A really impressive FOSS CAD app. Cross platform, works in Windows, Linux and MAC. Scriptable using Python
Here is a video of my Antenna Tracker being designed with FreeCAD
A comprehensive FOSS Electronic CAD package for designing PCB's. Does nice schematics too.
Also works well to get PCB's made e.g at OSH park
CAD app which uses a C like scripting language. This is great for making objects, which use some sort of repeating pattern or algorithm, where a traditional CAD app, can be time consuming. Great things is the scripts are also embeddable in FreeCAD.. Brilliant!
A great way to get PCB's made at a reasonable price. Saves all the hassle of trying to make them yourself. You just upload the files, then they are checked and (if they are ok), they give you a price. Pay online ( e.g using paypal) and your boards are immediately on the way to the pcb fab in the next available batch. Really professional boards too.
