Do it yourself Boat Monitoring System

Isn’t it neat that a lot of boaters gleefully invent stuff to improve their vessels? A fairly extreme example is one Roger Jones who put together his own elaborate boat monitoring system, wrote the necessary software too, and then created a site where anyone can download this software for free and read Roger’s well written instructions about how to assemble the hardware from off-the-shelf parts. Roger’s screen shots indicate that Version 2, currently in “beta”, can not only mind batteries, AC power, pumps, lights, and NMEA 0183 nav data, but can also display weather buoy data (from where I don’t know) and video. Nice work, Roger! (By the way, I learned about this because Roger posted a message on our Electronics Forum at PMY).
