Slick and easy to use interface
From 2 comments
It looks nice and easy to use but I can't seem to get something as basic as a two-NOR flip-flop to work: https://i.imgur.com/V6yXpMl.png The gates themselves in isolation work…
userbinator on HNThis is really slick! Very nice job. I realize that this is primarily a tool for teachers but I would love to see more public tutorials and examples. I realize there are many…

userbinator on HNI believe that's quite the unfair comparison. Even if the components model aren't very sophisticated, everycircuit can do full analog simulations. If you use chrome, you can run…

Does not work well on mobile Safari
From 1 comment
Completely borked on mobile (Safari); views are squished with main circuit view being impossible to make out details.

Support for real LED rendering and custom backgrounds or text
From 1 comment
Couple suggestions, that would make it fun for youtube videos: 1. Let the user change the background, and add letters/text. 2. Ability to add sound effects 3. Rube golberg style…

Questions
How does the simulator handle cyclic circuits and timing
From 2 comments
Please look at the examples to see what the simulator engine is capable off. As for designing the simulator engine to solve these kind of cyclic circuits, and advice on how to do…
satu0king on HNAs for designing the simulator engine to solve these kind of cyclic circuits, and advice on how to do it? The general idea is to iterate while changes are still propagating…

How the simulation compares to real electricity
From 2 comments
I love tinkering with circuit simulators - this one seems really cool too, great work! Just wondering, from a programmer perspective: how do you simulate electricity? If you…
mrspeaker on HNThis one doesn't "simulate electricity" per se; it's a digital simulator, which means it evaluates the output of each node based on its inputs, and propagates the changes as…

Another good one is http://www.falstad.com/circuit. I remember using this quite a bit to double check homework.

Multisim and SPICE tools
From 2 comments
When I was at NI I helped build https://www.multisim.com which is powered by a full SPICE simulator.
etimberg on HNDepends on the quality of your SPICE models. (https://en.wikipedia.org/wiki/SPICE) When you model by hand you typically use ideal models. SPICE models can be vastly more complex.…
