Introduction: WOODEN WIFI SPEAKER
This is an "easy to use" music player with a reasonable sound quality. The main objective at the start of the project was that the box had to have only one cable, the mains. The way to achieve this was putting a chromecast audio inside the box. The rest of the electronics are just a low budget ebay class D amplifier and the power supply.
