Let's me try...I would like to know if there is some possibile sound alarm sistem with little consumption of energy, that is stand alone and is sufficent to wake up a person (anchor alarm)
OT: Pinguino, in your opinion it's better to use the vnc viewer in the tablet or taking datos from wifi and use opcpn in the tablet?
I'm waiting for Moitessier hut, and my configuration is going to be
1. RSPi3 with 7inch screen in the navigation table inside the boat (with AIS) performing opencpn
2. Tablet in the rudder with navionics app and when i need with vnc viewer for ais (this what i suppose)
There some other simpler solution? Navionic app can take datos from OP?
Thank you

didn't quite understand what exactly you wanted to know.
But....
In the case of AIS alarms, these generate an alarm sound in openCpn that can be selected at will. An amplified speaker connected to the Rpi's sound output is required for this sound to be heard. The same loudspeaker will sound the anchor alarms and all the others.
But if you talk about making it sound on the tablet, the easiest way is to use the Android version of OpenCpn feeding on the NMEA0183 data that you will receive via wifi from the Rpi. I use it with my rugged phone at the tiller and it's going very well.
If you're talking about something more sophisticated, you already have the idea of Jim321 going one step further.
What exactly do you want?
