@all

A picture of my latest tp coil , running at 90 volts and lighting 24 led in parallel

camera set to movie mode no flash , overhead light 80 watt incandescent.

It is running nicely .

Edit i had to show off my latest non energy related project.

Well xee2,
Here is what happened.
I added a second 105 cap.
I first just used one diode then added a second. I saw no difference but I may have seen a difference by the addition of the second cap today.

There is a difference with the direction of the placement with respect to the different secondary wires. The wire that shows the upspike on the probe of the scope must be connected to the cap side [3] of the arrangement.

Still nothing from the filament or the unmodified cfl.
However,
Using the neon and the unmodified cfl:
The attachment from the outside end of the diodes[1]  to the outside end of the caps [3] is much stronger than from the inside of the diodes [2] to the outside of the caps [3].
I added numbers to your drawing.

The neon glows one carbon rod very bright when connected [1],[3], and when placed [2],[3] the space between the carbon rods glows . This is the same look the neon has when only one wire is touching either secondary.

The cfl glows superbright when the connection points are [1],[3], and, not at all on at the connection points [2],[3].

I believe this shows that I am still not using the right size caps and or diodes for this to work.
What frequency is working for you with these caps sizes?

Thank you,

jeanna

oops forgot drawing!

MK:

Nice job!  I also like the practice amp as well.

Have you, or anyone else, tried slipping a core into the mix with your TP device?  I saw what Lidmotor was able to do when he introduced a core into his air core coil for his Dr. Stiffler replications and it really perked up the circuit.  Maybe a block or rod of ferrite might work?  Just to see what happens.

Nice going.

whats the amp draw and volts in
just wondering.. seeing if it pulls like my aircoil

good job

1.36v at .33 amps my meter fuse is broken and only seems to works on the 10 amps setting.

But it would need to be run at 1khz square wave , i am considering making a square wave generator from an op amp at 9 v then run that in a tda2003 i have here 10watt amp then try to pulse that strange thing...

the more you put wires on the primary side the more you get out of the secondary , its the reverse of regular logic.

But it doesn't really high amps , but high voltage would be great.
