A really cool gadget is Wake up. It's an anti-drowsy earpiece alarm. It's a recordable earpiece alarm that alerts you awake while you're driving, working or studying. The cool thing is it looks just like a bluetooth earpiece and you can record your own alert up to 10 seconds.
I'm a student and I'm trying to train myself to stay up later to study and I'm not very fond of coffee. At the slighted drop of my head when I doze off the alarm will sound (I recorded a clip from Shrek on mine!).
It's available on Amazon for $29 bucks.
