noise" was stretched out by varying the time scale. 

The result was a pulsed waveform similar to Board 119.  However, in this case, there was some wavy on the 0 ref line.  The actual waveform on the noise was somewhat different.

I shall let you do the "correct calibration" etc.   Do not rely on my Atten and my skill to provide conclusive results.   I may not be doing all the right set up and I am waiting for the 4-CH Tektronics and the "experts" to help me to the verification in a few weeks time.

I've asked you several times before: You have distributed many boards, maybe over a hundred. Where are the reports from the testers to whom you have sent these boards? We have only .99's report... his _negative_ report that indicates that your measurements of that board were faulty. Where are the reports from all the other testers? Have you gotten any responses at all, negative or positive?

@TK,

We are dealing with the Chinese mentality in Hong Kong and China.  Mr. Zhou was willing to show his picture but would not post on overunity.com.  Prof. Julia Tree in USA was willing to let me quote his to-be-confirmed results using the Student Laboratory oscilloscopes.  In his words: "The preliminary oscilloscope results indicated Output greater than Input but more research is required.  I am giving some of your boards to others for testing."

A factory owner said: "Why should I post the results of my engineers free to the World?  If it does not work, why waste time posting?  If it works, it will be top-secret until the product is on the Market.  I am not interested in non-profit activities."

A fellow researcher said:"What is the point of my posting?  Just look at the jeers you received.  If you are right, I do not get any credit.  In any case, your work has generated enough interest for people to pump extra resources.  I am looking forward to accessing the 4-CH Tektronics also. "

A retired electrical Engineer said: "I heard your presentation at least three times.  You are violating the Law of Conservation of Energy.  No oscillating circuit can generate energy from nothing."

A retired electronics Professor said: "I got the boards.  There is much more vigorous research required to claim overunity.  You are one of the dozens in Hong Kong showing similar boards.  Good luck."

When one sows seeds – what does the Bible say???

Noise analysis on Board 80.

I now use the pdf file so as not to occupy too much screen space.  Note slide 2, 3 and 4 in particular.  They showed probes shorted, no Input Voltage and just enough Input Voltage to light the LED.

What is the source of the Noise?  Noise is present even when there is NO Input Power?

Shall put equipment to different parts of the house.  Use microwave as Faraday cage?

Lawrence, it is entirely possible that your DC power supply is contributing to the noise in your signal.

I would like to see a scope trace of the power supply's output into a plain resistive load. If you set your power supply to 1.5 volts and use a 150 ohm and a 1 ohm resistor in series as the load, you will have I = V/R = 1.5/151 = just under 10 mA of current. You can then use the scope to look at the current in the 1 ohm resistor just as you have been doing with the JT boards.  Use wires that are as short as possible and solder the resistors together and to the wires to the power supply. Any noise that you see in the resulting scope trace will be coming from the power supply and/or the oscilloscope itself. It should take you about ten minutes to do this test, including waiting for the soldering iron to warm up.

By varying the value of the voltage setting or the larger resistor you can look at the noise level at several current output levels.

This is a "control" experiment, something that is in general lacking in the work of many free energy researchers. Doing experiments or demonstrations that illustrate your phenomenon of interest is all well and good; but designing the proper _control_ experiments to rule out hypotheses is a real art and is the key to the application of the scientific method itself.
