Are you the type of person who really hates waking up and can sleep through any alarm? TechBuilder shows you how to build an alarm clock that uses a car horn to wake you up every day.
The project rewires an old alarm cock through a car horn for an intensely loud alarm that will certainly wake up even the soundest sleeper. You'll need basic soldering skills to build it, but it's not terribly hard all things considered.
