Forget Eagle, forget gschem, use KiCad
install with ppa, not with the software manager! I'm a professional electronics developer. All my work is done with KiCad. In the last 2 years it has improved dramatically. The contributions from the CERN developers are great! The hierarchical schematics are great and the export to the industry standard format (GERBER) works perfectly. Keep up the development of this great suite!
You should use the PPA at the moment to get the latest version!
Almost as good as commercial software!
A great and efficient EDA software
Es gibt bessere Programme auch Kostenlos für Privat
A great and full-featured project. However, it is harder to use than DipTrace. It should force yourself to study it.
A great place to start learning EDA software. Open source, so no restrictions like Eagle. Best for simpler designs using through hole or single sided boards. 3D preview and hundreds of footprints and models in the community. Less flexible than gEDA, but easier to learn.
