Instructions
Place the board on a flat surface with the short edges to the right and left and the long edges to the top and bottom.
Tap the 3-inch nail into the board about 4 inches from the right side and centered between the top and bottom of the board. Tap in the nail just enough so that the nail stands securely.
Measure 5 inches from the end of a coil of insulated wire and begin wrapping the wire around the nail, working from the base of the nail towards the top of the nail. Wrap the wire 100 times around the nail, then measure out 6 inches from the last coil around the nail and cut the wire.
Measure 1.5 inches from one end of the 7-inch strip of metal and make a 90-degree bend, creating an L shape. Attach the short leg of the "L" to the board between the nail and the right edge of the board with a small screw, about 2 inches from the edge and centered between the top and bottom of the board.
Bend the long leg of the "L" at a 90-degree angle, so that the edge of the metal hovers just over the head of the nail containing the coiled wire. The metal and the head of the nail should not quite touch.
Screw in a screw in the top-right corner of the board and one in the bottom-left corner of the board, leaving the neck of the screws exposed.
Place the battery holder alongside the top edge of the board, with the red wire trailing to the left and the black wire trailing to the right.
Wrap the end of the black wire and the wire from the top of the nail containing the coil around the neck of the screw in the top-right corner of the board. Ensure that the wire tips are touching and tighten the screw to secure the wires.
Wrap the end of the wire from the bottom of the nail containing the coil around the neck of the screw in the bottom-left corner of the board. Ensure that the wire tips are touching and tighten the screw to secure the wires.
Measure 1 inch from one end of the 2-inch strip of metal at a 90-degree angle, creating an L shape. Attach one leg of the "L" to the top-left corner of the board, so that one leg of the "L" is vertical, the edge of the leg parallel to the left edge of the board.
Bolt the 3.5-inch strip of metal to the vertical leg at the left edge of the board, so that the strip of metal is also vertical and parallels the left edge of the board. The tip of the strip of metal should sit next to the screw at the bottom-left corner of the board. The strip of metal and the screw should be about 1/4 inch apart. This is the paddle.
Insert the batteries into the battery holder, following the positive and negative indicators. Tap the paddle so that it touches the nail at the bottom-left corner of the board to create a buzzing sound.
