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.
- nudpiedo 3y agoVoice capture quality wouldn’t be any great from all directions as echo dots have somehow solved with multiple microphones. Also is the device facade.
- nativeit 3y agoGood point. My personal philosophy is to lean into these problems as opportunities for a DIYer. So otherwise absurd choices for a mass-produced design become the defining characteristics, like making a Bluetooth/voice assistant with a large-diaphragm condenser microphone capsule, and since it’ll need 48V for the phantom power, why not have a lovely vacuum fluorescent display and/or tube preamp between the DAC and speaker? Pile it all into custom machined aluminum chassis, and enjoy your new steampunk Nest.
