The Master Of Magnetics "Steven Mark"

@Dave,
In line with your scope shot request: what are you using, pc & sound card, pc card & software combo? I have the Heathkit with only a screen and data outputs.

I also can't find the schem to the 8/16 trace scope add on. But I will keep looking. The circuit is pretty simple though.
8 channels are fed to a 74151 which are addressed with a 74193. That is clocked by a 555. the 193s are wired to a 7404 hex inverter(only 4 are used) then to a resistor ladder and out to the scope. Only works for ttl as 74 series.

Thanks, giantkiller.

@Dave,
maybe you can just drive the 2 x 12 Volts transformer with the same noise generator
and just see, if the 240 Volts output cancels all out ?
There might be still some output, when you use noise as the source and drive the core
with it into saturation,so the input should at least be 0.5 Watts or so...

Many thanks.

Stefan, Could you, please, explain more about the bold sentence ?
Thanks

Steven said it is like a antenna, think of it as a magnetic collector tricking part of the Earth's field into thinking it is part of the generated field and then collapsing through the windings with the origanal field.
The 1 on the left has clockwise innercoils and CCW outer, the center one has 6 sections instead of 4(romancing inertial force, the right 1 has all clockwize wraps with a longitudal wrap to check for output there. Check the pic with the large coil closely and the output wire position on the 6 inch coil and you will see why I did that.

Stephen your going to be mad at me, I down sized the pic with photo shop and then screwed up and posted the full sized one. I don't know how to delete it. I tried to swap it with edit and it was trying to add the right pic on top of it. I stopped before that happened. No use adding insult on top of injury. Could you please wipe it for me?

I see you used a higher gauge wire than Marco. I have used 16 gauge and believe that a signal generator output needs amplification to drive that much copper.
That is a good looking coil. Why don't you put it up as your avatar?

Merry Christmas to all.
