Default Re: Wireless Self-Resonance Experiments

I wound a loose-coupled primary from brake-pipe and I feed it from an old neon mast-lighting transformer via an R-C filter, and resonate the primary with three 15kV ceramic capacitors ganged up and equating to about 4nF. I put a short clip on YouTube here.
The orange is just a little bit more capacity for fine tuning.
Impressive stuff. I remember my physics tutor at school set up a tesla coil experiment and he made the mistake of having the on/off switch quite close to the coil itself. Although he had performed this experiment loads of times before like this the arcs were really long and severe on this occasion. I'm not sure if this was a humidity thing or not but it was very funny watching him try to turn it off without getting zapped. He ended up getting zapped several times and we began to doubt his claim that the arcs were painless. He definitely wasn't enjoying himself on that demo...
