A collection of data visualizations
A gallery of recent data visualizations, from simple plots to conference posters and even a video.
Pretty pictures with angular random walks
Let’s see how basic random walks can be extended a bit to create interesting visuals.
How to write coding articles in plain Python files
How to convert a Python file with some inline block comments to a beautiful markdown document
Chirp detector
Electric fish produce fast frequency sweeps to communicate, called chirps. Here, I detected these chirps with a CNN-classifier on spectrograms that was trained on data I simulated.
Labeling images with Label Studio
A guide on how to set up Label Studio to correct pre-annotated images of a YOLO dataset locally.

PlatformIO: Hardware dev from the command line
An introduction to PlatformIO, a tool that makes software development for microcontrollers easier.
Colorblind direction cells
Some neurons in thet zebrafish brain respond to movement direction. We recorded and analyzed the activity of these neurons and showed, that these cells probably rely on luminance alone to perceive motion.
Electric duet
Some electric fish synchronously modulate their frequencies in duets. I detected these events using a custom covariance-based event detector on frequency estimates from spectrograms.
