Guide to Repurposing Old Phones into Alarm Devices

To repurpose old phones into alarm devices, you'll need simple items like:

- A phone with physical buttons.

- Bolt belt.

- Wooden rod.

- Skewer stick.

- Coiling wire.

- Glue gun for wax.

* How to Repurpose Old Phones into Alarm Devices.

Step 1: Use a glue gun to spray adhesive onto one end of a wooden stick as shown below.

Step 2: Then, attach a bolt belt to the adhesive-coated end of the wooden stick.

You'll need to ensure that this bolt belt stands upright at a 90-degree angle to the wooden stick.

Step 3: Next, to repurpose the old phone into an alarm device, position this wooden stick so that the bolt belt end makes contact with the surface of the old phone's keypad as shown below.

Step 4: You'll then need to secure this wooden stick by tightly wrapping it with adhesive tape.

You also need to make sure that this wooden stick is securely fixed.

Step 5: In the next step, we'll cut a small piece from the prepared skewer stick.

Step 6: We'll use coiled wire to tie this small piece of skewer stick.

Step 7: After tying the small piece of skewer stick with coiled wire, we'll insert it between the wooden stick and the phone as shown below.

Step 8: To repurpose the old phone into an alarm device, you'll pull the small piece of skewer stick through the coiled wire.

Note: At this point on the old phone, you've set up speed dial with the number that the bolt belt will touch when pulling the skewer stick.

Step 9: Finally, you'll secure the old phone we've worked on to the door, along with coiled wire fixed to one end of the door.
