An Open Source Shipboard Computer System
March 29, 2020 No Comments Tech Hacks Jimmy Jones

We’re uncertain how many of you out there own a boat big enough to get its own incorporated computer system network, but it does not truly matter. Even if you can’t use this job personally, it’s difficult not to be impressed with the work [mgrouch] has actually put into the “Bareboat Necessities “task. From the building and construction of the hardware to the remarkable documentation, there’s plenty that even landlubbers can learn from this task.

In its fully realized kind, the onboard computer system includes numerous parts that work together to provide a wealth of valuable details to the operator.

Inside the Boat Computer system module What [mgrouch] calls the “Boat Computer”contains a Raspberry Pi 4, a dAISy AIS receiver, an RTL-SDR, a GPS receiver, serial adapters,

and the myriad of wires needed to get them all talking with each other inside a weatherproof enclosure. As you may expect, this involves running all the connections through watertight panel installs. Integrated with a suite of open source software tools, the”Boat Computer” can interfacing with NMEA sensors and hardware, get weather information straight from NOAA satellites, track ships, and obviously plot your current position on a digital chart. The computer system itself is created to stay safely below deck, while the operator communicates with it through an Argonaut M7 waterproofed HDMI touch screen situated in the cockpit.

For some individuals, that may be enough. However for those who want to do huge, [mgrouch] even more details the “Boat Entrance” device. This unit contains an LTE-equipped WiFi router running OpenWrt and all the external antennas required to turn the boat into a floating hotspot. Obviously it likewise has RJ45 jacks to connect up to the other components of the onboard system, and it even consists of an M5Stack Core with LAN module so it can display a select subset of sensing unit readings and navigational data.

If you ‘d like to do something similar on a slightly smaller sized scale, we’ve seen sailing computers that pushed all the information to a wearable display or even a

repurposed eReader.
