This is a weird one. A means of turning on an effects pedal/circuit via.....gravity? The circuit utilizes mercury/tilt switches in place of the typical mechanical throw switch, and takes place of the 3PDT footswitch in most pedals. When the entire circuit board is parallel to the earth or flipped 180 degrees on its 'x' axis (upside down), the secondary circuit will either be ON w/LED or in TRUE BYPASS. I've used mercury switches in the past to make SPDT, DPDT, and 3PDT switches using 2, 4, and 6 individual mercury switches respectively. I doubt many people, if any, will build this as its simply not very useful. Just a cool project.
