Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

It rained all last night so I have nothing else to report.
So, I will add this pic.
I think you misunderstand what I bought.
I think it is just a wall wart. no adjustment is possible.
I had to break it to enter it, so to speak. 
But, maybe I misunderstand.
I will have another go at this when the threat of rain has passed.
I am thinking about the unthinkable and opening up a camera circuit to get at that transformer that has 2700 secondary turns.
The thrift store had 2 microwaves the other day. I didn't even look for the price.
Either of those might be able to do something with 45mv... but the camera transformer is sooo tiny.
Talk about feeling blind!

a pic. I stuck the innards back inside for this portrait.

Some are adjustable. Yours may have just been manufactured not using the center tap. Your 2400va toroidal transformer is a plus.

I think there is a short.
But there is no evidence of one except when I touch the wire sometimes I see a very very high spike.
I went out again this afternoon and I do not see enough amplification.

But, maybe it is not a short...
Could the frequency be getting in the way?
I bet it is.
I got a beautiful sine wave at 25kHz. like it makes me think there is a leak from a radio station, but without this transformer the lines are all jagged. And there is no clear wave at 25KHz today... sometimes there is.

Here is what I am thinking about this.
There is no free lunch, meaning I cannot go the the thrift store and find an easy way out, because everything is made to work at 60 hz.
A transformer is a double inductor in a way.
If I have any inductor on this that has too much mass, it will be too slow for any oscillation to happen.
So, I think I not only need to wind my own, but I need something that will be happy at very high frequencies, or it will do nothing.

What do you guys think about that?

thank you,

While it is raining why not measure the coil resistance of the transformer. You will want to use the coil with the most resistance for the high voltage output (that should be the original 110 volt input) and the coil with the lowest resistance for your low voltage input.
