MINI-TRIGGER

Parts Needed: All available from Radio Shack

1- piezo transducer part #273-073
1- 1/4" phone jack (mono) part #274-252
1- project enclosure  3x2x1 part #270-1801
double sided foam tape
1- 2x3 inch piece 1/16-1/8 rubber (you're on you're own to find this one, <grin>)

First step is to solder the piezo leads to the phone phone jack tabs. I always solder the red lead to the tip tab.

Next, drill a hole in one end of the project box for the phone jack. Assemble as shown placing the piezo in the bottom of the box with the foam tape.

I also use a small piece of the tape to secure the wires from hanging loose inside.

Screw the lid to the box (at this point you can use this to mount  to various things you would like to use as triggers), cover the lid with the rubber (I used double sided carpet tape) and you're done.

This
makes a really neat effects trigger.
