## Instructions - Target Java 1.21+ mechanics; note Bedrock quirks separately, default to Java timings (2 gameticks per redstone tick). - Master basics: dust power 0-15, repeaters lock/delay, comparators subtract/measure containers, observers 2-tick pulse. - Use hopper clocks for slow timers, etho clocks for compact loops, daylight sensors for day-gated farms. - Build pistons as quasi-connectivity aware (Java): sticky pull 1 block, 12-block push limit, slime/honey move-point. - Build item sorter with 41-1-1-1-1 filter (41 filler + 4 renamed); overflow chest + locked hopper cutoff. - Size super-smelters as furnace/minecart-hopper chains: 12 furnaces fed by 2 hopper lines, fuel auto-refill via sorter. - Quote farm rates honestly: iron golem 30-40 ingots/hr per cell, gold piglin 200-400 nuggets/hr, slime 800/hr. - Light-proof mob farms (light 0), spawn-proof surroundings 128-block radius for max rates; AFK at 24-120 blocks. - Chunk-load with nether portal chunk loaders or /forceload on servers; avoid breaking locators on unload. - Debug with F3 + alt-F3 timings, carpet mod tick freeze, and Litematica schematics for rebuilds. - Complements minecraft-survival skill for early game; use this for automation mid/late game scaling. - Backup world before large piston door or flying machine tests to avoid chunk corruption. ## Examples - Example 1: "auto sorter overflowing" -> check 41-stack filter renamed, hopper locked via torch, overflow chest not full. - Example 2: "iron farm slow" -> verify 3 villagers + zombie scare 8-block, beds claimed, golem spawn 8x8x6 clear. - Example 3: "super smelter uneven" -> balance input minecart hoppers, add fuel comparator cutoff at 64 coal blocks. ## Workflows - Sorter workflow: Place chest->hopper chain -> comparator filter hoppers with 41 filler -> torch lock -> test stackable + shulker. - Clock workflow: Choose period (hopper 8min full, repeater loop <10s) -> build -> measure with hopper counter -> tune. - Iron farm workflow: Villager pods (3 beds/workstations) -> zombie chamber line-of-sight toggle -> kill lava 2x3 -> collection sorter. - Debug workflow: Isolate circuit in creative copy -> tick freeze -> step observer outputs -> fix quasi power -> rebuild survival. ## Templates - Sorter slice checklist: - [ ] Bottom hopper locked when redstone torch ON - [ ] Filter: slot1=41 named cobble, slots2-5=1 target item - [ ] Comparator out of filter hopper into repeater - [ ] Overflow chest at end + lava trash for junk - Hopper clock recipe: 2 hoppers locked into each other + comparator each + 1 item = ~8s; full stack = ~4min. - Smelter column: Input chest -> hopper -> furnace top, fuel chest -> hopper -> furnace side, bottom hopper -> output chest. - Rates table: Iron 1-cell 35/h | Gold 4-portal 350/h | Cactus 1200/h | Bamboo 900/h | Slime 700/h. ## Tools - Mods: Litematica, MiniHUD, Carpet, TickProfiler, Litematica printer (creative). - Calculators: hopper speed 2.5 items/s, furnace 10s/item, minecart-hopper 8x faster. - Seeds/maps: chunkbase.com for slime chunks, iron finder overlay. - Servers: Paper timings for lag check, /tps, spark profiler for farm impact. ## Advanced - Build 0-tick pistons (Java) for instant sugarcane harvest; patch-check per version as Mojang fixes. - Use update suppression sparingly; document version as it breaks across 1.20-1.21. - Stack raid + witch + gold farms with nether portal item transport for trading halls. - Implement shulker unloader with comparator 1-signal + breaker to auto-refill building projects. - Mute lag with entity cramming caps + composters to convert excess to bonemeal. - Chain flying machines with 2-way slime engines for tunnel bores; stop with obsidian catchers. - Add overflow-proof cactus + bamboo auto-crafters feeding composter bonemeal loop for moss farms. - Document per-farm on/off toggles with labeled levers to prevent server lag complaints. ## Documentation - Wiki redstone: https://minecraft.wiki/w/Redstone_circuit - Tutorials: https://minecraft.wiki/w/Tutorials/Redstone_machines - Farm rates: https://minecraft.wiki/w/Tutorials/Iron_golem_farming - Carpet docs: https://github.com/gnembon/fabric-carpet/wiki - Storage tech: https://minecraft.wiki/w/Tutorials/Storage_minecarts - Slime finder: https://chunkbase.com/apps/slime-finder - Java parity: https://minecraft.wiki/w/Java_Edition_mentioned_features
