PX4 SIH running on real flight controller hardware with Unity visualization

Running PX4 SIH on Real Hardware: Custom Firmware for In-the-Loop Flight Simulation

Getting PX4’s Simulation-In-Hardware (SIH) module running on a production flight controller — discovering the firmware doesn’t include SIH, building a custom PX4 with flash-trimming, fan-out routing serial MAVLink to both the simulator and ground station, and connecting it all to the Unity visualization pipeline.

Scripted Hardware Testing for PX4 — MAVLink Shell, Docker, and pymavlink

How to script PX4 hardware verification using pymavlink’s SERIAL_CONTROL protocol over a USB connection — download CI firmware, flash from the command line, and run NSH commands programmatically. No QGroundControl required.

PX4 Autopilot: A Practitioner's Guide to Troubleshooting, Debugging, Building, and Testing

Everything I learned contributing 6 PRs to PX4-Autopilot in a single session — from Docker-based builds and sanitizer workflows, through uXRCE-DDS session debugging and MAVLink signing analysis, to SITL integration testing. Real bugs, real fixes, real build output.

PX4 SITL to Unity in Docker: A 60-Hour Odyssey

Connecting PX4 SITL to a Headless Unity Simulation in Docker: A 60-Hour Debugging Odyssey

A three-day odyssey connecting PX4 flight controller to a GPU-rendered Unity drone simulation running headless inside Docker — through licensing labyrinths, shader abysses, coordinate system riddles, native library dragons, and a TCP protocol twist ending nobody expected.

Unity Headless in Docker with GPU, RTSP, and MAVLink

Running Unity 2019.4 Headless in Docker with GPU Rendering, RTSP Camera Streaming, and MAVLink

A detailed technical account of containerizing a Unity 2019.4 drone simulation with GPU-accelerated rendering, dual RTSP camera streaming via FFmpeg/mediamtx, and MAVLink drone control — including every obstacle encountered and how it was solved.
