We’ve seen a fair amount of Tesla coil builds, but ones using vacuum tubes are few and far between. Maybe it’s the lack of availability of high power tubes, or a lack of experience working with them ...

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 ...

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 ...

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 ...

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 ...

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 ...

Technically, this is called Teslaphoresis. The idea is to use a Tesla coil that creates high magnitude diverging electric fields. These fields then can cause nanotubes to assemble into nanowires. Here ...

What do you do when you find a 5 kW transmitting tube in your local electronics store? If you are [TannerTech], you build a vacuum tube tesla coil. This isn’t the usual little wimpy coil, but a big ...
