Building A Marine Navigational Computer With OpenCPN And Raspberry Pi3
There are, of course, many proprietary (expensive) choices available, and technology changes so that as soon as you spend money on one package deal quickly, it’s quickly obsolete or unsupported. So we spent quite a bit of your time exploring our various options and determining what we wish. We’ve Raymarine/Tacktick cellular depth, speed, and wind flow receptors onboard already, and a Standard Horizon GX2200 VHF/GPS/AIS recipient as well.
We have been using OpenCPN on our laptop computers and a touchscreen tablet for quite some time and have so been very happy with its features far. Our original plan was to have a PC in the Nav station linked to a sine-wave inverter running OpenCPN. However, when we sold Meandrous, the new owners presented us to the Raspberry Pie (RPi).
These small, inexpensive single-board computer systems were made to teach basic computer science skills in universities and developing countries, and have a myriad of applications both in and out of the sea environment. Raspian is the official operating-system for the RPi, which really is a version of Linux written for these tiny computer systems specifically.

You choose the storage space convenience of the operating-system, though they often recommend at the least an 8GB micro SD card for Rapsian, which is enough to run OpenCPN as well. Roughly how big is credit cards (without the case) or a deck of cards (with the case), the RPi requires only 2.5 amps of 5.1V, so it can simply fit on even the smallest sailboat.
Once we have a look at the capabilities of the RPi, we made a decision to change course and use a RPi to run OpenCPN and build a dedicated RPi Navigational Computer. We began with a RPi 3B Starter Kit from Amazon, which came with a case, 32GB micro Sdcard, 2.5 amp AC power cable, HDMI cable, high temperature sinks, and a microSD USB reader. The micro-SD card was preloaded with NOOBS (new out of package software) that included Raspian and other operating systems to choose from. The 32-GB storage space was a little of the overkill for our application, but it offered us plenty of storage to utilize.
When some type of computer and its own or are new you hear nothing but the fan inside the computer. A humming audio. As the the ages it starts to produce a light jingling/drumming audio that overtakes the sound of the enthusiast. Nothing serious, a few decibels only perhaps. And when the hd is old it makes a noticable really, nourish, screeching/drumming/tapping sound. This is when it is time to replace the hd.
