I 'd like to recommend a new free
online electronic circuit design tool.
There are several free EDA tools around and some excellent FOSS tools such as KiCad and gEDA but the reason I thought people might be interested in this one, EasyEDA, is because it has a few twists to it.
i) it's web based so, with nothing except a bit of javascript to install, it can be used by Linux, Mac and Windows users and if they have a big enough screen - Android and iOS users too;
ii) work can be shared and - with a bit of agreement on who saves what, when via a 3rd party instant messaging service - it supports collaboration;
iii) it has some pretty impressive import and export options such as importing Altium, Eagle and LTspice files and exporting spice netlists and svg, png and pdf files for documentation. It also uses open standard JSON format files internally so it's easy to do some quite whizzy things just using a text editor;
iv) all use of the tool is free even to the point where the user can download PCB Gerbers and send them off to any PCB supplier;
v) it also offers a low cost PCB service: PCBs can be ordered directly from within the tool (this seems to be the way the money is made to keep the whole thing afloat);
vi) it can even be used without registering with files being saved in an Anonymous mode that works a bit like pastebin where files can be retrieved and shared just by their urls.
It's easy to drive for there are lots of examples on the site and a useful tutorial.
