Joule Thief

[synchro1]

My Honda Insight Hybrid lost it's main battery and  the charging system for the 12 volt. I'd like to try and keep the 12 volt charged while underway, as it's needed to run the ignition system. I wonder what the best Joule thief configuration would be for this job?

I looked at Mopozco's fast charger but he's charging to a same voltage battery. I would like to charge the 12 volt from a smaller voltage run battery if possible. Can anyone help me?

Hi All

Here is a pic of the camera circuits, I hope it shows up clear enough to see just how many variations there are with identical looking camera's especially the Kodaks, its no wonder I and probably a few others were getting confused with the camera mods that are posted somewhere on this thread.
The one I would like to have identified is cam 1, that one doesn't have any clear markings stamped on it to identify what it is, the primary transformer isn't like any of the others, this one seems to be laying down and maybe slightly larger, I'm thinking it may be a newer Fuji AA, as I have not seen a picture of this cam posted here. so any help would be appreciated.

Here is a pic of just the cam of interest.

that looks to be a older kodak.. the reuseable ones..
it should have a inverter transformer..  on it and a npn-pnp pair..
that model also had a 400v - 1 amp scr on it for the trigger coil..
inverter transformers only have 4 pins.. but they still work fairly well if you just use the same transistor setup..
but most i have played with won't lite a cfl on 1.5 volts.. it takes 3 volts or more..
hope that helps..

Thank you Kooler, you may be right, the transformer only has 4 pins.
Bummer, I was hoping it was a Fuji AA, One day I may get hold of one and be able to fire up a string on LED's.
Until then I will continue collecting used Cams.
