The circuit is basically a transformerless mains power supply that can for example turn your 230V AC to 5V DC. It only requires a few components and thus is very cheap to build. But on the other hand, it does not feature a galvanic isolation which makes it quite dangerous. So sit back and enjoy the video to learn all about the circuit! Let's get started!
