In our new house there is an 20 m² basement, it consists of two rooms — both 10 m². I have turned the inner room into my new home office/server room, with my electronics lab and homelab.

I’ve got a tiny computer lab at home; a 29U rack with servers, UPS, ATS, PDU, 10 Gbit networking, OPNsense, and all the cool stuff.

I first got the server rack back in 2011. At the time I lived alone in a house; I had a UPS, single server, a few cheap NAS’ and a switch in it. When I met my girlfriend, and we moved together about two years later the rack went into storage. And it stayed in storage until we bought our house late 2014, where we currently live. The rack was put to use in my home office in the basement, but not really utilized much. It’s only lately, and after I found /r/homelab, that the rack was truly put to use in my current homelab.

Electronic switch for LED lights, 4 channels, 9 to 24 volts in, 5 volts out. Uses an AVR ATtiny2313 microcontroller.

Simple monitoring module for the essentials in the rack box project; power supplies, fuses and communication. Uses an AVR AT90S2313 microcontroller.
