Sense Hat

[abarrow]

I think the interesting challenge here is going to be placement of the PI with the sense hat. Others have reported that their magnetometers were pretty sensitive to nearby metal objects, pretty much the same as the issues you have in installing a conventional compass. So, that said, where would you put a separate PI in a place that had minimal metal nearby, but also in a position where the LED display is obvious? One thought might be on your cabin roof, so you basically look up at it.

So, in that case, what about an arrow that points to the nearest AIS target?
