Tux Droid by Kysoh
Tux Droid is a Linux wireless Tux mascot (210mm x 180mm x 140mm - with lowered wings) with a programmable interface, allowing it to announce events by its gestures and by ALSA driven sound. The events are detected by specific gadgets, which are handled by the Tux Gadget Manager. The Tux Droid supports Linux kernel 2.4 or later and needs an 800 MHz CPU and 128 MB RAM. It communicates by infrared to the USB port (1.1 or 2.0) and for media detection it needs an internet connection. The mascot is driven by Atmel AVR RISC microcontrollers. The new version supports also Windows-based PCs. The Tux Droid can be used with Windows XP and Windows Vista (both at 32 Bit).
