This is a collection of the projects that I did in my spare time.
|Active contribution to the open-source project Immich||"An open source, high performance self-hosted backup solution for videos and photos on your mobile phone"||https://www.immich.app/|
|corona-radius.de||A little tool that calculates an exact 15km radius around your hometown which you were not allowed to leave because of a COVID-19 related rule.||Github (Offline, not needed any more)|
|Flutter Cupertino Settings||A Flutter widget to create an iOS settings-table (static TableView).The library is used by various apps. I initially started the project to learn the Flutter framework.||Github|
|Haskell Enigma-I Simulator||I developed this after watching the great movie "The Imitation Game" to gain a deeper knowledge of how the Enigma-I machine worked. This project is NOT meant to glorify Nazi-technology.||Github (Leaving this just for fun. No more active development)|
|Nixie Tube Clock||I love the look of nixie tubes. I finally managed to build my own clock from scratch. It uses russian IN-12B tubes. I learned a lot about electronics during the project as I designed most of the circuits myself.||https://blog.mrupp.eu/nixie-tube-clock-with-seconds/|
|Smart Home CO2 Sensor||A WiFi enabled CO2 sensor based on the SCD30 sensor and an ESP8266 microcontroller.||https://blog.mrupp.eu/co2/|
