I think what you are trying to do is good in running a CFL and to charge the battery at the same time, but the problem will be to allow the CFL to put out sufficant brightness and have enough power avaliable to charge the battery.

You could have the CFL switching on and off so fast that it wouldn't be noticed by the eyes (saves power also) and when the transformer turns off capture the EMP and feed it back to the battery.

First of all, you would notice the CFL will work longer, then refineing the circuit should bring success, the goal being making it to work all the time.

Reading the last 2 pages of postings has been jogging my memory where some people managed to recharge a battery while running a small electric motor, they modified the armature winding contacts (snapped off the contact tag where the wire was soldered to the copper segment) so at every 3rd pole there was a small spark which automatically sent energy back into the battery. During this moment in time there was no current being drawn out of the battery and momentum carried the armature to the next segment so it was being kicked at every revolution, which is frequency.
Th faster the armature rotates per second, the more energy is avaliable, eventually there is more energy to charge the battery so it all keeps running.

You could do the same thing by using a 555 IC as a vibrator to switch two seperate transistors, either on to off in a flip flop fashion, let the CFL be switched on by TR1, when TR1 is off, harvest the BEMF from the transformer through TR2 to the battery.

Gary's idea of a ringer circuit should work as well.

I could be wrong here, but I think John Bedini drew up a circuit where one part of the circuit needed to be off or the battery couldn't be charged.

You mentioning here about only charging the battery by touching the battery with the diode working a split second has got me thinking about it all.

Jim:

I like your idea of the pulses.  To me, pulses are always good.  I was just reading on another topic of the high dielectric strength of water and had maybe a crazy idea?  What if I were to take some of my clear plastic tubing and form it into a ring, fill it with water, and seal it?  And then, yes you guessed it, wind it as a toroid?  A water filled toroid.  At first glance, one might think that water would not have any magnetic properties but then, neither does air and folks use air cores all of the time.  One might even try filing it up with a ferro-fluid just to see what happens.

I don't know....just thinking out loud over here.  When I get a chance, I will give it a go.  If it works, then anyone, anywhere could make their own toroids and even vary the properties easily.

I think this is a excellent idea because ferro-fluids  material is composed also of oil , since oil and water don't mix the ferro fluid should react like a super fluid .

As long as the water is not ice , air should also be removed .

Btw , nice to see you all here .

You are still surviving down there in the land of Oz , Electric Jim .

You are right!

I dont know how to make the cfl to switch faster with the original circuit.

Reading the last 2 pages of postings has been jogging my memory where some people managed to recharge a battery while running a small electric motor, they modified the armature winding contacts (snapped off the contact tag where the wire was soldered to the copper segment) so at every 3rd pole there was a small spark which automatically sent energy back into the battery.

Th faster the armature rotates per second, the more energy is avaliable, eventually there is more energy to charge the battery so it all keeps running.

I also read about that a few years back but have not implemented it.

You could do the same thing by using a 555 IC as a vibrator to switch two seperate transistors, either on to off in a flip flop fashion, let the CFL be switched on by TR1, when TR1 is off, harvest the BEMF from the transformer through TR2 to the battery.

Can you post a schematic?

I will find the circuit that converts 1.5v to 12v and post it here, pointing out where the sudden connection circuit is needed. (a switcher that connects the diode output for a fraction of a second once in a while).
