RAW MATERIALS NEEDED
Recipes this calculator uses
Every item is expanded down to raw, mined materials using the vanilla Java Edition recipes below.
| Item | Ingredients per craft |
|---|---|
| Piston | 3 planks, 4 cobblestone, 1 iron ingot, 1 redstone dust |
| Redstone Repeater | 2 redstone torches, 1 redstone dust, 3 stone |
| Observer | 6 cobblestone, 2 redstone dust, 1 nether quartz |
| Dropper | 7 cobblestone, 1 redstone dust |
| Hopper | 5 iron ingots, 1 chest |
| Intermediates | 1 log makes 4 planks; 2 planks make 4 sticks; redstone torch = 1 redstone dust + 1 stick; chest = 8 planks; stone = smelt 1 cobblestone; iron ingot = smelt 1 raw iron |
Worked example: 10,000 Pistons
40,000 cobblestone, 10,000 raw iron, 10,000 redstone dust and 7,500 logs. The planks (30,000) are crafted in batches of 4, which is why 7,500 logs are needed.
? How this is calculated
Each item's full crafting tree is expanded recursively down to raw, mined materials
(cobblestone, redstone dust, nether quartz, raw iron, logs) using the actual vanilla
recipes and output counts — for example, 1 log makes 4 planks, 2 planks make 4 sticks, and
smelting 1 cobblestone makes 1 stone. Because most recipes don't produce exactly 1 item per
craft, the number of times you need to craft something is rounded up to the
next whole craft (needing 10 sticks means crafting 3 times for 12, since each craft makes 4),
and that rounding carries through the rest of the tree. The crafting-order checklist lists
every intermediate item deepest-dependency-first — planks and sticks before the things that
use them — so following it top to bottom never asks you to craft something before its own
ingredients exist. Checked-off steps are saved in this browser only, per item and quantity.
