A proposal for an app - Electrical Circuit Simulator
CM630:
I am not sure that my topic is appropriate but I believe it will not harm.
I am also not sure that this shall be in this section. :-[
Recently yet another drawing app in Lazarus was announced.
So probably there are people that like making drawing apps.
I am not an optimist that a single person can handle and mantain such an app and make it comparable with for example FreeCad (I use it and it has significat problems).
But years ago I have come across this app: https://veppa.com/ekts/
As far as I understood, it was made (and abandoned) by a student, so it is doable by a single person. It is very useful, it would be even more, if it did not have some serious bugs.
So maybe the next time when somebode decides to do some drawing app, maybe (s)he might consider this idea.
Note: This has nothing to do with P/LT Spice, it about relays, buttons and switches.
zamtmn:
An editor of relay electrical circuits, and ideally a simulator, is one of the goals of the zcad project. But there are a lot of difficulties along the way))
CM630:
Please let me know (maybe PM) when/if there is some progress? I might do some testing.
VisualLab:
I would say that this is quite an ambitious project. It looks like a lot has been done. But there is still a lot to do. In any case, it requires knowledge not only of the basics of electrical engineering but also of the basics of electrical equipment and vector graphics and the operation of graphic controls (editor).

zcad goes a long way in solving that. For electronics just a database needs to be added and their values and that data is readily available for most standard components like resistors, transistors, capacitors, tubes, you name it: that it how we all design our circuits after all. And a couple of classes that solve the min/max values of those components. A working example should not be too difficult, just labour intensive.
I used to build tube guitar amplifiers like that. (and got shocked multiple times, so don't trust me! high voltage dc is not the fun part of ac/dc. Cause: usually self build trafo's)
