Introduction: DIY Doorbell for Your Room
I found an old doorbell in the garage and decided to make my own personal doorbell for my room. this is a really easy project, and i took me like 5-10 minutes to do it.
Step 1: Materials
AA or AAA 2-battery holder
Step 2: The Doorbell
Take apart the doorbell. i only had 2 screws on the back that I had to unscrew. then take out the circuit board (optional, just easier for soldering). I used alligator clips to find which 2 points would work. When you find out what points work, then solder a wire to each spot. Now just put the doorbell back together.
Step 3: Complete the Circuit
Now solder the negative wire from the buzzer to the negative wire from the battery pack. then solder the positive wire from the buzzer to a wire coming from the doorbell and the positive wire from the battery pack to the other wire from the doorbell. I used heatshrink tubing to cover up the wires. Now just put in the batteries and test it out to make sure it works.
NOTE: I wired the wires backwards. You should hook up the red wires to the switch and not the black like i did.
Step 4: Install It
I screwed the doorbell to the front of my door, then ran the wires to the back and screwed the battery back and buzzer in place. Finally I put electrical tape over the wires to make it look a little nicer and put batteries in the holder. (Later on I drilled a hole behind the doorbell and threaded the wire through it to the back to make it look better).
Step 5: Video
