Now we’re talking, Windell @ Evil Mad Scientist Laboratories has a great write up of laying out printed circuit boards with open-source tools, he writes –
There has historically been, and still is, a lack of good, free MacOS native EDA (electronic design automation) software. The situation has somewhat improved in the past few years because the X11 layer in Mac OS X allows graphical unix applications to run natively on the Mac, concurrently with other programs. I recently learned to use some of these tools in the gEDA suite to lay out printed circuit boards. These (loosely, if at all, organized) notes should be helpful to anyone that wants to get started making PCBs using a mac, linux, or other unix-like system.
