Hi Guys,
I thought I would make one of these so called slayer exciters.
It’s a tesla coil apparatus, but technically speaking, it’s not because the driver is low power,
and a capacitor formed to earth by the secondary is required as part of it’s oscillator.

That was fun, but gets boring quickly, so I’m currently having a go at selectively lighting
tuned to resonance receivers like this one:Image Link
It is tuned to resonance of the coil so the LED can be lit from further away,
and it is also selective of the supply coil’s frequency.

I’ll have sampled, and will have to generate the resonant frequency myself so it can be slightly adjusted.
Cheers, Brek.

Warning: Completed unit is so sexy you’ll want to lick it Image Link

Hi Guys
I thought I’d have followed this up, but I have a slightly larger coil now, but still a desktop size.
The second one has a driver with transistor sockets so I can push it until one pops if desired.

Apart from plasma audio modulation which is a common development,
The most interesting experiment, at least to me was lighting a commercial neon brightly and wirelessly with a 12 Volt supply.
Now this makes me believe a better method to power commercial neons would be with a power supply and wireless coupling sleeved directly around the part of the end of the tube that turns back on itself,
or a wireless coupling built into the backboard (but difficult to shield).

This, at first, seems like it would be efficient only if you naturally had a high current low voltage supply.
From mains it requires a 12 Volt supply plugged into mains, then another supply for 3kV
or so in close proximity to the neon.
But I believe 50Hz is not the ideal frequency to drive a neon, and efficiency may be gained
by being able to move that frequency to anywhere within reason.
