The Dummy toroid is so good i had to make a drawing !

I can put a heavy load on the dummy pickup coil without losing the high voltage on the regular secondary or changing the freq !

So one could light a neon or cfl while charging ! the circuit dose not consume more energy !

That is awesome work Mk1!!!!

1 Farad Wont do what he want to do . I have  several 10 farads and they wont run a jt a day .

that is exactly why it is good to test for OU.
you don't have to wait weeks to find if you have or not.

to use them as a source is not the same thing.

Quick question how log does it take to charge one of those monsters I might buy one payday! Will it charge from a JT? have you tried charging it from 1 aa?

-Altrez

I have not . Here is what i have done . I have charged it close to full capacity with 7 hours of sun with one tiny cis 5 volt panel . I am running test with it on an earth batteyr and it charges to a bit over one volt and runs a Jt with two 200k leds on it . across the two leds i read over 2.8 volts . I have charged it almost instantly with a 50 amp battery charger in about 30 seconds . The battery charger leads get Fire hot like a dead short and the voltage must be monitored if you do this so you don't go over the 2.7 volts . . I have not tried an aa battery yet . Closest thing is the earthbattery with its meager milliamps still charges it over a day . Probably faster without the jt load . BTW i have a special hook up and the jt is not directly connected to the charging EB but is connected to an identical EB inches from the original Eb RODS  ) There is a Slight enuff resistance even in dry ground that allows the cap voltage to bleed over a bit to brighten up the jt which runs on the eb alone . Kind of complicated and just experimenting with a different setup every week  and noting the effects . . I do have a circuit which shuts off the Jt in the day and boosts the charge  . here it is . I made it a bit better and the jt specs are not included but any jt will work . I have posted this before but made a slight modification . this Should run forever if the tiny solar panel is sealed up . Meaning out live Us .. I am working on a kool little circuit that switches out two sets of batteries without using a PIC programmer . When I have it completed and tested i will post it .

Edit altrez can you light one led and on neon at the same time ?

Hey Mark . I see your hard at it . NICE DUMMY

That sure looks like the 2 tier to me. you are taking one wire from the dummy "primary" and one wire from the dummy "secondary"
Yes?
Yippie!

And, can you juggle 5 balls and balance a dish on your nose?
OK so, tomorrow, I will see how far I can push those wires.

I suppose you put some diodes on that before it went to the battery to charge.

Would somebody please describe to me exactly which way to put the diodes? OR is it a diode bridge that goes to charge the battery?


Way to go MK1

thank you so much,
