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 ...

Who doesn’t want their own Tesla coil? Particularly if you can get one that isn’t incredibly dangerous or expensive to build. Well, this electrical savant built one in the 8th grade using vacuum tubes ...

Carbon nanotubes have gotten fanfare for rebooting Moore's Law and possibly powering the next generation of space probes, but that's not all the versatile material can do. How about shocking nanotubes ...

Like so many of the projects we feature, this one started with a cheap eBay module purchase. In this case, it was a little Tesla coil that made decent sized arcs but wasn’t quite good enough. The ...

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 ...

Tesla coils are totally insane, yet undeniably captivating. And they can be used for many things, from electric painting to dueling musical battles. But one trigger happy fellow has a different use ...

Using a powerful electric force emitted by a Tesla coil, scientists at Rice University have made carbon nanotubes self-assemble to form a circuit linking two LEDs and then used the energy from that ...

This “pancake” inductor wound with copper tubing forms the primary of the Tesla coil. The heavy black wire connects to an adjustable “tap” that allows tuning of the primary circuit. The elevated ...
