I've been trying to get microk8s 1.21/stable working on Ubuntu 21.10-arm64 on Pi-4 and it seems that perhaps microk8s doesn't like the new default in Ubuntu 21.10 ( from the...

I did this. On the stretch distro for a long run node. This is my CO2 and particle detector station. ``` pi@CO2mon:~ $ sudo mv ./Mycodo ./645_Mycodo.saved pi@CO2mon:~ $ sudo...

No worries Kyle, I still had a good time while trying. I'll follow your suggestions and try some more. Its worthwhile to do, I think. Thank you for giving containers...

I have something new to add, the gpio I2C I suggested cannot use the standard mux dtoverlay to obtain bus devices in /dev. I think your mux code probably works,...

After exploring options, it becomes clear that USB is the way to add serial sensors to a Pi. I've been playing with a SC16is750 for UART and well, it becomes...
