Here’s an interesting alarmclock I heard about and been wanting to test for a while:

aXbo uses a wrist monitor to detect the best time to wake you up. You set a period of half and hour and the wrist monitor decides when your sleep is in the lightest stages in that period, using some soft sounds to wake you up at the right moment.
If works as promised, this could be the difference between waking up feeling you hadn’t sleep at all, or waking up all renewed.

Check more info at the official aXbo website.
