Ask HN: Is there any open source/open hardware Echo Dot alike?

by nudpiedo on 8/11/2023, 9:30:27 AM with 9 comments
Hi all, I wish to have my own customized smart speaker like echo dot, but fully programmable (Linux level).

For whatever reason I cannot even find any hardware alternatives, just some people who hacked the echo Dot’s bootloaders.

If anyone know any alternative hardware and projects to create such a platform, I would be thankful for that.

    Unfortunately it isn't going as well as they'd hoped: https://mycroft.ai/blog/update-from-the-ceo-part-1/

    Or you could try reSpeaker (different options available): https://wiki.seeedstudio.com/ReSpeaker/

    The hardware is rather straightforward, something like a Raspberry Pi with off-the-shelf mems microphone module, powered Bluetooth receiver, battery + management (if you want it portable), and potentially some UART/SPI interface for more specific sensors/comms. The software I don’t have any direct experience with, but potentially something like Ada from HomeAssistant would be functional and easy to implement/integrate.

    Is there a particular part of this that seems most challenging for you? Would you be interested in developing something to fill this potential gap? I’m toying with a lot of the same tech right now, I’d be glad to contribute.

    This is the closest I have found, unfortunately, devices have been out of stock in many stores: https://github.com/espressif/esp-box

    I think you can use a Bluetooth conference speaker for the audio part, they now have multi mic arrangements, echo cancellation, etc.

    I created Willow, which uses the Espressif ESP BOX:

    Boombeastic Mini’s Pi case design could be an option?
