http://hotchk155.blogspot.com/2011/10/musical-ping-pong-tables-and.html A project in progress to (eventually) work out the coordinates of a knock on a table top in 2 dimensions using 3 contact sensors and time-difference-of-arrival and to use that to trigger different sounds via MIDI. This test is with just 2 sensors and is only working in 1 dimension but shows promise. The sensors are simple piezo disks but by trial and error I arrived at the pre-amp/pulse conditioning circuit shown here.
