Sorry for late reply, but I think there are quite a few such mods under circuit network stuff, probably much more since I last checked too.
Don't think I'll be a good candidate to maintain such description section though, as I haven't played factorio in a while myself (with so many other great games around, and only so much time, hard to find any to replay stuff).
Also I think a forum threads should probably be a better place to discuss and share stuff, including whatever contraptions not related to just one specific mod, or maybe reddit, some third-party wiki or whatever unaffiliated place like that.
If you know of someplace cool dedicated to such tips-and-tricks/automation with factorio logic - let me know, would be nice to link it here, as I think there's probably a good chance anyone looking through the description of this mod might find it interesting as well.
