Power Sources
Blocks that generate redstone signals on their own or through player interaction.
13 componentsTransmission
Blocks and items that carry, modify, or redirect redstone signals.
3 componentsMechanical
Blocks that convert redstone signals into physical movement or action.
12 componentsTriggers
Blocks that detect events and output redstone signals in response.
9 componentsKey Components
Redstone Repeater
Extends, delays, and isolates redstone signals. Refreshes signal back to 15 regardless of input strength. Adjustable delay from 1 to 4 ticks. Can be locked by powering its side.
Redstone Comparator
A versatile component with two modes: compare mode (outputs back signal if back >= side) and subtract mode (outputs back - side). Can also read container fullness as an analog signal.
Observer
Detects block state changes in front of its face and emits a 1-tick pulse from its back. Detects placement, removal, growth, state changes, and more.
Sticky Piston
Like a regular piston but pulls the attached block back when retracting. Essential for doors, drawbridges, and any mechanism that needs blocks to return to their original position.
Piston
Extends when powered, pushing up to 12 blocks in its facing direction. Cannot push obsidian, bedrock, or extended pistons. Does not pull blocks back when retracting.
Hopper
Collects items from above and transfers them to the container it points at. Can be locked (disabled) with a redstone signal. Transfers 1 item every 8 game ticks (0.4 seconds).
Dispenser
A block that dispenses items when powered. Behavior depends on the item: shoots arrows/eggs/potions, places water/lava, equips armor on players, etc. Has 9 inventory slots.
Sculk Sensor
A wireless redstone component that detects vibrations (footsteps, block placement, etc.) within a 9-block radius and outputs a redstone signal. Different vibrations produce different signal strengths.
