Does it have to be so big?  ..Can't you simply tune it down for testing purposes?

depend for what i want to use it for.
as you might guess, i won't use 1.5 volts on this one. 

i already have i bunch of smaller cores made with the same garden wire for testing.
3     2 inchs internal, 1 inch high, with 2, 3 and 4 layers width.  <<---opps edited
2     ~half inch internal, half inch high, with 2 and 4 layers.

those have been tested and work good with the right number of turns on the jt coils.

B.T.W.
i found out that a sheet of paper is not the best thing to use.
super glue will pass through the paper and glue the whole thing to the pipe.
use plastic to cover your pipes, book covering plastic work good.

gadget    relax im working on it ....  you know how damm hard it has been ...     egos are a pain ..... i know this first hand ...

i thought i would post this ... 

to help anyone i can out with this... 

i am able to light the jt lite ... and my leds on my mk3 windings.. both ways AND THE JT LIGHT STAYS LITT....  HUMMMMMM.... 

BUT I KNOW I GOT THEM RIGHT WHEN I ADD A SECOND LED AND THE JT LIGHT DOES NOT DIMMMM

WHEN I GET IT WRONG IT SINGGGGGS .... meaning i have  RESONANT TRANSFORMER ACTION ..... 

i do not want this yet ... altho WHEN BUILT PROPERLY ...   WE/YOU CAN MAKE EXECLENT USE OF THIS .....

GADGET KNOWS THIS .....



hence input will drop out put will increase both the resonant transformer action and the good stuff.....

ist!

@TheNOP,

The idea is that any oscillator has the potential to create radio waves.

@Jadaro2600 and electricme
you gave me an idea about eddy current tapping.

the core needs to be made of insulated wire .

   ..some work being done with magnetic paint.  Just an hour or so, And I'll be able to get some results.  This paint is very ferromagnetic.  ( dripped sideways and onto a magnet.  That other stuff I bought was crap, a big grey slug in the bottom of the can, and it didn't mix well at all )

This was dipped, I may brush the stuff on other tests, it seems it would waste less.
