Forget it, somebody already mentioned something about spoon feeding and I am not going there.  Spoon feeding and knowledge retention are seemingly opposites.

Think about all of the threads and the thousands and thousands of postings about driving a stand-alone coil at its self-resonant frequency.  I am not even talking about a Joule Thief here.  How many times have you seen Tesla's patent posted?  Think of all of the buzz and speculation about that, the thousands of hours devoted to that subject.

After all of that talk and energy expended and all of the experiments done, have you ever seen any tangible results with respect to that?  I haven't myself.

So you have resonance and self-resonance being discussed for years, and from what I can see not a single tangle result except for those big resonant coils that give off the big electric arcs.  There are even those entertainment companies that rent them out for parties and raves and they modulate them to play music.  There are a ton of clips on YouTube.  Lynyrd Skynyrd anyone?

Hey, take what is a pulse switching circuit and imagine that you can muck up the way it operates and hope for better results.  Why imagine a pulse circuit can "resonate" when apparently you can't even define what that actually means for the pulse circuit, and to take it one step further, you don't even know what resonance actually is?  It's the blind leading the blind.

Why not just design some kind of circuit built around a purpose-designed oscillator and then do the same old tired transistor modulation (instead of switching) of a coil to light an LED?

So forget it for me, this thread has reached a dead end, the bus driver doesn't know how to drive the bus.  Go back to driving school.  I will just sit on the sidelines and see if the bus actually goes anywhere or if the thread dies out with a host of unanswered questions about our favourite subject - good ol' resonance.

Threads like this really do give others the chance to see the caricature of fellow threaders.
I mean,the last couple of pages alone on this thread have been a hoot

Quote Webby :Tinman answered the wine glass question,, now it is your turn.
Now be specific, and put substance behind your words.

MHs reply: Forget it,

  So predictable and expected.
Has anyone here seen MH answer even one of his own question's ?
Of course not,as he knows he cannot answer any of them with the provided information contained within his own questions.

MH ask: how do you determine the resonant frequency of a wine glass?
My reply-- there are a multitude of things that will determine the resonant frequency of that wine glass--there is no one simple MH equation that can be used to calculate that resonant frequency.
What grade of crystal is the wine glass made of MH ?.
What are the specifications on the physical size and parameters of the glass?.
MHs response -->You don't have the slightest clue.
Quote HowStuffWorks- Resonance, An object free to vibrate tends to do so at a specific rate called the object's natural, or resonant, frequency. (This frequency depends on the size, shape, and composition of the object.)
Conclusion--my questions were valid---MHs question was incomplete,and loaded.

Quote MH: Why imagine a pulse circuit can "resonate" when apparently you can't even define what that actually means for the pulse circuit, and to take it one step further, you don't even know what resonance actually is?  It's the blind leading the blind.

Another question he cannot and has not answered him self.

Quote MH: So forget it for me, this thread has reached a dead end, the bus driver doesn't know how to drive the bus.

Seems the self appointed driving instructor dosnt even know what a bus is

Quote MH:  I will just sit on the sidelines and see if the bus actually goes anywhere or if the thread dies out with a host of unanswered questions about our favourite subject - good ol' resonance.

Yes,unanswered questions that the provider of those questions cannot even answer him self--hey MH.

Quote MH: Then there is something like the Cone of Silence.

Yes,one you stick to MH,when it comes time to answer your own question's.


Quote MH: When somebody says something that many people know is totally wrong those people won't say anything because they are wearing the Straitjacket.

Example of totally wrong-->No, an ICE doesn't resonate in any way, shape or form whatsoever
My reply-->There is so many resonant factors in a two stroke engine that can increase it's performance, it's not funny
Good thing im not one that wears the good old straight jacket-hey MH

Quote MH:"Induced current into the inductor" and the "rise of the magnetic field" are the same thing.

Oh dear

So MH--What dose determine the resonant frequency of a wine glass?
Time to put your money where your mouth is.<-- my guess is that you wont even try to answer your own question,as we have seen on every occasion so far.
The driving instructor that dosnt know what a bus is,but happy to ridicule those that cannot drive one.

By the way. Below is a pick of my old rig,taken just before i left for a long haul trip.
I dont think driving the bus is going to be a problem

....gotta delurk and reply.
road trains in OZ are friggin mind blowing. theres the TV show outback truckers ,  4 - 5 trailers and nothing but dirt , mud , rivers , hills and goat tracks!!

Ive made push pull with arcing FBT before using search coils .  electrical resonance is input signal is equal to feed back signal , the coil and core finds resonance

I am actually in one of the outback truckers shows lol.
Got paid an extra $700.00 just for appearing in the show--along with two other long haulers.

