Ever wanted to quickly calculate the value of your resistors? Well now you can with Ohm´s Calculator. With this program you can calculate resistors values if you have the colors. But what if you are trying to calculate SMD resistors. Don´t worry this program do it for you.

You can even calculate voltage, amperage, resistance and power if you know two of those values. And if you are not confortable with the results you can always verify it with the Power and Ohm´s Laws formulas provided with the program.

With this tiny tool, electronic or electrical guys no longer need to remember the color bands anymore.

Requires: Microsoft .NET Framework 3.5.

PocketCAS is a free interface to the open-source Computer Algebra System giac/xcas.
xcas enables you to quickly solve complex algebraic problems, e.g. symbolic and numeric integration and derivation of non-trivial functions, solving differential equations etc. It has also a huge support for problems of linear algebra, like solving linear equation systems, multiplying and inverting matrices, finding eigenvalues (and eigenvectors, of course) and much more.
