How about using an free-moving arm in a plane parallel to the "floor"? (i.e. - like an analog wall clock placed face-up on a table) If the arm had a some weight and a wheel on one end and a shaft for a fulcrum on the other end, the position of the (...) (23 years ago, 21-May-02, to lugnet.robotics)

| | super cheap tilt sensor?

I was wondering if anyone knew of any extremely cheap and easy way of making a tilt sensor - that preferably doesn't involve transistors, etc. The best I can come up with are some mercury tilt switches with some resistors - so that a single input (...) (23 years ago, 21-May-02, to lugnet.robotics)
