I built a rack out of wood in 2004 — it was at home, and a lab, of sorts, so I guess that makes it a homelab 🙂

Let’s take a trip down memory lane and look at 20 years’ worth of homelabbing ❤️

While doing some WireGuard testing between local peers; I noticed weird performance issues on my virtual Mikrotik router. This lead me down a rabbit hole of testing the layer 3 throughput on my virtual CHR.

The bitrate started at close to 10 Gbits/s, but then dropped to 3-4 — only in one direction 🤷 Time to investigate…

My homelab rack has been running as is for a while now — it’s time for a few new projects.

I’m rearranging stuff to better utilize the space, looking into 25 Gbit networking, and putting a HP Z440 server to good use 🙂

We have a Dakboard digital calendar in our kitchen — showing lots of house and temperature data. So naturally; it must show the actual outdoor temperature as well.

To do this I used a Raspberry Pi 2, and a DS18B20 HAT I made some years back.

Our Komfovent balanced ventilation system is pretty bad at accurate timekeeping — the time drifts several minutes over the course of a few months. This is a bit annoying as the operator panel is prominently located on the second floor, and we use it to tell time.

Luckily; the time can be set using the Modbus interface.
