Joule Thief 101

[poynt99]

... oscillating at the natural frequency

Can be replaced by a single word; "resonating".

Thanks for your colour commentary but the intentions were good and Brad got a lesson in what resonance really is as evidenced by the fact that he was unable to answer the two questions.

Another lie.
In fact,i answered the questions in a more correct manor than you did MH. I used the !correct! scientific definition,while you were happy with your !laypersons! terms.

I probably will never do anything like this again as I have clearly stated what I am really here for.

Yes-to spreed dis/info,and tell other members not to help a fellow member when he requests it.

In this thread we looked at what resonance really is

,

Yes,we did. It is when a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency.

If you are going to investigate a "resonant Joule Thief" now you know what to look for.

Yes-look for MHs JT,as it requires no external force (E.G-battery) for it to resonate.

Keep on with that doting.  For sure you are going to hit the jackpot and change the world and your name will get into the history books.

Well,maybe not the history book's MH,but you could dust off your old book's,and pop in a note or two on the resonant systems that exist in and around the ICE to increase efficiency and power. Maybe make a small note on what a J/FET is while your at it.

I re-read Poynt's post 2009-
Quote: You expect to be cut some slack with your incorrectly depicted probe positions and scope traces, so I suggest you do the same for MH for assuming that energy has already been given to a resonant system. In fact a resonant system is resonant regardless if it is resonating or not.

So i will dismiss the fact that the probe positions were exactly where i wanted them to be,and there for correct for the experiment,and i do understand that a resonant system is a resonant system regardless of whether it is resonating or not(a car is a car whether it is moving or not). But as long as you insist that my !!English!! has to be 100% perfect,i will insist that such a simple concept as resonance is presented correctly by you MH.
A wine glass will only resonate while the external force is acting upon it. If that primary part of the system is missing,then the wine glass will oscillate,and ring down until it is at it's rest state.

You are hopeless Brad and I don't know if it is because you are clueless or malevolent or a combination of the two.  You certainly have an issue with mendacity.

[Magluvin]

Thats it. Ive had it. I quit.  Im handing in my resination.

that was a good one  !!

Are you being mendacious ??
