A smoke detector
A battery holder
A 9 volt battery and adaptor
Soldering iron and solder
Wire cutters/ strippers

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 )
