1 × DS3231 High Precision Clock Module These are just a couple of bucks, perhaps even under $2 on ebay. I think i got mine from banggood, like this one: http://www.banggood.com/DS3231-AT24C32-IIC-High-Precision-Real-Time-Clock-Module-For-Arduino-p-81066.html
1 × JY-LM1640 16 digit 7 segment display I got these from dealextreme a while ago, but a recent scan of various websites have failed to turn up a new source for them. Sad Panda: they are kind of cool, and some of the code here is pretty specific.
