Tesla Coil Built From Trash

Greg Miller prides himself on his dumpster-diving ability. To encourage others to take up the terrestrial sport he developed this Tesla coil built entirely from trash (Coral cache link). The power supply is from a neon sign he found behind a frat house. The capacitor bank is constructed from high voltage caps found in televisions. The spark gap is a pair of 1/4 inch bolts. The primary coil  is formed on a lamp shade using a cord from a humidifier. The secondary coil is made from the wire of a microwave fan and a cardboard tube. The toroid, pictured above, is constructed from two stove eyes. The chokes are wire wrapped around ballpoint pens. He’s got some nice pictures of it in action plus a guide to what goodies you should salvage from consumer electronics.
