Custom parts and enclosures

Piezo crystal

The X on the back shows you where to attach the piezo, and the lines off to the side show where the cable should go. It should come out 50x50mm.

Schematics

Piezo soldering

If you have a stereo cable, solder both audio lines to the center pad, and the ground wire to the outer disk. The piezo may have another solder pad in the center, which is interchangeable with the other one.
