Open Source Mac Calculators

The Revolution-FX project goal is to provide the best platform for developing applications for the CASIO fx-9860G graphing calculator. Revolution-FX components include addheader, code editor, a hardware library, and works with the GNU toolchain.

DOFView is a "Depth of Field" Calculator. It is a small application written in C++/Qt for Window and Linux to evaluate the effect of the focal, subject distance, and the f-Number change, on the depth of field. DOFView will report near and far distance limits, hyperfocal, total DoF etc., both in textual or graphical format. A simulation of what can be seen in the camera viewfinder is also shown in 3D. The application was inspired by my Nikon D5100, even if the user can set information and use this program selecting among hundreds of compact or DSLR camera models.

Evrika is a science simulator and advanced calculator, which is based on modules. Modules are libraries containing definitions of concepts that can be used in the simulation. By definitions we mean properties, actions, reactions, etc. Evrika is used for creating both simulations and modules, so you can build your own module of elements, then use them to create virtual experiments and simulations. Also, you can make advanced calculations. Evrika is basically an executable that reads and interprets code, outputing result. Each new version will offer new possibilities to define your elements and use them, so it is important to always have the last release. Of course, Evrika is backward-compatible, cross platform and free to use. In the near future an advanced editor and viewer will be created, so you can better manage your code and view the results.

OpenRPN is an initiative to design and produce ultra high-quality calculator hardware and software for advanced students and professional users.
