My Notable Projects

Realtime Aircraft Tracker

This is a plane tracker made with a Raspberry Pi and a Radio Antenna, it receives radio signals broadcasted from airplanes which contain position and flight data, the planes are then displayed in their live position on a radar display and their data is uploaded to my Firebase DB.

The Firebase data is pulled by a Kotlin app I made to show stats and let me control the plane tracker.

Satellite Ground Station

A ground station setup for receiving and decoding satellite imagery using a custom V-Dipole antenna. The system captures satellite radio transmissions and processes them into viewable images from weather satellites such as Russian Meteor-M series and American NOAA satellites.

Here you can see my setup and some examples of images I've received from Meteor-M2 3 and 4 satellites when they were passing over West Europe.

My Homelab

My Homelab which consists of self hosted projects and services, some of these include:
