Life long experimenter - It can be done. M.C.S. home page - Мозилин фајерфокс (Mozilla Firefox) Turn your EAGLE schematic into a PCB. In a previous Instructable, I provided an intro to schematic entry using CadSoft's EAGLE editor. 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 is available from 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.
