Would like custom printed circuit board (PCB) replacements for Google Home and Google Nest to run ESPHome firmware and be based on same ESP32-S3 + XMOS DSP chip combination as the official Home Assistant Voice Preview Edition, anyone else what would also be interested in this?
Are there any PCB designeers / electrical engineer in this community with time and interest to design and build PCB schematic for new DIY custom ESP32-based third-party alternative circuit-boards for example the Google Nest Mini and Google Home Mini (smart speaker devices) that will work as drop-in PCB (Printed Circuit Board) replacement boards similar to the old Onju Voice project, but unlike it instead be designed to use a newer updated design that also adds an XMOS-chip (advanced DSP connected to the microphone for voice quality cleanup) to match the more modern hardware specification of the proginal Home Assistant Voice Preview Edition as well as have a fully free and open-source hardware design?
That is, it does not seem like justLV will return to continue developing his onju-voice PCB design to add an XMOS chip, plus the fact that the original project was never being made into a fully open-source design without restrictions, so I was wondering and hoping that some other talented electrical engineer(s) with PCB design experince/skills will step up to make some new PCB designs for the same concept + publicly release all that as fully open-source PCB designs and schematics that has a similar concept as the Onju Voice project but instead being made as a fully open-source drop-in replacement circuit-board for example Google Nest Mini / Google Home Mini (smart speaker) series and also using the same ESP32-S3 but adding XMOS xCORE chip same as the new Home Assistant Voice Preview Edition reference hardware from Nabu Casa?
So essentially an new custom open-source circuit board for converting Google Nest Minis into Home Assistant Voice smart speakers:
As most of you probably already know; Nabu Casa development team together with other ESPHome and Home Assistant core developers have made progress by leaps and bounds over the last year and with the release of their official Home Assistant Voice Preview Edition reference hardware. Read:
Hence concept of the Onju Voice drop-in PCB replacement is at least in theory showing more promise than ever and better user case for a larger audence, however its lack of an XMOS DSP MCU chip and missing dual I2S bus makes the current PCB design obsolete as that the improved user experience you get with the XMOS chip added is a night and day difference:
That in turn take inspiration from the XMOS XK-VOICE-L71 Evaluation Kit (development kit):
Therefor I think optimal goal would be new PCB designs based on ESP32 + XMOS chips with royaltee free schematics as fully open-source hardware that anyone could have manufactured themselves or order pre-assembled PBC-replacement-boards for Google Nest Min (and Google Home Mini) directly from PCB-manufacturing-service such as for example PBCWay, OSHPark, or JLCPCB, that offers "shared projects" community designs, (hence wish for an open-source license without commercial restrictions clause), that will enable people to re-puropse their existing Google Nest / Google Home smart speakers within their enclouses.
There are already huge stock of those out there and users who might be incline to migrate on a budget can be willing to thinker with such a project of such a PCB is designed released by electrical engineer(s) with the skills, time and interest to make this happen.
Any one here perhaps got contacts at any one of those PCB-manufacturing-services that might be willing to run and sponsor a contest or similar effort to speed up such a development effort?
