I built N4N1 to learn the details of the ardupilot sailboat firmware. I have had a few student groups building similar vessels at work, and thought it would be worthwhile to go through the exercise myself. Plus I had a boat gathering dust that needed a job. N4N1 uses the ardupilot sailboat firmware on a … Continue reading N4N1 the Autonomous Sailboat
This project documents how to make a windvane to sense the wind direction. It was designed for an autonomous sailboat but could be used in other applications. The structure is mostly 3D printed and uses a gopro mount to attach to the hull. The main sensor is a magnetic encoder that outputs an analog voltage … Continue reading Electronic Windvane
Using ardupilot with a telemetry radio to send data to your groundstation is the easiest setup and works very well. It is limited by RF range, which is determined by the radio power (more power gives more range but costs more and may require a ham radio license). The range also depends on good line-of-sight … Continue reading Ardupilot with Mobile Data Telemetry
