circuit simulators

I was searching for some free circuit simulators. Below are some cool web versions of circuit simulators.

Looking for these features can be brought into a Electronics course making tool.

Easy jump to OS building ..

I know the basic components of an Operating system . The basic theories around OS like application layer, kernel, system calls, boot loader,BIOS etc.  But I am scared to write one OS.. But below blog is motivating me to make an attempt to write an Operating system of My own.

why to build a Circuitacademy ?

I would like to build a circuit academy - online electronics courses study and practice website. But not sure where to start with :-)

Below link has the more details.

circuitacademy

Most of the btech students loose their electronics interest after btech because there is no opportunity or good practical simulation examples of  circuits. They will be studying lot of theories and basic circuits. But real world circuits are complex, but it's difficult to practice or build these basic circuits. Online electronics courses are very less and there is very less opportunity for a electronics student to practice and master these basic and complex circuits . If you see www.codeacademy.com, there will be lot of courses in computer programming related subjects and we can practice programming languages. So the aim of this web application to help electronics enthusiasts to build and practice electronics courses and share it online. The challenges/difficulty in building electronics courses will be -

There should be EDA tools(given in next slides) available in the course tools bar for teachers to build circuit and play and show during the courses.

 


Please let me know if you are not able to open the link. help me on how to start with this project.
