Easy&Cheap(no Soidering) Annoyance Beeper!

There was a sudden beep in my garage I had never heard it before so I started looking but couldn’t find the source .I didn't hear it again the whole time I searched for it but when I went to leave....BEEP! It took me 6 months to find that annoying little beep I searched high and low but for naught! Finally one day I happened to have it in my hand when it beeped and when it did I screamed like a little girl.... I was that surprised (and pleased )to find it. Turns out that beep was coming from an old smoke alarm we had out there because we had bought new ones. They start beeping intermittently when their battery is running low. I found out about this the hard way, but my embarrassing situation Is your gain because the idea hit me if it took me that long to find something so obvious...It would take somebody I deemed worthy of an annoyance ,at least  twice that long if made it smaller and  easier to Hide. MMAAAUHHHHHHHHHHHhhhh...sorry I lost it there for a sec...Now back to our evil plan!
 
What you will need:
1. An old smoke alarm
2. A small flat head screwdriver (I use a steak knife but in retrospect ....)
3. An Dying 9 volt battery (stick it your tongue for an hour.)...it work for my brother Dewey  ; P (but ... of course he's Dewey)
4. The victim...er...subject.
5. A genuine disdain for the sanity of mankind....or woman kind.

Get an old smoke alarm 

open it up to expose the innards

You will notice there are a few tabs holding the stuff inside use your screw driver to snap these off.

 On the back there are some holes that also go to tabs  use the screw driver to push these inward while gently pulling the inside from the other side this is what is holding the innards .

 you are left with this ...now just snap a 9 volt on

Now hide it ( you can do a better job hiding than I did)
Sit back and watch the fun.  :D the better you hide the harder it is for them to find and since the beep doesn't happen on a regular intervals it makes it that much harder to find Have fun!
