Is joule thief circuit gets overunity?

"Suck-in" energy might be more appropriate than "Lead-out".  Mr. Lau's graph would be much more exciting if its slope reversed, or even flattened totally out.

With the success of the experiments on Board 121 and 122, Mr. T S Lau continues on.

This time, he is comparing Board 127 and 128 with rechargeable Batteries.  Board 127 is the standard Joule Thief with a capacitor.  Board 128 has the Twin Timer.  It is a repeat experiment.  There is still the possibility that the Timer may induce energy.

I prefer "brought-in".  One of the things Mr. Lau will focus on next time is the small peak for Board 121.  He happened to notice a votage rise at that time and focused on taking readings at 2 minute rather than 12 hour intervals.  There could have been many more such peaks.  I shall try to pick out more with the Atten monitoring the voltage change at around 0.4V. 

Why should there be such Voltage Peaks???  Energy sucked-in???

@Itseung888:

As far as I understand, you have sent out at least 30 of your devices to various people.

Did you get any useful feed back?

Greetings, Conrad

I late last year attended with a friend a demonstration of some of the "boards" in California. Itseung888 was online via Skype. None showed any signs of over unity and when the batteries were removed the caps ran down. I was going to order one to test in our lab for the purposes of showing the results on some high end equipment with people who know what they are doing when it comes to measurement. What followed was even more astonishing. We were sent an email where it stated I and my friend were so impressed we were to fly to Asia to form a business relationship. I let my friend deal with that (I am not using his name). I did not bother to proceed with any testing after that.
This may not be of any use to anyone but I felt since you were asking.
PS I love these little circuits and all the fun experimenters have with them, I am even testing a few in our water battery technologies. Bottom line...no over-unity.
Kind Regards
Mark

Lawrence..... I am completely flabbergasted. You have not told us, until now ..... that your Timer is powered from the AC MAINS. AC 110/220 V, right on the label. Is that right? You have AC mains power coming in to your timer box, which contains who knows what kind of transformer, switching power supply, solid state relay, oscillator inside it.... powered by the AC mains ? Right next to your JT which as I have shown is perfectly capable of picking up energy wirelessly

I submit to you here and now that ALL your data taken using this timer is suspect, as is ALL your data taken with those God-forsaken ATTEN sillyscopes.

Further, the little bump on Mr. Lau's graph is called "noise" or "sampling error". If you had data at higher temporal resolution you would no doubt see more of these little bumps. And if you had, say, twenty Atten scopes and twenty JTs to monitor all at the same time, you'd see bumps all over the place. And then when you averaged them all together you would see "average" behaviour that was smooth. In short, the bumps are likely insignificant pimples that mean nothing in reality. Chase them down by all means.... but not using an Atten oscilloscope or a mains-powered "timer" sitting next to your device-under-test.