You can stew in your juices for a month or two and I will answer then.  Sorry, but your BS has been exposed.  Here you are arguing about resonance and you can't even explain what it is for a bloody wine glass.  The whole debate with you has been an exercise in BS and bluster and the usual baiting and switching.  It's been a farce.  I have seen it many times now.

Even alleging that I can't answer my own questions is just a BS charade once again in an attempt to save face, because you know I can answer them.  Delivery in four to eight weeks.

This is probably the best film you will ever see on the Tacoma Narrows bridge:

Galloping Gertie - The Collapse of the Tacoma Narrows Bridge

https://www.youtube.com/watch?v=KqqyAZDpV6c

What's truly amazing is that I think it was done by high school students.

It's so good that I will give them credit right here:

Galloping Gertie -- The Collapse of the Tacoma Narrows Bridge examines the creation and demise of the original Tacoma Narrows Bridge. Produced by Koyo Kim and Raluca Ifrim for National History Day 2007.

From WSHS' collections. Catalog ID: 2011.41.1.2

There are a lot of lessons to be learned in this clip and they can be applied to this forum and to this very thread.

MileHigh

It is important that those thinking along these lines grasp the concept entirely.

"what is" or "what is not" resonance.
This can be the cause of a great deal of confusion.

Synchronization, or Timing of the components of a system, while may be required for total system resonance, these are independent concepts.
timing can be coordinated at virtually any range of frequencies, velocities rpm, etc.

resonance results in things like TK shows with the bridge above.

the inductance, number of turns in the coil, resistance, transistor function
these things are the "timing".

resonance has to do with the length of wire in those coils, vs the physical size of the ferrite (times a materials constant)
vs the comparable impedances and capacitances in other parts of the circuit.

when both of these line up together in just the right way, we see things like TK's bridge example, occurring in our circuits.


PS: if you want to see an "ICE in resonance", sit behind a large diesel truck on "just the right sized bridge" for long enough, and the whole bridge will start to bounce

You give your self too much credit MH. Believe me when i say that there will no stewing here ,other than to cook my wife a nice meal. I need not your answers MH,but i am surprised it would take you so long to carry out the research needed by your self to put the answers together.

Sorry, but your BS has been exposed.

Those that read this thread will see where the bullshit is coming from MH--let them be the judges of that.

Here you are arguing about resonance and you can't even explain what it is for a bloody wine glass.

I have answered this question many time's MH,but as you have done in the past(many times on this thread alone),you miss it,and then accuse people of not answering questions.
I have proven you wrong time and time again on this thread alone--it's all there to see,and people can judge for them self.

The whole debate with you has been an exercise in BS and bluster and the usual baiting and switching.  It's been a farce.  I have seen it many times now.

Ah,so you do look in the mirror MH.
The facts are(and are written in this thread for all to read),i gave an accurate description as to how a JT operates at low voltage potentials--you couldnt even give it a try,because you had no idea>--you admitted to this
Then i had to set you straight about the resonant systems in an ICE-->as you got that wrong as well.
There is also the fact that you cannot answer your own questions(not one)--which i have accurately.
You cant grasp the fact that resonance can increase system efficiency's --even though many examples of such have been provided. Some devices will not even work outside there resonant frequency. Im not sure who it was,but i believe some pages back i saw some mention a pulse jet engine. The valveless pulse jet engine always runs at it's natural mechanical/acustic  resonant frequency.

Even alleging that I can't answer my own questions is just a BS charade once again in an attempt to save face, because you know I can answer them.Delivery in four to eight weeks.

Dropped your self in that pile-didnt you MH.
Some one that has answers dose not need 4 to 8 weeks to answer them lol.
Some one that has no answers would require such time to gather the information needed to answer such questions
Curve ball-->You can stew in your juices for a month or two and I will answer then
Predictable from some one that cannot provide the required information.

Post 557 :Also work on your personal integrity with that farce of a response from you about the resonant frequency of a wine glass.

Current post :Delivery on answers in four to eight weeks

  Lol

First you want to know how a wine glass resonates  .
Then you want to know what determines the resonant frequency of a wine glass-->how long is a piece of string question:D
Now you want to know what is resonance in a wine glass
The last question you only ask in the post of this reply,and yet say i have not answered it
You need to work out what you want to know MH,and i will give you the answer--but only if the question can be answered with the provided information--none of your incomplete or loaded questions will be taken notice of from now on MH. So please provide all the required information about the systems parameters,so as we can make an accurate working description--you know,just like you ask from us.

Resonance in a wine glass ,is the wine glass vibrating at it's natural resonant frequency
Now i have highlighted that in red,in the hope that you dont miss it.

Now-do you think that a JTs core will be vibrating at it's natural resonant frequency?
What impact would it have on the efficiency if the running frequency is the same as the NRF of the core?.
Dont worry about trying to answer those questions either MH,as we dont have 12-18 months to wait
