Marlin is a popular open source firmware for the RepRap family of 3D printers. It is straightforward, reliable, extensible and adaptable, which is why it is used by many respected commercial 3D printer vendors as well as hobbyists. It runs on inexpensive 8-bit Atmel AVR micro-controllers, with added support for 32-bit and ARM-based boards. Marlin builds can be small enough for use on a headless printer with only modest hardware, and features can be enabled as-needed.

...This project provides a very low-cost open-source "Hardware and Software" for a Cardiac Rhythmic Holter. The hardware has been made very simple and is based on an Arduino Nano micro-controller with boards for SD card mass-storage, instrumentation differential amplifier and RTC. It can help monitoring arrhythmia syndromes such as bradycardia, tachycardia, extra-systoles, pause or flutter. WARNING: In no case it can be use to replace a professional medical examination. Device MUST NOT BE CONNECTED to appliance powered by mains - risk of electrical shocks ************************************************************************************** see also: ECG Logger Viewer application : https://sourceforge.net/projects/ecg-logger-viewer/

If two or more people are responsible for something, either both do it, or none. Less often it only gets done once. This is an AVR ATTiny84 project that has features like putting the microcontroller to sleep to save battery. One button is to change from AM or PM, and the other is to turn on one of the LEDs representing the current choice for 5 seconds. The unit then goes to sleep, and the LEDs are off. It is powered by an 18650 and I put it all in a medicine bottle. A description of...

...We would also like to experiment with a "Delta" version which could use either bare RF or WiFi to exchange state data between machines. A "hive mind" if you like. For the new-generation version, we propose targeting two hardware platforms: 1. Arduino, since it's cheap and easy to use, while remaining close to the bare metal 2. A purpose-built AVR card, or easily ported to cards obtainable from sources such as futurlec.com, etc. RaspberryPi is also an option later

An Arduino pseudo OS with a focus on data acquisition and control.

A small program for an Arduino compatible micro controller that controls the flight of a model (water-) rocket. It does control the preparation of the recovery system, has automatic launch detection, an apogee detection system, parachute deployment, and safety timers. All this is managed with the most simple one button and one LED user interface.
