Joule Thief 101

[Magluvin]

Whether its a wine glass, a bell or a cap and coil, the resonant freq of each shows 'increased activity', without increased input. 
Thats what Im interested in.

When I think of Teslas Peirce Arrow, he had an AC motor under the hood, 3 ft wide 2 ft long if I remember correctly.  Now if the windings in that 'AC' motor had a resonant freq, then if the input were to operate those windings at their 'AC' resonant freq, then it would seem the motor would have 'increased activity' with that input, compared to running it at other freq other than lower multiples of that resonant freq.  Most likely that 'increased activity' would be greater with an input of the windings resonant freq rather than even a multiple of it...

Brad:

Here is the first reference I could find that you made to an ICE.

Webby linked to a short article about using a air resonator to improve the air intake cycle.  The article had a diagram and a description and made sense.  What you say above is meaningless because you offer no details whatsoever.  Without details I took "timing" to mean the most common reference for timing, the spark plug timing, and there is resonance in that.

So with your absolutely abysmal communication skills of course you are going to get into trouble all the time because you can't convey information properly and consequently people can't understand you properly.  It's a serious serious problem that you have and you should do something about it.

Going back to the resonators for improving the air intake cycle, they aren't making use of resonance in a continuous cycle, they are more one-shot devices that are slaved to the timing of the pistons.

That is just a bunch of useless trash talk and everybody knows it's useless trash talk.  All that you do is hurt yourself when you carry on like that.

So why don't you just link to your preferred answers to the two questions or just answer them here in your own words and I will consider that your "final answer."  You have tried to answer three or four times so I don't know which is the one you want to stand by.  But if you are going to link then don't link to something with a bunch of Google copy/pastes, that is not a valid answer.

Once again, you just cant associate one example with another-can you MH.
How can you not see that both show an increase in system efficiency.
If you operate a system such as a JT type system in it's natural resonant frequency, you will increase the efficiency of that system.
This is much the same as having the correct timing in an ICE, where the correct timing will also increase the efficiency of that system.
Can you not understand that the switching timing of the transistor needs to be correct in order for that JT type circuit to run at it' natural resonant frequency.
Both systems need to have correct timing in order for both systems to operate at there peak efficiencies.

Man-talk about having to spoon feed.

MH
So I noticed you ignored my comment regarding friction being what determines the resonant frequency of a wine glass.

Is this what your big answer is going to be?

for the first time in 25 pages, I am going to have to agree with MH here.
his perspective on the "resonance" of an ICE is perfectly valid.
Noone thus far, has shown an ICE in "resonance".

and while I DO feel that I answered his questions validly, concerning the Wine Glass,
I, Myself, was not the one he requested to do so,,,
and thus, the answers were in "my own words", not the own words of whom he requested the answer from.

synchronization is NOT resonance, although it "can be", it is not necessarily so.
things can synchronize, with respect to ratios, and a division there-of.
But this is not always resonance.
In fact, in the case of the two-stroke engine, which resonates at 1/2 wavelength of the engine.....
ONLY the odd harmonics are "resonant".
which discludes 50% of all synchronous frequencies by default.

If you do not understand this, go back a page or two and read what I posted about the Joule Thief, and ?Wine glass.
two-stroke engine also falls into this same category.
Which I am sure, is the reason it was suggested instead of the more common 4 or 6 cylinder engine.

[sm0ky2]

for those of you who wish to truly understand "resonance":
a 4-cylinder engine represents the 1/4 wavelength, like 1/2 of the JT circuit. (mismatched impedance)
1/4 is the 3rd resonant freq of the 1/2, as is the 1/2 to its' 6th resonant freq of the ferrite.

Thus, it is easier to get a 4-banger to "resonate", than it is a two-stroke engine.
I would explain this further, but it is quite frankly, irrelevant.
For a two-stroke ICE to become "resonant", we have to redesign the entire system to do so.
It is not just some random RPM that the engine achieves.
the problem is much more complicated than that.
