Joule Thief

Robbie:

I just got notice of that in my e-mail and I was going to post it here as well.

Here are the details....I paid about twice that for my 650F cap!  This is a great deal everyone.

Bill

PS  Robbie, this is exactly the right place for this link.  Thanks.

Bill,

I'd like to know what Jeanna thinks,

What I would like to know from you.. is if you think your core is covered in the following book.

OK.  It says metallic and ceramic.  I have never seen that term used for the ceramic materials before.  This is something new to me.  I will look into this more when I get a chance.  As in my earlier post, the ceramic version, ferrite, is paramagnetic in that it does not hold a residual magnetic field like the metals do which is why it is so good for back emf and other uses.  You can put a strong neo on ferrite for months and it will not retain the field after the neo is removed.  As you know, do that with iron, etc. it will become magnetized.

***EDIT***  Here is a link to a video showing that an air core has higher output than other cores tested:

Pirate,

Thank you.

The point is that ...

    Without a 'good' Ferromagnetic Core
                 (utilizing the Magnetic Field produced by the infinite current of trillions of electrons)
                                                                                                                   an impressive Joule Thief won't work.

I believe you now agree.

No, I do not agree.  Not at all.  did you not see the aircore video link I posted?  Folks are lighting cfl's from aircores for many, many hours....no ferromagnetic anything.

The link I posted showed that the aircore had a higher output than ferrite, or iron, or any other core tested.

Did you not see this?

may you please specify what an "impressive" Joule Thief is ?(under your point of view)
I have read very attentively your assertions at the Tseung thread, and try to learn as much as I can (from you as well as from all others). My experiments with joule thiefs are oriented in the properties of air cores in which no ferromagnetic domains involved.
