The term “Gedöns” describes objects that are not absolutely necessary for everyday use and are therefore considered superfluous. In my case, it describes my home lab very well — supplemented by the syllable “Tech”. 🤪

My Daily Companions

I strive to use resources sustainably and consciously, opting to repair rather than replace items whenever possible. This philosophy is reflected in the list of my daily companions. The only exception is my iPhone, which is provided by my employer and replaced approximately every three years.

  • Apple iPhone SE (4.7″, 2022), 128 GB
  • Apple iPad Pro (10.5″, 2017), 256 GB
  • Apple MacBook Pro (2021), M1 Pro, 1 TB, 16 GB RAM
  • Samsung 4K Display
  • Logitech MX Keys for Mac
  • Logitech MX Master 3 for Mac

As a computer scientist, I don’t just use my PC for browsing the web or writing letters only. I’ve been self-hosting smaller services, such as my password manager, for several years to keep my data secure. Last autumn, I took a significant step by replacing all possible services with self-hosted alternatives, including my own social media services and mail server.

Proxmox Cluster

Below you will find a few up-to-date (29.05.2024) photos of my “home lab”. As you will see, there is still room for improvement in terms of professionalization and at some point I would like to upgrade to a 19” rack. Currently, however, family comes first, and I live with the equipment I already own.

External Oracle Host

While I love self-hosting applications, I prefer to ensure reliability for communication services. Thus, I host my mail server and Matrix instance on a „pay as you go“ plan in Oracle’s Frankfurt data center.


  • Oracle Standard A1.Flex, 4 OCPU, 24 GB RAM, 200 GB storage



  • FRITZ!Box 7590 AX connected to Telekom DSL (250 Mbps down, 40 Mbps up)
  • Internet fallback via ZTE LTE Stick with Vodafone contract
  • 2x TP-Link TL-SG608E (one for private network, one for Proxmox VLAN)
