Annoying Beep Maker

In this instructable i will show you how to make a pocket sized device that beeps rapidly, mde out of a smoke detector.

You will need:
A smoke detector
A battery holder
A 9 volt battery and adaptor
Wire
A switch
Tools:
Soldering iron and solder
Wire cutters/ strippers
Metal shears
Hot glue gun and glue

Start by taking apart the somke detector and removing the circuit.

Now cut away all of the area and the aluminum casing in the plastic, keep the wires and the IC.

Now solder a wire to the tall wire, solder one switch lead to that, and solder a wire from the IC to the other switch post. Don't ask me how i figured this out, i just stumbled upon it. Now desolder the 9 volt clips, remember wich is wich. Solder the corresponding wires from the 9 volt adaptor.




Hint: ( The connectors will be opposite of the 9 volt polarity )

Now place the circuit in the box, cut a hole where the "speaker" will be. Also cut a hole for the switch.

Now glue the switch in place, then plug in the 9 vot battery.

Congrats! Your done! Here is a video of the Beeper in action, the sound is a bit distorted, its a lot higher and louder.
