Redstone circuits/Clock

A clock circuit is a redstone circuit that produces a clock sign : a model of pulses that repeats itself .

introduction

[

]

Clock generators are devices where the output signal is toggling between on and off constantly. The accustomed diagnose x -clock is derived from half of the time period distance, which is besides normally the pulse width. For exercise, a authoritative 5-clock produces the sequence ...11111000001111100000... on the output signal. Using only redstone torches and cable, it is possible to create clocks a short-change as a 4-clock, sometimes by exploiting glitches. Using repeaters or pistons allows easy construction of any clock down to 1-clocks, and other devices can besides be pressed into service. There are besides special circuits called “ rapid pulsers ”, which produce rapid pulses like a 1 click clock, but inconsistently due to torches burning out. indeed, flashlight based rapid pulses can be besides fast for repeaters. even with repeaters in function, 1-clock signals are unmanageable to handle in other circuits, as many components and circuits do not respond in a timely manner. Creating long clocks ( more than a few ticks ) can be more unmanageable, as adding repeaters finally gets unwieldy. however, there are a number of approaches here, which are discussed in a separate section.

Clocks without an explicit toggle can frequently have one retrofitted, by wiring a lever or early switch to the controlling freeze of an inverter, or even to a redstone coil. In general, forcing the delay loop gamey finally stops the clock, but the output may not respond until the current pulse has made its way through the loop. Whether the output gets stopped high or broken depends on the clock and where in the loop players force it. Another option is to use a lever-controlled piston to open or close one of those loops, using either a solid blockage to transmit power, or a engine block of redstone to supply it. While it is n’t much discussed in the circuit builds below, there is one extra concept that is occasionally crucial : Phase. The phase of a run clock is the point it has reached in its motorbike. For example, at one consequence a 5 clock might be 3 ticks into its ON phase, 4 ticks late, it is 2 ticks into its OFF phase. A long-period clock might be noted as 2 minutes past the start of its ON phase. The demand beginning of a bicycle depends on the clock, but it is normally the begin of either the OFF phase or the ON phase. For most cases, phase does n’t matter because they barely need pulses every 7 ticks or indeed. however, in-game computing circuits are more demand, and if they are doing a daily clock, they should care whether the on phase is day or night .

common mullein clock

rapid pulsar

[

redundancy can be used to maintain a 1-clock, tied as the torches burn out ; the resultant role is the alleged “ rapid Pulsar ” ( designs X, Y and ( vertical ) Z ). however, the signal may not be consistent. Device R creates energy in an irregular sequence. It is a variant of the “ rapid Pulsar ” design shown above, except that each torch pulses in an irregular pseudo-random pattern as each flashlight coming on turns the early three ( and itself ) off. occasionally torches burn out for a few seconds ( until reset by a block update ), during which meter other torches blink. As of translation 1.5.1, this is probable to favor one copulate of torches, such as the east and west torches, which blink while the others stay dark. Output can be taken anywhere on the circuit. Although “ pulser ” is the correct spell for any general circuit that produces pulses, the traditional spell of a clock circumference created from short-circuit redstone torches is “ rapid pulsar ” .

Torch loop

[

]

basic 5-clock pulser ( A )
The basic common mullein pulser is the oldest clock circuit in Minecraft, plainly an curious number of inverters ( NOT gates ) joined in a cringle. The blueprint has been largely replaced by repeaters, but hush works. Design A shows a 5-clock, which is the shortest clock that can easily be made this way. Its pulse length can be extended by adding pairs of torches and/or repeaters. Repeaters can be added into the loop, or can replace any pair of inverters. Adding repeaters besides allows even-numbered clocks such as a 10-clock. The sum interval is “ NOT gate count ” + “ repeating firearm sum delay ” .

even blowtorch based 5-clocks can be made more compact, as with designs B and C. however, these have fewer places where repeaters can be inserted without using more distance. Using this method, 1-clocks and 3-clocks are possible, but these are unstable and erratic as the torches regularly “ burn out ”. As with the basic clock, the compact clocks can be extended by making the chain of inverters longer, or with repeaters. A 5-clock can besides be made vertical, as in G .

