Actually, I have just realised I have been consistently saying AMD (Advanced Micro) when I meant Analog Devices . Worra plonker.

If you are interested in Accelerometers, they have a good article here, and the data sheet for the devices I am using is here.

Be warned - you need a very stable supply and a low noise environment for your measurements as FSD for this device is quite low. You need to carry out averaging and filtering, but I suggest you read the first article for that.
