Mr. Gibbs is a powerful, inexpensive, and extensible tactical sailing computer. After getting fed up with the expensive commercial offerings (Velocitek, TackTick, RockBox), Brook Patten decided to build his own and make it open source.
The goal of this project is to build a system which will meet or exceed the functionality of commercially available tactical sailing compass/gps units, with inexpensive, easy to acquire commodity hardware. A minimum configuration of the Mr. Gibbs unit and a Pebble watch will cost less than $150 to build.
The latest iteration runs on a Raspberry Pi Zero with Jessie Lite. It uses bluez5 for better bluetooth support (including BLE), and it uses 2 18650s for power. It also includes a BLE wind vane which is self powered and mounts to the mast with no wires.
