Part 2 – No steel – Battery as the core
See this video: http://www.youtube.com/watch?v=-WFBi16MuqY
Whether it’s just the casing of this battery that i’m using that does it, but the Joule Thief is now running with no steel beneath the coils !
I must be missing something lol
Anyway, the battery is a 1.2V Ni-MH of 350mAh, from a standard solar garden light.
