Tesla coils are one of those builds that capture ... However, this is quite a small unit; with larger ones, the power is much higher, and the resulting discharge sparks much longer.

Everyone interested in electronics should build at least one Tesla coil. But be careful. Sure, the high voltage can be dangerous, but the urge to build lots of coils is even worse ...

particularly the Tesla Coil (originally called Tesla Oscillator) – a high frequency oscillator that enabled the inventor to conduct a series of revolutionary experiments including wireless ...
