"DO IT YOURSELF" ENTRY --- PURPOSE: To enable individuals who cannot successfully comprehend and/or use augmentative displays for communication to communicate. With the use of this switch display, a user receives auditory reinforcement, while alerting another person to the attempt to communicate. The adaptation is an object display box with a switch under its cover. The box mounts to a wall with industrial Velcro. The device is then connected to a Switch Module. The Switch Module is a self-contained recorder-talker that accepts one to four switches. (An eight-switch module is also available.) To make this device, drill a hole in one end of the experimenter box and thread speaker wire through the hole. (The size of experimenter or project box should be dictated by the size of the object to be placed in it.) Next, solder wire to the switch. Mount the switch on opposite end of box, near the top. Be sure it is high enough that a light touch of the cover will activate it but low enough to avoid touching the cover when not activated. Solder the phone plug on the unfinished end of the speaker wire. Mount the object in box using foam mounting tape or hot glue. Fit the cover and punch or drill holes for screws and attach. DIMENSIONS: The box should be at least 6.25 x 3.75 inches. MATERIALS: One Switch Module (from Toys for Special Children); one laminating pouch (10 MIL), laminated and cut to size or a cut-to-size Plexiglas cover; one experimenter box; one submini lever switch; one two-conductor 1/8-inch phone plug; two to three feet of two-conductor speaker wire TOOLS: Solder and soldering iron, drill, and foam tape or hot glue and glue gun.
