Only 5 min., Dutch 20 years guy, old and 2 times World-Champion,
look same driver fast driving on a 2- and on 4-stroke machine,
so good / nice to hear the different resonance's!

Begin is 4-stroke, and at 3 min comes the 2-stroke:

--------------------------------

Please: Lets talk about: 0.2-0.3 volts JT with a tor and a resonator!!!

Very cool.  I know the 2 strokes have the power/weight advantage but, I still like the sound of a 4 stroke engine better.

Here is a photo of my 4 stroke 49cc scoot.  It does not pull wheelies but it gets over 100 mpg.


Bill

PS  It has over 4,500 miles on it.

A while back you took on the strategy of "since he is telling me I am wrong about stuff, I will tell him he is wrong about everything and heap it on."  It's painful to watch.

What i took on MH,is to put an end to your negativity and incorrectness,in a hope that others will not give up based around the falsehoods you present.

 
Quote
The stuff about the car's top speed is ridiculous and painful to watch.  I brought up that to give you a simple analogy to show you that you could answer the question about determining the resonant frequency of the wine glass without measuring it (ridiculous) or having any specifics.

I understand that MH,but you dont seem to understand that if you are going to make such presentations about simple analogies,then they have to be complete in order to be correct. Your analogy is incorrect,as you have included an assumption that others using it will assume that the road surface the car is to be traveling on is level/flat. For it to be complete and correct,then you simply add the gravitational factor in,and everything is accounted for.
I bet you cannot show me one of your books that says assumptions are ok in making accurate  determinations.

Quote
These are concepts that a 15-year-old will easily understand so why can't you?

Any 15 year old will know that a car will go faster down hill than it will on a flat road,and so there go's your accurate determination of the cars top speed.

Quote
The car speed and the wine glass resonant frequency are two examples of you disrupting the thread.  Both of them should not even be issues at all yet 10 or more pages have been devoted to these non issues.  You are making people cringe.

What i am doing,is showing people that you cannot think things through properly or completely,and that your word is in no way a determination of how things will turn out.
The cars top speed was your input,and yours alone,and i pointed out your required missing data.

Quote
The big fat lie is to say, "Everything this !!teacher!! has said so far -in this thread alone,has been incorrect."  You are preposterous and there are other outright lies and I am sure many people have spotted them.

Quote
No, an ICE doesn't resonate in any way, shape or form whatsoever.

Thats what i would call a lie MH.

Quote
You have really dug yourself into a hole, your brain is frying.  You have been having one good long tantrum in this debate, and it's an ugly spectacle.

MH
I can assure you that i am having no such tantrum. What i am trying to do is make people aware of your way's--and it seems you are helping me do so.

Quote
You are the main cause of the disturbance in this thread because I decided to treat you as a 100% normal person that had to understand normal things that other normal people understand

Well it seems that i understand !!normal!! things a little better than you do MH,and that much is evident in this thread. I am also seeing no others here agreeing with you as of yet.

Quote
Getting you to accept a question that a normal person would not have any issue with and not giving you a "special pass" led to you ranting and raving and disturbing the thread.

What i see here MH,is people answering your questions (myself,smOKy,ETC) with our own thought's,and then backing up those answers by way of research (google),and you saying we are all wrong. Then i read that you answered your own questions by way of your own thoughts,and then did some 20 minute google research,and your answers are correct. So how is it that all of our thought's and google research are incorrect,but your thought's and google research are correct?.

Quote
I get it now, an ICE can have Helmholtz resonators on the air intake and exhaust to improve the air flow into and out of the cylinder.  I get it, I learned something new, and I acknowledge it.

This is good MH--we are slowly teaching you ;)

Quote
I never claimed to be an expert about car engines, and if you had just explained yourself properly it would never have been an issue in the first place.  It's not an issue anymore.  It's too bad that you can't do that.

I explained myself very clearly MH,but some how you got timing confused with resonance.
Remember MH--it was you that got confused with the difference between timing and resonance,and it was because of your mistake that the resonance issue in ICEs came about.
My exact words were Quote post 510: I dont think you grasp the reasoning behind resonance. The reasoning being much the same to that of having the timing correct in an ICE engine-done for best performance.
So am i incorrect MH?,is the timing not critical in both cases in order to achieve best performance/efficiency?.

Quote
Look in the mirror and see Brad's brain fry and kiss my ass

My brain is fine thank you MH. But it appears that yours is starting to take on a little more--learning is a good thing.

Quote
Pull yourself together and do some research and try to answer the two questions.

As far as im concerned,my answers are correct--along with smOKy's,as his are much the same as mine ;)

Quote
The answers are ridiculously simple.

As were the resonant factors in an ICE,and the determination of a car's yop speed--but you got both them wrong MH.

Quote
The only thing I want to hear from you are answers to the two questions.  Anything else at this point would be useless and just disrupt the thread.

You have my answer's--many of them--and that's all you get.
The only disruption MH,is you and your silly 4 to 8 weeks posting !your! answer's,and then having the balls to say--we should be debating this. How do we have a debate when you do not provided any input toward the debate?.

Please point out where i have been wrong in this thread MH--that is backed up with actual proof,and not a MH assumption.

Brad:

I am not going to deal with your nonsensical BS and parroting and mirroring of what I say anymore.

Here are the two questions:

How does a wine glass resonate, what is the mechanism?
How is the resonant frequency of a wine glass determined?

Nobody has gotten the answers correct yet.  I am requesting simple answers of four sentences or less in your own words.  It would be a very worthwhile thing to understand mechanical resonance considering you want to look for resonance in a Joule Thief.

