Joule Thief

[jadaro2600]

quick question: ..when the magnetic field collapses, does it collapse with polarity in the opposite direction?

Can  you restate  your question ?

I would  restate your current  question something  like this 

Please  state in 25 words or less  everything  that has  been gained in the  900 +  pages of  this  thread . 

Of course  how  I  restated your question in a  somewhat exaggerated  manor   

Can you  be a little more specific  about what you are asking about ?
A summery  of the entire thread is just not practical .

@all
just poking my nose in like IST, lol

You are all a great bunch of people, I'm having fun fun fun also.

I havent forgot about my huge iron JT ring, its still blank, gotta change that
For those who dont know what I been up to the last few months, I been getting 60 odd volts out of my 83 earth batteries in series.
I have reconnected them into 4 banks, series parallel.
They dont wanna wear out,      I drivin a single white LED 24 x 7 over the last month at uAmps.
Isnt it strange what mucking in dirt n water does to one lol

Next stage is 1 Iodine drop in each cell, just to see what occurs

hooroo all

@ guruji

Is it possible to run joule thief with no batteries caps only?
Thanks

Bills right on the money, use a supercap, charge up the super cap first, then run the joule thief off that.
If you use a ordinary electrolytic it will discharge all its power as a single pulce and might fry the trannie.

something i been playing with...
it makes lot of high power sparks of course and will light small lite bulbs of 110v - 220v
it will blow a neon out with a bang...lol
the inductor help feed the emf back to the cap and speed recharging
i posting here cause i used the jt circuit on the tranformer like the camera rigs
warning if you try to build this...
don't touch the output. like me,.,. it hurt... hahaha

Nice circuit



What is the size of   L2?
What is L2 for?
It is  fed by a bridge ........the  output  of the bridge would  be pulsing  DC but more pure DC than pulsed DC
Will  your circuit  work  without  L2 ?
