Joule Thief : It Last





Introduction: Joule Thief : It Last

I'm beginner in Electonic, tried things as hobby.. a basic circuits. I  tried Joule Thief circuits  but wasn't success. Searched webs and testing every valuable comments in this instructable... still it's not worked.

Joule thief is not working.

Then I found this site. • View topic - Joule Thief Kit

The Notice in  Schematic caught my attention. Checked mine and corrected it.

For the beginner... the tricks and notices are VERY IMPORTANT..., success in easy Project is a base to another difficult one. I should have commented in the above instructable topics but decided it should be raised for beginner  easily searching.
Thanks for those above 2 web topics for my success. :)
Sorry for all the Pro here you could pass it. This is my first submit so please be easy to me.

Here is what's wrong and corrected on my project.

    Well done! I made the same mistake and a fellow ham radio friend pointed it out to me, dah. Then I went searching and found the explanation, I believe on Wiki of the two types of windings, if you attach the same side ends of the wires together it is called a non-inductance winding, and it is useless for the Joule Thief. I haven't yet found out what it would be good for.

    I want to make one and was going to check out the pic you have up there but it's extremely blurry.

    Thank you for posting this. Exactly what I needed, got my failed project working now. :)
