5. ATTACH THE SPEAKERS AND CIRCUIT TO THE FORM
5a. On the form, pierce a hole in the
center of the back triangle (the one
without the fold). Use a drill if you
have one. Next, using hot glue, attach
the speakers in place. Position the
circuit on the front triangle and glue
it securely to the mat board. Slide
the plug-wire piece through the
5b. Cut two 1" pieces of heat-shrink tubing. Slip the heat-shrink over the ground wire of the plug. Wrap the
ground wire of the plug to the ground wire coming from the circuit. Solder and shrink the tubing. Repeat
for the plug’s 2 input wires, attaching both input wires from the plug to the corresponding wire on the trimpot.
5c. Locate an ideal position for the 9V battery on the top triangle of the form. Using a piece of sticky hook
and loop tape, attach the battery to the top triangle. Using hot glue, adhere corresponding strips of hook
and loop on opposite ends of the inside of the form and the top of the fold.
5d. Connect a 9V battery to the
battery connector and plug in your
portable music player.
5e. Determine the angle at which the
tilt switch switches on. Hot-glue the
tilt switch in the appropriate position
so that it’s “on” when the front of
the speaker is facing forward (when
you can see both speakers) and “off”
when the front speaker is facing down
(when you can only see one speaker).
