Still curious about FidoCadJ? Give it a try!

FidoCadJ is a very simple vector drawing program. A lot of symbols for electronic circuits are included, but you can draw more or less anything. You can build your symbols and reuse as much as you want. FidoCadJ is routinely used in forums and in blog posts, as the file format is perfect for sharing drawings. FidoCadJ is complementary with the big EDA electronic tools. Ever tried to include your schematics in a document or in a presentation? Were you happy of the result? FidoCadJ can export drawings in several graphical formats (PDF, EPS, SVG, PNG, JPG). LaTeX users will be happy about the possibility of including drawings in documents via the PGF/TikZ export.

FidoCadJ is the official drawing tool of ElectroYou, the italian social network for electronics.
