You don't need to be an engineer to use redstone. These ten ideas cover most farms, doors and contraptions you'll ever build.
Post your first redstone build – even if it's just a door that only opens sometimes.
The parts
- Redstone dust: carries power up to 15 blocks.
- Repeater: refreshes the signal to full strength, adds a delay (1–4 ticks) and only works one way.
- Comparator: compares two signals or reads how full a chest, furnace or hopper is.
- Redstone torch: is on by default and turns off when the block it's on gets power.
- Observer: sends a short pulse when the block in front of it changes.
- Piston / Sticky piston: pushes (and pulls) blocks.
The 10 circuits
- NOT gate – a torch on a powered block: power in = power out off.
- OR gate – two lines of dust that join. Either input turns it on.
- AND gate – both inputs must be on (two torches on blocks feeding a third torch).
- Repeater delay line – chains of repeaters for timing doors and traps.
- Clock – a signal that turns on and off by itself; two observers facing each other is the simplest.
- Pulse limiter – turns a long signal into a short one (an observer watching a lamp works).
- T flip-flop – one button press = on, next press = off (great for lights).
- Item sorter – a hopper line with comparators that pulls one item type out of the stream.
- Hidden piston door – the classic 2×2 piston door.
- Auto-farm trigger – an observer watching sugar cane or pumpkins that fires a piston when they grow.
Tips
- Build in a creative test world first.
- Dust only powers what it points at; if a lamp doesn't light, check the direction.
- Some designs work differently on Java and Bedrock (quasi-connectivity is Java only). Check the edition when you copy a build.
