• 1 piece lightweight scrap wood, about ¼-inch thick
• 2 feet low-wattage wire, 18- to 22-gauge
• 1 Adafruit ADA783 coin-cell
• 2 3-volt coin-cell batteries
• 1 white
• 1 mini clothespin
• Miter saw, jigsaw, or handsaw
• Coping saw
• Hot-glue gun
• Soldering gun
Crosscut the piece of ¼-inch wood to produce a 3-inch by 1-inch wooden base. Mark the curved sides with a pencil, and use a coping saw or jigsaw to cut the curves.
Use a 3⁄32-inch twist drill bit to make the two holes spaced about ½ inch apart near the top of the base.
Center the battery pack approximately ¼ inch up from the base's bottom edge. Use a hot-glue gun to attach the battery pack to the base.
Cut the wires coming from the battery pack to 1 inch long and strip ¼ inch of insulation from the ends. Cut two 12-inch pieces of the low-wattage wire and strip the ends. Solder the battery-pack wires to the low-wattage wires, and wrap the joint with electrical tape once it cools.
Flip the base so the battery pack is facing down. Use wood glue to attach the clothespin to the top of the base edge.
Run the low-wattage wire from the bottom of the battery pack under the base, up to the clothespin, and through the two holes. Pull the wires through the holes, then twist them together to form the neck of the light.
Use a 3/32-inch bit to bore two holes in the Easter egg. Feed the wires from the diode through these holes. With the battery pack switched to the On position, hold the two diode wires to the electrical leads to determine the correct orientation to make the diode illuminate. When you've got it right, solder the wires to the LED leads.
