LifeClock is a self-contained project kit that marries an ATmega328P to 110 LEDs to play Conway's Game of Life and tell the time. It also displays the temperature and humidity between every new game. Although the microcontroller is preprogrammed in the kit, the TX and RX lines are brought out as a standard FTDI header to allow for software updates or your own imagination. Programming is simple through the Arduino environment and an FTDI cable. The necessary libraries are provided and the source is available for your own modifications.
All components are through hole and simple soldering gear is required. You will need a soldering iron, solder and diagonal cutters. Power is supplied through a standard USB A to B cable (not included) or the FTDI header.
ATmega328P as the main microcontroller - compatible with the Arduino environment, although the sketch as provided requires some tweaks to the distribution to allow it to compile in the available memory.
DS1307 as the realtime clock, backed up by a CR2032 to keep the clock running when the system is disconnected from normal power.
DHT11 provides a general sense of humidity. The accuracy isn't anything to perform experiments against, but it's useful as a general sense of humidity.
DS18B20 providing a more accurate temperature reading than the DHT11 can offer. The temperature is displayed in Fahrenheit.
This video demonstrates the normal running appearance of the LifeClock.
I'm willing to ship internationally, however the code currently only displays Fahrenheit temperatures. Changing it to Celsius just involves a quick change to the code and re-flashing the chip, but it will take a day or so to personalize the chip.
