Short review of small music Tesla Coil with Bluetooth
Pavleski Apr 25,2024
 A Solid State Tesla Coil (SSTC) is a type of Tesla coil that uses solid-state electronic components to generate high-voltage, high-frequency alternating current electricity. The use of modern semiconducting elements makes it possible to make such miniature and efficient devices. In this video I will present you a miniature Tesla Coil that can be purchased online for a price of several tens of dollars. The shipment contains a Tesla Coil module, a 48V/2A switching power supply, a needle thro...

Music Tesla Coil
ELECTRONOOBS Sep 28,2023
This below is a Tesla Coil and it plays music with plasma. And I bet that you wonder, if it is a Tesla coil, where is the coil? You would expect a copper coil with a huge amount of loops. Well, this Tesla coil has its windings in 2D, meaning the windings are on the flat PCB. That’s right, using the services of PCBWay I was able to manufacture these very thin coils covered in gold for more conductivity, with over 180 loops, so it creates high voltage. In this post I will ...
