Tesla coils are one of those builds that capture the interest of almost anybody passing by. For the naïve constructor, they look simple enough, but they can be finicky beasts—beasts that can ...

Tesla coil is very strong radio transmitter, and 1.7MHz is not free to use. It is above MW broadcast band and bellow amateur 160m band, in the area used by various coast guards which won’t be happy.

In addition to high frequencies, the coil could also generate extremely high voltages. With high frequencies, Tesla developed some of the first neon and fluorescent illumination. He also took the ...

Tesla’s Tower would be far more powerful than a small, experimental coil tested in a lab. Figure 1 shows the massive tower that was to be a new universal telecommunications system spanning the ...

Tesla coils do the same thing, but with a much more dramatic change in voltage. First, they employ a pre-made high voltage iron core transformer to go from 120V wall current to roughly 10,000V.

We’ve gone full-nerd with high-voltage experimentation—bringing together a laser bazooka and a Tesla coil gun to see which ...

The Tesla coil was invented by Nikola Tesla. It goes without saying not to try this at home, with even the similar woodwork technique of fractal wood burning getting a bad wrap for its danger risks.

Rob’s Tesla gun is powered by an 18 volt drill battery and uses a spark gap Tesla coil.The body of the gun itself is a Nerf gun, cast in aluminium. The housing for the primary coil and high ...

Engineering students at the University of South Florida have built a massive Tesla coils that shoots 15-foot-long sparks to the tune of Super Mario Brothers.
