=== Radio Stack ===
I started building a radio stack from spare parts. An old 19" token-ring hub was emptied from all content and now gives a nice chassis for the radios. All elements communicate via the I2C TWI interface of the used AVR microcontroller and are bridged with an [http://www.harbaum.org/till/i2c_tiny_usb/ i2c_tiny_usb] I2C/USB interface to the FlightGear computer.
