    DIY 3V step-up “Joule Thief”

    There is an interesting tutorial for how to make 3V step-up circuit by using simple component from. The project is called Joule Thief. With this module, you can light up LED (it needs 3V) with single AAA battery (1.5V).

    Schematic for Joule Thief

    Review

    I have tried their tutorial, and it works wonderfully! Unfortunately I did not really take step-by-step pictures.. It is quite amazing that you can light LED with single AAA battery. I wonder how much current it can pull also.
    Next step is to implement fabric embed-able version…. will be coming up soon.

      This is really, really cool =D. Step-up seems to be a lot useful for battery powered projects. I am interested on it. Cheers!
