Ace is a micro kernel for developers and researchers. The main goal is to create a very light and compact kernel from scratch with modern OS research concepts.
An operating system kernel designed with simplicity, readability, and elegance in mind. No longer written from scratch, but built on "the shoulder of giants." Specifics are given in the CREDITS file starting from v0.04
Longene ( Linux Unified Kernel ) is an open source project sponsored by Insigma Co., Ltd. It aims to implement a kernel module in Linux that provides a system-call and driver layer to allow the Windows applications to run on the Linux OS.

Embeddable JVM is a JVM for embedded systems with no OS. Class files can be executed directly from SD card. Small memory consumption (512k is enough). Only FAT16 filesystem is supported for now. Tested on LPC2478 and LPC2939 boards.
Embeddedable Forth compiler is a Forth system for 32 bit devices with no OS. I am currently using it with ADUC7026 board. Also tested on STM32. Win32 version is is used for testing.
BNL OS is a free, modern operating system based on the design of Windows XP/2003.This is not a Linux based system, and shares none of the unix architecture. Please remember, this is in the development stage, and is not reccommended for everyday use.
OpenCom is an open-source component programming model designed by the School of Computing and Communications at Lancaster University, UK. This project maintains the official C language version of OpenCom.
Project-Sparroh is a hobby operating system project. Goal is to write an OS from scratch for the purposes of learning how they work and for fun. An assembler and high level language cross-compiler will also be written first and used to build the OS.
CapROS is an experimental capability-based operating system, based on EROS, KeyKOS, and Gnosis. Ports exist for the Intel IA-32 and ARM9 architectures.
a kernel for many architectures. the kernel is a micro-kernel which can be used as an hybrid- or monolithic-kernel. the kernel is written in assembler and C.
One day there will be a Windows 9, coming after Windows 8 and current Windows 7. Why not starting working now on a Windows 9 similar open source OS ten years before it appears instead of still working on it 10 years after it will become obsolete?
yaMOS stands for: yet another "My Operating System". This is a hobby Operating System, let's see to what it develops... At the moment it's only a kernel written in C++ and Assemly.
Free and simply RTOS for AVR at assembler. So far, the AVR Studio is used as a development environment. The system supports the preemptive and cooperative multitasking modes, semaphores. Use a small amount of memory for tasks.
