Raspberry Pi Control, Octoprint, Cura, LEDs, Web Cams, Web Interface, Smoke Detector

This Forums is awesome. It has tons of infos, lots of urls to external projects and very helpful people. Really nice!

Recently I’ve been looking at these posts:

These are really good sources for inspiration, however since the posts are rather old, the urls are long gone and I wonder whether one could take the trouble to repost their settings/setups.

Would you guys share the infos on hardware (LEDs, Web Cam, which RPI, which smoke detector) , software (OS, Versions of software, URLs to download/install to cura, octaprint), and installation instructions/wikis? Can you also share cura settings for the printer?
