I Am trying to connect an accelerometer, gyro, whatever to a dental drill so I can observe the position of the drills on a monitor. Save position of one and have the ability to make the second parallel to the first
What you want to do is nearly impossible (if I understand you correctly).
I think you are trying to use accelerometers and gyros to estimate the position of the drill, suppose you accelerometer can measure up to 2g (not much , easily exceeded by rapid hand movement) and has an offset error of 0.1% (very good for a low cost accelerometer), that's equivalent to an acceleration error of 0.02 m/s.
After 60 seconds the error in calculated displacement will be (0.02 * 60^2)/2 = 36m (yes thirty six meters !!).
Of course in real life you get these errors in more dimensions with additional errors from the gyros.
The reason that games use vision/ir etc to estimate position of players is that you can't do it cheaply with just accelerometers and gyros.
I thought he just wanted to plot out the motions of his drill... If he wants to save the exact position of his drill he'd be better off mounting a camera snaping pictures to compare its position.
