Depends on your budget and requirements. I built a very cheap system many
year ago on the advice of others by mounting a cage on a pivot so it could
tip one way or the other, just enough to activate a microswitch. The tilt
was perhaps a tenth of an inch at the ends. This was enough for comparative
measurements in what we were doing. Also works well as a measure of
conditioned avoidance in shock cages.
