In this instructable, we'll make a printed circuit board from that schematic
I guess I should say that we'll make a PCB DESIGN; making the physical board is a different task, and there are a lot of tutorials on the net (and even some instructables) on making the board after you have the design.
Cadsoft EAGLE generic information:
Cadsoft EAGLE is available from http://www.cadsoftusa.com/
Cadsoft is a German company that is a veritable mecca of software distribution enlightenment. In addition to the reasonably-priced professional PCB design packages ($1200), they have freeware, lite, non-profit, and other intermediate licenses. Their software runs under windows, linux, and MacOSX. It's slightly quirky, with a steep (but not too high) learning curve on the front end, but from most reports it is not any more so than other professional CAD packages. They have online support forums that are active from both the company and other users, the package is under current development and gets better with each release. A number of PCB fabricators will accept their CAD files directly. It's good stuff.
Use it. Propagate it. Buy it when you "go pro."
