Joule Thief

   Merv:
   I just saw your reply.   Thanks for your comments.
   I have seen most all videos on youtube concerning the Jt circuits, TPUs, etz...  so I am familiar with what has been done. And I've also been following these threads for years.     
  Mostly I am interested in what has not been done. Like lighting ones house using a Jt technology,  as in self running, self charging 12 volt Jt System that can light up a household with low voltage incandecent bulbs or warm whites Leds. The questions is, is it worth the extra work to accomplish it using the regular incandecent bulbs. Maybe it is a "Fools Errand" like Bill says... But CFLs and superbright cool white Leds are a very unpleasant lighting option for me, even if it were "free energy", but, possibly the warm white Leds will do.

Thanks for the positives comment . Now i have one affirmation to make ...

Working one the jt , i was never able to make a step down ration work always had more volts then 1.5 , now how do they make them ? The answer is to make a lousy circuit and parts ...

one of  my projects  deals with making low voltage  power  from a JT
I can't find  where I read it but I found a good explination  of how a  Grey tube works.
The  spark gap and the  metal plated used  as collectors  just  create impulses .......high  voltage impulses ( like from a JT )
These  impulses  are then fed into a special  transformer.
This  transformer  is  center tapped.........on the input  side  you input  the high  voltage  impulses.......IMPORTANT  on the input side there is to be little  or no current flow........Just alternating potential
The other side of the coil  outputs low voltage high  current POWER.
I am wondering  if driving an ignition  coil with a JT might work

I am currently  working on a compact  JT  that does not need  an expensive or hard to find  toroid  and can at least light  a CFL

I will then work on modifying  a similar  coil  for my center tapped  Grey transformer.

It is a  good challange  to  light a normal bulb .......but I agree with Bill........ LEDs are the way to go .........MUCH more efficient.
I know Jeanna likes the warm yellowish  light too.........she  adds a few yellow  LEDs into the lights she makes.

Pirate, thanks for starting such a great thread, unfortunately in the last 2 weeks I've only got to page 79 
So I'll catch up with you all..... sometime next year
