Andy,

have a look at these sides for some homebuilt magnetometers :

maybe there is something usefull for you.

I have been given a small compass module that, apart from magnetic heading,
gives a serial digital high resolution output of X and Y components of the
Earths magnetic field.  Added a simple PIC + S/W to give the outputs in text
formatted RS232 for connection to a PC.  Whilst idly thinking of something
to do with this (apart from a remote compass on my antenna)  I wondered
about a 2 axis magnetometer monitoring for solar storms etc.

Does anyone on this reflector (Alan ?) know what sort of magnetic field
changes are a precursor to magnetic storms, and what sort of sampling
interval it is worth averaging over to automatically alert on these.  I
could easily log X / Y data to disc at a regular interval, write an alerting
function etc etc.  if there is any worthwhile research advantage in doing
so.   Otherwise the module will be relegated to being used on 10GHz portable
operations, for aiming my dish remotely.
