A small but really loud siren. This will need a 775 DC motor, I recommend using one rated around (or higher than) 8000 RPM. The screws needed are 8 10-24 screws and 2 screws for a 775 motor. You may need to "clean up" the holes with a drill to make everything fit. Also, I highly recommend wearing hearing protection when near this thing, it is very loud and could probably cause hearing damage.
