@ stprue

My tests show only one electrode of neon lights with a solenoid pickup coil. My question was if the MK coil would light both electrodes of neon.

ahhhh very good question...I wonder...sense v or c  or both are going both ways...maybe!

ok jeanna i found A CRAPPY 1 INCH GOLD MINE...  all i can get is like 70 v i tryed everything

is it the coil 2 10 120

wich is now 2 2 100 30 ga ..
its a lousley core ...

Oh Darn!

I cannot get that medium to 'move' [oscillate the transistor] with so few turns as that. I usually need at least 4T of both to start it up. Even then I have not been impressed, but they (the toroids) probably know that.

I like the filter.
I just learned - by reading the included information -  - that the filter has 1.39mH per side. each side is wrapped with 19 turns.

I have always removed those coils, but this has given me all my best MK1 /MK2 results. 'course, I didn't get 450v on it yet... but that's another story.

  Now you are also a movie director and producer, cool.

The scope shows voltage when JT is on because JT is coupling to the coil. There does not have to be a direct physical connection for energy to flow from one place to another. Remember my one wire neon? Energy flowed from unconnected wire back to JT by capacitive coupling.

Great vid....  anyways nice vid and now I want to make one!!!

P.S.  You should really try this tap winding, it has so many options for hook up.

Thanks,
What are you calling a tap winding?
Did you go into detail on that? I thought I had read everything. Sometimes I miss a dozen posts when they come too fast.

Please describe, or say where you did.

Thanks.

@Wilby,

thank you

Thanks xee2,

So, that qualifies it for radiant when the coupling is in the air, right?
I guess we don't know too much, since tesla had studied this and so very little of his free energy radiant discoveries made the light of day.

Thanks, it was fun to have a surprise like that.
Not all the Stubblefield coils are as good as that little one. The 2 to follow will show that.

I added up the inductors, and only mentioned in passing that the stubblefield coil is one big inductor. ( with those 2 little ones that are a total enigma)
So
JT is 1 then 4 more on the board and then 3 more in the NS coil.
