"DO IT YOURSELF" ENTRY --- PURPOSE: To adapt a device or toy for switch use. To make the device, cut the speaker wire to desired length (nine to twelve inches)and prepare the ends by separating and stripping one-forth inch of insulation off of wire. Next, prepare two gold circles/disks. Remove posts and file smooth. Solder the conductors at one end of the wire to the disks, soldering one conductor to each disk. Be sure to bring the plastic insulation right up to the edge of the disk, but not onto it. Keep the solder and the wire flush with the disk and close to the edge. Lay two layers of double-stick tape across the bare side of one of the disks. Each piece should extend past the edge of the disk and should have no wrinkles. Stick the untaped disk (unsoldered side) onto the taped disk (unsoldered side) so that the wires are aligned (coming off in the same direction). Trim excess tape with scissors leaving a one-sixteenth-inch rim all the way around the disks. Slip the jack's plastic cover over the other end of the wire (check cover orientation). Twist wire ends, thread the wire ends through the hole at the base of jack and connect conductor wire with solder. Connect the other conductor wire to the other end of jack in the same manner. Screw the plastic cover back into place. Test the interrupter. TOOLS: Soldering iron, wire strippers, file, needle-nose pliers, scissors, and wire cutters. MATERIALS: Solder (rosin); sand paper; two-conductor, 24-gauge speaker wire; double-stick tape; brass or copper sheets (0.005-0.010 inch thick)or gold ear posts;1/8-inch mono two-conductor in-line phone jack.
