Joule Thief

I have been trying to get caught up on this thread for a while, damn, it's friggin' huge!  For good reason too, this circuit is superb and a lot of fun to learn from!  Just wanted to pop in and share my latest replication of it.  I cant say it's free energy, but I can definitely say it's making me scratch my head and redo tests over and over...

Thanks to Pirate for peaking my interest in this circuit some time back!

@ Captainpecan:

Good to see you!  Nice video.  Welcome to our group of merry experimenters here.  Actually, you will see a few pages back that the Young Effect was being discussed in a positive manner.  These are good folks here.  Open minded, intelligent and very helpful.  I don't think any of us has reached the limits of what this circuit can do.  It is not magic by any means but, I still believe it is one of those overlooked things in science that has a place for further exploration.  The folks here are very sharp.  I am having a lot of trouble trying to keep up with them.

Hello captainpecan  and welcome .
             I Like your Video A+ .the Music almost gave me convulsions though Really Mind blowing when you got Vertigo    Can you Share what circuit you used and the size of your toroid and winding ? Thank you for discovering the cap effect . I have never seen it demonstrated in a better way than you did . Very out side the box thinker . We need your concepts here to further this project along . Lots more coming !!!

@ Jeanna

In the picture I recently posted you will see one side of the coil having a double crossover and the other side does not.  On your Mk1 do you have a single or double crossover winding?  Also Do you have any pic's on your set-up? I'm a big visual learner

@ jadaro2600

IWouldn't only partially opening the transistor CE path create resistance in the transistor and thus heat buildup?  Or am I thinking of a transistor acting more like a resistor and/or relay?

Like NOP said, the transistor is much like a variable resistor. But the resistance never goes all the way to zero. The amount of heat generated is current squared times the resistance. When the transistors resistance is high the current is low so not much heat is generated. When the resistance is low the current is high and the high current generates a lot of heat. Since the amount of heat generated is proportional to the square of the current, doubling the current produces twice as much more heat as doubling the resistance.
