LabMonkey is a collection of designs for embedded devices which can be networked together to provide a range of automation, data logging and signal processing functions. A key design objective is to use as little dedicated hardware as possible for communication between nodes in the network, and to be able to adapt the network topology in real-time so as to minimize the occurrence of collisions between packets. To achieve this, a protocol has been designed specifically for the task, and implemented in assembler for AVR microcontrollers. ...

Spaceman Spiff's Chording Keyboard Experiment (or SpiffChorder for short) is an experimental platform for creating a USB chording keyboard. A chording keyboard or Chorded keyboard is an input device where characters can be typed by pressing multiple keys at the same time. A popular design is the 7-key chorder, where one key is used for each of the index finger, middle finger, ring finger and pinky, and 3 keys for the thumb. This can be used with either the left or right hand (or a chorder can be used for each hand, effectively doubling the typing speed). SpiffChorder hardware is based on Atmel AVR ATmega168, using Objective Development's V-USB (a software-only implementation of a low-speed USB device).

A system that allows people to open doors by using a Bluetooth enabled phone or other device.

FunkOS is an RTOS for 8-32 bit MCUs including AVR, MSP430, and Cortex M3. Both C and C++ kernels avaiable. Key features include preemption, periodic events, device drivers, and mutex/semaphores. Includes a variety of graphics and filesystem middleware. Please also check out FunkOS's big brother, Mark3OS. Mark3OS is slightly larger, but is more scalable, much more feature-rich, and supports a wider variety of devices.

This project designs the oswrap including task scheduler, timer, semaphore, mailbox, wait, memory key components. Support Linux and windows platform and distributed system.
