Circuit Wizard Downloads

From this page you can download a range of sample circuits as well as working versions of the circuits used throughout the series.

Important Note Regarding Circuit Wizard Sample Files:

The Circuit Wizard software is available in three different versions; Standard, Professional and Education. The availability of certain sample files, components and/or equipment will depend on the version of the software that you have purchased. The circuits provided below are compatible with the Education version. This is the version used by schools/college (our primary audience for the teach-in series). Readers with alternative versions of the software should follow the tutorials within the series to create their own files as is the intention of the series. Regrettably we are unable to provide our sample files in every possible format.
