Preemptive Circuit diagram.  Blue is the optional component I'm testing, the rest above it is the voltage testing area.  Point out any flaws please.

Well, ...I lost 2 volts with the magnetic paint, so it's back to the drawing board.

Hi everyone,

Wow, this thread is like a fast paced novel. It even has some drama worked in!

I am happy to see that the missing members have shown up.

Also, welcome to all the newcomers!

I have a note I made to myself to make a MK2, 3, ...8. Also, to use my Stubblefield generator that I made for a battery input and see how it works as a jt.  (and of course the ground is beginning to warm up so an earth battery in place of the battery is in order too.)

I will be buying that hand held oscilloscope if it is still available, and some of the pots that are multiple turned. I need them for the tuning.and then... well, I am not too sure...

Oh, I want to share this dream fragment. I think that at this stage someone here will know what to do with it. I am still not, but I think the jt is where the dream applies.

It isn't really a dream, it is just a piece of downloaded info that says, make 3 coils on 3 axes. I think jadaro's coiled coil and twisted transformer are getting close to this 3 axes idea, so... for what it is worth, there it is.

I will wind something tomorrow. I need a nap already. I have been reading this thread for 7 hours and my eyes are too tired to make something today.

It is great to be back.

EDIT
I really love Nassim Haramein's work. I hope he doesn't mind.
I am adding this little pic to show what I mean. If you imagine the core toroid as jadaro has made it then look at the energy directions traveling around the toroid itself. I think that defines 2 axes, then add the spiral that travels through the center. It is on a third axis. A pic is worth 1,000 words:

@ jadaro2600

Point out any flaws please.

Not a flaw, but a reminder. When the LED is in the circuit it will limit the collector voltage to the LED forward voltage drop (usually about 3.5 volts), so any voltage changes due to the transformer will not be evident.

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

?
i don't see you point.
care to give me more details of what you have in mind ?

see this MIT lecture, you will find it quite interesting.
it will help you to understand why you have the results you had with the mag paint.

well, the whole 8.xx lectures are interesting.

the core needs to be made of insulated wire.

garden wire is insulated.
the way i done it is like an insulated coil, not far from a slotted toroid.
