\section{Overview}}
Client wants a door alarm. Let's do a few transistors, an audio amplifier board, a magnet and magnetic reed switch, along with a light switch.

Functionality req'd:
\\
\\
Makes noise when door opened.
\\
\\
Able to be shut off with light switch.

\section{BOM}}
Any audio amplifier loud enough will work. I'm going to use this one:
\\
\\
IS31AP4088A-QFLS2-EB 
\\
\\
I think I have speakers and transistors. I'll need a magnetic reed switch and magnet. They should be black, as the door is black.
\\
\\
MS-324-3-3-0500
\\
\\
let's also try 59140-1-S-03-A,\footnote{A and F ending letters on this, A is tinned, F untinned leads} as first co. doesn't make the matched magnets...
\\
\\
and the magnet,

57140-000

A speaker, although I have plenty in my junk bin. 
AS07708PS-2-WR-R
\\
\\
That's a start.
