An Australian site detailing my various high voltage and other projects such as...


(click to enlarge)

STOP PRESS  This is my old site last updated June 2005.  Enjoy the pics here but it is best to shift direct to the new and larger site. Looks the same but a huge amount of new stuff and regularly updated.

CLICK HERE to go to tesladownunder.com

Tesla coil (above) with 7 foot sparks .  Awesome to be near. For more photos of sparks up to 8 feet (around half a million volts) go to Tesla coil sparks.

plus... A 1500 joule 800 volt capacitor bank with electronic switching to control peak currents of thousands of amps mostly to make big bangs but also to drive projectile devices such as a rail gun and coil gun.  Other  HV stuff stuff includes voltage multipliers, Van de Graaff generator, Jacobs ladder, lifters and other high voltage supplies. Various lasers inc NdYAG, HeNe and CO2Can crushing using a discharge from a pulse capacitor.  Magnetohydrodynamic drive, 800 A spotwelder.  Also miscellaneous electronic projects and a few half baked ideas...

    May 2005.  Vacuum tube Tesla coil, Strange HV/water effects.  Upgraded can crusher now tears the can in two. Nice video too. How to measure a 15,000 A pulse.  A neat use for microwave ovens as a high voltage supply.  Syd Klinge's 100KVA coil visits Australia.  For something different, my prize winning pen display.

Above, some unusual solid state Tesla coils on the left using SIDAC's instead of a spark gap, centre using a Royer circuit and on the right a vacuum tube based coil .

Above, from left to right: an electronic art piece, homemade computer plotter and a solar model car.

Above on the left is my new lifter with neon lights installed.  Center shows a run outdoors and the right shows the installation in a science museum.

Above left is my magnetic levitation display running, centre is hydrogen/chlorine ignition at the back of my model boat with magnetohydrodynamic drive and right is the bizarre ferrofluid.

On the left above is my home made Nitrogen laser  with the beam in Fluorescein.  The center picture shows the Nitrogen laser diffraction pattern.  The laser is ultraviolet but shines up with a blue fluorescence on white paper.  The right picture shows green 5 mW diode and red HeNe 10 mW beams grazing the camera.

Above left shows the 800 amp spotwelder flash. Centre is the flyback supply.  To the right is the completed railgun.

Above. Can crushing with magnetic induction upgraded and now tears the can apart with 40,000 A.

Above, the technical stuff about measuring the very high current pulses. On the right is a coin shrinking attempt.

Above, rewiring a microwave oven into a useful HV supply. Voltmeter to measure 60 kV +. Power supply 1971 style.

Above, strange behavior of high voltage. Woodburn fractals, the arc-repellant screwdriver and plasma in a magnetic field.

More strange behavior of high voltage. Electrostatic levitation of non conductive (deionised) water and arcs onto a water surface.

One volt can be impressive too (at 533 amps). Spinthariscope made from around the house materials to view alpha particle activity.  Internals of a 120 kV x-ray head.

Above, meet some visitors to our rural property.

Big Day Out with Syd Klinge's 100KVA coil in Australia.

This is a rather technical site. The glossary may help in the Misc page.

Disclaimer:
This is dangerous stuff. Your first touch of live primary Tesla coil voltage (8,000 volts) has a good chance of being fatal depending on circuit paths and peak current. The secondary voltage (500,000 volts) is less dangerous due to lower currents but will still cause burns with less pain than low frequency current.  High voltage capacitors as used with the coilgun and can crusher also have a potentially lethal charge.
The Dept of Energy Safety has approved the Tesla coil equipment but see
Misc for details as they are not plugged directly into the mains but rather pass through a 50 V AC stage. 
Read and enjoy the information here.  Do not attempt any of this unless you have read everything you can about it here and elsewhere and you have a clear and fool proof plan for safety.  See further info in

Want a display? I now have 3 running displays in 'science museums' in Western Australia. I am happy to provide advice, contribute to, or construct displays relevant to my areas of expertise for local use. By their nature many displays need ongoing servicing so local WA is probably the only feasible area.  Costs are reasonable and open to discussion.  This is not my day job so it helps if it gets my interest and has a challenge.
