Redstone Clocks in Minecraft

Verified on server

Ticking generator: the signal turns on and off automatically. Three schematics — from fastest to slowest — with each period measured in ticks.

  • fastest: 6 ticks (0.3 s)

The exit signal returns and turns itself off

Redstone clocks — a schematic where the signal turns on and off: the output returns in a loop and turns itself off. The fastest ones are — two observers Opposite opponents: impulse every 6 ticks (0.3 seconds). Slower with settings — Torch With a repeater (20 ticks period (1 second)) and repeater ring (32 ticks (1.6 s))

On spectators

Marker layer
  • Two observer They look at each other. When one triggers, the second sees it and triggers itself, continuing endlessly. They start automatically as soon as the second one is placed.
  • Exit — dust emitted by any observer: impulse every 2 ticks (0.1 s), once every 6 ticks (0.3 s).
  • Stop — break an observer or move it with a piston.

On a torch

Marker layer
  • Torch on the block it burns and dust spreads through repeater powers this same block — and then goes out. When it goes out — the signal has been sent, the torch reignites.
  • Period sets the repeater. As checked:
Ticking intervalHour period
1torch goes out, clock resets
212 ticks (0.6 s)
316 ticks (0.8 s)
420 ticks (1 second)

A repeater ring

Marker layer
  • Four repeaters arranged in a circle, with dust between them. Pressing the button once sends a signal around the loop — it then continues endlessly.
  • Period — total delay: with four repeaters on 4 ticks, 32 ticks (1.6 seconds) were achieved, signal stays lit for 20 ticks (1 second). Need more time? Add repeaters to the loop.
  • No torch — nothing to burn out. Stop by breaking any repeater.

Which to choose

ClockPeriodWhen to take
On spectators6 ticks (0.3 s)quickly and in two blocks: farms, dispensers
On a torch20 ticks (1 second)flickering light, slow pistons
A repeater ring32 ticks (1.6 seconds).Any long period, triggered by a button press

A tick is 1/20 of a second. A repeater's delay is 2 ticks. All timings are measured on server version 26.3 in ticks. Learn more about ticks — "Ticks in Minecraft".

What is needed: on observers

The ground, stone, and walls around it — any that the schematic does not draw — can be chosen freely.

Frequently asked questions

How to make a clock out of redstone?

The easiest solution is two observers facing each other: each sees the other's signal. The signal triggers once every 6 ticks (0.3 seconds). Slower alternative: a torch on a block and a dust ring sent back to that block via a repeater.

Why do torch clocks stop working?

The torch extinguishes if it has been toggled 8 times within 3 seconds. Place a repeater with a long delay — it will toggle the torch less frequently.

How to make slow clocks?

Redstone loop: each repeater adds up to 4 ticks, and the signal loops endlessly. Tested: a loop of four repeaters set to 4 ticks produced a 32-tick period (1.6 seconds). Need longer? Add more repeaters.

Tested on Minecraft 26.3 server: the mechanism was placed using commands from this page, levers were toggled, and game ticks were counted.
