alt Hacker NewsAre there similar solutions without 3d view? I want to get a simulator that can show me what is going in the circuit, ideally slowed down a lot. For example I was making a dongle with resistor and capacitor which was delivering a pulse-short (i.e. removing power for a short period of time instead of delivering an impulse) and while I was able to confirm overall idea with some online simulator, dialing in capacitance and resistance required physically switching components. Ideally I want to be able simulate such transient effects and arrive at specific numbers ready to be soldered.
And I want it to be free/open-sourse ideally :)

orcad is the commercial classic for doing schematics with a spice backend. (spice is an oss engine out of berkeley for simulating circuits on computers. for dc it just solves the classic nodal analysis and for ac you can feed in things from a fantasy signal generator and capture things at various nodes in the circuit) there's also some pretty cool looking commercial web thing now that also will maintain netlists with real-time prices and will let you swap parts out and set minimum quantities etc.
kicad is the oss orcad, but i never got good at it. (to be fair, orcad was weird to learn as well)
Some people like Everycircuit and Falstad for that.
Not foss but tinkercad circuits (https://www.tinkercad.com/circuits) comes to mind.

Sounds like you are looking for a SPICE like simulator, there are quite a few free/open:
