After reading blog posts from BunnyCDN and Ctrl blog on the varying performance on top-level domains — I got curious on how .no would perform.

My file server, Zeta, has an mdadm RAID6 array with eight 4 TB disks. I want to expand, but before doing so I’m going to migrate to ZFS.

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 used the have the ultrawide monitor on a shelf in front of me, but I wanted it a bit closer and to be able to use the space below the monitor. So instead I used some scrap wood, a cheap VESA mount I had, and the brackets for the shelf to make it “float”.

I was quite happy with the previous Inter-Tech case I got, so I decided to get another. This time I got a rack mountable storage case, with 16 hot swap bays, for my file server Zeta. More thoughts and photos!

I’ve used this case a lot over the years — I first got one back in 2011, for my first rack mountable server. At the most, I had four of these in my homelab rack. They were relatively cheap, and easy to get.

Over the years I’ve sold most of them off, replacing them with Inter-Tech 4U-4129-N and 4U-4416. And my desktop computer have moved out of the server rack and into a regular desktop case.

I recently got a new rack mountable case from Inter-Tech — it was surprisingly cheap 😃 This is going to be the new server case for my hypervisor Alpha. Here are my thoughts, and some photos.

I made a simple HAT (Hardware Attached on Top) for the Raspberry Pi to read multiple DS18B20 temperature sensors — it was surprisingly easy. I used the measured temperatures to control a fan using Home Assistant.

My twin boys are, like their dad, fascinated by switches and flashing lights. I needed an excuse to use the Raspberry Pi Zero in a project, so I built them a WiFi MQTT controlled alarm module. With a couple of switches, some panel indicators, a buzzer, and a blue LED strobe.
