ANTI-SLEEP DRIVING ALARM

Anti-Sleep Driving Alarm is a device that you put it behind your ear while driving and will produce some annoying high-pitched sound when your head tilts forward more than 30 degrees. It is to keep your awake when you are driving a long long way. Not a new stuff though, I remember two years ago there’s one in Japan that vibrates. It is also a good device for gamers (that play World of Snorecraft), students, security guards, late-night coders, secret underground bunker employees, convenience store nightshift, pilots to keep them awake. It is available at $15
