This page lists various activities around the web and in real life where you can find me occasionally.

technikum29 Computer Museum

I operate the private technikum museum for computer and communication history. Within the hobbyist vintage computing community, it takes a distinct position thanks to its one-of-a-kind dedicated building, allowing it to offer a home to extremely heavy vintage computers such as vacuum-tube computers, punch card systems and mainframes. Since 2019, together with a small team of highly motivated volunteers, we shape this heritage.

The museum is located near Frankfurt, Germany. We have about 40 public events per year hosted in the museum and carried out by my fellows.

Former voluntary work

In the last years, I was working on various positions in my free time:

• Voluntary judge of financial matters (Finanzrichter) for the election period 2021-2025 at the Finanzgericht Münster.
• Voluntary member of the parental council at the local county for the election period 2021-2022, called JAEB (Jugendamtselternbeirat). This is kind of a position related to municipal politics.
• Voluntary member of the supervisory board (Aufsichtsrat) of DenktMit eG for the election period 2023-2024.

I also support the work of/at CCC and Wikimedia DE.

Let's go, start it up!

I put demands on my readers: You are required to detect irony. But, spoiler alert, each of the following startups has a valid core of truth. Can you find it?

• Ohrenbaum GmbH is a small holding located in Münster, Germany. It was founded in April 2020. As a founding director, I'm doing the strategic direction.
• Svantic institute is a novel research institute located in Münster, Germany. It was founded in April 2021 and is currently operating privately.

Trivia

I'm on the web since 2000 and I had many generations of websites, some (most) of them being down nowadays. Sven.Köppel.org was my website in the 2010s. Ufopixel.de is another old project I was involved in. There are still plenty of ressources which can be found at my old website at Goethe University.

There are a couple of other Sven Köppel around, which are not me. These are for instance @testpilot76, this instagrammer or that person in Hamburg.
