I have a Raspberry Pi that runs pihole and Wireguard exclusively. My home server is a Kubernetes cluster running on an old desktop PC and 2 Intel NUCs.

The reason for the separate Pi was essentially because I only had the desktop PC initially, and for a while I had a faulty CPU, making the desktop PC crash or become unresponsive, so it helped a lot having DNS and VPN access separated from the instability.

I have a very nice scale that is accurate to 0.1 g and updates very rapidly, because I’m a coffee nerd, and need the precision to accurately dose my espresso. But one of the jokes in the community is that the only two groups of people that need scales like these are coffee people and drug dealers…
