Building an embedded device for sailboat racing: power and packaging

A polycarbonate plastic enclosure for the device, with an internal aluminum PCB-mounting board

With the software running on the Raspberry Pi and touchscreen in a “bench test” format on top of my desk, it was time to start thinking about how I would actually package this up into a complete device that I could install on the boat. It needed to be waterproof, powered by the boat’s battery bank, and ideally no larger than necessary.
