Raymarine Rudder Sensor.

[kashurst]

plastics and arm are identical to my old CETREK one which I now "upgraded" to NMEA2000 by feeding the three cables to an arduino and writing probably 40lines of code.
Damn, should sell it for 300quid then!

I am going to sort myself out and get one of these arduinos - how tricky was the NMEA 2000 bit ?

Well done OG on fixing the sensor, Doing repairs like this can be very handy in the summer when getting anything can be tricky.

I had a Dometic Aircon controller go doo-lally few years ago in August, 34 degrees C. It could not read the room temperature correctly.
No idea where to get Dometic spares and more importantly how long would it take to get a new control module in Spain in August.
No idea where to buy electronic components in Spain so went to the local chinese "we sell anything shop" near the marina and bought two different designs of electronic thermometers for 5 euros. Took them apart and removed the temperature sensors - got lucky found an equivalent . Soldered it in to the Dometic controller. Aircon restored.
Necessity is the mother of invention.

not tricky at all, others before you have done the tricky bits, now it's just surfing along
serious, if you think about getting into that, drop me a note.
for starters, get some powerful ones (teensy 3.5 or 3.6 or else Due, don't got Mega or slower ones, of course don't touch an uno!)
You'll also need a couple of cheap chips that will do the CAN conversion to NMEA2000 as well as sockets/cables et al.
Then you go into github and get the libs off Timo
I can also sent you over my code (crappy programwise, but does work!) to study if you want.

cheers

Well I just got lucky. The mobile technician who visits our club has given me a s/h rudder reference unit. Not seen it yet but I think it will be Raymarine. I have a tiller installation with a Raymarine S1 autohelm unit. I shall cut into the fibreglass tube which is glassed between underdeck & hull which houses my rudderstock & will devise a suitable mechanical installation. Our friendly technician will then connect to my electronics which is 100% Raymarine.

BEFORE you install...... check with a multi meter. Two of the wires will show a variation in the resistance as you swivel arm to and fro. If no change in resistance the little device inside is knackered. .
