• Personal gear: Canon 6D with Samyang 2.8/14mm lens. Great for low-light conditions

Secure backup communication

I created a secure backup communication network, a network of microcontrollers that can communicate securely (symmetric encryption) without the need for any external cellular network. All you need is the microcontroller, an antenna, and a keyboard (the MC has its own keyboard interface!). It currently works over a distance of multiple kilometers. This is work in progress in my free time. Current todos include publishing the PCB layout, improvement of the currently broadcast-based protocol, and hardware encryption.

CNN code

A convolutional neural network implementation based on only NumPy. No PyTorch, no Tensorflow. It works pretty fast, but the purpose was rather to get a deep understanding of all underlying mechanisms.

Favorite things

  • Physics and computer science latex template: atlas.
  • A side project is developing a software package to track changes on websites and store and process them in real-time. We are in the final testing phase and aim to publish v1.0 on Github in March 2022. This quiet complex software package ranging from dynamic programming to database processing could be used in empirical research on online behavior, such as reactions to the introduction of GDPR.