Design D uses a different method acting to produce a 4-clock. ( A 4-clock is the fastest clock of this screen that does not overload the torches. ) Design E may be obsolete as of version 1.7. By making manipulation of the North/South Quirk, it was potential to produce a more compact 4-clock with a regular on/off pulse width, as seen in blueprint E. This blueprint uses five torches, but if the stack torches are pointed north-south, it has a pulse width of 4 ticks .

Repeater clock

[

]

A clock sign can be generated by introducing a pulse into a coil of repeaters .

Repeater Loop 1-Clock
2×3×2 (12 block volume)
flat, silent
clock output: 1 tick on, 1 tick off
The simplest repeater clock is simply two repeaters connected with redstone dust in a loop.
The tricky part is introducing a 1-tick pulse into the loop. If the pulse is too long, the repeaters are powered permanently and the only way to fix it is to break and then fix the circuit.
A simple solution to this is to use a lever; flipping it on and then off 1 tick later. The most common method seems to be to place a redstone torch next to the clock, then quickly break it. This may take several attempts to do correctly, requiring the clock be broken and fixed between attempts. A more reliable method (shown right) is to place the torch on a powered block (a block of redstone, or any block powered by another torch or other power source) – the torch is on when placed, but turns off 1 tick later because it’s attached to a powered block. The torch and powered block can then be removed, but stopping the clock later still requires breaking it.
Variations: The dust in front of the repeaters can be replaced with blocks to save on redstone.
Additional repeaters can be added to the loop, increasing the clock period. As long as all the repeaters are kept to a 1-tick delay, the pulse remains only 1 tick long no matter how many repeaters are added. If the delay is increased on any of the repeaters, the pulse length increases to match the longest repeater delay.
Switchable Repeater Loop 1-Clock
3×4×2 (24 block volume)
flat, silent (while running)
clock output: 1 tick on, 1 tick off
This repeater loop can be switched on and off, by moving a block to complete or break the circuit loop.
How it works: When the lever turns on (t = 0 redstone ticks), the sticky piston begins to extend. At t=1, the torch turns off, but the left repeater stays powered for 1 more tick. At t=1.5, the piston finishes extending and the moved block gets powered by the left repeater. At t=2, the left repeater turns off. At t=2.5, the right repeater begins to output the power passed to it by the block. From here on, it just continues as a 1-clock until the lever is turned off, breaking the loop.
Repeater Loop 10 Hz Clock
3×4×2 (24 block volume)
flat, silent
clock output: 1 tick on, 0 ticks off
This clock produces a 10 Hz clock signal (10 activations per second) consisting of 1-tick on-pulses separated by 0-tick off-pulses (the off-pulse exists, but it is replaced by an on-pulse in the same game tick).
Start the clock with a 1-tick pulse (for example, by placing a torch on a powered block). Stop the clock by breaking a piece of redstone dust. Alternatively, the switchable method described above may be used.
A 10 Hz clock runs too fast for some redstone components to respond to. Command blocks and note blocks can handle the rapid activation. Doors, trapdoors, and fence gates produce sounds as if being activated and deactivated that quickly, but appear and act as if constantly activated. Pistons act as if constantly activated, but the 0-tick off-pulses produce the flickering appearance of a deactivated piston overlapping the activated piston. Other redstone components simply act as if constantly powered.

Torch-repeater clock

[

]

Since the introduction of the repeater, the torch-loop clocks have been generally replaced with torch-repeater loops. In these clocks, most of the delay comes from repeaters, with a single torch to provide oscillation. such clocks ca n’t be shorter than a 3-clock ( or the torch burns out ), but they can be extended about indefinitely ( subject to distance and material limits ). however, once the iteration reaches 9-16 repeaters ( delays of 36-64 ticks ), a TFF or clock multiplier can increase the period more stingily ( and compactly ) than adding huge numbers of repeaters. ) These examples are all ( R+1 ) -clocks where R is the total recidivist delay ( that is, they spend R+1 ticks OFF, then the lapp clock time ON. All have at least one potential remark that turns the clock OFF within half a bicycle ( after any current ON-phase passes the output ). ( Feeding an ON signal into the output besides stops the clock, but of course then the output is high gear. ) When the baron turns murder, the clock mechanically restarts .

