Delay (delay line)
2-tick delay · 2 blocks
Whatever goes into the input comes out 2 ticks (0.1 s) later, every pulse the same length.
made of repeater · fits in 1×2×1
9 versions, 2 to 13 ticks
Every size 9
The best design for each size: pick one to see it.
| size | blocks | numbers |
|---|---|---|
| 2 ticks (0.1 s) (this page) | 2 blocks | needs an input of at least 2 ticks (0.1 s) · two pulses 2 ticks (0.1 s) apart stay separate |
| 4 ticks (0.2 s) | 2 blocks | needs an input of at least 4 ticks (0.2 s) · two pulses 4 ticks (0.2 s) apart stay separate |
| 5 ticks (0.25 s) | 11 blocks | needs an input of at least 6 ticks (0.3 s) · two pulses 5 ticks (0.25 s) apart stay separate |
| 6 ticks (0.3 s) | 2 blocks | needs an input of at least 6 ticks (0.3 s) · two pulses 6 ticks (0.3 s) apart stay separate |
| 7 ticks (0.35 s) | 10 blocks | needs an input of at least 6 ticks (0.3 s) · two pulses 5 ticks (0.25 s) apart stay separate |
| 8 ticks (0.4 s) | 2 blocks | needs an input of at least 8 ticks (0.4 s) · two pulses 8 ticks (0.4 s) apart stay separate |
| 9 ticks (0.45 s) | 10 blocks | needs an input of at least 6 ticks (0.3 s) · two pulses 5 ticks (0.25 s) apart stay separate |
| 11 ticks (0.55 s) | 10 blocks | needs an input of at least 8 ticks (0.4 s) · two pulses 5 ticks (0.25 s) apart stay separate |
| 13 ticks (0.65 s) | 10 blocks | needs an input of at least 10 ticks (0.5 s) · two pulses 8 ticks (0.4 s) apart stay separate |
Try it
Hold IN under the view for a long press, tap it for a short one: the box marked OUT turns red while the output is on. Press play under the view to watch a demo on a loop; touch any other control to take over.
How this design does it: One repeater set to 1: the signal comes out 2 ticks later.
Build it
Download .litematic Download the design as text
The .litematic opens in Litematica (Minecraft 26.3): every block of the design in one region. The text file is the same build written as plain text, block by block.
Details: how it works, measurements and properties
In depth
The output is a copy of the input, N = 2 ticks (0.1 s) later: a pulse goes in, the same pulse comes out N later, same length.
Pulses shorter than 2 ticks (0.1 s) (the shortest a real input makes) get lost. Two pulses closer than 2 ticks (0.1 s) (the shortest a real input makes) merge.
How to try it
Press play under the view to watch the demo on a loop (the badge reads demo with the step it is on; the same sequence is drawn as a timing diagram below). Touch any control to stop it and try the circuit yourself.
To try it: press and hold the IN button of the bar (or the cell tagged IN) to power that input; a quick tap sends a short 2-tick pulse.
Inputs are tagged in lime; the output is tagged OUT: the orange glass marker next to it glows while the output is on (the output strip by the demo badge shows its last 40 game ticks, 2 seconds). Drag to look around, pinch or scroll to zoom, step one game tick at a time with the step button.
Inputs and output over time
The input follows this schedule (the 3D view's demo plays the same). Lime: an input is on; orange: the output is on (taller = a stronger signal, 1 to 15). Time runs left to right in game ticks (20 ticks = 1 s).
Swipe the diagram sideways: the whole sequence lasts 1104 ticks (55.2 s).

Measurements
| metric | value | what it means |
|---|---|---|
| N | 2 ticks (0.1 s) | the delay: how much later the output copies the input |
| min-pulse | 2 ticks (0.1 s) (the shortest a real input makes) | the shortest input pulse handled correctly (every longer one works too) |
| min-gap | 2 ticks (0.1 s) (the shortest a real input makes) | the shortest gap between two input pulses that still comes out as two pulses |
| tileable | every 1 (0 0 1) |
Notes from its designer
One repeater set to 1: the signal comes out 2 ticks later. Each repeater adds 2 ticks per notch of its setting, so any even delay is a line of them, 2 blocks (repeater + stone) per started 8 ticks
