Note: of course this requires your computer being in the same room that you are sleeping in.
Using Kuku Klok
Once you load the page, you simply set the time you'd like to wake up:
Select the sound you want (previewing it helps to test if your speaker volume is up enough)
And then click SET ALARM.
The great thing about this website is that it will work even if your internet connection goes down after setting the alarm. (In fact you can use this site offline by doing File \ Save As \ HTML Complete).
Disable Other Windows Sounds
One problem you might notice is that Windows will sometimes make other sounds during the night which might interrupt your sleep… I recommend going to Control Panel \ Sounds and then setting the Sound Scheme to "No Sounds" on the Sounds tab (works the same in XP or Vista).
Use the Kuku Klok at kukuklok.com
