Firstly "Thanks to all who responded to this thread so far" Your Ideas have
been an insperation. In fact I have now concluded that I probab;y don't
actualy require an Accelerometer but a 3 DOF movment detector, I am trying
to build a small device that I can attach to my snowboard that will sound a
LOUD alarm if anybody tries to "Borrow" it without my permission. It will
have a small keypad to arm/dis-arm it and must be about the size if a
ciggarett packet. it will run of a 9V battery. I have most of the keypad
and I/P O/P code sorted so far it's based on a 16c84. So if anybody has any
ideas on motion dectection please let me know. It dosent have to be linear
just digital will do. IE motion /no motion but the sensivtivity must be
quite good.

Thanks again for all the help so far .......


Cheers Peter ............
