Build a Raspberry Pi chartplotter for your boat

Earlier this year, James Conger built a chartplotter for his boat using a Raspberry Pi. Here he is with a detailed explanation of how everything works:

Building your own Chartplotter with a Raspberry Pi and OpenCPN

Provides an overview of the hardware and software needed to put together a home-made Chartplotter with its own GPS and AIS receiver. Cost for this project was about $350 US in 2019.

The entire build cost approximately $350. It incorporates a Raspberry Pi 3 Model B+, dAISy AIS receiver HAT, USB GPS module, and touchscreen display, all hooked up to his boat.

Perfect for navigating the often foggy San Francisco Bay, the chartplotter allows James to track the position, speed, and direction of major vessels in the area, superimposed over high-quality NOAA nautical charts.
