MK1:

Thanks for the link on those trigger coils.  For $4.00 US to put in 300v and get out 10,000 is great!!!  The ones I have (from camera circuits) take in 300v and put out 4,000 only.  Just think of the fun we could have with 10,000 volts?????

Hi Gary,
First about the conical.
It is just a tricky thing to build, so I put it off.
Without any connection through the toroid there is just what you found.
But, if you connect the free wires the way I did, you get the amazing effect.
First you make a 6 turn secondary. It is not necessary to make it large, and it may be better even smaller than 6.
Then I am assuming you wound the cone with 2 wires all the way and then connect the end of one to the beginning of the other. Now, if you connect the top free wire from the cone to the end of the toroid secondary and measure the total thing, it is a ringing cone.

About these circuits.
I have been trying to make the perfect amount of turns in a secondary to light the LoA bulb, and with a TIP31 or TIP3055,  and about 110 turns around a tor-61 from allelectronics which is about .7 inch I get about 600 volts.
This is high and I reduced that to about 84 turns and got 400v.

It was after I made those and they were waiting for a AA battery holder, that you opened this thread.
Once you did that, I thought it might be better to make a high voltage toroid and put 3 in line and use a rheostat to modulate the brightness.
I can also change the base resistor, but at the moment, I will not change either of these circuits.
It is all a part of the experiment of course.
Have you seen Karl Palsness' video where he hangs one light in about the center, then puts another in various spots? The light in the middle always gets some amount dimmer.

From my other experiments earlier this year, I believe that it is possible to add a supporting inductor to each bulb, but that needs experimentation.

I agree with you.
Make a bunch and get the feeling for what to do when you want some effect.
That will inform all of us.

thank you,

I tried  all  the connections I could think of  with my conicals
I tried half a dozen coils .......I tried connecting the secondarys.......I even tried the primarys in series and in parallel 

I did  see that video
I have not looked into that kind of thing to know  for sure what is going on.....  very impressive though

I think the first Jeanna light  I will try will  be with a flyback JT core.
JTs  I have made from them before have been some of my strongest.

I do not have any large toroids  yet ........so I will see what I can do with  maybe  3   5 for $1 toroids   then  maybe 5

I also have some E cores  I have been meaning  to try out.

Thanks for the links

That sparkgap  tube is really cool


If  I understand   right .......on a different thread they are using  similar trigger coils  as  receiver and transmitter coils for wireless transmission

   A spark gap is a minny accelerator.  It has the plasma it should have the magnetic confinement which alot of folks are not getting because they are not placing the spark gap to respond to the magnetic field of the tank inductor.  This shortens the pulse and gets you into the proper frequency range to emit gamma radiation.  Gamma takes apart an atom like shooting a needle through a ballon.  Not to worry. The radioactive 1/2 life of nitrogen is measured in seconds.  Who needs uranium we got air.
