REDSTONEPEDIA › Circuits

Circuits

The classic redstone contraptions, one collection each. Each page says what it does, what it takes and how to build it, and lets you try it in 3D.

One short pulse from a lever, long presses cut short, quick blips stretched.

Toggle switches (T‑flip‑flops)

One button that turns things on, then off.

The same signal, a set number of ticks later.

AND, OR, NOT, XOR: a door that needs two levers, a light switched from both ends.

Memory and counters

Remember an event until reset, or react on every 2nd, 3rd... pulse.

Piston extenders

Push a block 2 to 12 blocks out and pull it back exactly.

Flying machines

Machines that fly by themselves: trains, tree farms, world eaters.

Shulker box loaders and unloaders

Box a farm's output into shulker boxes, or unpack them into storage.

Endless lit TNT, without crafting any.

Block change detectors (BUD switches)

Notice a block placed, removed or grown next to it.

Timers and pulse multipliers

One-shot timers, stay-on timers, several pulses per press, clock dividers.

Sort mixed items into chests, one kind per slice, slices side by side.

Combination locks

Open a door only when every item frame shows its code, or when its buttons are pressed in the right order.

Show a container's fill level as a 7-segment digit, 0 to 9.

Add bits: half adders, full adders, and slices that chain into any width.

One press lights one of several outputs at random: coin flips, dice, lotteries.

Furnaces fed from one input chest and one fuel chest, every result in one chest.

Brewing stands fed from chests, wart then sugar in order, finished potions in one chest.

Auto-composters

Composters fed from a farm's hopper line, one crop a slice, the bone meal in chests.

Lift items N blocks up from a chest into a chest, as fast as a hopper feeds them.

Minecart stations

Stop a cart at the platform, send it on with a button; load and unload hopper minecarts; carry a chest's items far away.

Crafters that craft by themselves from a supply chest: iron blocks, crafting tables, sticks.

Automatic doors

A 2×2 piston door that opens by itself as you walk up and closes behind you.

Bedrock breakers

Remove the Nether roof's bedrock with one key press, armed every 6 ticks.
