AIS Collision Alarm: CPA/TCPA Alert Data Output
#5
I would like this as well. I would put the 8x8 bright LED matrix of my Sense Hat to work on AIS collision alarm.

I was also thinking about a visual alarm when a pre-programmed magnetic course (set with the on board arrow keys) deviates 25 (+/-) degrees compared to actual heading, that way the captain has an eye, when below deck, at what the steerman/autopilot is doing. A similar visual alarm for GPS signal loss. All that would require quite some creativity with Python, it's doable.

Why the LED matrix? My 15 inch LCD goes to sleep after 5 minutes. It would save power and a step or two to move the mouse to have OpenCPN back on the screen. Why not a buzzer? Because of engine noise but both visual and audible would be better.
