Step 1: What You Need

Okay, here is what you will need:

1. 2 strips of sheet metal
2. a red wire and a black one
3. 9V battery
4. rubber bands
5. small square of cardboard
6. 6VDC Mini Buzzer (like three buck from radio shack)
7. Duct Tape
8. Thumbtack or somthin else with a small sharp point(not pictured)

Step 2: The Base

Cut the cardboard in half. Use one half to cut out a small strip of cardboard that is the same width of the smaller peice of metal, but smaller in length.

poke a hole using the thumbtack in the end of the smaller peice of metal.

tape the strip of cardboard to the bottom of the metal peice, then twist the black wire through the hole in the matal so it stays. tape it to one of the half peice of cardboard.

Step 3: The Button

Now for the button.

poke the hole and thread the black wire leading to the buzzer through the longer metal peice.

bend it into the shape below. tape the other half of the cardboard to the top.

Step 4: Base+Button

Now, glue the button onto the base so that the metal peices are a hair's breadth apart.

the picture below might help.

note*: i messed up at first in the picture: the red wire on the left should be black.

Step 5: The Power Source

now you have to attach the black wire that is from the base to the battery

then attach the red wire you havent used yet to the battery!

when attaching wires to the battery, first make sure that the red wire is on the smaller hole sticking out of the top of the battery(positive side) and the black one is on the bigger hole(the negative side)

you might have to wrap rubber bands around it so the wires are securely connected!

Step 6: The Final Connection!

twist to gether the red wire from the battery and the red wire from the buzzer! the finished product should look like so:

Step 7: Installation!!!!

Now it's time to install the doorbell! Just put the button part on the front of the door, and put the battery and the buzzer on the side of the door facing your room!

you should duct tape the wires to the door like I did

The first picture is of the outside of the door, the second is the inside.

Step 8: All Done!!!!!!

You are done with your doorbell! just add a sign and admire your handywork!

    You say it cost you three bucks, yesterday I bought a wireless door bell in what you would call WAL-MART for £1.85. Why bother going to all that trouble? Not that I want to put you down or any thing, I just think that you save yourself the trouble

    sorry, you're american aren't you. one pound eighty five is equal to two dollars and ninety four cents, you only save six cents. I guess that was a pretty pointless comment I made then.

    one wire is from the battery to the resistor to the LED one wire is from the battery to the LED this probably won't work, but it's worth a shot........(i don't know much about LEDs) you should look up on the internet how to hook up an LED to a battery, what kind of LED to use, and how many volts your battery needs to be (because you don't want to burn out your LED those things get REALLY hot.

    Wow dude, calm down. i wasn't making fun of it, i'm just saying a way that i think would make it work better.


    11 years ago on Introduction

    wow, this is an amazing idea. could be made better by soldering and putting a real button/rocker switch in the whole scheme of things.

    Actually a smart idea. I have a buzzer or two, would definitely like to try this out, but maybe put a speaker and when you press it, it would scream and that would be so funny! Nice job.

    Nicely done. I like the base idea. Obviously you can jazz this up anyway you want by adding a nicer housing and little tweaks like that, but once again it's a solid base idea.
