Single AA battery to light WHITE LED for long-long time

[nul-points]

hmmmm - don't think you intended your correction to short out the bifilar windings on TO2?

this friend of yours with the 'OU' circuit isn't called Randi by any chance?

wow, 2 hours pass (battery still not drain)...
most efficient !  (my last achievement, drain 0.01 volt every 1 hours)

Wow my battery drain again

Here is result with T02 only 60 turns bifillar + 90 turns 3rd.

Time          Volt
10.15        1.248
13.17        1.247
16.21        1.246

Average : drain 0.001 every 3 hours ......amazing!
Measurement at + battery : 13 mA

On my calculation , if I start from 1.299 volt  to 0.500 volt , drain 0.001 volt every 3 hours its mean
  1.299 - 0.500 = 799 * 180 minutes = 143820 minutes
  143820 minutes / 60 minutes = 2397 hours = 2397/24 days = 99.875 days (more than 3 months)

Wow great, most efficient i've got.

My question is, 13 mA * 2397 hours = 31161 mAH    , more than my capacity battery ?

I got my stock wire/coil, tonight i'll make T02 as my friends said.

Maybe you guys can help me..
I make led hula hoops for my GF and her friends.. Right now i am powering them with 4 rechargeable AA batteries.
I am trying to make them cheaper for everyone..
I would like to make them powered by a single AA or 2 AA rechargeables with a drop in style battery holder.. Would i be able to use a circuit like this to power 21 LED's?

Here is my site with instructions how i make them right now.. any info would be greatly appreciated..

Please email me with any suggestions or ideas, i am always looking for new ideas.

Go and check out my joule thief topic here: http://www.overunity.com/index.php?topic=6123.0;topicseen

I have been able to light up to 400 leds from a single AA battery.  we have many circuits listed there that will do exactly what you are looking for.  I know it is a very long topic, but you can skim around and find exactly what you need.  If not, post there and ask, the folks there are very helpful.
