[sdiy] floor interface?

[Harry Bissell Jr]

Pressure mats are a loser, IMHO

They are essentially like click-dome
membrane switches.  The big problem
is if you stand on the mat... it is triggered
all the time and additional pressure
does nothing.

Good for a burglar alarm... where the first touch
is the data you need. Useless for music uses
unless maybe you want to un-mute your audio when you
walk on stage.

(I do have such a mat... used it to trigger Halloween
sounds)
