Sigh. The pendulum works well when the vehicle's max acceleration is low enough not to disturb the reading. You can get low cost (~$5) 2 axis potentiometer joystick innards from some junk electronics houses (Edmund Scientific used to sell just the thing) and mount it upside down with a lever arm and bob attached for a 2-axis inclinometer. Cheap a/d and you are done. -Louis. -- ............................................................................ Louis L.
