The Tesla coil driver circuit is based on a version of quite popular Slayer Exciter Circuit. The circuit is powered with mains power supply that gives out 9V 1A DC to the electronics: The electronics is pretty simple: One power transistor, few passives and the Tesla secondary coil: The product I recieved looked somewhat different than on the product page picture showed, but the most important details were OK. “Can light of incandescent lamp, energy-saving lamps, integrating scientific demonstration and entertainment, suitable as a magic props used in science and education, science and technology museum and school exhibits, etc.”
They are old, but I this they are still cool!ħ00K Mini Coil Tube Neon Glow Coil With Transparent Plate Power Supply For Tesla page promised following technical specifications: They have become a way to counter the stereotype that science is boring. It is used to produce high- voltage, low- current, high frequency alternating-current electricity.Ever since Tesla’s 1890s lectures, Tesla coils have been used as attractions in educational exhibits and science fairs. Let’s start with basics:The Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. 700K Mini Coil Tube Neon Glow Coil With Transparent Plate Power Supply For Tesla is one such device I tested. There are some portable tesla coils you can buy online that say, “safe, low current”, and yet they still produce lightning and have a high voltage output.
Tesla coils and other high voltage equipment that make sparks are always entertaining and potentially dangerous.
