DIY beeping Easter egg

12 March 2018

 What We Need:

Components:

• Switch
• Beeper
• 9V connector
• Insulating tape
• Large plastic colored egg
• Battery

• Soldering iron
• Drill

 

We purchased components from Radio Shack. You can buy all the components in various stores.

How to?

1. Drill a sufficiently large hole for the switch in the egg
2. You need to drill several extra holes around the egg to allow sound to escape
3. Solder one lead from the 9v clip to one connector on the toggle and solder one lead from the beeper to the other toggle connector. The solder is needed on the toggle connections to keep that connection secure through rough handling
4. The second beeper wire can be attached directly to the remaining 9v battery lead. This creates a single switch series circuit that allows the battery to be replaced by simply removing the 9v clip and re-taping the new 9v in place. The wires can be twisted together and secured with electrical tape.
5. We secured the toggle switch to the hole drilled in the long end of the egg using the nut and washers supplied with the switch. Tight but not so tight the egg cracks.
6. The piezo beeper must be secured to the 9v with electrical tape. Make sure that you attach the battery to the beeper with the long ends of the beeper running the length of the battery so the egg will close securely. You might want to put a small piece of tape on the outside of the egg holding the two halves together.
