I thought I would share this with you guys. I'm sure I'm not alone when I say "I never knew a gyroscope was so microscopic" in terms of how it works. Reading this little page gave me a different look on how they work. The site is the iPhones motion sensor taken into a microscope, nice pictures :)

Anyone else here learned anything new from this site? I never knew how complex these were, especially at a microscopic level...

hm..
i was explaining to someone yesterday that they were a little cantilever with capacitor plates on either side, measuring the tiny change in differential capacitance as the thing moved.

amazing that a tenth of an atomic diameter movement can be detected easily, with a $2 chip.
