Schematics and Circuit Simulation In the Browser
compumike writes "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."
I think it is important to mention Paul Falstad's Java circuit simulator that has been around for years and has probably influenced this project. http://www.falstad.com/circuit/
http://www.falstad.com/circuit/ is nicer; it simulates in real time and isn't as clunky because it runs as an applet instead of javascript hackery.
