    A freeware Qt based project which targets a Calculator which has views of bin/dec/hex in the same window. I have missed this feature in legacy calculators and some of the colleagues asked about it too, hence the origin of the idea.

    DOFView

    DOFView

    Graphical Depth of Field Calculator

    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.

    Emulator of Wang 700

    The functional model of the old calculator series Wang 700 and 15VSM

    This project introduces a console application designed for functional emulation of the USA old calculator series Wang 700 and their USSR derivatives 15VSM (15ВСМ). The main goal of the project is emulation of those models made in Soviet Union: 15ВСМ-5, 15ВМ16/32/128 - which are also known as D3-28 (Д3-28). The choice of them is due to the extremely strong and authentic CPU command set developed by Soviet engineers as a superset around the original Wang 700's command set. While Wang 700 were just programmable calculators, Soviet machines were almost complete computers taking into account their advanced CPU command set, huge RAM volume, ability to work with wide set of peripheral devices including the video terminal 15IE (15ИЭ) and existence of BASIC and other programming languages written as loadable applications. Still I consider them as calculators also due to some aspects exclusively specific to calculators. The project is intended for research and education purposes.

    Evrika

    Evrika

    Science simulator and advanced calculator based on modules

    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.