Design A shows a basic loop clock. The repeaters must have a full delay of at least 2 ticks, or the torch burns out. Powering the block turns off the clock. As many repeaters as needed can be added, and the cringle can be expanded as needed with dust for cornering. The racing circuit as shown is flat, but large loops can be run onto multiple levels, to cut down on sprawl .

Design E is an extensile vertical clock. Its minimal size is 1×5×4, but it can be extended indefinitely, adding 2 repeaters ( up to 8 ticks check ) for each barricade of propagation. As shown, it has a minimal check of 5 ticks. ( This can be reduced to 3 or 4 by replacing repeaters with dust, or by using D rather. ) A lever or redstone signal behind the flashlight stops the clock with output OFF ( once any stream ON-phase passes the output ) .

Design D is a bantam erect clock, a compressed form of E, that can output a 3, 4, or 5-tick hertz. Earliest Known Publication: June 30, 2011 [ 1 ] The time period is the repeater ‘s delay plus 1, but the repeating firearm must be set to at least 2 ticks or the flashlight burns out. This circumference is formally 1×3×3, but is most normally built as a “ V ” on the grind, and can well be buried wholly .

  • A lever on, or redstone signal to, any of the four solid blocks can stop the clock. The torch is forced “off” while the dust is lit.
  • Output can be taken almost anywhere, with a few exceptions:
    • The blocks “crosswise” from the redstone dust (pistons work, but dust or a repeater is likely to jam the clock).
    • The block under the repeater (a repeater or piston next to it is out-of-phase, and dust does not light).
    • Output from the dust side is reverse phase.

Comparator clock

[

]

Comparators can be used to make fast clocks and slow pulsers .

subtraction clock

[

]

Subtraction 1-Clock

Subtraction 1-Clock

2×2×2 (8 block volume)
flat, silent
clock output: 1 tick on, 1 tick off
A subtraction 1-clock toggles on and off every tick. It uses a redstone comparator in subtraction mode, with the output feeding to the comparator’s side input.
When the comparator first receives full power, it outputs strength 15 to the block in front of it, which passes the same signal strength to the dust next to it. The signal strength then declines by 1 (to 14) as it moves to the dust next to the comparator. In the next tick, the comparator subtracts 14 from its 15 input to output only signal strength 1. This is enough to barely power the block and the dust next to the block, but isn’t strong enough to reach back to the dust next to the comparator, so on the next tick the comparator subtracts 0 from its input and the cycle starts again.

Inline Subtraction 1-Clock
2×3×2 (12 block volume) 2×3×2 ( 12 block volume )

Only the redstone dust next to the comparator actually toggles between on and off — the comparator, the block in front of it, and the dust next to the block toggles between signal strength 15 and 1. Add additional dust lines to these points to take output from them and allow the signal strength to decline to at least 14 and 0.
A subtraction clock doesn’t require full power for input — it works even with an input strength as small as 2.
Variations: Players can use any full container as the “input” if a power source would be inconvenient in that location (such as right next to the output).
Earliest Known Publication: February 9, 2013[2]
Subtraction N-Clock

Subtraction N-Clock

2×3×2 (12 block volume)
flat, silent
clock output: 2-5 ticks on, 2-5 ticks off
With the repeater set to a 1-tick delay, this is a 2-clock (2 ticks on, 2 ticks off). Increase the repeater delay to slow the clock down, or even add additional repeaters. If the input strength is higher than 1, the block behind the repeater can be replaced with redstone dust; if higher than 2, the block in front of the comparator can also be replaced with redstone dust. Output can be taken from anywhere as long as the dot of redstone dust can power the block behind the repeater.

Fader pulser

[

]

A fader pulser is useful for making little clocks with periods less than 15 seconds ( for longer periods, grasshopper clocks can be smaller ), but they are difficult to adjust to a accurate period. They use a fader racing circuit ( aka “ fader loop ” – a comparator closed circuit where the signal potency declines with every happen through the iteration because it travels through at least one duration of two or more redstone dust ), renewed by a redstone torch every fourth dimension it fades out .

