INSTRUCTABLES PRANK BOX | JAMECO PART NO. 2169504

Step 8: Heat Shrink Electrical Connections

Step 9: Insert Batteries Insert D batteries in the battery holder and using four more zip ties, firmly band all of the batteries in place both vertically and horizontally.

Step 10: Glue Relay Plug in the 9V battery and epoxy the battery holder in place. Hot glue the relay to the mounting bracket in the free space next to the battery.

Step 11: Bundle Everything Together with Zip Ties If possible, zip tie this bundle to the battery pack to prevent it from interfering with the bell.

Step 12: Glue it together Test to make sure the bell turns on and off. Seal the box shut and apply wood glue to all of the joints and firmly clamp it together.

Step 13: Use a Belt Sander to Round the Edges

Step 14: Make a Sign Laser cut the sign using the template from Step 2. If you don't have a laser cutter, you can use a service like Ponoko, or do this the old-fashioned way with saws, stencils and Exacto blades.

Step 15: Sand and Stain (Optional) Sand the box and wipe it clean. You can put on a coat of stain in a singular direction. When it has dried, lightly sand again and apply the stain in the opposite direction. Lightly sand once more and lay one last coat of stain in the initial direction.

Step 16: Affix the Sign

Step 17: Project Complete It is simply good to distance yourself from the person who engages the box. Remember to be a good southern neighbor and eventually tell them how to turn it off. However, I think 20 - 30 minutes is about a fair amount of time to wait before telling them about the magnet triggered reed switch on the side of the box. Also, when triggering the reed switch, make sure the key is not inserted in the lock and turned. If it is, this will not work.
