    If I follow this correctly, why would you even need a motor ?  Picture a
    fork with only two tines.  Now a shaft horizontally between the two tines
    on bearings. A small lever attached to the shaft HANGING down vertically
    between the two tines.

"hanging" requires Gravity, or a mercury switch would be sufficient.
In essence, I'm looking for the simplest, cheapest equivilent of a mercury
switch that will detect an attitude change in free fall.
