If you want to see how this circuit works, the other circuits we have for this, the use of a flyback transformer and more examples, check this post. I will show you everything you need to know about this circuit, then we assemble it on a prototyping PCB for one circuit and on a PCB kit for the... view more

In this tutorial I'll show you how the fluorescent tube creates light with electrodes creating electrons, mercury vapor and phosphor inside the tube. Then we analyse how the high voltage is created with the starter and ballast and then how the current flow is keept throgh the tube. I hope ... view more

Project - Mini Plasma Speaker (5 volt powered) | in Speakers

Plasma is quite remarkable,and the ability to create sound just by modulating it's frequency is amazing. I am really into plasma and HV science,and so I decided to try my best to create the smallest plasma generator ever (that can play music,of course). It features a small flyback transformer (th... 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
