Found a Lighthouse in my closet! Still useful?

Back in 2015/2016 I ordered a Lighthouse. Apparently, I never got around to setting it up, and I found it, still in the box, in my closet today! I was pretty stoked to see it and remember the project.

I was just wondering if this is still viable today, and if there was anything left of the knowledgebase for it, as the pages have all seemed to have move away from to I totally understand this is quite old and lots of things have changed, but it would be amazing to get it up and running again for nostalgia.

Sadly, there is no longer a compatible beam for the Lighthouse. Sorry about that.
