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 reimplements from scratch the RPL language made popular by HP programmable calculators, in portable C/C++. The main goal is to release a complete computing environment for various targets. There's currently 4 active targets: the HP 50g, HP39gs and HP40gs calculators and a PC simulator (see the downloads section!). Other ports are planned for the future.

...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/

Used in physics, made to make calculating long variance and standard deviation equations simpler.
