Only two weeks after we came home from the Maker Fair, a new project was waiting for us. We were invited back to Hannover to the art festival called Hola Utopia. But not as guests, as artists! And our main kicker would be the Dot-Bot, […]

Maker Fair 2026
Since the day I started calling myself a maker, I thought about showing some of my projects to a larger audience. This year, I finally decided to do so. I registered as an exhibitor for the second biggest maker fair in Europe and the third […]
Dot-Bot Software Upgrade
The third time is a charm, they say. And apparently this also holds for software projects. I assure you that a fresh start with a clear vision is often so much more productive than trying to fit an old project into a new shape, which […]
Electronic Kalimba
This blogpost is longer than what I usually write about my projects, mainly because this project also became much bigger than anticipated in the beginning. The TL;DR is a 100% custom, handheld, battery powered MIDI controller / synthesizer constructed from two custom PCBs stacked together. […]
3D Terrain Generator
Here is another one of my weekend projects I happened to work on way more than expected. The initial smaller goal was to upgrade the terrain generation for the HexTexMex project to have more variation in the map generation. First I started with some random […]
Bahnhofs Steuerung 2000
About a year ago, my dad asked me if I knew a way to control a bunch of tiny LEDs to light up his model railway buildings. At the time, I didn’t have an immediate solution, but I was up for the challenge. He had […]
Crossword Auto Solver
Some time ago, I saw a challenge online from the Luxembourgish newspaper RTL. They released a crossword every week, for years. Now their new challenge was to get all the results from the crosswords published to this date to win a nice price. The thing […]
Marshmallow Mystery
For almost two years, I was part of the team that developed the Augmented Reality (AR) game called Marshmallow Mystery. It was the brainchild of the theater group GRIPS from Berlin Germany. Their kids program “Rakete jetzt!” imagined the story of a summer camp, where […]
Electronic Guitar
The idea for this project came from my younger sibling. When he was visiting me in Berlin during the summer of 2022, he talked about how it would be cool to have a guitar style midi input device with clear tactile feedback. He already tried […]
DOT-BOT 2.0
This is not just a small update. Almost every part of the project got redesigned and many technologies changed. This is such a major leap forward that for me it feels like a new project altogether. After the update, the combined error was reduced from […]
