Plasma Speaker
The Plasma Speaker is a device that utilizes a high-voltage plasma arc to play music. The project consists of three different circuits, a signal generator, an amplifier, and an H-bridge digital to analog converter. In this project, we will teach you the basics of audio amplification, pulse width modulation (PWM), digital to analog signal conversion, and using high-voltage transformers. This is a great way to learn circuit analysis at an advanced level.
