Better WLED LEDMap Generator

cstenkamp@gmail.com (Chris Stenkamp) — Tue, 16 Sep 2025 00:00:00 +0000

Code to create a WLED LED-Map (the JSON that tells WLED the positions of the LEDs) with some features that I didn’t find in any online editors: Dragging the mouse over the canvas fills all hovered cells, rescaling the map to a different size, inverting, and inserting LEDs in between existing ones.

Walden Floor 2025 @ Zugvögel Festival

cstenkamp@gmail.com (Chris Stenkamp) — Wed, 30 Jul 2025 00:00:00 +0000

This year, our Walden Floor transformed into the PetroLoco gas station that has been the site of a battle between the oil oligarchs and the ecological fraction. Next to the floor and the usual interactive installations, you could also play real-life Tuxkart here.

The Palapian's Spaceship

cstenkamp@gmail.com (Chris Stenkamp) — Sat, 28 Jun 2025 00:00:00 +0000

An interactive, networked spaceship you can actually board: players complete (or sabotage) missions across a dozen physical interfaces - buttons, joysticks, LED boards, sensors, etc - to either launch the ship or doom it, with everything driven by a Python/ESP/Unity stack. It’s modular, auto-resets regularly, and scales to festival crowds without manual babysitting.

First, there was the infamous PoolnudelschlagapparatPool Noodle Hitting Aparatus (PNHA). At Fusion Festival 2023, we had some pool noodles, some windshield wiper motors, and a wood construct to put a simple game into, so we did the only sensible thing to combine those things: You play Flappy Bird, and if you are too bad, you get hit with a pool noodle.

Relay-Boxes

cstenkamp@gmail.com (Chris Stenkamp) — Tue, 03 Jun 2025 00:00:00 +0000

A universal relay box for interactive builds: Ethernet-controlled with an integrated PSU, switching 230V, 12V, 5V and dry relays via OSC or Art-Net. I use it across projects like my Supertuxkart and the Palapa Spaceship to drive lights, fog, motors, and effects with simple, robust control.

Podcast Episode on LLMs for Software Engineering

cstenkamp@gmail.com (Chris Stenkamp) — Mon, 26 May 2025 00:00:00 +0000

In this (german-language) episode of Code for Thought, Carina Haupt (DLR) and I talk with host Peter Schmid about large language models in Research Software Engineering: where tools like Copilot genuinely help (routine tasks, tests, small scripts), and where real-world projects expose their limits (builds, requirements, missing project context). I share my current work on matching papers to repositories via embeddings at the project level rather than just functions - so models carry meaningful context across an entire codebase.

About me

cstenkamp@gmail.com (Chris Stenkamp) — Sun, 07 Apr 2024 00:00:00 +0000

✌️ I’m Chris and I like to build stuff.

For my Bachelor’s and Master’s, I studied Cognitive Science in Osnabrück with a focus on machine learning and language processing. It’s crazy how when I started my studies, Neural Networks were not even on the schedule and us students had to start the first course about them to get the ball rolling - by now there are 3 professorships regarding that. Even though I am not sure how much I’ll do in the future that has to do with any of the contents of my studies, I loved every bit of it, and took every chance I got to learn more, taking up to 60 credits per semester. It’s really great that in this course of study, besides the basic ones we could take a huge set of courses to fill our transcript, and I used that chance to, among many others, also do two thirds of a Computer Science degree on the side and followed whatever sounded interesting.

Adding dynamic content to HUGO

cstenkamp@gmail.com (Chris Stenkamp) — Mon, 19 Feb 2024 00:00:00 +0000

This website is build using Hugo, a framework to generate static websites from markdown-files. This means that after the compile-step, there are only pure HTML-files, which can just be hosted on any webserver. While this has several advantages in terms of eg. speed, debugability, search engine optimization and much more, a big disadvantage is that there is no straightforward way to include dynamic content. As everything is unchanged from the compilation on, allowing for content dependent on user input or from real-time data, or just including content generated from other web frameworks such as Python’s flask or Django, is not easy. However, thanks to Javascript, it is absolutely possible to incorporate such dynamic content, as I have done for example in my CV, which is generated with my custom CV-Generator.

Mount a QNAP NAS to your system using SSHFS

cstenkamp@gmail.com (Chris Stenkamp) — Sat, 06 Jan 2024 00:00:00 +0000

I never really liked NFS, so I wanted another way to mount a drive from my QNAP NAS onto my linux machine. As I haven’t found any sort of instruction for that online, I’ll post how I did it here, in case anybody searches for the same thing.

The how is hurdled mostly by the fact that you cannot install SSHFS onto QTS, as the package ist not available for it. But as so often, the solution is Docker. We’ll just create an Ubuntu-Container where we can install SSHFS, and mount the directory we want to share as a volume. This of course requires that you have a NAS with Container Station, allowing to use Docker Containers.

CAD and 3D-Printing

After finally (and only for now) accepting that a reliable sound2light-bassline-detection is probably more trouble than it’s worth, I next needed a way for tap2bpm instead. This, however, required new Hardware, and thus, I developed this Button-Board.

In this student research job for the Red Hen Lab, I worked on a pipeline that automatically detects hand gestures in large datasets of videos, involving OpenPose for Pose Recognition, Person detection, Person tracking, Scene detection and more, and deployed it on a HPC using Snakemake and Singularity to create a multimodal communication corpus from the Ellen DeGeneres show.

Stringart-Lamp

cstenkamp@gmail.com (Chris Stenkamp) — Sun, 27 Sep 2020 00:00:00 +0000

This is a lampshade made of string, made for a free-standing lamp with a single light bulb in it. It is designed dim the bulb as little as possible and just be a pretty ornament whether the light is turned on or off. As the bulb is pretty visible inside the shade, I recommend a pretty one with warm light, such as an Edison-bulb.

C++ Game: Bomberperson

cstenkamp@gmail.com (Chris Stenkamp) — Sun, 08 Mar 2020 00:00:00 +0000

Bomberperson is a maze-based multiplayer for 2 - 4 Players, that was programmed in a C++-project following up the respective university-course. All players should try to eliminate each other and be the last one standing. Player can place bombs which explode after a certain amount of time in multiple directions and can destroy obstacles and other players. Destroyed obstacles can drop power-upgrades that temporarily improve a Player. The Player is killed if they get caught by any bomb exploding or get hit by the Koopa-Shell too often.

cstenkamp@gmail.com (Chris Stenkamp) — Thu, 14 Sep 2017 00:00:00 +0000

Delving into the realm of self-driving cars for my bachelor’s thesis, I endeavored to optimize their tactical decisions, particularly speed, using cutting-edge deep neural networks and reinforcement learning in tensorflow within a transformed racing simulation. The resulting research platform, built on Unity, showcased the potential of real-time feedback and adaptability, offering valuable insights into the future integration of reinforcement learning in self-driving cars.
