If you like everycircuit you should also try this circuit sim in the browser. It is really cool - especially for learning&#x2F;teaching: <a href="http:&#x2F;&#x2F;lushprojects.com&#x2F;circuitjs&#x2F;" rel="nofollow">http:&#x2F;&#x2F;lushprojects.com&#x2F;circuitjs&#x2F;</a><p>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: <a href="https:&#x2F;&#x2F;github.com&#x2F;sharpie7&#x2F;circuitjs1&#x2F;network" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;sharpie7&#x2F;circuitjs1&#x2F;network</a>

I really like proteus from labcenter electronics. It isn&#x27;t as pretty as this tool (by a million miles), but it can actually simulate microcontrollers and even full-fledged ARM processors.<p>You can construct an arduino, as in drag it together in an editor similar to this one, run the USB port emulator on your local machine and run the arduino IDE against your simulated circuit, and program stuff to control servos or relays.<p>They&#x27;ve got such drivers for USB, serial, parallel (if you install a version of windows ancient enough to support parallel ports) and ethernet if memory serves. No wifi though.<p>I loved developing like that.

It&#x27;s great to see all the new approaches in this field. IMHO animated interactive visualization of the current flow is pretty to look at, but beyond a certain early point in one&#x27;s understanding of voltage &amp; current relationships, it&#x27;s not necessarily more useful than not being there at all (and having non-interactive access only).<p>For a CS analogy: when you&#x27;re trying to teach how and why to balance a binary search tree, it&#x27;s useful to visually draw out the trees of the first few example steps. However, after you understand the concepts and the invariants, it would be rather unhelpful (or even distracting) to have an animated drawing of the tree as the algorithm progresses every time you were working with a BST!<p>Disclosure -- I wrote CircuitLab <a href="https:&#x2F;&#x2F;www.circuitlab.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.circuitlab.com&#x2F;</a> -- another browser-based circuit simulator and schematic capture tool which doesn&#x27;t do animated graphs, but instead includes:<p>* algebraically-defined behavioral sources (the ability to define voltage&#x2F;current relations as an expression, like a spreadsheet or programming language)<p>* extended-precision numerical core (simulates circuits that make SPICE variants choke) <a href="http:&#x2F;&#x2F;www.edn.com&#x2F;design&#x2F;analog&#x2F;4418707&#x2F;1&#x2F;Extended-precision-simulation-cures-SPICE-convergence-problems" rel="nofollow">http:&#x2F;&#x2F;www.edn.com&#x2F;design&#x2F;analog&#x2F;4418707&#x2F;1&#x2F;Extended-precisio...</a><p>* frequency-domain analysis (Bode plots)<p>* parametric simulation sweeps over any parameter in any element<p>* export publication-quality vector PDF&#x2F;EPS&#x2F;SVG and raster PNGs of your schematics<p>* easily add custom elements with pins to represent any stuff you like (connectors, modules, etc)<p>* pure JS solution, or more specifically, CoffeeScript compiled to JS -- the creator of CoffeeScript said &quot;an order of magnitude more [lines of code] than I&#x27;ve ever dealt with in a single project&quot; <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=3644662" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=3644662</a> (and the LOC count has grown substantially since that comment!)

Yet another app in the cloud that would work much better as a standalone software. It looks nice but I won&#x27;t invest time learning software that may disappear with the company, is closed source and crippleware to boot.

Wow. The graphics are beautiful. The simulation is pretty standard; LTSpice can do most of the things this can. But the UI is nowhere near as good looking.<p>There&#x27;s a nice feature - it tells you when you overloaded a component. LTSpice, for some reason, does not do this, even though the models and the simulation have the info to detect overload.

There are a number of cool online circuit simulation tools and some are quite powerful.<p>Full disclosure: i am on the team building Multisim Live (<a href="https:&#x2F;&#x2F;beta.multisim.com" rel="nofollow">https:&#x2F;&#x2F;beta.multisim.com</a>) which is in this space.

The interactivity features are awesome. For non-interactive online simulation though I use <a href="https:&#x2F;&#x2F;www.partsim.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.partsim.com&#x2F;</a> , which has a clunky UI but gives you the freedom to use SPICE.

If you happen to play Minecraft, you should also take a look at <a href="https:&#x2F;&#x2F;electrical-age.net&#x2F;" rel="nofollow">https:&#x2F;&#x2F;electrical-age.net&#x2F;</a><p>It&#x27;s not my own project -- I work on it, but the bulk of the code was written by an electrical engineer. I can state that it&#x27;s about as good an electrical simulator as you&#x27;re likely to get in that environment, though, which actually means pretty damn good.<p>It also allows for more... interesting worlds to play around in: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=v5kpOQKNxFE" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=v5kpOQKNxFE</a>

This looks interesting. How does it differentiate from other web simulation tools like CircuitLab, Multisim Live, and PartSim?

EC is the best, most intuitive tool, you could use on an android device to simulate complex schematics. I&#x27;ve designed some of my best hifi amplifiers in EC. I warmly recommend it to anyone studying the area of electrical engineering, and to enthusiasts as well. Give it a few years,and you&#x27;ll be pros ;)

If only I had this 30 years ago!!! It was such a voodoo to make a circuit that worked.

Looks very cool, but when I signed up on my phone, I was told that I have a 24 hour trial, after which I would need to pay $15. There didn&#x27;t seem to be any indication of this before I started.

I started learning basic electronics circuits and arduino. I am using <a href="https:&#x2F;&#x2F;circuits.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;circuits.io&#x2F;</a> which is also nice tool .

what kind of platform was used to develop this? Cool to see it running in the browser and on mobile.

Does anyone know of any hydraulic or pneumatic schematic simulation tools like this? I&#x27;ve been wanting to make something like that for a number of years now, but haven&#x27;t yet had the chance.<p>Also, I&#x27;d be curious to know more about the team behind EveryCircuit, what approach they took to managing simulation logic (eg: discrete vs continuous), and other nitty-gritty engineering details.

How does it compare to <a href="http:&#x2F;&#x2F;icircuitapp.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;icircuitapp.com&#x2F;</a>, an app based on this classical simulation <a href="http:&#x2F;&#x2F;www.falstad.com&#x2F;circuit&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.falstad.com&#x2F;circuit&#x2F;</a> ?

If you are affiliated with <a href="http:&#x2F;&#x2F;everycircuit.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;everycircuit.com&#x2F;</a> please DM me on twitter (@0xbsec) to fix a reflected xss vulnerability. ( tho it&#x27;s obvious so I think you are already notified ).

Has anyone found something similar to this that supports RF&#x2F;Microwave circuits. This could do wonders to teaching the smith chart, matching impedance and so on.<p>Or what&#x27;s the probability this site will add RF in the future?

cool that their functionality improved this much so far.<p>how well does it converge and how accurate are these things? could be pretty useful for simple analog stuff.

This is very much along the lines of (at least the example in) Bret Victor&#x27;s media for thinking the unthinkable. Looks great.

I really need one of these to be able to simulate vacuum tubes!
