Voltage doublers are an easy and inexpensive way to experiment with high voltage. If you've been looking for a way to generate high voltage, you've undoubtedly run across the voltage doubler. Voltage...

A climbing electric arc has held the imagination of science-fiction fans as the symbol for an eerie laboratory! In many sci-fi and horror flicks, especially the stock "Frankenstein" variety, along...

It's a high-voltage apparatus that has earned a place in history. Now it's your turn to get in on the fun! "Wimshurst machine? So that's what it's called!" my neighbor said, his eyes as wide as half...

Have hours of high-voltage fun when you experiment with this working high-voltage generator. The first known electrical generator was built in 1660 by the German experimenter, Otto von Guericke (also...

Build an updated version of Nikola Tesla's most-famous experiment. Nikola Tesla is considered by some to be the greatest inventor of our modern electrical age, and many experts consider him to be the...

Our solid-state Tesla coil can produce sparks as long as 8 inches with a peak output of about 100,000 volts. Tesla coils have been around for almost 100 years and, with the exception of vacuum-tube...

In addition to his many important contributions to electronics technology, Nikola Tesla gave us "lightning generators" that to this day fascinate and entertain. Nikola Tesla (1856-1943) was a...

A universal power source for an Eye-of-the-Storm-like display, and other unusual plasma and neon lighting devices. You no longer need to go to a local discotheque to see the latest in unusual lighting...

In the mind of the electrical genuis it's named for, it was a practical transmitter - but our version is strictly for thrills. Spectacular fireworks include a ring of fire scribed by wire pivoting on...

Miniature in size only, this physics classroom project packs 60,000 volts of power at 500,000 cycles per second. Yet it's safe! You can make spectacular demonstrations with this Tesla coil (Fig. 1)...
