Bill Ballard has taken a Raspberry Pi, a Pimoroni Scroll pHAT and an Adafruit Ultimate GPS board and created a trip recorder for when he’s out on his boat. The Scroll pHAT displays the current speed in knots whilst the Raspberry Pi outputs location readings from the GPS board to a file. The file is later imported into a Mathematica program and the route that was taken is plotted. Read more on The MagPi website and see his code on GitHub.
