Copper bulb is a special redstone component and light source block you can make with three copper blocks of the same oxidation stage, one redstone dust, one blaze rod and a crafting table in Minecraft 1.21. They also generate in trial chambers. This block emits light according to its oxidation level, the more it's oxidized the less light it gives off. You can only activate and deactivate the copper bulb when it receives redstone signal. While powered, comparators can output a redstone signal of 15 from a copper bulb.

Crafter is the Minecraft 1.21 revolutionary block that introduced auto-crafting to the game. It's fairly expensive as it requires five iron ingots, two crafting tables, two redstone dust and one dropper. It allows you to make both simple and complex items by disabling the cells inside it. The crafter will only work once it received redstone power. So, it's best to connect it to a redstone clock. It shoots out items from the front side only and you can place a chest in front so all items will end up in there.

Trial chambers are unique underground structures that are mostly made up of tuff and copper blocks in Minecraft. These structures generate in the deepslate layers, but not too deep. Mobs you'll encounter are chosen randomly from four categories. They are spawned by trial spawners and can be ranged, melee, small melee and the Breeze. You can get loot from various sources, be it chests, decorated pots, barrels, dispensers, trial spawners, vaults and ominous vaults.
