I have a wide range of interests outside of amateur radio. Mainly involving science and technology, but also history.

High Voltage Experiments. Amongst other things I have built a number of pieces of high voltage apparatus, mainly Tesla Coils. Here are a few pictures of some of my high voltage stuff:

induction
Small educational induction coil.

geissler
Geissler discharge tube in operation.

maltese
Maltese cross tube circa 1930

maltese1
Maltese cross tube in operation at 10kV

deflection
Electron deflection tube circa 1930

Electron deflection tube in operation at 10kV

cap
Homebuilt 2n2F 25kV working voltage capacitor

mmc
EHT capacitor for Tesla coil use, consisting of 12 1.6kV 100nF pulse capacitors in series, with individual bleeder resistors. Total value equal to 8n3F at 19kV working voltage.

hv
10kV power supply based on a television flyback transformer (line output tranformer)

sst1
10kV power supply under test.

coil4
Mini Tesla coil, with a multiple spark-gap. For an indication of size the coil is approximately 125mm tall. It produces 125mm arcs (approximately 100,000 volts)

tc1ddischarge
My first Mini tesla coil, rather larger than the first one but producing a similar discharge. The multiple sparks are due to the length of exposure.

danger
Warning experimenting with apparatus like that above is dangerous. High voltage can kill, also the vacuum tubes shown are giving off low energy X-rays!
