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 ...

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 ...

The folks who successfully crowdfunded a DIY singing Tesla coil kit last year have taken to Kickstarter again to bring a smaller version into production. Like its older and bigger brother, the ...

This Tesla coil resonates in the 41KHz range, and is further modulated so the sparks actually create music. A square wave (perfect for 8 bit music) is fed to the circuit to control the pitch. The ...

DIY hacking has given us some great things -- a Raspberry Pi turned mini Super Nintendo, a Kinect sensor turned 3D archaeological scanner. But now, US basement hacker Rob Flickenger has given us ...

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 ...

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 ...

It’s badgelife season, and if you need an idea for a killer piece of wearable electronics, look no further than this PCB Tesla coil. Yes, it’s killer, doubly so if you’re wearing a pacemaker. This ...
