Best Schematic diagram drawing software

When I think about schematic, Circuit LAB is the website coming at first.

Circuit LAB Website: Circuitlab.com
This website is very intuitive simple and efficient supports schematic sketching, simulation and even sharing with your friends!

The most beautiful thing, we can build and test everything in a browser!
Circuit Lab features:

• Design with our easy-to-use schematic editor.
• Accurate analysis (DC, AC & more) in seconds.
• Beautiful printouts, images, and live links to share
• No installation required -- try it instantly in a browser.
• Over to you Collegelib Electronics engineers! Experience it, It is free and you will love it(like me).
  

Here is an LC circuit I just drawn for Collegelib



Paper and pencil for Schematic
If you do not have internet connection or a laptop with you, definitely the the efficient way is to use a pencil and gridded engineering paper. You may copy this to your mobile camera and copy to your computer for sharing with your batch mates then :)

Did you find Circuitlab helpful? Tell us your opinions...

Wow Circuit Lab looks awesome. I do prefer working on local files instead of ones that are on "the cloud". I use Eagle PCB design software to create all my circuit schematics. The cool thing about Eagle is that I can also create the PCB layout with it.

Hi protoboard, thanks for coming up and Welcome to Collegelib.
Eagle is an excellent software, I too use it some time. As I said, preferring Circuit Lab because it is easy to use within a browser, Linux/Windows or even from your mobile browser!
