Tesla coils are beautiful examples of high voltage hardware, throwing sparks and teaching us about all kinds of fancy phenomena. They can also be quite intimidating to build. [William Fraser ...

[Teodor] writes in with a unique Tesla coil he designed and built ... This creates a significant voltage boost, helping produce very high voltages from such a low input voltage.

The Tesla Coil was a high frequency alternating current transformer capable of creating high voltage at low current. Now, in addition to the first and only park (in Downtown Buffalo) named in ...
