Hyperion is my second Tesla coil. Also a "classic", spark-gap Tesla coil, it was built mainly out of the stuff that remained from the construction of Zeus (previous coil). I tried to apply what I had learned during the construction of Zeus to build a much better coil, and it worked : although its power is only 2/3 of Zeus' power, the improved design of several of its components makes it achieve similar arc length (about 40 cm) ! As for the name, Hyperion (`Yπερίων) was a Greek deity, the Titan of light, and the name sounded nice for a Tesla coil.
Total project cost (estimated) : 900 €.
These pages will focus mostly on the construction and component design, as the complete theory of operation is already discussed in Zeus' pages. I'd suggest you have a look at them if you are completely new to Tesla coils before reading what's next.
Here's already a rapid review of Hyperion's characteristics.
|Transformer||Neon sign transformer (NST), 6kV, 25mA|
|Primary capacitors||Eight 150nF Cornell-Dubilier 942C connected in series|
|Primary coil||Conical spiral, 7cm inner radius, 25cm outer radius, 7.125 turns|
|Spark gap||2-elements, static type with (powerful) quenching fan|
|Secondary coil||SWG 27 magnet wire, ~1000 turns, 40cm height|
|Top load||Toroidal geometry, 10cm minor diameter, 30cm major diameter|
