Redstone
Comparator logic, update order, clock design: redstone treated as an engineering discipline, with circuits you can copy.
redstoneEnder pearl chunk loaders in 26.3: stasis chambers, what they load, and why your farm still stops
Since 1.21.2 a thrown ender pearl keeps its chunk loaded, which turned the stasis chamber into the cheapest chunk loader in the game. What it actually loads (one full chunk, eight lazy ones), why it vanishes when you log out, how it compares to a portal loader, and which farms it can and cannot keep running.
redstoneCopper golem sorting, explained: the exact rules behind redstone-free item sorting
A copper golem sorts items without a single piece of redstone, but only if you build around how it actually thinks: a 65 x 17 x 65 search area, a reach of 1 block up and 2 down, 3 seconds per chest, and a memory of 9 chests. The exact rules, and a storage layout that works with them.
redstoneAuto-crafting with the Crafter block in Minecraft 26.3
The Crafter turns crafting into a redstone component: a 3x3 grid you wire like any other block. The entire trick is disabling slots, and once that clicks you can automate almost any recipe.
redstoneRedstone on Bedrock: why Java circuits break and what actually differs
Bedrock redstone is not Java redstone with a different skin. It runs a two-phase tick system, keeps block updates and redstone signal as separate systems, and drops quasi-connectivity entirely. Here is what that actually changes for piston doors, sorters, BUD switches, and clocks, and where Bedrock comes out ahead.
redstoneRedstone clocks explained: repeater, hopper, and comparator clocks in Minecraft 26.2
A redstone clock is any circuit that turns itself on and off forever. There are three you should actually know, each tuned to a different speed and purpose. Pick the wrong one and you either lag your world or wait all day.
redstoneThe redstone repeater: delay, locking, and diode behavior in Minecraft 26.2
The repeater is the first real redstone component most players place, and also the one they understand least. It does three jobs at once: it repeats, it delays, and it locks. Learn all three and long-distance redstone stops being a mystery.
redstoneThe complete redstone handbook for Minecraft 26.2
The single redstone reference to bookmark. Every component, every signal strength, every clock, and the core circuits, with exact tick timings for Minecraft 26.2 Java.
redstoneBuilding an item sorter in Minecraft 26.2: hopper logic explained
Item sorters look like magic, but every one runs on the same hopper trick: a row of overstacked filter items the comparator never quite empties. Here is how that logic works and how to build it cleanly.
redstonePiston doors in Minecraft 26.2: 2x2, 3x3, and hidden designs
A piston door is the redstone build everyone wants and most people give up on. The trick is understanding push limits, sticky pistons, and update order before you ever place a block. Here is how each size really works.
redstoneThe redstone comparator and signal strength in Minecraft 26.2
The comparator is the most misunderstood block in redstone. It does two completely different jobs depending on one torch, and it can read the contents of a chest. Once signal strength clicks, half of redstone opens up.
redstoneHow to build a mob switch in Minecraft 26.2: disable hostile mob spawning globally
A mob switch fills the global hostile mob cap with permanently loaded, harmless mobs, which stops all hostile mob spawning in the overworld. Here is how the mob cap works, why the switch works, and two designs that work in 26.2.
redstoneHow 18 digits create an infinite universe: Minecraft seeds and world generation, fully explained
Every Minecraft world that has ever existed was already there before anyone pressed "Create New World." A single 64-bit number addresses one universe out of about 18.4 quintillion. Here is how the math works, why the title screen seed took four years to find, and what it means philosophically.
redstoneObserver clocks, BUD switches, and quasi-connectivity: Minecraft redstone explained
Quasi-connectivity is a bug Mojang chose not to fix. BUD switches exploit it. Observers made it irrelevant for most uses, but knowing the difference lets you build things neither tool alone can do.
redstoneWhy your redstone breaks on chunk borders in Minecraft 26.2 (and how to fix it)
Pistons stall, hoppers freeze, mob farms die. Chunk borders are the silent killer of redstone in 1.21. The good news is the fix is usually one /forceload away.
