Joule Thief 101

[MileHigh]

Dear Bill.

How many more posts are you going to tolerate with the obscene language ?

All should remember that OU. Com is open to all ages, my grandchildren look in from time to time because their " wacky " grandad posts occasionally.

I'm sure dear Groundloop would have stepped in a lot sooner!

I'm no prude but...... Enough is enough.

Kind regards, Grum.

I apologize for that. The problem is that Brad's behaviour for a long time has been a complete and total sham and it's fatiguing and it's tempting to call it out sometimes.

Well i can see that you did not agree to Bills request to stop with the vulgarity--you really are a disgusting old man. You really do turn into something else when you are wrong.

The arguing from a few here is appalling.

This is what i mean--your limited understanding regarding phase,and what it is.

MH knows what phase is.

You say there is no time difference,and so there is no real phase shift--well that is just plain wrong--incorrect MH--try again.

Is that what he is saying? I don't think so.

Depending on the situation, two signals can be in or out of phase, with or without a discrete time shift. I think you are both correct, but you are seemingly talking different languages to describe the same effect.

The 90 degree phase shift between current and voltage in a capacitor or inductor is not caused by a discrete delay (time shift), but the effect is the same. It is simply differentiation and integration. Same goes for the transformer being discussed.

One can also create a phase shift between two signals by using a true discrete delay (one that is not frequency dependent, and not dependent on the phase relationship between current and voltage in a reactive component).

Wattsup:

Your "half coil syndrome" is nothing more than a variation in the strength of the AC electrical field relative to ground as you sweep your tape head from the side of the coil with high AC potential to lower AC potential, and then to ground.  The coils you play with on your bench are doing nothing more than acting like AC voltage dividers and your tape head is picking that up.  There is no "half coil syndrome."  It's a fallacy to say that there is "more energy" on one half of a coil relative to the other half.  It's completely ridiculous.  Every loop of the coil subtends a magnetic field and all of the magnetic fields add together.  When you energize a coll with AC, each loop of the coil is "stacked" on top of the adjacent loop in terms of voltage.  When you sweep your tape head back and forth, you are going up and down the AC voltage stack.

That's all there is to it.  That's what you are seeing.

Sorry, I am not here to debate the "big issues" that you made your speech about.  Believe what you want to believe.

Post 1902-quote: As I alluded to before, the "phase shift" is not even real - there is no phase shift. It's just an abstraction we use to make it easier to describe sinusoidal-type waveforms you see on your scope display There is no true "phase shift" if you interpret "phase shift" as meaning "shifted in time.

There dose not have to be an overall time difference for each cycle for one thing to be out of phase with another. You need to go back to basics MH--perhaps review two children swinging on two swings of the same kind,but where one child starts swinging first,and the second starts when the first has reached the point of 1/2 a cycle. The child that started his swing first will always be say 2 seconds in front,and there phase can be said to be 180* out,but where there cycle time is still the same for each cycle. When the first child stops swinging at his starting point,the second child will not reach that point for another two second,but still there cycle were  exactly the same.

You say there is no time difference,and so there is no real phase shift--well that is just plain wrong--incorrect MH--try again.

P.S--Is minnie your son?--just asking

Well, I was fed up with your nonsense and I used tough language and I won't do it again.

"limited understanding"  "just plain wrong"

It just goes on and on and on.  What I stated was perfectly correct.  You were just spinning the same old lines, it's vulgar and gratuitous and nonsensical.  It's behaviour that is beyond ridiculous.  You did it just for the sake of doing it when you knew full well that there was nothing "wrong" in what I was stating.  You are just uttering propaganda for the sake of uttering propaganda.

The truth is that although you have been slowly getting up the learning curve, there are still many pregnant jaw-dropping pauses where you inadvertently reveal how limited and/or skewed your understanding is.  When you started playing your "wrong again" game with me you got the truth from me.  You get the truth from me about your limitations because you keep lying about me.

Look at your explanation for the question about how a wine glass resonates and the mechanism for the resonance.  To paraphrase, "a wine glass resonates by hitting it at the resonant frequency and it starts to resonate" is a joke.  It's a jaw-dropping example of the fact that although you are making progress, sometimes you are still completely clueless.  You are in no position to drone on falsely claiming over and over that I don't know what I am talking about.  It's grotesque and vulgar behaviour and it's all a lie.

You mocked my answers for the two wine glass questions when the answers that I provided are perfectly correct.  You are making a vulgar spectacle of yourself.  You were called out early in the thread for mistakes and now you have gone full haywire.  It's ridiculous and you have no shame.

So that's why you were called a bad name.  You are like the disruptive kid in the class going on and on and on driving all the other students and the teacher nuts.  Now when is it going to stop?  Your whole "pitch" about me is a complete lie.  I might not be perfect, but your little strategy is a dark stain on your character.  It's your irrational reaction to being held to a normal standard.

So when is it going to stop?
