Because of the Pi's usage in electronics projects, we have a few questions related to connecting the Pi to various circuitry, which occasionally will require diagrams to demonstrate how it could work.

So should we have a (Circuit Labs) Schematics function, similar to those used on EE (see here)?

As far as I remember, I think most users currently do circuit diagrams using codeblocks, vague photos, screenshots of schematic programs (e.g. Fritzing).... I gave up trying this on one question and just screenshotted EE's question editor :-/

Also, would this have problems with software licensing etc?

Users on other sites like Arduino (A51), DIY seem to want it as well. It also seems to be available on Amateur Radio (Beta).

Similar question on MathJax support. Also EE's feature request.

I thought this had already been asked here (might have been another site), but I couldn't find any questions on it....

  • Playing devils advocate this would seem to be directed at those above the level of most in our community. It is more than I would expect a noobie to use or understand, which means that it would be of limited use for those answering questions too. For example which diode do I choose? What if any are the differences between these diodes? Commented Dec 14, 2015 at 2:44

    I tested it on EE and would dare to say that it is quite intiutive to use. The diodes example comes up with the setting 1N4148, call it a generic diode if you will. The selection of the component is really separate from drawing of the schematics. Actually it should be the part where EE comes into play.

    @SteveRobillard, as said over there, I hope you don't mind taking that example to make a case pro schematics editor. I argue that such schematics could be as easily made in the online editor as used on EE - without leaving the browser, finding some graphics editor, saving and uploading the image... (negative side: we'd loose hand drawn arrows and the certain flair that comes along).

  • No I don't mind you using my MS Paint drawing as an example. +1 for pointing out the negative of fancy schematics. You may want to copy my image here and then draw up a schematic for easy side by side comparison. Commented Dec 17, 2015 at 15:33
  • @Wilf, it's active! See meta.raspberrypi.stackexchange.com/questions/701/… Since you brought it up, care to write a short introduction? It might just fit well our upcomming blog.

  • This was an excellent idea, and it's good to have it. The issue now seems to be getting people to use it. I've posted this link in maybe 100 comments to questions where a schematic would benefit the OP, and AFAIK it has not yielded one schematic addition.

YES we should, this would be useful!

Not sure but we may need examples to prove we need this, plz comment or something if u spot em!

  • MAYBE we do need this for sake of easy-of-use, and it might help with migration to and from EESE if we use the same drawing system however I'm equally likely to upload an image (or potentially even simple files - built using the default component libraries) from the GP Licensed GEDA project's gschem schematic drawing program which anyone can access/use - obviously such contributions will fall under the CC-BY-SA terms of this site.

NO (I like drawing things myself)
