Electronic Windvane

January 6, 2021January 5, 20223 Comments

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

Ardupilot Autonomous Sailboat Simulator

This is mostly just to link the video I made. It shows how to run mission planner (ground control station) and start a simulation of an autonomous sailboat (SITL), and how to run the boat in autonomous modes, including tacking parameters and geofencing. Enjoy! https://youtu.be/kzGciG7cCBc

NMEA 0183 Speedometer

September 2, 2017December 31, 202024 Comments

I had an email request to find this project from 2010... I updated the code too! This project  takes the pulse from a paddlewheel boat speed sensor and makes an NMEA output on the serial port.  It should work with most through-hull speed transducers, and also with windspeed transducers too.  The NMEA stream comes from the … Continue reading NMEA 0183 Speedometer
