Tesla Down Under

A Tesla coil is device to develop very high voltages pioneered by Nicola Tesla over 100 years ago. In its simplest form it is an air cored transformer driven by discharging a high voltage capacitor through a few of the primary turns. This sets up a high frequency resonance in the secondary coil. This resonance occurs between the inductance of the coil and the capacitance of a rounded metal object (typically a donut shaped toroid) and a very high voltage results in streamers directly into the air or sparks to nearby objects. The upshot of this is an amazing display of lightning bolts streaming from the equipment. Peter Terren from Perth is a 40-something year old, 1st year university physics dropout who builds Tesla coil and other high voltage toys in his spare time – check out his site at http://tesladownunder.com/index.html
