Components

Lists of components, where to purchase them, how to use them. For many components there are links to projects using that particular component, this is especially true for microcontrollers, for example follow the links down to PIC microcontrollers and you will find many project links as well as tutorials.

Test Equipment and Other Equipment

See what is going on in your circuits, charge your batteries, etc.

Basic Circuits and Circuit Building Blocks

Circuits you will use over and over.

Techniques

How to do things.

Tutorials

How to understand and plan what you are doing. These are for general theory, more specific information is linked to its topic.

PCB Footprints

Don't reinvent the wheel. Known working open PCB footprints for various components.

HackerSpaces

And hacker orgnizations. These are the white hat guys hacking electronics to make things. Includes DIY types, the people who read Make Magazine.

Got A Blog, Wiki or Website?

Link to it on the Got A Blog, Wiki or Website? or WikiNode page.

Got a Technical Question?

Perhaps it will be answered, perhaps not. Google for it first in the spirit of RTFM. Please do not ask us to do a school project for you.

Meta Open Source

Not projects or information on projects, but stuff about the open source movement ( mostly hardware ) itself.

Open Hardware Initiatives

The Open Source Movement, typically covers Open Hardware, Open Firmware, and Open Software.

Open Hardware is similar to Free and Open Source Software.

The Open Firmware movement provides firmware (i.e.: micro-code specifically related to the subcoding of hardware devices) which you may also know as soft-IP or FPGA coding see Open Cores for more details.

Excellent examples of Open Hardware projects range from projects at OpenCircuits to Tiny Embedded Ethernet Devices and Advanced & Intelligent Camera Designs which provide solid-state camera and FPGA assisted hardware designs. A solid overview of projects can also be found at Open Innovation Projects.

Licenses

The most common "open hardware" licenses are the Creative Commons Licenses and the GNU General Public License. The GNU people wrote the the GPL FAQ to deal with common questions and misunderstandings of the GPL. The GNU people go on to say

"We encourage people who redistribute free software to charge as much as they wish or can. If this seems surprising to you, please read on." -- GNU: "Selling Free Software"

For example, Linksys makes money selling (among other things) their Linksys WRT54G series routers, which use Linux under the GPL license.

To understand what your entitlements and responsibilities are under the applicable license(s); each hardware, firmware and/or software piece you have either copied, modified, developed using tools provided or if you intend distributing your development, you MUST read each and every license, and be specifically aware that you may not mix such license(s) together unless they can co-exist under one umbrella license. For example you may modify, copy, enhance and distribute parts your project which are all under the same license e.g.: GNU General Public or Open Circuits:Copyrights.
