PTM: I mean new in that meaning, that in the mails about the accelerometer
there came many nice ingenious methods. It would be nice to see if
somebody can find a new solution to an old problem.

If we have a system that doesn't move, where we have good space around and
the result have not to be 'realtime' we could use cups... I try to make a
picture

                          o    -----drops goming down
                          o

                     \      B   /
                       \ ---- /   ---fluid in the cup
                    A    \  /
                ----------O   ------axel

When the cup B fills, the system tilts around the axel. fluid flows out of
the cup and the drops start dropping to cup A. When it fills, the system
tilts again, fluid flows out of cup A and cup B starts filling.

This system works only in stabile environment.
