Build the Lightning Bulb -  The Lightning Bulb circuit uses a quadrac (see Fig. 1)--a device that combines a triac and a diac trigger in a single package--to control the supplied current. Figure 1A shows the schematic symbol for the quadrac, while figure 1B shows the pinout for the unit used in our circuit. Note that quadracs are increasingly difficult to come by;….

Introduction to Tesla Coils-Postscript -  (electronic circuit added 10/06)
Solid-State Tesla Coil, #1 -  Nikola Tesla is considered by some to be the greatest inventor of our modern electrical age, and many experts consider him to be the true father of radio. However, today he is best.... [rewritten by Tony van Roon]
Solid-State Tesla Coil, #2 -  Tesla coils have been around for almost 100 years and, with th exception of vacuum-tube driven coils, not much has changed from the way Nikola Tesla invented them.  This article describes a new type of Tesla coil: a true solid-state Tesla coil..... [rewritten by Tony van Roon]
Square Tesla Coil -  Figure 1 shows the schematic diagram of the Tesla Coil circuit. The circuit consists of little more than a few coils, a step-up power transformer, and a capacitor. Power from an AC wall receptacle is fed to transformer T1 (a small neon-sign transformer) which steps the voltage up to about 3000-volts AC.…. [Tony van Roon's circuit]

Tesla Coil Circuit-Version 1 -  My first tesla coil, runs on a bug zapper transformer and produces one to two inch discharges. Page includes information on repairing the bug zapper transformer.  (circuit added 6/07)
Tesla Coil Circuit-Version 10-SSTC -  A medium power Solid State Tesla coil that produces about 9-inch long discharges.  (circuit added 6/07)
Tesla Coil Circuit-Version 11 -  An old-fashioned and large spark gap Tesla coil with a 6" diameter secondary and produces sparks about 3 feet long.  (circuit added 6/07)
Tesla Coil Circuit-Version 2 -  A modified Tesla Coil Circuit, Version 1 tesla coil that runs on one six-volt lantern battery and produces 1/2 inch discharges.  (circuit added 6/07)
Tesla Coil Circuit-Version 3 -  A tiny tesla coil that runs on a 1kV oscilloscope transformer and lights up a neon bulb for a plasma globe display.  (circuit added 6/07)
Tesla Coil Circuit-Version 4-VTTC -  My first VTTC, consists two tubes: a 5Y3 and a 6146, and generates brush-like discharges about a quarter inch long.  (circuit added 6/07)
Tesla Coil Circuit-Version 5 -  The first large Tesla coil I ever made, which stands about 5 feet tall and generates discharges about 2 to 2.5 feet long.  (circuit added 6/07)
Tesla Coil Circuit-Version 5.5 -  Same Tesla Coil Circuit, Version 5 with a smaller secondary.  (circuit added 6/07)
Tesla Coil Circuit-Version 6-VTTC -  A odd capacitor-less VTTC that uses a 4X150 and generates discharges about a half inch long.  (circuit added 6/07)
Tesla Coil Circuit-Version 7-VTTC -  A triple-807 powered VTTC that produces bright and powerful one-inch discharges from a massive 760V transformer.  This VTTC makes very interesting plasma globe displays.  (circuit added 6/07)
Tesla Coil Circuit-Version 8 -  A medium-sized 2-foot tall Tesla coil that produces about 1 foot long discharges.  (circuit added 6/07)
Tesla Coil Circuit-Version 9-SSTC -  A low power Solid State Tesla coil that produces about 6-inch long discharges.  (circuit added 6/07)
TESLA COIL DRIVER 1 Power Supply
 -  In this chapter, we deal with the design of the Tesla coil driver. We will discuss several components or subsystems, including the power supply, the controller, the gate driver and inverter, the fast fuse, and the current sense resistors....(added 07/08/09)
Tesla Coil/H Volt Generator (Aaron Cake) -  This is a fun and useful circuit for demonstrating high frequency high voltge. It can produce up to about 30KV, depending on the transformer used. It is cheap and easy to make, thanks to the standard TV flyback transformer used. It can power LASERS (although I have never tried), demonstrate St.Elmo's fire, and even cause a fluorescent bulb to light from as much as 2 feet away. 
Tesla Coils-Version 1 -  At first, I thought tesla coils were difficult to build, then I realized I could build a very simple tesla coil. I preferred a transformer from 1KV to 4KV to build a small tesla coil. I found a bug zapper transformer, which produces about 1KV to 2KV. It was used, old,....
Tesla Power Receiver -  ....
Triggered spark gap -  This is purely a construction article….(added 05/08)
