The weather display is basically four Adafruit 8x8 LEDs matrices using I2C connected to a Raspberry Pi Model A with a USB wifi dongle all housed in a nice wooden case with a glass front. A python program (weatherx.py) pulls a forecast from NOAA and updates the LEDs to indicate the weather for the next four days via cute icons. The python script is launched daily (early AM) via cron.
