Most electronics design tools assume you already know how to read a schematic. They open to a blank canvas, hand you a symbol library, and […]

If you do any work with maps that goes beyond drawing pins on Google Maps, Quantum GIS is probably the application you end up using. […]

Traditional 3D modelling asks you to think about vertices, edges, faces, which is a strange way to design a face or a creature. Sculpting asks […]

Building an antenna and then measuring it is expensive in time and aluminium. Modelling it first costs an evening. 4nec2 puts a well-established calculation engine […]

The DWG file format is the lingua franca of technical drawing, the thing architects, engineers, and drafters trade back and forth all day. The problem […]

Atmel Studio will enable you to accomplish various tasks to convert your codes into a fully functional program. You can easily debug the AMR and […]

Circuit simulators divide into the ones with a node limit and the ones you pay for. LTspice belongs to neither, running circuits of any size […]

Autodesk 123D Design is a free 3D modeling application built around primitive shapes, simple sketching, and direct-modeling operations like extrude, push-pull, and combine. The tool […]

Estlcam turns drawings into CNC toolpaths with a directness that the big CAM suites abandoned years ago. Load a DXF or SVG, click the contours […]

Free42 puts an HP-42S on your desktop. Not a picture of one, a working one. The HP-42S was the scientific programmable calculator that engineers and […]

Take the guessing out of installing your new antenna with Satellite Antenna Alignment, which is a great app if you’ve just bought a new antenna […]

DWG TrueView is the official way to open DWG drawings without owning AutoCAD, and that word official carries the whole product. DWG files render here […]

FreeCAD builds 3D objects from dimensions you can change later. Draw a sketch, give its lines lengths and angles, pull it into a solid, then […]

TI Connect can be downloaded as a package bundle. This package bundle contains the explorer of a device, data editor, backup and storage tools, and […]

KNIME builds data analysis as a diagram. Each step, reading a file, joining two tables, filtering rows, training a model, drawing a chart, is a […]
