OP cobblestone farm - fully automatic

Important note : Orange concrete is a placeholder for lava and all ice must be broken, and all leaves must be waterlogged.

This fully automatic cobblestone farm delivers massive resource yields by combining lava-water generation with a dense grid of automated breaking mechanisms. Built for Minecraft 1.21.11, the entire installation measures 37 by 37 blocks wide and 26 blocks high, resting on a sturdy obsidian and ice foundation.

Design and Mechanism

The automated core relies on 336 pistons, 96 observers, and 32 note blocks working in tandem to generate and mine stone simultaneously across a sprawling multi-module array. Powered rails, redstone wire, and redstone torches weave across the top platform to coordinate the timing, while droppers and tripwire components manage material flow. The structure is built primarily from cobblestone, orange concrete, spruce leaves, and black stained glass, creating an industrial aesthetic that keeps the complex wiring neatly organized.

Placement and Operation

• Drop this schematic into your world on a flat platform with a clear perimeter to allow uninterrupted redstone processing.
• Ensure you supply the necessary lava and water sources to feed the stone generation points beneath the piston arrays.
• The build is vanilla-friendly and requires no mods, making it easy to drop straight into a survival world to solve all your stone-building needs.
