Is joule thief circuit gets overunity?

[TinselKoala]

@TK,

We can make this very simple.  Tell me what kind of DSOs you have and how many.  I shall get one of the oscilloscope-test-ready boards for you.  Before I ship it, I shall have my team double and triple check it just like the ones for the top universities.  The data will be posted on the Internet.

All you need to do is to hook up the connections as indicated and show the analysis from your DSO.  I can justify it as a rehearsal before the sending of such boards to the Universities.

In resonance experiments, one different component may give you very different results.  Let us not waste time and energy.

You are not being cooperative. You are not answering my questions nor are you explaining the things I want you to explain. Let us not waste time and energy talking about resonance when you have none: your scope traces do not reflect a resonant condition in your transformer. If you had resonance in your transformer your output would look very different. Did you not watch my video where I resonate the JT coil? As it is... your output looks exactly like mine.

But OK, I will play your game. I don't want you to send me anything, though. I just want you to do some testing in parallel with me, right here and now. I'll test my board and you test yours and we will compare values and scopeshots and all of that. OK?  The first thing I want you to do is to reproduce that voltage measurement graph and tell me exactly the things I have asked for. Surely this is easier and faster than you trying to send me something from your location, and it will be more instructive as well.

For your information, I have available a Tektronix DPO4034 4-channel oscilloscope, with live math capability. Unfortunately only the one. I also have available a Clarke-Hess 2330 power analyzer and some very sensitive high impedance voltmeters. These instruments do not belong to me and I have to travel some little distance to use them, so I do not do so casually. I do not yet feel the need for a DSO in analyzing your system, though, and your reliance on one is actually quite depressing, since it's pretty clear that you are just learning how to use a scope in the first place and you still are not clear on the relationship between power and energy.

I believe that we should at least have oscilloscope-test-ready boards with similar characteristics before our discussions can be fruitful.

My measurements are to be done in 20 minute run intervals.  Your board died in about 2 minutes.  Please let me send you a properly tuned FLEET.  The top Universities wanted and demanded that.  I believe that it is the right thing to do.  Asking me to accept the result of your 2-minute board as authorative is too much!!!!!

Asking me to accept the result of your 2-minute board as authorative is too much!!!!!

And it is something that I have not done.

I have asked you to explain to me the exact conditions under which your last scopeshot was obtained. I have also asked you to do some simple experiments in parallel with me, so that we both may understand what is going on. I have never stated that my work is "authorative" (sic), but rather that yours is NOT. There is a big difference there. Unless I can duplicate your conditions I cannot proceed, clearly. And I DO NOT WANT you to send me a board at all, because there will be many accusations resulting from that action should I accept. What I will consent to is for ME to send a board of my circuit to whomever is testing YOUR board, so that they can be tested side-by-side. The fact that I cannot afford to buy copies of your supercapacitor clearly works against me here, but I don't care.... whoever tests can no doubt provide a suitable capacitor to install in my unit.

What is the voltage on your capacitor, measured with a simple DMM, at the start of the 20 minute period and at the end of the 20 minute period? Is this such a hard question for you to answer? Why?

ETA: Do you know the "tolerance" range of your supercaps? The ones I find that look similar have a tolerance of
-20%〜+80%
of rated capacitance.
This means to me that you don't even know the capacitance of your capacitors, unless you have measured each and every one of them with some kind of accurate and precise techniques. Have you done this?

ETA2: What are the specifics of your toroid windings? Those pictures do not appear to show what you said in your last description that I can find.

More clarification.

The oscilloscope-test-ready board has the following features:
(1) Allow the tester to put in any load.
(2) Allow the tester to use battery, DC Power Supply, Capacitor alone.
(3) Or capacitor with either battery or DC Power Supply.
See the updated diagram.

Unless I can duplicate your conditions I cannot proceed, clearly.

you seem to have great difficulty 'duplicating' a lot of these JT circuits... you cannot 'duplicate' gadget's, you cannot 'duplicate' lasersaber's, etc., etc.

anyone else notice this pattern?
