Cluster of Pi4 8GBs. Bought pre-pandemic; love the little things.

Nomad, Consul, Gluster, w/ TrueNas-backed NFS for the big files.

They do all sorts of nifty things for us including Nightscout, LanguageTool OSS, monitoring for ubiquiti, Nextdrive, Grafana (which I use for home monitoring - temps/humidity with alerts), Prometheus & Mimir, Postgres, Codeserver.

Basically I use them to schedule dockerized services I want to run or am interested in playing with/learning.

Also I use Rapsberry Pi zero 2 w’s with Shairport-sync (github.com/mikebrady/shairport-sync ) as Airplay 2 streaming bridges for audio equipment that isn’t networked or doesn’t support AirPlay 2.

I’m not sure I’d buy a Pi4 today; but they’ve been great so far.
