I have been experimenting with serializing NMEA 2000 messages in JSON and sending them out as a UDP multicast stream. Initial results seem promising. The code will be on the wiki soon ... hopefully this weekend. Next up will be some software that can make use of the data stream. The project should pick up some steam now that I have a deadline. I've entered the Annapolis to Newport Race, so I need instruments by June.
This began as a project to drive analog current loop Brookes and Gatehouse gauges with data from modern sensors.
It didn't take too long before I realized that what I really wanted was a much more powerful system for display and logging of complex performance data. I also wanted better displays than what commercial systems offered. And of course, I wanted to share whatever I came up with.
Then I saw a post on the Panbo forum asking about community interest in an Open Source NMEA to IP bridge and other homebrew marine hardware and software. So instead of just thinking about putting together a website to document my work, I decided to actually do it. This is it. There's a blog (you're reading it) and a Wiki. I think a Google Group might be useful too; and probably a GitHub repository.
