Joule Thief 101

Well, that was quite a ride and it revealed a lot about the dark side of human nature.

What's interesting is that I lucked out on my wine glass question in the sense that you can't just plug the question into Google and in 0.012 seconds get the perfect answer spat back at you.  You actually have to know your stuff and apply your knowledge to successfully answer the two questions.  Google is not going to readily spoon feed an answer back to you.  And that frustrated our contenders, I am sure.

Ironically enough, a resonating wine glass is just a mechanical version of an LC tank circuit.  L = the spring and associated stiffness of the glass, and C = the glass itself and associated mass of the glass.  Nothing could be simpler, and nobody got it.

Coming from you MH I will take that as a compliment!

I do not lie MH,, it takes more effort to lie than I am willing to put forward.

You lied and you spat out junk - the darker side of human nature revealed.

Her are my answers again:

Wine Glass Questions - Answered

How does a wine glass resonate, what is the mechanism?

The wine glass resonates by cycling energy back and forth between two forms, kinetic energy and potential energy.  The instant when the glass is not deformed, the glass is moving at a maximum velocity and all of the energy is stored as kinetic energy in the form of a moving mass.  The instant when the glass is at its maximum deformation, the glass has stopped moving and all of the energy is stored as potential energy in the form of a compressed spring.  In between these two states, the energy is stored as combination of kinetic energy and potential energy.

How is the resonant frequency of a wine glass determined?

The resonant frequency of a wine glass is determined by a combination of the effective moving mass of the glass and the effective stiffness of the glass interacting with each other.  The higher the effective moving mass of the glass, the lower the resonant frequency.  The higher the effective stiffness the glass, the higher the resonant frequency.

Now look at this clip:  https://www.youtube.com/watch?v=XggxeuFDaDU

Then ask yourself these questions:

How does the bridge resonate, what is the mechanism?

How is the resonant frequency of the bridge determined?

Are there any light bulbs going off in people's heads?  Who has the courage to say something positive?  Or are you all just submissive sheep and afraid to say that you learned something interesting and useful that can be applied to other situations because Big Bad Brad is watching?

@MH

GFYS. Your mouth extends far beyond your little brain squeeze and I understand that causes some to see no further then their noses. Could say more but you do not deserve it. I'll just let you keep fooling yourself and find out the truth when the standard model falls. Because it will fall. You are just blabbering about on borrowed time. All constructs meet their end eventually so you still can play the big man until you can't anymore. hahaha

@tinman

So many vids. Which to talk about. Who knows. During the major ruckus I have done a few days of JTing with a good 6-7 different coils and all do different effects. I will now build a coil just for the JT.

About your last vid. I suggest you take the coil and now try it sideways against the magnet swing instead of having it TDC to the core centered have it TDC to the side of the coil so the magnet cuts across the vertical wires of the coil. I downloaded your video to see it in slow motion with my virtualdub program. In slow motion you see things that you cannot see at normal speeds. I find that this is one of the most wasteful methods of passing a magnet beside a coil as you showed with the coil placed with its circle facing the passing magnet. If you saw from how far the  magnet can "influence" the coil, you will realize that before it gets even closer it is already influencing the other side of the round facing coil and this produces so much cancellation that this is why you get that waveform you see. It is the result of a great war between two sides of the same coil being inversely influenced at the same time. Your waveform shows the winner of that fight. 

I think you are better to have a complete cooperation of only one side of the coil then to have it face on with two inversed forces so just by pivoting the coil 90 degrees and pass the magnet on its side.

I could start talking about exactly what is happening in the coil and discuss how can electron flow do this type of effect with a magical field influence but since you guys are still in "it's the field" mode, I won't say more. hahaha

PS: @MH - For all the grief you gave everyone here about your f'n wine glass, for absolutely nothing, so just shove it where the sun don't shine. You have now lost my respect. You are simply disgusting to have put everyone through all this crap for a bullshit explanation. You need help.

In the quoted posting above, you make yourself look like a fool with scrambled brains.  It's enough to make a grown man cry.

The truth always hurt's some MH.
I feel your pain.

There is nothing in the question about the wine glass receiving energy.  Is this a failure on your part to think?

The question is--how dose a wine glass resonate--what is the mechanism?
Well the very first thing that happens MH,is it receives energy from an out side source--the very first part of the mechanism MH. No energy input-no resonating.

Er-wrong again my ass.  The question does not ask about energy dissipation, it just asks how the wine glass resonates.  Don't you dare get into one of your insane "car on a hill" arguments.  It's yet another failure on your part to think.

Sorry MH,but you bought the energy thing into this your self. Quote !!!ALL!!! the energy is then stored as kinetic energy.--->No MH,some is dissipated--all energy is not (NOT) stored as kinetic energy-->you got it wrong.

You never answered the two questions completely and properly.

As it turns out,your two questions were answered more completely and correctly than you did in your big reveal lol.-->You missed two of the most important part--energy received--energy dissipated lol.

No, I'm afraid SO.  You are stepping outside the bounds of the question again.  It's nonsensical idiocy like that that would get you sliced to pieces in no time on a serious electronics or physics forum.  They would think you were nuts.

I think most here are starting to see who is nut's here MH.
No resonant systems around an ICE
No resonant systems within an ICE
Your silly J/FET device makes no sense
And so on,and so on,-----

But you don't actually say the correct thing in your answer, you are just re-spinning your words in an attempt to make them fit.  I don't give a rat's ass if "the structure of the glass/crystal that the wine glass is made from" will determine the stiffness.  You did not say stiffness and it was never in your mind.  Stop the BS.

Stiffness is the incorrect term to use. Elasticity would be the correct term to use,and guess what MH,i used that very word to explain your questions many many posts back lol.

You completely failed to answer the two questions, mister "resonance researcher."  You were all pumped up with attitude at the beginning of this thread about resonance and as it turned out your puffed up chest was a fake because you could not articulate how a wine glass resonates, or how its resonant frequency is determined.

Sorry MH,but myself,smokey and others gave more accurate descriptions than your big reveal did,as we included energy received,and energy dissipation,and used correct terms like elasticity in stead of !!stiffness!!.

Based on what we have seen, you would be the laughing stock on any serious electronics forum.  The Tinman is only cool when he is in his cocoon on this forum.  You would be eaten alive elsewhere.  That's the harsh truth.

Based on what we have seen,you are delusional.
This thread is full of your mistakes,and i bet you are hard pressed to find one instant where you have had to correct me,as most of the thread is me correcting you--and even you correcting your self lol.

You have your self a nice day now MH.
