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 ...

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 ...

Educational electronics kits like the one from Minty Geek are a great introduction to the world of circuit building and electronic tinkering, but are perhaps a little too basic for more advanced ...

The role of J.P. Morgan in getting Tesla's Tower built. The fundamental operation of a Tesla coil. Dealing with EMI generated by a Tesla coil. When I lived in Long Island, N.Y., I had a most ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Among his numerous innovations, Nikola Tesla dreamed of creating a way to supply power to the ...

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 ...

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 ...

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 ...
