Interesting /. find: CircuitLab - "Build and test circuits right in your browser"

"CircuitLab today released a browser-based schematic editor and
circuit simulator for the online electronics community. SPICE-like
device models and mixed-mode simulation support allows engineers and
hobbyists to tackle a wide range of board-level design problems. While
most EDA software is Windows-only, CircuitLab is 100% web-based,
Windows/Mac/Linux cross-platform, and requires no installation or
plug-ins. Instead of today's typical forum posts with static
screenshots from different desktop tools, the online electronics
community can now use CircuitLab to share useful URLs (as well as PNGs
and PDFs) which link directly to interactive, editable, runnable
schematics. In just a few clicks, another designer can open that
circuit, make a change, simulate it, and post the new version back to
the community."

While not strictly *free software* like the FSG would promote, it's
still free as in beer.

I see this being very useful for students taking EE/CPE as it may
remove one more reason for students to have to be in the ESB to get
homework done. Can anybody play with it a bit and see if it's
something worth promoting around the department?

I looked this over very briefly. At first glance, it appears to be a decent piece of software, especially for circuits 1 and 2 courses. The app can solve DC circuits, which is most of what circuits 1 covers. It can definitely be a good solution checker for homework and projects. I didn't spend a lot of time learning the interface but managed to get the hang of it relatively quickly.

Considering setting up PSPICE can be an annoying process, and the fact that you can save your files online, I would recommend this as an alternative or supplement.
