Joule Thief 101

[MileHigh]

Brad:

I am not going to address almost all of what you said because it has been covered before and there is no point.  Then there is the "willful ignoring" of my responses to go in tandem with your willful ignorance.  It's either that or you have some cognitive issues where sometimes you are told something and the information passes right through you like you weren't even there.

A couple of times in this thread you have tried to define resonance like this: (paraphrasing) "Resonance is when you hit something at its resonant frequency and it starts to resonate."  That is a total fail and you clearly have some ways to go up the learning curve.

There is the only one outstanding issue for now, the two questions about the resonating wine glass:

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

My advice to you would be for you and Smoky2 to study and try to figure out how to answer the questions.  That will help you with the "resonant Joule Thief" immensely.

You have my answers to your questions-one of which you have failed to include.
The original question was-! What! determines the resonant frequency of the wine glass-noy ! How! is the resonant frequency of a wine glass determined.
You need to learn the difference between the two MH-who has the cognitive issue ?

Face it-you have no answer to your own questions that are any different than that provided by others here on this thread-which are much the same as given by me.
You have also failed on a number of occasions now to understand existing resonant systems increasing the efficiency of various systems presented to you, and backed up with facts.

So far, the only one here that has failed the resonant test is you MH.
The fact that it is going to take you 4 to 8 weeks to gather up the information needed to answer your own questions, is testimony toward youe knowledge on the subject.

Your all questions-no answers--》all talk, no action.
You have proudly shown us this in this thread.

Brad.

At this point Brad that's just a bunch of useless trash talk that we have all seen before.  Open up some books and apply yourself and try to answer the questions if and when you can.  Sorry, but for this resonance discussion I had to call your bluff.

Mh
You have not called anyones bluff. In fact, the bluff is from you, and you were called out by others, along with myself.
You were wrong about there being no resonance going on in an ICE.
You missed vital information in regards to your determining the top speed of a car.
You have provided no answers to your own questions that would prove myself and others wrong in regards to your questions.

So not only am I calling you out on your bluff, but so far it has been proven that you have got it wrong on more than one occasion in this thread regarding resonance, and what resonance is in different systems.

You have provided no evidence what so ever that myself and others here are wrong.
These are all facts MH-there all right here on this thread. For you to deniegh them, is just proof of how delusional you really are.

The question now is-why do you continue to try and force those here to forget about things you cant explain you self?. Why the continual insistance that there is nothing special in something you know very little about?.
Why do you try and steer people away from things that have been proven to increase efficiency in systems.

Sorry MH, but you have now jumped out of the pot, and into the fire.
Cant wait to see your resulting answers to your own questions.
4 - 8 weeks to gather answers to your own questions MH--that says a lot about what you expect from others, and what you deem to be correct for your self.
Clear double standards MH, but would we expected anything less from you.

Brad:

The real victory would be if you and Smoky2 applied yourselves and arrived at the simple universal understanding of true resonance and answered the wine glass questions correctly and then applied that new knowledge to the so-called "resonant Joule Thief."

If you have nothing new to add then you may as well wait until next month and cede the floor to Magluvin and Smoky2.

well, if you would like to be specific, and explain where you think what I said was incorrect, I will be happy to explain it to you in greater detail.
so that you can understand and learn from it.

What I took your question to mean, is exactly the opposite of what everyone is showing you.
They show you how to "measure" the resonance that is occurring. Generally, by an outside mechanism.

The way I answered your questions, is the opposite of that.
i.e. - determining what the frequency "should be", given the factors involved.
When calculated, then the wine glass is set on the table, and filled to the appropriate level, with the proper density of fluid
   ---  this value should (in theory) be the same as measured by the various methods demonstrated by our peers.

I am not going to baby step you through the mathematics of congealed silicates, in their various chemical compositions
crystalline structure, density, grain lengths, dopants, thickness of the glass, dimensions of the resonant chamber formed by the goblet shape.
fluid mechanics of the liquid, be it oil, water, or some other medium.
Although it would be a great educational adventure for those wanting to increase their knowledge, it is a bit off-topic, and a lot of extra work just to prove a point to someone who doesn't bother to read..

you are dodging your own questions, and any proposed answer to them, with no explanation of yourself.

If my answer was NOT the answer you were looking for, perhaps you should rephrase the question,
or better yet, give us YOUR answer(s), and let us stand corrected.

and by the way - to everyone - you do NOT have to tap the wine glass at the resonant frequency to cause it to resonate.
ANY frequency will work, so be it that it is a consistent one.

you can rub your finger along the rim at different speeds
or tap it at different frequencies, stimulate with a speaker and tone generator, etc.

now, to BREAK the glass - yes, this does need to be the
"natural" resonant frequency of the glass system or a coherent (octave/multiple/divisor/interfering frequency node).
this is easier to deal with when the glass is empty - as air has very minimal effects as a medium.
consider the difference between the speed of sound in air, vs the speed of sound in a vacuum.
in an empty glass the natural resonant frequency is close to that of the resonant chamber, times a coefficient of the glass material.

apply this knowledge to the speed of sound in thick, dense fluid such as oil - and the change now has a significant value.
also, by filling the glass with a liquid, you are in effect, altering the size of the resonant chamber.
