circuitjs1

I remember the guy behind VoltSim posting his project on reddit some months ago, claiming he wrote the circuit simulation under the hood from scratch by himself. When he was called out that all his components used the same values and variable names as falstad [1], implying he just ported falstad's circuit sim to android, he deleted his post. Looks like he still has his app on the app store and is still not honoring the open source license and not giving proper credit to falstad's circuit simulation. And now he even put many components behind paid "extension packs" and wants to make money from falstad's work. [1] https://github.com/sharpie7/circuitjs1

If you like everycircuit you should also try this circuit sim in the browser. It is really cool - especially for learning/teaching: http://lushprojects.com/circuitjs/ It was originally developed as a Java applet by Paul Falstad. As Java in the browser got more and more troublesome I modified it to work with HTML 5 for a plug-in free experience. We agreed to release the new version as GPL: https://github.com/sharpie7/circuitjs1/network

Check. Denigrating the hard work of others is not cool, especially when they make it freely available to others.
