View Full Version : CircuitLab - Schematic entry and simulation in your browser.

Here is one of the most amazing web apps I have ever seen.
Edit electronic circuits and simulate them in you browser. Share the results.


Must be useful around here when discussing circuit options.

I saw that site mentioned yesterday on Slashdot and was going to recommend it, too, until I tried it out. That so much can be accomplished in a browser is amazing, for sure. But until they support rubberbanding of connections, it's a very klutzy tool to try to use. The other thing that's irksome is that no dots are placed on 3- and 4-way junctions.

Yes I found a few minutes to play with CircuitLab at lunch time today the lack of rubber banding and dots immediately bugged me too.
Still, as I said might be good for those quick little circuits you'd like to explain in a forum post or such.

It's early days for all this "in browser", "web based", "cloud", "web 2", whatever you want to call it stuff. Just recently at work I reimplemented a little app in Java script using WebGl and Web Sockets. The previous incarnations of this were on C++ (Qt) and despite the fact it was available for Windows, Mac and Linux and was quite useful nobody would bother to install it and use it. As a web app it's a hit and, when they catch up, will be usable on pads and phones as well. Not only that the JavaScript version was a lot easier to create than the C++ version. After all these years I suddenly found I could stomach doing this, thing is with the new standards coming on line I can make something for the browser with almost zero HTML which always looked like a big mess to me.

Not being a user of simulators...what are the pro/cons of Spice versus CircuitLab?

02-29-2012, 06:12 PM
It looks as though it uses SPICE.

I wonder if it can export a netlist?

Pretty cool. This will be very handy for demos, or when you need to whip up something quick and don't necessarily have your laptop with Eagle or DipTrace or the like installed.
