Hi everyone,

I'm searching for a very simple & low cost design for a digital compass.
I've searched for parts but they're all very costly.
Please give suggestions/links for a hobbyist digital compass.

Thanks.

What is your definition of costly? The PNI V2XE is dead cheap to me.

HOw about one of these?

(Not all are compasses, some are magnetometers which just give the magnetic field readings which can be run through some math to make a compass.)

Oh....can't help you there THe few things you can get for $30 will still need a processor to do the math to turn it into NWSE compass readings since they are just magnetometers.

Well you did help there... is the hall effect sensor COM-09312 sensitive enough towards the earth's magnetic field?
I am gonna use a PIC for the input processing anyways.
