[FARC] Voltage booster?

[Philip Karras]

Has anyone built one of these? I've been trying but have yet to get it working. It such a simple circuit I can't believe I can't get it working or figure out what I'm doing wrong!

See the Instructable called, "Making A Simple Joule Thief (made easy), by ASCAS" : (They call this circuit a "Joule Thief" because you seem the steal energy from a "dead" battery)
http://www.instructables.com/id/Making-A-Simple-Joule-Thief-made-easy/

Any ideas about how to get this to work would be appreciated.

I'm using a 3-Volt white LED, and green core from a dead CFL, and about 20 turns of double wire.

Another I've come across is the Supper Joule Thief, "Make a SUPER Joule Thief Light! by clevelandstorms" at
http://www.instructables.com/id/Make-a-SUPER-Joule-Thief-Light/

Perhaps I should give that one a try instead.
