Trespasser said:Battery, switch and inverter all correct.
So that's it? No one has any idea?

That would be my guess as well. The foil-covered ball does somewhatTrespasser Inscribed thus:
Well its a high voltage generator used for generating a corona discharge
from the silver ball !
That would be my guess as well. The foil-covered ball does somewhat
resemble the business-end of a Van de Graff generator. Prolly like
one of those hippy-dippy things you used to be able to buy back in the
70's ('cos, like, man, negative ions are GOOD for you, y'know, man?)
But without knowing what's on the cct board (in between the xfrmr and
the ball) it's difficult to say for sure.

Wow man, Wow...
I agree ! I suspect that the large transformer just supplies a lowish
voltage, say 50v rectified to feed a neon relaxation oscillator feeding
a coil. A bit like a Kettering ignition system. The big silver ball
providing a load and producing a corona discharge.
Hi Jasen, Baron and Pete,
The consensus appears to be that the device in the picture is a small Tesla
coil. Correct is that induction coil triggering occurs with neon ignition. I
think most Tesla coils use a spark gap here. The spark gap in the image is
mounted instead across the induction coil output. I'm interested in electric
field emissions, and the spark's step function provides an 'all frequencies'
impulse. The shiny polystyrene ball has a strange dual function. Like the
high voltage plate capacitor which it replaced, it stores charge and
increases spark current. Unlike the plate capactitor, it somehow yields a
stronger electric field.
I suppose its quite like a miniature Tesla coil, and you were all very
clever in getting to that point. The minor differences relate only to the
pulsed, as opposed to continuous, high voltage supply. That would have been
difficult to determine from any image. Both devices are electric field
generators.
Well done.
