While we're on the subject, allow me to plug Electrical Age: https://electrical-age.net/ It's a minecraft mod, yes. It's also a fully functional DC electrical simulation, with realism as a primary focus. Any inaccuracies are either strictly required (= it runs at 20Hz for most purposes), or allowances for decent gameplay. (Or bugs. Those are probably my fault.)

It's a very nice mod. I love designing systems in modded Minecraft, it's very fun and relaxing.

Don't discount your mod because it's made for Minecraft, this looks like a lot of fun!

Nice site!

That example circuit is called a resonant circuit and the oscillation that is seen after the power supply is removed happens because both the capacitor (C) and the inductor (or coil, L) store energy—in electric and magnetic fields, respectively—and start feeding each other.

How do I get the scope output for circuits that I build?

You can add scope plots by right-clicking on any component and selecting "View in scope".

I designed an actual board with this. Would have been SOL without it.

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.

If you don't mind using a desktop app, there are still many great tools for hobbyists and for teaching. Recently I've used: Qucs: https://sourceforge.net/projects/qucs/ Circuitmod: https://sourceforge.net/projects/circuitmod These were also in my bookmarks of tools I've explored: CEDAR Logic Simulator: https://sourceforge.net/projects/cedarlogic Logisim: https://sourceforge.net/projects/circuit/ For teaching LogicWor…

KiCAD 5 was recently released (congrats team!) and it got ngspice integration which sounds neat. Haven't yet had time to try it out, but what I've seen so far looks promising. Of course with SPICE (and really any simulator) the problem is creating/finding good models for your parts or even generic ones.

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.

Thanks for building that. Awesome piece of software. Helped me a lot when I was dabbling in hardware coming from software.

This tool is the lowest-barrier-to-entry to get into circuit design -- used the applet after trying commercial/trial tools (including "cloud-based" ones), and all failed me.
