ehm... isn't that a matter of the transformer ratio?
So if you're getting out 110V from a <1V input,
at what? 20mA?
So that's a 1x20=20mW ?
divided over 110 Volts would be  0.1818 mA ?

Now if that's correct, then if you were to take a 1W input
at 1V and 1A, then if the transformer ratio remains the same,
you should get out something like 9.09 mA ....

So what's so super about that, exactly?

Unless of course the ratio output:input is >1 and standard
transformer ratios are useless...

   A little late in the lineup but here. I was reading the part where some one
wanted two signals from the same torrid but 180 out of phase. I did this
very thing while playing with transmission lines.
   Simply wind two coils around the torrid as output but reverse to each other.
Then join the two start sides as the common. The other two will now be reverse
phased to the other in reference to the common.

Also one coil with a center tap will do the same.

listen

HAVE YOU BUILT THE MK2 YET! ?!?!?!?!?!?!?!?!?!   JUST WONDERING ........ and im not tooooooo  sure you have read the thred......

if you did HALF OF YOUR QUESTIONS WOULD BE ANSWERED......

lets say .... this    WHO CARES WHAT THE OUTPUT IS ...... lol

THE QUESTION IS MORE THIS     HOW MUCH OUT PUT DO YOU WANT ..............................

also i can make 1 coil with 110v or i literly could make 20 .... on the SAME RING ..... DONT MATTER TO ME .......   THE INPUT WILL BE THE SAME ....

the out put will be whatever 1 coil is x how many i put there      sheesh ....

NOW POP A CAP ON EACH OUTPUT .......................DUH .....

IST.......

love it.

@ All:

I had an idea so I am going to try it.  I started a topic...Joule Thief Circuit Diagrams,etc. here: http://www.overunity.com/index.php?topic=6942.0

This is a locked topic but it will eventually contain all of the circuit diagrams posted here for easier reference for folks.  i may add some photos as well.  this will be so anyone can look and find the schematic they are looking for without having to wade through all of our posts.  If I have a wrong diagram, or if you feel I have left some out, please tell me here, or im me and I will fix it.  It is going to take me some time to go back through all of our posts here and pull out the technical stuff, so please be patient.

I am doing this in the interest of providing fast access to all of the technical information we have built up over these past few months.  Also, please feel free to post here, or im me, with any additional stuff you think should be included.  Thanks again to everyone for making this topic so enjoyable and informative.

Bill                 PS  I had wanted to do something like this for the earth battery topic last year, but never got around to it.

My Gosh . I dont know how you are going to do that . . You have to go thru every post  ? I wish there was a way like on other fourms to list the attachment on a thread so you wount have all that work . well if you take the time to do all that then i will download them all and zip em and post in download section . ok  ? I wanted to do that but the thread got to be a Monster !! . I am Sick as a Dog . temp is 103 . I check with ya ll  l8r
