I think the space is the limit, and transformer will work at a given freq . I am working on making one with 22x4 turn coil to connect in parallel
instead of 48 turns , to reduce the volt and get the amps up charging faster the caps also easier to work with and better to feed back to the cap or the battery.

Thanks again, good work!

Edit ; those transformer are like the one you find pc power supply ,those are easy to find in all sizes, can be modified to spec.

@all

A year ago I was experimenting with solar panels and found this photo on one instructable from http://instructables.com
It has the electronics hidden inside that icebox and a lamp shinning over it that made it self runner. I could not replicate it though.

@ Jeanna

I will try to dig one out and post a photo tommorrow.

I think that this circuit will keep this LED this bright for several years. There is almost no drain on the batteries so they will last a long time.

I was going to ask about that today anyway. How can I get the amps up? I think that is one thing that will get my Earth Battery to work better with my JT.

Hi everybody,
I will try to reply to all the posts at once.

@xee2,
now what an interesting concept. I will pull the jt led out and see what happens.

7.8 microAmps? Then all the earth batteries can work...

Timmy - did you see that? wow.

I will try that today too. Those whites I have seem to never wear down enough to warrant a battery change. Maybe they can work on 7.8 uA. cool.

Thanks

@MK1
Maybe that is why I have had trouble identifying things in your pics. You don't use a led in the jt part of it?
Also the turning around part...
I will view the videos when Mac turns home on Tues next week barring any more floods.

Thank you.

@jesus,
What a find. Too bad you couldn't replicate it.
I think since the toroid materials can vary so widely, it is difficult to replicate many of these toroids.

but, maybe we can find some keys to the parts and so be able to design toroid circuits that others can easily replicate.

@Jim.
I noticed when I added a second secondary, that the thing died. I am wondering if you have had more success with your 20 tap toroid ?

Maybe it can zap some mice? 

Thanks everybody,
