Seems like this mod is no longer in active development. The redstone interface is easily the best mod object in the entire world for setting up redstone light systems - I can't find an equivalent in 1.20.1+. I'd love to see - at the bare minimum - this part of the mod updated, and ideally with the ability to be camouflaged. I may fork it myself if nothing happens.

I miss this mod - definitely an era-defining mod in MC history.