You will indeed wait for the answers if nobody gets them, and the wait is due to your own bad behaviour coming back and biting you in the ass.  Karma is a bitch.

Anyway....

Here is my new wrap.  Used 26awg, 11 turns on each side. Used that new glue they show on tv that cures with the UV flashlight. Not the same brand as the flashlight looks like a lil maglight and the glue is in a separate bottle. The stuff would never fix the broken cable to pull that truck on tv, but it is cure on demand not like super glue.
but it was great for this to keep the windings in place.

Besides the fact that it is not nonsensical BS,i agree. I simply do not have the time to go around and correct all your mistakes and misdirection attempts anymore MH.

Quote

How is the resonant frequency of a wine glass determined?

Both answered.
But what happened to the other question MH?--!What! determines the resonant frequency of a wine glass?. I mean,wasn't that what your bungled attempt at determining a cars top speed all about?.

Quote
Nobody has gotten the answers correct yet.

How have you determined this?.
Where is your scientific method that precedes that of what the rest of us used to answer your question's.

Quote
It would be a very worthwhile thing to understand mechanical resonance considering you want to look for resonance in a Joule Thief.

I think i understand it better than you think MH,and that is why i was able to correct your incorrect answer about the resonant systems within an ICE.
I think maybe it is you that needs a higher understanding of what resonance is MH--not the rest of us here.

Quote
You will indeed wait for the answers if nobody gets them,

MH
I am sorry to inform you,but i am waiting for nothing from you. Your track record here in this thread is way down,and your knowledge about what resonance is, is lacking in scope.
I can assure you that i will be paying no attention to your answer--for many reasons.
You had no idea about resonant systems within an ICE,and how they increase efficiency.
You bungled up your own example of determining a cars top speed.
You told us all that we are all wrong,and based that on your own thought's--only after did you go have a google(for a whole 20 minutes) to try and find something that may fit your own theory.
So i can assure you that i am not waiting for !your! answers MH,as we here on this thread already have the correct one's-->but thanks anyway.

 
Quote
and the wait is due to your own bad behaviour coming back and biting you in the ass.  Karma is a bitch.

Oh come on MH,you put your foot in your mouth this time.
Onle a couple of pages back,you mentioned that you (later on) did a 20 minute google search,and found something that is suppose to back up your !theory!.
So it is clear that the 4 to 8 weeks thing is for the very reason i said it was for-->it gave you the time to try and find the answer's to your own question's--as all you had before was theories--your own thought's.

So stop with the bullshit MH,as you have really outsmarted your self on this one.
But even knowing that,you still continue to dig your self a deeper hole  :o

Anyway,we are done MH--i have no more time for your idiocracies.

That's just another round of the same old disingenuous poseur BS that we are all very used to by now.  It's like you are a carny trying to sell yourself and hype your concession but the game is rigged.  Stay tuned.

MH
You may say what you like,but the proof is in the pudding ;)

It is clear as to who in this thread has a good understanding on what resonance is,and where it can be found. You on the other hand seem to be lagging behind a little,and i think when people like smOKy start to dish out the real mechanisms behind resonance,you fall flat on your face--and this annoy's you-the fact that you are being outdone. So you have come up with some sort of diversion to try and save face. Thats all good MH,but like i said,i am not interested in !your! answers,as i already have the answers i need.

So thanks-but no thanks MH.

So far after some time consuming resistance scanning in the sine zone of circuit operation, havnt found any resonant freq going on other than the battery with the 4 disk caps. 1.64mhz. Probably each battery has a diff inductance due to charge level affecting it, and other factors. Will look into that.

Below are scope shots of the coil shown today with 1 shorted winding trying to reach the freq of the battery with the caps. The first one is tuning the resistor just before the resonant freq.  The second is at the resonant freq, and the 3rd is tuned after the resonant freq. You can see the yellow trace of the led is higher when at the battery/cap freq.

Hey Bill

What were some of the higher freq you remember from back then?

Looking at Lasersabers builds. Seems some details are left out like winding turns on some. He calls it the joule ringer. I winder if his are operating at some resonance in the transformers. He seems to have gone up to higher numbers of turns which should allow lower freq of operation. I just seem to not be getting there. 

Im trying some new things Ive come up with and see what I get. Then I gota git.

Mags, how come you shorted the extra winding rather than place a cap across it ? If you have a shorted winding and you know it's inductance when open as well as the operating frequency then you should be able to determine the correct capacitor so as to create a "resonant tank" rather than short that winding. The battery cap wave is kinda cool.

Hey Farmhand
Seems Im only getting up to under 300khz without the shorted one and some other core/windings up to poss 800khz. The added shorted turn takes me at times just over 2mhz. Just did it to get up to the freq range of the battery with the caps. Like if the circuit were to be driven at a freq(a freq without the shorted winding) and then added the shorted winding, the switching circuit would not self adjust and the shorted winding would become an excessive load. But when the circuit reacts to just a lower inductance, the freq of operation jumps accordingly. Demo'd that earlier one when I jumped in here.

Tried the cap on the shorted winding, and it was too low of a freq compared to the 1 turn shorted. The shorted turn actually makes the led brighter at lower resistance at the base. More input also, but havnt tested if the increase in input is mostly to the led or the winding is soaking it up yet. Just throwing thoughts around with it.  Only killed 1 led so far. 3904 keeps going.

The battery oscillating seems like a cool thing to add to the whole. If I can get the windings to ring with the battery/cap, things should be in total sync. Dunno yet

Would have to get a variable cap to tune a winding. lookin into it.
