Hi guys today I noticed that on my JT the neon lights half of it.It's giving high voltage DC. Is it possible to extract AC from JT maybe have to do secondary?
Thanks

Hi folks, nice proximity device pirate. Though I was wondering if anyone read my previous post about what to put on the ferrite toroids to prevent wire insulation scraping off, just wondering if there is a better solution than masking tape, although someone in other forum said some kind of spray on stuff, though not sure how effective spraying something on would be. Thanks.

Most of my coils  lately are what I call candy cane coils....I use  normal insulated wire for most of them because  the wire goes through
more abuse when winding them.
I have been thinking of  trying a good coat of spray paint on the toroids to even things out ......then maybe magnet  wire would be practical for my coils.

Hi folks, Hi resonanceman, thanks for your thoughts about coating the toroids. Though what I've found now and for anyone else making these things, is that electrical tape is pretty good when its stretched tight over the toroid so its thinner and it tends to stick better than masking tape and electrical tape sticks better to copper when used to wrap coil layers. I've wound 2 30 gauge layers already for my secondary, going to try and fit a third layer on it, though I think I made my coil threading rod with a little too much wire to start with, will see. As i said i hope to light a fluoro, anyone else light a fluoro with such a small ferrite toroid core like this, though i have no idea the permeability numbers as it came from a surplus shop.

@all
