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.

awesome thanks.. Ill take a look.
I am new to building circuits.. is there a palce that i can buy wht i need pre-made?

Or maybe someone can just tell me what i need to do to power 21 LED 3.6V / 30ma   with 1 AA rechargeable.
How long it will last for?

dog:

Just introduce yourself on the topic there and tell folks what you are trying to do.  Then, go back and read as much of the topic as you can because it is all there. (someone will probably suggest this)  These are very simple circuits and just about anyone can replicate them.  Also, you can check out my youtube joule thief videos if you want.  Many others have them as well.  Some are very basic and simple and some are very advanced.  Just search youtube for my channel: Pirate88179.  I look forward to seeing you on our topic.

@ dog812

Check out a user named gadgetmall in the above thread that Pirate pointed you to, he has units for sale that will run a long time on 1 AA battery, he has his site in his signature, it's: www.sunpowerwindpower.com.

@ Dog:

Goat is correct.  I forgot that Gadgetmall had units for sale.  He really has some great stuff that he has developed and he is a really good guy.  If you want cheap light that last a really, really long time, the joule thief topic is the place to be.

hello sir how r u?
i am really impressed with youre interest and efforts for designing a very very eficient jt..or an overunity one...
sir i hava a small request from you do you know a samll 1.5v joule thief circuit which will run a white led brightely for more than 150 hrs?? or maybe 100 hrs???
ive been looking on this site for 4 days now but there ret many circuits and i am not sure which one is the most efficient.....sir,do u have the circuit of GadgetMall Joule Thief some 1 told me that its very very efficient and uses only 1 mili amp...
kindly please send me GadgetMall Joule Thief circuit if you have it or any other which according to you is useful for me...
thanks

I would recomend looking at the diagrams section on that topic.  You should try to build a very simple JT first and work your way up to some recent ones.  You will have a better understaing of how they work so you can come up with your own designs..  Who know maybe your design with be the most efficient ;)
