Joule Thief

[jeanna]

Paul,
Your last drawing was correct.

Gadget is a radio guy.
They have an understanding of turning wires that most people do not.

I am glad spice has a joule thief, now how about it?
Make a real one.
Then you can smile because you have a bright light that is almost free.
When you add many many lights in series to the secondary as many of us have, you will smile broader because you will have MANY lights for almost free.

However you do this, I hope you
Enjoy your day.

In all fairness to the guy selling the bcaps on ebay, this should be posted in all fairness. He wrote back saying,

"Dear paullowrance,

If that was Albert ----- he has been purchasing dozens of these and reselling them. No problems so far see my feedback. If too much voltage was applied they can be damaged. See Maxwell website for more info on the use of these.- cusdn"

poynt99,
When some of the poster here say "center tapped," they might be referring to their own lingo. Who knows. I have gadgets circuit running nicely in spice. So at least I know it oscillates. 


Gadget,
I don't see the big deal with people trying to get the details. You people are using unconventional descriptions. Maybe more people would replicate it if the drawing was clearer. Anyhow, I gather that my last drawing was correct?

Paul:

People have been giving and getting the details here for over 10,000 posts but, since you are not motivated enough to read back more than 5 pages, you don't get it.  WE all understand this terminology because it was all agreed upon back, you guessed it, in the previous pages.

Look at it this way...when the transistor was invented back at Bell Labs, and they decided to call it a transistor after all of their research efforts, someone later comes in and says "That's not a transistor...what is a transistor anyway?" it might not be received too well.  Especially if all of the research leading up to that point was published and readily available to all who choose to read it.

Okay I appreciate it Bill. So how many pages back in this thread should a person read? All 1000+ of them?

@Paul

I believe the first 150 pages or so , should be enough to get you up to speed.

After that is more elaborated version , and confirmation of concepts from the beginning pages .
