Tesla coil photos

Newest pics are at the top of this page. If you want to see and hear a tesla coil running, check out the AVI movies on the UK Winter 99 Teslathon page

I had a lot of trouble getting the exposure right due to the light source reflecting off the toroid, so I sprayed it black!

Sparks up to about 18"

A couple of old oscilloscope tubes lighting up on the coil.

Keep off the grass!

Spark discharges about 14" long

Corona streamers from a couple of knife blades.

The red hue is the result of using an incandescent lamp for illumination.
