FreeMat – Engineering Technical Computing

FreeMat is a free environment for rapid engineering and scientific prototyping and data processing. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source. FreeMat is available under the GPL license.

FreeMat – Engineering Technical Computing

FreeMat - Engineering Technical Computing

FreeMat is chartered to go beyond MATLAB to include features such as a codeless interface to external C/C++/FORTRAN code, parallel/distributed algorithm development (via MPI), and advanced volume and 3D visualization capabilities.

Features Include

  • N-dimensional array manipulation (by default, N is limited to 6)
  • Built in arithmetic for manipulation of all supported data types.
  • Support for solving linear systems of equations via the divide operators.
  • 2D plotting and image display
  • Arbitrary-size FFT support
  • Pass-by-reference support (an IDL feature)
  • 3D Plotting and visualization via OpenGL

Minnitron Ltd - Printed Circuit Manufacture

“From literally the “Garden shed” in 1962 the founder George Goodfellow was the catalyst for a long future in the manufacture of Printed Circuit Boards. Board types manufactured today include single, double and Plated Through hole, plus multilayer boards up to 10 layers.”

Current Carrying Capacity Calculator

“All conductors which carry current will be at a temperature higher than air temperature by a temperature rise (above air temperature) T which depends upon current carried (I) Amperes , conductor width (W) and copper thickness.”

Kicad Open Source EDA

Kicad is an open source (GPL) software for the creation of electronic schematic diagrams and printed circuit board artwork.

KiCad EDA Software Suite

Designed and written by Jean-Pierre Charras, a researcher at LIS (Laboratoire des Images et des Signaux) and a teacher in IUT de Saint Martin d’Hères.(France), in the field of electrical engineering and image processing.

KiCad Schematic

The electrical rules check (ERC) automatically verifies your schematic connections. It checks for output pin conflicts, missing drivers and unconnected pins.

KiCad comes bundled with a vast library of symbols, footprints, and matching 3D models. They are community maintained so they never stop improving.

Make professional PCB layouts with up to 32 copper layers. This modern tool will help you lay out your board faster. As you draw your track, it pushes forward traces that are in the way. If that is not possible, your track will be rerouted around obstacles.

KiCad PCB

KiCad consists of ..

  • kicad – the project manager
  • eeschema – the schematic editor.
  • cvpcb – the footprint selector for components used in the circuit design.
  • pcbnew – the PCB layout program.
  • gerbview – the Gerber (photoplotter documents) viewer.
