SOSSE (Simple Operating System for Smartcard Education) is a free smart card operating system. It is implemented in C and assembler for the Atmel AVR smart cards (Funcard, PinkCard, Jupiter). The aim of this project is to provide something like Linux for smart cards, which is a market full of NDAs. SOSSE should make it possible to learn about smart cards, and to implement and test your own ideas.
WISP-Dist is a modular embedded Linux distribution for wireless routers, but can be used for other purposes as well. The entire system fits in 8 MB flash/16 MB RAM. Highlights include an easy-to-use menu interface, commandline access, an Access Point mode (on selected cards), OSPF/RIPv2, bandwidth shaping, NAT, Layer 3 (proxy arp) bridging, and other goodies. The goal is to create an open, customizable, and easy-to-use solution for wireless routers.
execline is a very light, non-interactive scripting language, which is similar to a shell. Simple shell scripts can be easily rewritten in the execline language, improving performance and memory usage. execline was designed for use in embedded systems, but works on most Unix flavors.
Player provides a language-independent networked interface to robots and their sensors. Supported devices include Pioneer 2DX robots with sonar, odometry & compass, SICK laser rangefinder, ACTS color vision system, GPS, gripper and wireless communications. Stage provides a population of simulated Player devices. Controllers designed using Stage have been shown to work unchanged on real robots and vice versa. Stage aims for low-fidelity simulation of many devices, rather than perfect models.
