"The Miniature Lightning Box" is made from the insides of a
compact fluorescent light bulb (CFL) and an old TV flyback
transformer. The circuit inside of the CFL can generate high
frequency currents that are fed into a high frequency
transformer inside the base of the bulb. The high frequency
transformer boosts the voltage so the fluorescent bulb can light
up. The TV transformer makes high voltage and high frequency
current to generate enough electricity to trace the electron
beam that lights up the screen. When you take the CFL's
transformer and replace the fluorescent bulb for the TV
transformer, you can create well over 1,000 volts! this is my
version of a high voltage supply/Jacob's Ladder. I love this
project because the spring animates along with the electricity.
