Please consider designing/making an Onju Voice PCB variant for the Google Home Mini (1st gen) with a Micro-USB charging port.

Bet quite a few people like myself also own many of the first-generation Google Nest Mini and are interested in converting them.

The downsides to the first-generation Google Home Mini are a worse speaker and worse speaker array compared to the newer generation, (as well as that Micro-USB charging port however you would probably want to still keep it a Micro-USB charging port since all of them shipped with a Micro-USB charger power-adapter).

Hi, First gen owner here. I love upcycling and would love to upcycle my gen 1 minis into being useful again. I followed a project for a while that attempted to make custom firmware for the default hardware but it ultimatly fell through. I love the idea of this as a HASS user but also as a ML dev. I have my own bot that currently runs on an old gaming laptop (working on integrating it with the native HASS "Assist"). Enough background. My main quiestion is this: Does anyone know what would prevent this board from working with the Gen 1 hardware? They appear to be the same size, have the LEDs in approx (if not exactly) the same location, etc. But it looks as though it may just fit in place. It may not be perfect but I'm assuming nothing a dremel couldn't fix..? I'm assuming the ribbon cable for the power delivery board would be different but other then that I can't (immediately) see anything that would prevent it. Maybe we could come up with a list of things that would need to change to help the dev process. I only have gen 1 devices so I can't really compair against anything other then some photos.

I would love for there to be an alternate version with a USB-C port as well as I have attempted to migrate all my devices towards that standard but that may have to come later.

Good luck. I can't even get PCBWay to accept the design. Apparently they have several engineers and a lot of them don't know how to put these together even with all the data we provide. Honestly I'm stuck just getting boards for what's available. It'll take an electrical engineer to accomplish what you want without doing it yourself. Sad but true

Hello. I've also this GHmini and I'd love to have a new variant of your PCB for this device. You're doing an amazing job ! Thank you for this :)

Seems like there has been a faulty update for the original Home Mini, where devices got bricked (9to5google). With more devices being bricked, it would be awesome to have an alternative way to use the hardware!

The cost of 5 PCBs isn't small (around 80€-85€ with components), but maybe I will make the investment and test out what is preventing the usage of the PCB. I was looking at images of both PCBs, which are mostly similar.

Very interested in a home mini gen 1 version too here. In France they go on the used market regularly for 10€ but I have never seen a gen2 go for under 25€ most ask 30€ I already have 8 of the gen1 at home and using it happily with Google just sad I can't run it locally as most everything I do is triggering HA devices from GH... (And listen to music which might also come one day to the onju 😁) I'm ready to try it out and happy to shell out the ~90€ for 5 boards but not so much 5x30=150€ for the shell...

Really hoping someone with more skills than me can make a gen1 version of this ❤️

Unfortunately, I don't know how to correctly modify the pcb and test it to be able to order it from pcbway. But I tried the violent way... which mean just cut and try to force fit the pcb inside the google home mini 1st gen. So i notice a few things :
