Diy Chiller

hi am from singapore here, pardon my english if they are lousy. I always wanted to diy a mini chiller for my room and thus wala... made a peltier unit and stuck it into a styrofoam box... hot glued a thermometer onto the back. feel free to drop some comment.. recently added some leds inside so that when the box is open it will light up inside. so far the lowest temperature it can get is 18'c in under 10 mins... nice..
