I'll throw my hat into the ring as well. I have also recently been building a small signal AC analysis circuit simulator [1]. The main idea behind it is to convert a closed source tool that has been around for years within the LIGO scientific collaboration to one that is open source and implemented in Python. It's almost functionally complete, can simulate transfer functions and (accurate) noise from op-amps, resisto…

Looks pretty cool but the input is pretty esoteric to a newbie like me: https://git.ligo.org/sean-leavey/circuit/blob/master/example...

Same thing about the output format: https://git.ligo.org/sean-leavey/circuit/blob/master/example...

Is this a custom file format or a well known one?

Also, the references to LISO are all behind a user/password wall, which makes it hard to learn: https://wiki.projekt.uni-hannover.de/aei-geo-q/start/softwar...

I used and enjoyed circuitlab.io until it went for-pay only. Nice to have an easy to use free alternative for very casual hobbyists like me.

That would be https://www.circuitlab.com/ -- I built it :) Edit: if anyone wants, reply with your CircuitLab username and I'll give you a free membership upgrade when I get home this evening.

Very generous of you. I've loved using it to answer stackexchange answers but don't have enough use myself to justify the membership.

Thanks so much for the upgrade!

Paul Falstad did (and does) all the heavy lifting for this project, but the co-host of the JS version at lushprojects.com is my site and I did the original port from a Java applet to a GWT application that complies to JS. Glad to know so many people find it useful. I always thought it was a great visualisation tool which I why I wanted to put the effort in to do the port. Off to bed now, but if people have questions…

Where do I learn to write simulations like this? I'm doing numerical models this summer, and it feels like a lot of the notation is inconsistent, unlike programming.
