CU later
My take on a datapack that replaces redstone component's iron with copper (and some other tweaks)

About this Mod
Been wanting to give copper a more meaningful purpose?
with this pack all blocks that are considered "redstone components" have copper in their recipes
recipes that has been changed:
- rails (most types), hoppers, tripwire hook and pistons: requires copper ingots instead of iron
- powered rails: requires 4 copper ingots and 2 gold ingots
- crafters: still need some iron for its recipe
there is also a resourcepack build in to reflect the changes
(high chance that this most likely can cause some conflicts and compatiblity issues)
