Tesla coils are one of those builds that capture ... of this build style is the shift from the originally used spark gap commutator to that of a direct AC drive via a MOSFET oscillator.

the coil (transformer) itself, and adjustable spark-gap electrodes. Why these components, and what do they accomplish? To set his oscillator "ringing," Tesla employed sudden discharges ...

(Photo: Wikimedia) The Tesla coil requires one more thing: a capacitor to store charge and fire it all in one huge spark. The circuit of the coil contains a capacitor and a small hole called a spark ...

Explore the power of wireless energy as you build your own ‘baby Tesla coil’ (or Slayer Exciter) using Lego Technic! This experiment may not be a traditional spark-gap Tesla coil, but it ...

In 1888, Heinrich Hertz of Germany confirmed experimentally that an electric spark propagates electromagnetic ... device still known today as a Tesla coil. Patented in 1891, this invention took ...
