Delay (delay line)
11-tick delay · 10 blocks
Whatever goes into the input comes out 11 ticks (0.55 s) later, every pulse the same length.
needs an input of at least 8 ticks (0.4 s) · two pulses 5 ticks (0.25 s) apart stay separate · made of redstone block, repeater, sticky piston · fits in 7×2×6
Every size 9

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: Delay line, 11 ticks, 10 blocks: the odd delays a repeater line cannot make.
Build it

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.
Blocks used: redstone block repeater sticky piston stone
Details: how it works, measurements and properties
In depth
The output is a copy of the input, N = 11 ticks (0.55 s) later: a pulse goes in, the same pulse comes out N later, same length.
Pulses shorter than 8 ticks (0.4 s) get lost. Two pulses closer than 5 ticks (0.25 s) 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 redstone lamp in that cell (the view adds it to show the output) lights 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 1204 ticks (1 min 0.2 s).

Measurements
| metric | value | what it means |
|---|---|---|
| N | 11 ticks (0.55 s) | the delay: how much later the output copies the input |
| min-pulse | 8 ticks (0.4 s) | the shortest input pulse handled correctly (every longer one works too) |
| min-gap | 5 ticks (0.25 s) | the shortest gap between two input pulses that still comes out as two pulses |
Notes from its designer
Delay line, 11 ticks, 10 blocks: the odd delays a repeater line cannot make. Two stages of two sticky pistons with redstone blocks, joined by a repeater set to 3. In each stage the first piston pushes its block against the second piston, which pulls its own block away from the next part. A piston set off by a block ARRIVING acts one tick later than one set off by a signal, so each stage takes 3 ticks one way and 2 the other, and inverts; two stages in a row add up to the same odd number on both edges.
