Joule Thief

@ jeanna .,
  you know from transistor to transistor they are different . you could buy 20 2n2222's and maybe one of them will run on .4 volts .some have better hfe  I have seen silicon transistors run as low as .420   volts even thought the specs say 5 or 6 .. I also have a few (very few )germaniums that will oscillate at .2 volts .. we keep those in a safe place ..just a little bit of info . i know you said you had a can 2n2222 and a plastic 2n2222 . same transistor just one works better .If they are not Mil specs then what we get on the open market is just good enuff  i guess and sometimes we get lucky  ! .

   it will with out the cap ...

ist!

Ist, When I was fooling around with the AAA fuji and I just couldn't get it to stay lit, I found that I needed to hit the bulb with the cap points then hold it with my hands. then it would stay lit.

Gadgetmall told us a little about his switch. Maybe we can get more details... eh GM?

I think you need 2 things going, one a steady stream for keeping it lit and the pop to get it started. I think you are right there.

Since these things are already made for 120 volts lets get them to work. You are sooo close!

I think it must be possible to light the cfl without gutting them.
Keep it coming.

Just wanted to add this to your thread might be an idea

Enjoy and check with your legal regulations...

It appears to me that the joule theif is nothing more then stealing power from the air using resonance LRC I dunno if this is correct but it is my assumption based on guess work and lots of reading.

@ Jeanna

Great posts   I love the "Circuit Assembly" on the Astable Mutivibrator link you just posted above.  I was thinking that it would be a great addition to this thread (and this forum) and help people understand the circuits being discussed.

Anyone proficient in Java script...

Regards to everyone.

jenna indeed verry nice link  you know it will get use my way lol 

but yes i have no trouble to light a cfl striped down form just an aa battery ...  no cap on out

but we want to START A CASCADE EFFECT    hence   aa powering cfl curcuit as it normally would from mains power ..... hummmmm

sure ...  it can easly be done .....  but i want to take the out put of the cfl driver ......  as step # 2 up the ladder .....  so

will the out of the cfl charge a cap ....... 

if so how much ...  how fast ....    bill you have some super caps think it will charge them ?   

ist!
