Main Page

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.

Projects and Ideas

Descriptions, instructions, board layouts, and other documentation for electronics

• projects and
• ideas.

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.....

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.

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 spirt 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 the hardware equivalent of the Open Source Software movement originally developed by GNU/Linux and the Free Software Foundation.

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.

Licences

You need to be aware that certain licencing may curtail you from commericalizing or using your development in the market. The GNU General Public License is one such licence, others are [Open_Circuits:Copyrights Attribution-ShareAlike], Creative Commons Licenses but be aware that there are many more.

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

Help Us Make Open Circuits Better

What are we:

Looks like we are defining this by way of who contributes and what. I ( russ_hensel ) am a new member so may or may not have it right. This is what I think:

• An introduction to Electronic theory, suitable for the hobbyist.

• Guide to locating and using components and tools.

• Details on how to build various projects.

• Building some sense of community among builders.

There are two means of carrying this out:

• Write material for the site or

• Link to material you may have written or have located on the web. There is so much stuff on the web that lets not write it here unless it is at least somewhat unique.

What do you think, discuss it here if very general, else on the discussion page ( link at top of page ).
