This bedroom doorbell is an easy project to build with your children.

Designed by James Schadewald

Our first run at this project was a little too complex. We tried to tap into the home’s existing doorbell wiring – a cumbersome job that involved fishing wires through conduit. It wasn’t fun. But this version is perfect. A metal container houses a 9-volt battery and wiring. This base serves as the platform for a push-button switch that we wired to a nearby low-voltage buzzer. The results are surprising. And loud. When you tire of the noise, and you will, you can reduce the buzzer’s harshness by covering it with a piece of tape.

Bedroom doorbell instructions

1. Use a drill and 12-mm twist drill bit to make a hole in the lid of the container. Position the hole as shown in the diagram.

2. Secure the container in a vice, then drill a hole in its side with a 5-mm bit. Sand or file away any rough edges left from drilling.

3. Decorate the lid with patterned duct tape, paint or decals. Remove the locknut from the switch, insert the switch into the hole in the lid and tighten the locknut on the other side.

4. Cut two 1,2-metre pieces of wire. Strip 12 mm of insulation from each end. Chuck two ends of the wires into your drill and slowly rotate it to braid the wires, leaving about 30 cm unbraided at the end.

6. Pass the other end of the braided wires through the container. Attach one wire to the push button and the other to the snap connector.

7. Cut a 15-cm piece of wire and strip 12 mm of insulation from its ends. Twist one end of the wire around the free contact on the switch and the other around the open wire on the battery snap connector. Insert a 9-volt battery into the snap connector and test your work. If the buzzer doesn’t sound, check each connection for tightness. If the buzzer works but is too loud, cover one or more of the speaker holes with tape.

Installation notes

Affix the box with adhesive strips. Use appropriate staples every 15 cm to run the buzzer wires down the wall and under the door. Mount the buzzer low on the wall on the opposite side of the door with more adhesive strips and staples.
