Step 5Enhancements
This is a very simple device, and is open to many easy modifications and enhancements. One such enhancement would be to add an on/off switch. You might also consider adding some sort of control that will allow you to vary the timing and delays of the beeping. Perhaps a potentiometer, or some jumper pins.
One good modification would be to find a way to increase the speakers volume. You could, for instance, drive the speaker with 2 AVR pins. Alternating which pin is on and off to provide the maximum possible voltage amplitude range to the speaker. You could also have the speaker go off at random intervals to provide maximum annoyance while making it even harder to locate.
I'll leave the details up to you, get creative and have fun!

haha, i made one but it is more expensive than this. I will probably just crank out about 5 of these and sell them to all of my friends. They will love this.
