Joule Thief 101

Brad:

MH,your an idiot,and im done with you and your bullshit.
You bring nothing to this forum,other than negativity,and dismiss everything anyone says about resonance.

Well I am not BSing and you are BSing yourself.  You talk a lot of BS about resonance when you talk about electrical circuits and that gets you nowhere.  If you talked straight talk about electrical resonance then I would agree with you.

Tell us all again how there is no resonant features used in ICEs to make them more efficient and powerful -->proved you wrong there without a shadow of a doubt.

I am going to repeat to you again one more time and let's see if it sinks in this time:  We are talking about resonance like a wine glass resonates, that's a true example of the scientific and engineering definition of resonance.  We are not talking "motor shop talk" about "resonance."

Now is that going to sink into your head or are you going to bury your head in the sand?

Face it MH,you dont belong here with your negative and incorrect attitude.
Your way out of your league when it comes to resonant systems in an ICE,and i have shown you just how far behind the 8 ball you are.

Don't sulk in the corner.  We are not talking about internal combustion engines, and I never claimed to be an expert on internal combustion engines.  So your comment above is one of the sleaziest and most pathetic bait and switches you have tried to pull off on me.

Out of the two of us,i was the only one to correctly explain as to how the JT circuit was working at low voltages,while you were to scared to even have a go at explaining it.

Check your pants.

But what is it that happens that there ends up being a 'sweet spot'? Why not as good above or below that spot?

Presumably the engine operates better, the timing is better, the gasses move in and out of the cylinders more efficiently - but that is NOT RESONANCE like a wine glass resonates by a long shot.

Well what about Brads JT that has this sweet spot? My JT didnt have a sweet spot yet.  What do you think is happening in Brads circuit that would cause the 'sweet spot' where it runs with less light output above and below the 'sweet' spot? With my JT it is either up is up or down is down.  What is it other than he hit some resonant freq of the transformer? How do you explain that?

MH
You clearly stated that there is no resonant activities in an ICE,and i proved you wrong.
Man up,and except the fact that you were wrong,as that is a fact.

Now is that going to sink into your head or are you going to bury your head in the sand?

It is you that has there head buried in the sand,with your one track mind.-,and that is quite evident in this thread.

Oh please.
Why do you continue to bullshit--or try to bullshit your way out of your own screwup's?.

Post 514 Quote : No, an ICE doesn't resonate in any way, shape or form whatsoever.

A bold statement from some one now claiming to be no ex-spurt on ICEs--also incorrect,and proven to be so on multiple occasions.

Check your pants.

Check your memory,as it seems to be fading fast.
If so,just go back,and re read what you have stated beforehand.

Some facts you need to learn before you go making a bigger fool of your self
1- MH dose NOT get to decide what a JT circuit is.
2- MH dose not determine how many different types of resonance there are.
These are facts MH--so suck em up princes.

All that I can do is take his verbal description and look at the waveforms.  How can you possibly say that he "hit some resonant frequency of the transformer?"  "What is it other than" is the big clue.  You are making an assumption because you think that "has to fit."  My instincts are telling me that a serious bench analysis will not uncover any resonance.  Finally, if the transformer was resonating then we would see a sine wave signature and there is no sine wave signature in sight.

And I will repeat again, why should a "resonant transformer" give you better results when by definition you have high currents and increased i-squared-R losses at resonance?  A serious bench analysis would uncover the reason or reasons for the sweet spot but it is highly unlikely you will uncover any true resonance.  Like I stated before, it is a circuit in oscillation at an operating frequency, not at a resonant frequency.
