Many electronics hackers have habit of using Eagle to design their PCBs. You’ll find plenty of support for this software as well as a lot of parts libraries, the free version of Eagle software comes with limitations (board area is limited to 4×3.2 inches, only two signal layers and the schematics editor can only create one sheet). You might want to check out if there are any good open source alternatives without restrictions?
KiCad is an intereresting open source EDA software for Windows, OSX and Linux. Create PCB circuits for free with the most advanced features. With the schematic editor you can create your design without limit; there are no paywalls to unlock features. An official library for schematic symbols and a built-in schematic symbol editor help you get started quickly with your designs. It can make professional PCB layouts with up to 32 copper layers. KiCad also includes a 3D viewer which you can use to inspect your design in an interactive canvas. You can rotate and pan around to inspect details that are difficult to inspect on a 2D view.
EEVblog #253 – KiCAD Install & Schematic – First Impressions video is a continuous 45min screen cast of Dave installing and running KiCAD for the first time, along with his first impressions and rants about things he finds along the way, mainly with the schematic editor portion of the program. How easy and intuitive is it to use the schematic editor for the first time?
For more advanced introduction check out KiCad video series: from concept to manufacture. It shows people how to design and build their very first PCB using this software

CERN Shows Off New KiCad Module Editor CERN, the people that run a rather large particle collider, have just announced their most recent contributions to the KiCad project. This work focused on adding new features to the module editor, which is used to create footprints for parts. The update includes support for DXF files, which will make it easy to import part drawings, or use external tools for more complex designs. CERN has already implemented a new graphics engine for KiCad, and demonstrated a new push and shove routing tool. Check out the CERN KiCad Developers Team on Launchpad.
