I’m using Prometheus to monitor my home office and homelab, I figured it would be cool to have a stack light show the active warnings and alerts from Alertmanager. So I made a HAT (Hardware Attached on Top) for the Raspberry Pi to drive a five-colored stack light.
I got a Unifi 16XG switch, it was too loud. I made it quieter using Noctua low-noise adapters.
My homelab and home office got way too hot, time for some proper ventilation.
After I stopped smoking cigars in the man cave, the ventilation needed to change.
I’ve had a server rack for many years, but never really gone all in. Well, that changed…
