Questions about waking up on time seem to come up in Life Hacks circles pretty often. I've wanted to try one of those "Zen Alarm Clocks" that wakes you up with a series of chimes of increasing frequencies, but they're quite expensive, so I made a virtual one. It's a sound file that you can either schedule your computer to play (if you can hear it from bed), or put on a CD or tape for use in a clock radio or whatever. Share and enjoy, and give me feedback if you'd like.
