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 ...

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 ...

Inspired by Wattson from Apex Legends, we brought the Tesla Coil concept to life—sparks, arcs, and all. This real-world turret experiment shows just how wild science can get when gaming meets high ...

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 ...

An oversized Tesla coil is a movie and a photograph which are blowing out lightning violently. The Tesla coil is also big, so the lightning is also getting thick. If you are doing such experiments in ...

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 ...

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 ...

Electric bikes, and really all electric vehicles, have one major downside: the weight and cost of batteries. Even with lithium, battery packs for ebikes can easily weigh more than the bike itself and ...

Easy Tesla Coil project features a wireless transmission of electricity. It is a wireless power transfer project that is achievable with few materials and some basic electronic components. This ...
