and do any under £40 (or $60 [I know that's not the conversion rate]) not do that thing where they creep back to the rest position… or is there a way to fix this (turning it on and off periodically?) What I really need to be able to do is poll it from a microcontroller to get the current orientation when I need it… will one of these http://www.analog.com/en/mems-and-sensors/imems-gyroscopes/products/index.html do that?
Unfortunately, I am interested in building a similar gadget, and I have yet to find an IC gyroscope which indicates absolute position. They all indicate rate of change, which is why the signal goes back to zero when the rotation ceases.
