i'm trying to duplicate this simple JT circuit shown here::

http://www.instructables.com/id/Make-a-Joule-Thief/

but thus far have had no success lighting 1 LED with a single AA battery like is shown here.

theres just not enough power available.
is anyone else having this problem??
perhaps im just not equipped with the joule thief "talent"?

im not to the point of calling this a hoax,, but this is not working the way people say it should.

i have verified that the transistors are turning 'on', and passing power through them.  But the power im getting is exactly what the battery is putting out, nothing "thiefed" here....

you're going to call it a hoax? i can't believe you would even say that...
keep at it. persistence usually wins the day.

Its not a hoax They can be hard to get to work sometimes but I am lighting 140 LEDS from 1 AA and they are really bright. Can you post a pic of your JT so we can see whats up?

Thanks!

Looks nice. Did you get more than 450 volts with it?
