Introduction: 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.

Step 1: Step 1: What You Need

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

Step 2: Step 2: Start

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

Step 3: Step 3: Cut

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

Step 4: Step 4: Solder

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 )

Step 5: Step 5: Prepare the Container

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

Step 6: Step 6: Glue

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

With the smoke chamber is there any chance of the radioactive materials which is Americium-238 (i think) escaping?

It's not dangerous at all, there is so little, it is far less then the radiation you get everyday from walking around. It is also enclosed so well you could swallow it and not get any effects from it. Your safe from turning into a mutant! Go Mr. Bean!!!!

it needs a time delay so you can lob it into someone's room and have time to run before it goes off...
