This is a Raspberry Pi Clock using Adafruit 7 Segement clock display and an adafruit OLED screen to display additional information (Weather on mine). It also uses an adafruit level converter to safely run the LED display at 5V.
To make, solder the Adafruit parts, and wire up according to the wiring diagram.
Follow adafruit's detailed instructions for installing the displays.
I'll put the Python scripts on my blog at smunn.co.uk
