Redstone Clock
A single Redstone Clock block that emits a repeating, adjustable redstone pulse. Place it, tap it to set how fast it ticks, wire it to whatever you want pulsed — a lamp, a piston, a dropper, a Crafter — and you're done. No repeater loops, no observer contraptions, no redstone-engineering degree required.
One block, does the whole job
Vanilla has no simple clock block — you normally build one out of repeaters or observers. This is that clock in a single, configurable block.
Crafting
Crafted at a vanilla crafting table. Recipe unlock: having a redstone torch in your inventory.
How to use it
- Place it anywhere you'd put a normal block. It starts ticking immediately at its defaults: a 1-second interval, in short-pulse mode, running.
- Configure it: tap/use the block (right-click, or tap on touch) to open its settings menu.
- Wire it up: any redstone component touching the block reacts to the pulse — lamp, piston, dropper, dispenser, Crafter, or redstone dust running away from it.
The clock's face lights up brighter each time it fires, so you can see it working from across the room — even before you've wired anything to it.
Settings
Tapping the clock opens a small menu with three controls:
| Setting | What it does |
|---|---|
| Interval (seconds) | A slider from 1 to 60 seconds — the length of one full on/off cycle. |
| Pulse shape | Short pulse (a brief blip once per cycle) or Square wave (on for half the cycle, off for half). |
| Running | Turn the clock on or off. Off = quiet and greyed out, but it remembers your settings. |
Which pulse shape do I want?
- Short pulse (the default) fires one quick tick per cycle — perfect for a Crafter, dropper, or dispenser, which act once per redstone pulse.
- Square wave stays on for half the cycle — better for a blinking lamp or anything you want held on for a while, then off for a while.
Wiring it up
- Anything touching the clock — a lamp, piston, Crafter, or redstone dust on the ground beside it — reacts to the pulse directly.
- Dust on top of a block works if that block is sitting directly on top of the clock: the clock strongly powers the block above it (like a redstone torch does), so dust on that block carries the signal. Dust on a block beside the clock will not — put your relay block on top.
Line up a bank of them
Every clock set to the same interval blinks in perfect sync, no matter when you placed it. Rows of same-speed clocks (or lamps they drive) pulse together automatically — handy for decorative lighting or synchronized farms.
Good to know
- Breaking a clock drops it back as an item, but a freshly placed clock starts at the defaults again — settings don't carry over a break-and-replace. Set it once it's in position.
- Settings survive restarts, reloads, and wandering far away and back — a placed clock keeps its configuration as long as it stays placed.
- Fastest useful pulse is 1 second. That's plenty for lamps, farms, and Crafters without the timing jank that ultra-fast clocks cause.
