Joule Thief 101

[MileHigh]

Wattsup:

You are welcome, and as long as you are stimulated and interested in what you are doing then I think that is a good thing.  However, there is a wide gulf between the way you think and people like Poynt99, Verpies, TK, Picowatt and myself and many others think.  I actually watched your recent clips and to comment on the non-technical side of things, I can see that you are a really good guy.

Also, we are just talking about the natural self-resonant frequency of the wine glass.  Simple, basic stuff - no frequency sweeping.

Anyway, I am curious to see what you will eventually have to say about the wire business, but don't be surprised if I comment that it will be the "same old - same old."

The concept of Resonance is a quite simple. Resonance was known about well before the use of electricity, and in fact it originally applied mainly to sound, the word resonance = to resound, the word has it's origin in Latin so it's that old. The electrical application of the word is fairly recent by those terms. It applies to electrical and mechanical vibration as well as sound because the action is virtually the same.

There is nothing free in resonance. It's an addition or a series of additions which cause a kind of amplification or magnification of a vibration of some kind, basically. Neither amplification nor magnification have anything directly to do with OU.

Resonance is a means to an end, or an operating state ect. All resonant systems that I can think of, have for all intents and purposes a continuous input, and losses as one of the main outputs.

I don't think we all need to be learning the stuff of Engineers or Physicists to be experimenting, but I think it does pay to be quite skeptical of our own results and those of others until such time as there is replication or proper analysis of any "claims".

I don't think there is much about a JT that is resonant unless the HV output has a sine wave form to it some how. I've built small tuned Tesla type coils with top loads that are resonant and did produce near perfect sine waves. And with pulsed DC input and using both a feedback oscillator as well as using a fixed frequency DC primary driver with a tuning method applied to the many turns secondary. I have achieved some interesting results with various set ups but probably the more interesting results do not come close to OU, they are interesting for other reasons.

pre-101 again

Since by definition the resonant frequency is when the amplitude increases,,

What do you call it when the frequency increases?

I would call that a change in conditions or physical properties that alter the natural resonating frequency. ie. a reduction of Inductance or capacitance in an electrical resonant circuit due to operation. Or the heating of the glass in the case of a resonating glass.

If your English is fine how come you say "meaning's" when you should say "meanings?"

That's it ?--that's the best you have MH ?.
If you know what i should have said,or how i should have said it,then you must of understood it-Yea?.

The joke is your "explanation" for the operation of the Cool Joule, which you avoided mentioning.

A generic answer MH,as you want in regards to your questions.
No point in talking too much to a horse,when the horse is dead.

Yes, you are going to wait for the answers.  Karma is a biatch considering you brought that one onto yourself.

Sorry !God!,but i will not be waiting for you to deliver any miracles.
We will see how you end up going with your Karma soon enough-->oh,that's !bitch! by the way,not biatch.

However, you can use that as an opportunity to teach yourself instead of being spoon fed the answers.

I do teach myself MH,and that is why i do not have to be swayed by babble like yours when it comes to experimenting.

I can't resist commenting on this doozy from you:
."

I see your up to your old tricks again MH--missing the rest of the post me thinks
It is clear that you do not understand English,or you just choose to be stupid.
My complete answer--The resonant frequency of a wine glass is determined by the value of the resistance in the system as a whole,where that resistance is seen as acting against/or limiting the frequency of the oscillations of the wine glass.
This resistance could be seen as being much the same as a governor system on an ICE,where the resistance governs(limits) the rate of change in the wine glass,and where a governor in an ICE governs(Limits) the RPM of that. ICE,where the oscillations would be denoted as the motion of the pistons.
You did not think to hard about your smart ass answer either-did you MH.
Quote: You are basically saying this,"The resonant frequency of a wine glass is determined by ... the frequency of the oscillations of the wine glass

You just cant think past your own silly little ideas inside your head,as you are dead set on trying to discredit me instead of thinking about what is actually taking place with the resonating wine glass.

A question for you MH.
We have an ICE that is fitted with a governor,and this governor is set to engage at a set RPM
The piston is moving back and forth/up and down(depending on motor design) in the cylinder--this is our oscillations.
What will determine the frequency of those oscillations (our RPM)?. The answer is the governor of course.
Now,here is my question to you--> what is it that determines when the governor will activate

So have another look at your smart ass comment MH--The resonant frequency of a wine glass is determined by ... the frequency of the oscillations of the wine-->and try to see a little further than your nose.

Take note again of what I said to you:  You have to teach yourself to effectively communicate a concept.

You have to read the whole paragraph,instead of doing a MH choppy choppy job on it.

Your answer about the resonant frequency is off by a country mile, and your sentence was nonsensical.  It was just like saying that the mechanism of resonance in a wine glass is when you hit it at its resonant frequency and it starts to resonate.  The model of the speed governor for an ICE has no relation at all with how the wine glass resonant frequency is determined.

Instead of plowing ahead like a steaming bull that's snorting fire and insisting that you are right, why not just spend some time learning about resonance?  You may indeed have a "Eureka!" moment, you never know.  Or someone else will answer the two questions.  This is supposed to be a challenge to encourage you to learn and apply your knowledge, not an insane Mad Max battle in the desert.

P.S.:  I spelt it as "biatch" intentionally.
