Announcing LibreEcho - Open, Self hosted OS for Echo Gen 2

preview.redd.it/qlivckaqnpjh1.png I've been working on replacing the software stack on a full-size second-generation Amazon Echo. The project is called LibreEcho, and at this point the device is running Linux 6.1 with enough of the original hardware working that it's starting to become genuinely useful rather than just an embedded Linux experiment. So far we have: - boot and recovery - A/B rollback - Wi-Fi - Bluetooth A2DP/AVRCP - AirPlay through the original speakers - LED control - local web administration - signed OTA updates - local wake word, STT and TTS work in development The audio side has probably been the most difficult part. The original hardware has a fairly involved codec/clock/amplifier path, and the microphone system is considerably more interesting than a generic USB mic. The aim isn't to recreate Alexa. I'd rather turn the hardware into a general local voice/audio endpoint that the owner controls, with Home Assistant being one obvious integration. We're getting close to the point where I need to test it outside my own network and development device, so I'm also interested in hearing from anyone with a spare full-size Echo Gen 2 who is comfortable recovering embedded hardware if something goes wrong. This currently only targets the tall/full-size Echo Gen 2, not the Echo Dot. There's more detail and some screenshots here: libreecho.org
