This is a prototype on a Variable Frequeny Driver or VFD. With this circuit we would control the frequency of high AC voltage and by that the speed of induction AC motors. Since we work with high voltage, is a dangerous circuit so be careful. The idea is to turn 230V AC voltage to DC vo... view more

A Tesla coil generates a high frequency high voltage inside of the main coil and that ionize the air at the end of the copper wire and the air will glow due to the created arcs. Depending on the tesla coil power, the arcs could ger bigger. This project is very cool to look at but not just that. I... view more
