Not being content with a simple foosball table, the team at Sinnerschrader in Germany have literally dragged the game into the 21st century. Using Arduino hardware and some photosensors to detect when a goal has been succesful, the game statistics are then sent real-time to an Internet service to collate the data and also display it using mobile apps. Watch the following video for a brief introduction:
This project has to be one of the most amazing examples of updating a game to the 21st century. Furthermore, Sinnerschrader have made the software and designs open-source so you can recreate or modify the project with your own foosball table.
To get your own foosball table or other project connected to the Internet, consider the Freetronics EtherTen - the Arduino Uno-compatible board with onboard Ethernet, microSD card and optional PoE support:
