I just tough of it if you make a single jt toroid the best way would be one coil of jt on halt of toroid and second on second half that would give you the possibility of going all the way around more than one time .

The tesla patent is a step down transformer but its said that the primary and secondary can be switch around for step up function, since the emf is usually in the minus range the secondary will see it as a plus spike.

the input of coil is the positive side and output the negative side, this plays a big role.

My best testing equipment is the brain , multimeter dose help

@ Jim:

I am impressed with your testing equipment and I believe it will come in handy before all this is over.  I do not have the ability to test such as you have.  I think we have some interesting things to look into here.  We all know that you can take a transformer and up the volts....this is well known.  What I don't get from my results is that an led takes about 300 mA's to light up.  (and around 3.5 vdc)  So, how can I get 400 leds to light up from a single AA battery?  Yes, we can up the 1.5 vdc to whatever we need.  But, what about the amps? (mA's?)  I have not done the math but I believe that there are more mA's needed to light 400 leds than are usually available in a AA battery.  What do you think?

you dont want to know what i think ..... lol 



i love the progress everyone is makeing 



you are transmitting ....  and you are recieving 

ist!!

@All

I made these changes from Jesus' schematic with the exception being that I'm using one LED instead of multiples. Before I added the diode and cap, I was getting 1.4vdc across the LED. Just adding the diode and cap, I am getting 3.0vdc and some change; all from a single AA battery.      Also, I am getting 115 mA with this as well. Just this simple change gave me more than double my original output. I am soooooooo going to try this out on my Earth battery this morning.
