Picture of How to Add Custom Ringtones to a Wireless Doorbell

Most doorbells just make a simple generic tone. But I thought that it would be fun to modify a door bell so that it has a customizable ringtone. That way you can set it to play music or custom greetings. You could make it to scream on Halloween and play carols at Christmas. So in this project, I am going to share with you how to add a simple recording module to a wireless doorbell.

Wireless Doorbell (and required batteries)
9V recording module (RadioShack Model: 276-1323)
9 volt battery

Wire strippers
Wire Cutters
Soldering Iron and Solder (optional)
Hot glue and hot glue gun (optional)

Step 2: Background: How the Wireless Doorbell Receiver Works

Picture of Background: How the Wireless Doorbell Receiver Works
The circuit of the wireless receiver is divided into five main parts.

1. The Radio Receiver: This section filters and amplifies the incoming radio signal.
2. The Decoder Array: This array of jumpers is used to set either the device's tuning frequency or the security code on the IC chip. This helps to prevent it from interfering with other nearby wireless devices.
3. The IC Chip: The IC Chip monitors the incoming signal and detects when the button on the transmitter has been pressed. When the signal is detected, it sends a tone to the speaker.
4. The Volume Control: This is a simple transistor amplifier that uses a variable resistor to set the speaker volume.
5. The Speaker: The speaker is a plain 0.25W speaker. It is wired between the positive supply voltage and the volume control transistor.

Hi, I have a question about this. What 2 points on the circuit board would you jumper to make this doorbell ring manually? I do have the wireless doorbell button, but I need to find a way to "manually" jumper this circuit board and make the chime go off without the wireless button. I'm doing a different project that requires the chime to be triggered with a "closed" signal sent thru 2 wires directly to the circuit board, from one of my home automation devices (an I/O Linc). Basically all I need to do is find a way to manually jumper the board to make the chime to go off. Thanks in advance!

Each board is a little different. Send me a close up picture of both sides of the board on the doorbell reciever.

I love this idea, great instructable! I did have a quick question, I'm working on transforming my front door from what it is now to look like the blue phone box from Doctor Who. Something like this would be perfect so that I could record the TARDIS sound and have it play when someone rings the bell. My only question is, how could I go about doing that so it sounds loud and clear? Either way I'll try your instructable and let you know how it goes. Can't believe there aren't more customize-able ones out there. Thanks again!
There are a few commercial version available but thet are a little more expensive,

Congratulations on being a finalist in the DIY Audio Contest!! Good luck to you!
You are a thief this project site?
That was a little embarrassing... :P
I see that you have come across my MakeProjects account. I am an active member of both communities and I post all of my projects to both websites. I appreciate your concern.

i liked th wooden box....i had the same doorbell and never thought to close it in a neat.

This is a cool How to. The doorbell with the wood on the sides is a Heath Zenith 8-Note Melody Wireless Doorbell. I have one and that's why this instructable caught my eye.

Could you give more details on the original doorbell? I've had a devil of a time finding a good one...

Unfortunately, I have no idea what brands or models that I used. I moved into a new house and there were two wireless doorbells there. The circuits were really similar in terms of how they activated the buzzer. So I assume that it is a pretty common design. The setup that I used will work as long as the ringer is using a transistor to short the negative terminal of the speaker to ground.

Great idea, and really so simple. Now add an amp to drive a larger speaker.
Can one just "jumper" the original speaker wiring to make the recorder play at a remote (additional) location (like the basement or laundry room)?
I used a wireless doorbell, so you are free to put it anywhere. But it would only work for one location. If you wanted to add a second ringer, you would need to get an additional receiver and recording module and then match the encoding combination on the receiver board.

Next step: RFID. Each family member gets a different ringtone, so you know who's at the door without a peephole! :-)
This is great.
