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

Parts:

1.5-3v buzzer

wire

doorbell

AA or AAA 2-battery holder


Tools:

soldering iron

solder

screwdriver

screws

batteries

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

Here is a video  of me using my doorbell. I hope you enjoyed this instructable. please rate and comment. thanks for viewing :)


you might add the um66 melody doorbell like i did for my front door :)
can anyone give me really cheap ideas for a security thing (just because im a geek dont mean im not a builder and it dont mean om not nice so dont cause me trouble)
go to thinkgeek.com they have a couple of cheap doorbells <br>
buy,borrow or steal a GUN---good security
I just wanted to point out that you got the wiring all wrong. Although it will work either way, the way to do this is to put the doorbell switch in between the positive (RED) wires thus controlling the positive flow of electrons. The way you have it done here constantly has a flow of power to the buzzer, whereas the power only hits the buzzer when the button is pushed if the switch is between the positive wires.
I realized that too after i finished putting it together, but since its only a 3v circuit i didn't really bother to fix it
It's a good project for a cheap wired doorbell.Though it can satisfy our sense of achievement of DIY,but for a higher security purpose,a <a href="http://www.espow.com/wholesale-security-surveillance-alarm-systems.html">video door phone</a> is necessary.
I made a almost identiv=cal thing! check out my instructable :D https://www.instructables.com/id/A-Fast-Simple-Doorbell-For-Your-Bedroom/
i might make something like that for my room but i would add a couple bright blue or red LEDs to it so when i am playing my music loud i can see when some body rings it and maybe i could have a door bell on my door and one that is down stairs so when my mom want me to come down she just has to press it. good job and it can also be moddified. zippy
I was thinking the same thing but I'm not sure where i would mount them yet
&nbsp;I loved doing these when I was a kid! &nbsp;Simple circuits are fun for any age.
me too, i'm only 15, but i've been messing around with electronics since i was about 7.&nbsp; i figured this would be great for people new to soldering or electronics
&nbsp;It is great for beginners!
thanks i thought so too :)
&nbsp;Genius!
thanks :D
