Qucs is a GPL circuit simulator. And if you want the GUI option, you might want to try out QucsStudio, which uses Qucs under the hood, and is free to use, but binary-only.

The Solution Simulator enables web-based electrically and thermally coupled analysis of semiconductor chip (junction) temperature during operation, as well as pin temperatures. It also measures the ...

The new Circuit Board skins are printed using Dbrand’s new “three-dimensional UV printer” that can print two-dimensional imagery but with certain elements having a slightly raised texture.

The skin, which is textured, matches the design of a real-life circuit board. In regular lighting, it has a black and off-white look, while changing to a glow-in-the-dark green when the lights go out.

Stanford scientists have developed a new circuit board modeled on the human brain, possibly opening up new frontiers in robotics and computing. For all their sophistication, computers pale in ...
