An Audio Brick For Your Smart Home
If youβve ever wanted to pump sound to all the rooms of your house, you might use any one of a number of commercial solutions. Or, you could go the more DIY route and whip up something like the Esparagus Audio Brick built by [Andriy].
The concept is simpleβitβs a small unit, roughly the size of a brick, which streams high-quality audio. Itβs based around an ESP32, which pulls in digital audio over Wi-Fi or Ethernet. The microcontroller is hooked up to a TAS5825M DAC, which comes with a built-in amplifier for convenience. The Esparagus is designed for integration with Home Assistant, allowing for easy control as part of a smart home setup. Itβs also compatible with Spotify Connect, AirPlay, and Snapcastβthe latter of which provides excellent sync when using multiple units across several rooms.
Design files are available on Github for the curious. Weβve seen other neat projects in this space, before, tooβlike the charmingly-named OtterCast. Video after the break.
