A Tesla coil easily makes it to the top spot on our list of “Mad Scientist” equipment we want for the lab, second only to maybe a Jacob’s Ladder. Even then, it’s kind of unfair advantage because you ...

Everyone interested in electronics should build at least one Tesla coil. But be careful. Sure, the high voltage can be dangerous, but the urge to build lots of coils is even worse. [Learnelectronics] ...

A few weeks ago, the design mag Dezeen reported on a lecture by the Danish architect Bjarke Ingels at the Royal Academy in London. During the lecture, Ingels nonchalantly described a plan to turn an ...

Electric current is often magic and mysterious. Before people knew about electricity, many natural phenomena appeared as supernatural events caused by angry gods. Fortunately people today know physics ...

The Tesla coil is a resonant transformer that generates AC electric fields that can power fluorescent lights and neon tubes, as well as produce high-voltage arcs. It is essentially structured as a ...

Calling all Tesla fans! Electrical engineer Greg Leyh and his team at the Lightning on Demand organization (LOD) in California are raising the funds necessary to build the world's largest twin Tesla ...

Picture a reclusive man, dripping sweat all night in a dark lab, illuminated only by crackling sparks that leap from enormous machines and cast a purple glow across his face. This is Nikola Tesla, the ...

To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit's typical components were ...

My fondest Tesla coil memories began as wee tod playing Command & Conquer: Red Alert. I would build chains of these things to fry every oncoming Russian infantry unit. Here’s a handy step-by-step ...
