I'm back in good old Numptyland now. Phew!
Geeks rule. Ha ha I squealed his brain.
I designed and built an electronic compass, yaw, roll and pitch sensor head using PICs and similar sensors (and a few more) around 1998/9 which fed into a sophisticated micro that actually crunched the numbers (which I didn't program). The application was for light aircraft and we only had to achieve an accuracy, resolution and repeatability of 1 degree in each axis. Accuracy and resolution were not a problem, but the repeatability over a wide range of conditions was the killer.
I would certainly say stick with measuring one plane of movement (such as the linked device) for an easier life! Having said that we did achieve the spec. with quite a bit to spare, but it really was prohibitively expensive for applications such as surveying (I think that the aircraft kit was being sold for $5000)
If I ever had the time I'm sure that I could do something cheaper now, but I would want 0.5 degree specs. and for it to have a distance measuring laser pointer.
Up with the geeks! And yes, I am a rocket scientist (sort of)
