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 main sensor is a magnetic encoder that outputs an analog voltage in the 0-5V range, and the structure is mostly 3D printed. For my application I used … Continue reading Electronic Windvane
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
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
This is an update of an old project. Click the link to navigate to the Richmond Yacht Club's Wednesday night beercan starting line. It uses your phone's GPS info and system clock. To make this work: You need to browse the link below on a smart phone with a GPS. The link must be … Continue reading Start timer
If you're looking for my old site, sorry it got hacked and had to be put down. You can email me (mholden at csum dot edu) if you are trying to find something specific.
