FPS Raytrace: Wolfenstein 3D Clone in Android with Jetpack Compose

Fri, 18 Apr 2025 00:00:00 +0000

A first-person shooter game demo for Android using raycasting rendering with Jetpack Compose. Think Wolfenstein 3D-style gameplay but running on a modern Android device with touch controls and ML-powered enemies.

What is Raycasting? Link to heading

Raycasting is a rendering technique used in early 3D games like Wolfenstein 3D, Doom, and Duke Nukem 3D. Instead of full 3D polygons, it casts rays from the player’s view into a 2D grid map to determine wall heights. This creates a pseudo-3D effect that runs efficiently on limited hardware.

I Taught My Phone to Know I'm Lying on the Couch. Here's How.

I’ve been fascinated by real-time signal processing for a while. You know that feeling when you’re watching a live graph of sensor data and it wiggles around in response to the real world? That’s basically digital sorcery and I love it.

I was thinking where to get the data and what to classify.

One day I thought: what if I could make my phone figure out what I’m doing, just from its motion sensors?

Real-time MAVLink Drone Monitoring

Fri, 18 Apr 2025 00:00:00 +0000

This project provides a real-time MAVLink-based drone monitoring system. It connects to a MAVLink-enabled drone, listens for messages, and visualizes data such as message frequencies, detected systems, and requested data streams via a web interface.

Features Link to heading

MAVLink Connection: Automatically connects to a MAVLink system and listens for messages
Live Data Display: Shows detected MAVLink systems and components
Message Frequency Monitoring: Tracks expected vs. actual frequencies of MAVLink messages
REQUEST_DATA_STREAM Capturing: Logs data stream requests from the drone
Web Interface: Real-time dashboard for monitoring
Reset Functionality: Allows resetting the collected MAVLink data
