The WOLKs are stable and development kernels, containing many useful patches from
many projects. Goal: Stability, Scalability, Performance and most important: Security.
Nucleus is an Operating system Kernel that is totally different from Linux and Windows. It is easy to understand and implement. It will have native support, small architecture and full VGA support (no text mode).
Maiden-core is a Linux kernel robotics API module, extensible in Erc. The Maiden Project also documents and develops the Maiden architecture for mobile robots, a set of (optional) designs and standards for robots using the Maiden-core API.
AVOS is an advanced Real-Time 32-bit operating system that will work in any 80386 & above architecture pc's. AVOS employs a message passing scheme. The project has two main parts - The booting phase and kernel development. It is written in C and 8086 ASM.
Project to create a new microkernel for AdaOS. Intended to be especially suited to Ada programming language, but will have pragmatic design which is actually language neutral. Will be practical, general-purpose, and secure, but otherwise minimal.
XMK is a preemptive multitasking kernel for microcontrollers. Its goal is to provide a RTOS small enough (RAM+ROM) to run on 8bit microcontrollers. XMK provides additional/optional features when scaling up to 16bit and 32bit platforms.
Nemesis is a tiny real time operating system kernel based on x86 PCs.
Its main purpose is to serve as a simple but realistic example of an real time OS kernel running on real hardware..the purpose of this is that it can be embedded in small devices lik
Eclipse OS is a C++ kernel that I am starting as a summer project. Right now it is fully bootable and can accept input from the keyboard. It can also do simple tasks like detect how much RAM a computer has, or tell time. I am hoping to port C++ compiler.
