Projects

Selected open source hobby projects. More on Github.

Black HoleGitHub Repo stars

A real time ray-traced simulation of a Schwarzschild black hole using THREE.js. The contributions of various special and general relativistic effects can be toggled from the GUI.

SIMD KalmanPyPI downloadsGitHub Repo stars

Fast Kalman filters in Python leveraging single-instruction multiple-data vectorization. That is, running n similar Kalman filters on n independent series of observations.

AutosubsyncGitHub Repo stars

Automatically synchronize SRT subtitles with audio using AI & Machine Learning. Automatic speed and shift correction, typical synchronization accuracy ~0.15 seconds. Available as a Python package.

Corona SnifferGitHub Repo stars

How anonymous is the Apple/Google BLE contract tracing system (GAEN/ENS)? A proof-of-concept BLE sniffing attack against the system.

WebGL Raytracer

Run a GPU-powered bidirectional raytracer in the browser and experiment with different scenes and rendering options. GPGPU now possible without spending hours installing CUDA!

Tree of Life

An interactive visualization of the Open Tree of Life using d3.js. The entire tree with approximately 2.3 million identified species as leaf nodes is browsable through the application.

JS car

JavaScript 2D car dynamics simulation. The physics model is as simple as possible: Frictional forces are applied to two points: the center of the front and rear axle.

QR cloner

Scan a QR code to move it from your computer screen or a printed paper to your phone. The code is saved on the phone and can later be displayed to QR code scanners.

Puzzles

Archive of ad hoc algorithmic solutions to physical puzzle games. Mostly throwaway-quality code, some of which only runs with Python 2.

AR-3dtris

Sort out a frustrating mess of falling 3D blocks in Augmented Reality on Anrdoid or the browser. A game and an experiment using WebGL, Emscripten and ARCore.

Mersenne Twister

Can you spot the difference between the C random number generator and Mersenne Twister?

Baro floor height

An Andoid app for measuring the height of storeys and buildings using the barometer.
