The web pages you are watching are served by a web server running under the Contiki operating system on a small sensor board developed by the CST group at FU Berlin. The sensor board is equipped with a TI MSP430 micrcontroller with 2048 bytes of RAM and 60 kilobytes of flash ROM, as well as a number of sensors. The sensors can measure vibration, temperature, IR-light, sound, tilt and motion.
The sensor board is directly connected to the Internet through the RS232 interface on the board, and is running the uIP TCP/IP stack on which Contiki is based.
The entire Contiki MSP430 system uses only about 1800 bytes RAM, of which 280 bytes is used for the virtual screen and 300 bytes for network buffers. All code and web pages are stored in the microcontroller's on-chip flash ROM.
