Joule Thief 101

[tinman]

Here are the two questions again:

How does a wine glass resonate, what is the mechanism?
How is the resonant frequency of a wine glass determined?

All of the whining and complaining and moaning and making up excuses is just you saying that you don't truly understand what resonance is because if you did you could answer both questions without batting an eyelash.

So right now you are unable to answer the questions, period.  I will answer them in four to eight weeks.  Now if you wanted to undertake to learn something on your own volition and came back and answered them correctly that would be great.

Well, I'm telling you that you are wrong.  You said you couldn't answer the question about the frequency without specifics, implying that if you were given the specifics you could.  Then after you are told to supply the specifics yourself, you go into a whole song and dance routine and whine about how it is too complicated and you can't supply the specifics.  You were bluffing the whole time.  It's a farce.

It's a farce because you have been arguing about resonance in a Joule Thief and you can't even explain the mechanism of resonance for a wine glass.  It's a farce because you put up some scope shots of your Joule Thief and said, "This is a Joule Thief in resonance," when that was obviously not the case.

In a month or two when I answer the questions don't you dare say, "Oh, of course, that was so obvious that I didn't bother stating it."  Based on your current behaviour, I wouldn't put that past you.  Don't you dare do that Brad.  If the obvious is so obvious then state it now.

Clearly many people don't understand what resonance is nor can they explain it.  It's just a vague concept and all they can do is parrot out the definition of resonance but they can't apply it to a real-wold example and show that they understand what they are talking about.  The same thing applies to a "resonant Joule Thief."  For starters it's a switching device with an operating frequency, not a resonant frequency.  Nobody can define what a "resonant Joule Thief" actually is.  They can't explain the mechanism, they can't sketch out a timing diagram and show where the resonance is and show what the benefits are.  It's just like the foolishness around a "self-resonant coil" because of that Tesla patent.

So for years there has been chatter about a "resonant Joule Thief" and from what I can see, there is nothing to show for it at all.  Relative to the standard definition of a Joule Thief, a "resonant Joule Thief" is an oxymoron.

I really hope Magluvin gets the time to work with Smoky2 and look for a "resonant Joule Thief" and documents it properly and sketches out a full timing diagram showing exactly where the resonance is and explaining the alleged mechanism for the resonance and showing the alleged benefits.  However, I am not holding my breath on this.

  Just say a particular frequency when the reactance of an inductor and a
  capacitor balance.
  End of story!
  Tinman science and MarkE science are worlds apart.
   When I'm flying I go by the book, as a fellow pilot I'll bet the
   Koala would agree.

THIS IS FOR MILE HIGH THIS IS WHAT YOU CALL A JOULE THIEF,

I GUESS TINMAN IS GOING TO DO THE DUDE THING AGAIN..
