Can I ask for a few more details on your GPS NTP setup? That thought popped into my head the other day but I can't think of a real reason to do it, it'd really just be a cool way to waste some time.

It mostly is a cool way to waste some time. But why not? You'll have millisecond-accurate timing throughout your network

My longest running Raspberry Pis are using HifiBerry HATs. Acting as SnapCast clients, forming a poor man's Sonos system throughout the house. The oldest running Pi is a 2.

I have a pi 3 B+ running as an LTE to WiFi gateway. I'm not using the native WiFi but the ethernet is connected to an openwrt router.

Since I had ram to spare it also does:

- dhcp

- caching DNS + filtering

- Mqtt server

- GPS-based NTP server

- Openvpn server to my nas (at a different location) and vps

I have one running home assistant, I have one running a duet web server for a printer, and I have one that runs cncjs for a mill.

the home assistant one runs a reverse proxy and adguard/tailscale docker among other things.

they're useful but the price point sucks right now unless you absolutely need the IO ports/shields they provide. I have a PoE shield on my home assistant one that makes the installation very tidy.

My main one is for ADSB using adsb-lol.

I also have the Pimoroni Enviro+ in my living room. I've got their Grow kit somewhere as well, but... no plants since I moved.

I used to have a Kubernetes cluster running on some Pi3's, but they got a little too slow and I was bumping up against the lower memory. Lots of other self-hosted stuff, but it's all on some old off-lease computers I found cheap, not on a Pi.

We're running three right now:

One runs our boat's primary navigation system with Signal K and connects to the instruments via an NMEA2000 hat.

The second one is the boat NAS.

The third one powers an info display on the nav table.
