Open source hardware refers to computer and electronic hardware that is designed in the same fashion as free and open source software (FOSS). Open source hardware is part of the open source culture that takes the open source ideas to fields other than software.
A web page on how to make a simple ECG (electrocardiograph - also known as an EKG). On it you will find information how how to build one with less than $10 in parts.
A repository of information about one persons attempts to build ECG machines (also known as EKG machines) from spare parts and retired medical equipment. Includes FreeECG - the free ECG & EKG software.
An online community conceived around a simple, but challenging and worthy goal - to develop an open source hardware and software solution for electrocardiography. This is essentially a playground designed for people of different backgrounds to put their minds together and create something that could make a difference in this world.
Open Circuits is a wiki for sharing open source electronics knowledge, schematics, board layouts, ports and parts libraries. This include open hardware Music Players, atomic microscopes, PC, PDA and mobile phones, and batteries. Please help us to build this resource by submitting your component descriptions, projects, techniques, and PCB footprints.
The OpenEEG project is about making plans and software for do-it-yourself EEG devices available for free (as in GPL). It is aimed toward amateurs who would like to experiment with EEG. However, if you are a pro in any of the fields of electronics, neurofeedback, software development etc., you are of course welcome to join the mailing-list and share your wisdom.
Right now, this site is mostly about the hardware; schematics, part lists, building instructions etc. However, a few members have developed some useful software which is hosted on their own websites. You can find these through the software pages.
We distribute the open-source physical computing platform called Arduino. Arduino is based on a simple i/o board, and a development environment for writing Arduino software. The Arduino programming language is an implementation of Wiring, itself built on Processing. Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other outputs. Arduino projects can be stand-alone, or they can be communicate with software running on your computer (e.g. Flash, Processing, MaxMSP.) The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free.
PCB is an interactive printed circuit board editor for the X11 window system. PCB includes a rats nest feature, design rule checking, and can provide industry standard RS-274-X (Gerber), NC drill, and centroid data (X-Y data) output for use in the board fabrication and assembly process. PCB offers high end features such as an autorouter and trace optimizer which can tremendously reduce layout time.
a repository for symbols, footprints and documentation that are useful to anyone using the GPL schematic creation program gschem or the GPL pcb layout program PCB. The misson of gedasymbols.org is to increase the usage of the gEDA suite of tools by distributing symbols and footprints for these programs, as well as other third-party add-ons and tools.
