TL;DR
The SendspinZero is a DIY audio receiver that allows you to set up multi-room audio systems using open-source components. It’s built around a Waveshare ESP32-S3-Zero board, which is an affordable microcontroller, and it can be assembled with off-the-shelf parts that total around $10. The design includes a 3D printed enclosure, and while the core functionality is about audio playback, it also supports features like displaying album art on a screen and controlling sound-activated lights, which are expected to be added soon.
Why This Was Curated
The article presents a practical DIY project that integrates hardware and software, making it highly relevant for software developers looking to learn about embedded systems. It is accessible and actionable, providing clear instructions and components for building the audio receiver, while also introducing a novel open protocol for audio synchronization.
