I want to ask a quick question, and think a circuit diagram would make it a bit clearer, but I don't have any software for knocking one up, is there a recommended online tool I could use? It only needs a few simple symbols, it doesn't need to export (I could screen-shot it).
Then I can host the image on twitpic or similar, and include it in the body of my question.
Otherwise I'm going to draw it in paint!
PS - for this stack exchange site, it would be awesome to have a diagram tool built into the site, but if there is a free online tool, it might be worth reccomending it in the faq (just below where it says:)
