6months on and I'm happy to report that today I finished off (er, almost...) the installation and everything is now on board connected and working.
Fitting the bleeding magnet and sensor on a Lofrans Tigress windlass is a PITA and as fitted now picks some of the turns of the windlass and misses a few. So got to bring the sensor closer to the magnet on the windlass. I'll also try reducing the delay of the main loop checking for closed circuit on the sensor as I feel the 50ms was fine for tests at home passing the magnet leisurely over the sensor, but the gypsy turns v.fast and seems that the close circuit delta is way too small to be picked. Will hopefully sort it tomorrow as I'm about to leave for week or so with the boat.
Having programmed the MEGA (burnt the Due on testing...) I've now setup all sorts of other things on the same code but not installed the sensors on board as yet. Have tried them at home though and all seems to work:
have a few more I'm considering but that will be next winter projects...
All is based on the generous help received in here and the great project by Timo a Fin guy on github (https://github.com/ttlappalainen/NMEA2000)
Needless to say, if anyone needs code/ideas/help/bits I've used on all that, just shout!
I'll report in detail on the main rebuilt thread of MiToS in the mobo section of the forum
cheers

- NASA NMEA0183 windsensor to N2K (way cheaper than getting a proper N2K windsensor)
- pressure based tank level to N2K (for diesel and/or water tanks) Handy if you cannot drill a hole to fit a proper sensor from the top of the tank
- temp for exhaust flex hose as well as seawater temp at the elbow just before mixing with exhaust gasses, again to N2K
- old analogue CETREK rudder sensor to N2K
have a few more I'm considering but that will be next winter projects...
