You can make your alarm clock -really- loud by wiring in a car horn or two. Grab an automotive relay and some kind of 12 volt source that pushes enough juice to power a car horn like this guy did. http://hackaday.com/2009/09/25/140-db-alarm-clock-hack/" onclick="window.open(this.href);return false;
As for the calculator... type 011334 into it and hold it upside down and use it as a digital greeting?
