Joule Thief

How do you power a 2v led with a 1v power supply? With a joule thief of course. This circuit works similarly to a boost converter but with all passive components. I also reduced the inductance of the transformer because, one, less inductance means a smaller cheaper transformer in real life and, two, it increases the frequency to 50hz which is similar to the flicker of a light bulb and not noticeable to the human eye.

You may need to shake your phone to inject noise and get it started

Nice... thing is that coupling seems bit too high for such a transformer... And I don't want to be rude just ...can you come out with something new?
