14x7 LED Matrix, displaying the time, day, date and temperature. 16F877 pic microcontroller, 2x ULN2004 Transistor arrays, DS1307 RTC & LM35 temp sensor.
Piece of paper over the leds to diffuse them as to bright for camera.
@Tuxdiver pretty good little chip, comunicate with I2C, has a battery backup input from a CR2032 cell so you can turn off and time is kept, the main reason i use it

Nice, compact setup! I have to take a look at the DS1307 for own projects...
