Need some PCB design software? Well you have a few options, free and not free. These are CadSoft Eagle and Novarm DipTrace or Altium respectively. The full Altium package costs around $15000. There is, obviously AutoCAD, but which hobbist has money for that? Although there is AutoCAD 360, which is free. However, which one is right for you?
The options available
Now CadSoft Eagle is great for hobbist projects, and there is also an OS X version, but for more serious projects, Altium is an industry standard. You can’t really compare the two, Altium beats Eagle hands down. They are not even in the same category. Altium is proper CAD software, actually an EDA (Electronic Design Assistant) whereas Eagle is a glorified pencil/eraser/paper replacement. Eagle is essentially hobby level stuff, and doesn’t look nearly as good on the resume.
For your home PCB needs, both will get the job done, but it is better to take the opportunity to learn a proper package like Altium that’s widely used in the industry.
However, if you just want to get a PCB etched at home, then DipTrace is good enough, and there is a version for OS X, as well as Windows and Linux.
