Joule thiefs and earth batteries

Much of what follows is based on the work of others, including but not limited to pirate (on Utube) . I became interested in the concept of earth batteries and joule thief's a while back. Quite a bit of work has been done on using modified disposable cameras to make these little beasts, If you have no idea what I am talking about I strongly suggest that you  google "joule thief" and "earth batteries" this should rapidly get you up to speed.
   My first successful attempts used the Kodak disposable cameras, they did work but I never thought they were optimum. Disposable cameras it turns out vary considerably by brand and model, people seem to have tried many different ones and getting the correct info for mods on any particular model can be a daunting task.
 The Fuji disposables seem to be preferred BUT  even among these there are at least three basic types.
  After allot of experiments and destroyed camera circuits, I have decided that the Fuji cameras labeled "continuous flash" seem to be by far the best. what follows is the info that I have dissected from the available info, this should make making these a bit simpler for all those that would like to experiment with this concept.
  My next step is (aka pirate) to combine these continuous flash thiefs with simple earth batteries and supper caps stay tuned.