Fader 9-Pulser

Fader 9-Pulser

1×4×4, 1-wide, silent
clock output: 1 tick on, 8 ticks off
When the input turns off, the redstone torch initially “charges” the fader loop at signal strength 15. There’s only one comparator in the loop so each cycle through the loop takes only 1 tick, and the signal strength declines by 2 each time through the loop, so the fader loop remains charged for 8 ticks. The redstone torch then turns on for only one tick because it short-circuits itself (the torch does not burn out because it’s held off most of the time by the fader circuit).
Fader 29-Pulser

Fader 29-Pulser

2×4×2, flat, silent
clock output: 2 ticks on, 27 ticks off
When the input turns off, the redstone torch initially “charges” the fader loop at signal strength 14 at the dust next to the block (the signal strength declined by 1 getting there from the torch). There are two comparators in the loop so each cycle takes 2 ticks, and the signal strength declines by 1 each time through the loop, so the fader loop remains charged for 28 ticks. One tick later, the redstone torch turns back on, re-powering the fader loop (it stays on for 2 ticks so it overlaps the fader loop’s on time by one tick).
Variations:

Fader 29-pulser vertical interpretation

  • Add more comparators to increase the clock’s period.
  • Add redstone between the first set of comparators to limit the on ticks to 2
  • Skip the redstone torch for a non-repeating version (pulse extender).
  • 1.16+ vertical version doesn’t work because of redstone changes

Alternating clock

[

]

Alternates between two unlike sign strengths every early check mark .

Can be used to compact circuits that require lockstep time .

Hopper clocks

[

]

A hopper clock ( a.k.a. “ hopper timekeeper ” ) uses the movement of items between at least two hoppers to create a clock signal. general aspects :

  • flat/tileable
  • noisy/silent
  • clock output: from 4 ticks on, 4 ticks off to hours and days or short impulses
  • clock period: from 8 ticks to hours and days

Dropper-Dropper clock

[

]

Dropper-Dropper Clock

7×4×2 (56 block volume)
clock period: 4 ticks/item (up to 230 seconds)
Earliest known publication: Apr 24, 2018[3]

simpleton design that does not require iron, because it uses no hoppers or pistons. however, it does require nether quartz glass. Pulsing output can be taken from the long scatter trails in the top-right and bottom-left corners, while stable output can be taken from 1-tile dusts at top-left and bottom-right. The repeaters at the crown and bottom are set to 3 ticks .

Despawn clock

[

]

A despawn clock uses item despawn timing to create a clock sign. Simply approaching a despawn clock can interfere with its time, because any actor might unintentionally pick up the despawning item .

Dropper Despawn Clock

Dropper Despawn Clock
Additional blocks are required on each side of the pressure plate. The dropper is filled with items. extra blocks are required on each side of the pressure home plate. The dropper is filled with items .

3×3×2 (18 block volume)
clock output: 5 minutes off, 3-7 ticks on
Start the clock by turning off the input. The torch turns on, the dropper drops an item on the pressure plate turning the torch off. After 5 minutes, the item despawns (disappear) and the pressure plate deactivates, allowing the torch to turn on, causing the dropper to eject another item onto the pressure plate.
If completely filled with items, the dropper must be re-filled every 48 hours, or continually supplied with items from a hopper pipe. Two chickens constrained above a hopper can keep a dropper despawn clock supplied with eggs indefinitely.
Variations: Longer clock periods can be achieved by chaining multiple despawn clocks together, so that each torch triggers the next dropper instead of its own. When chaining multiple despawn clocks, the dropper must be placed so that it is activated only by the previous torch and not the previous pressure plate.
A dispenser can also be used, instead of a dropper, but is slightly more resource-expensive (and not advised with use of eggs).
Summon Despawn Clock

Note: This circuit uses This circuit uses command blocks, which can not be obtained legitimately in Survival manner. This racing circuit is intended for waiter ops and venture map builds .

Summon Despawn Clock

1×2×2 (4 block volume)
clock output: up to 32 minutes off, 1.5 ticks on
The command block executes a command to summon an item onto the pressure plate. The exact command can vary, but looks something like this:
/summon Item ~1 ~ ~ {Age:X,Item:{id:"minecraft:stick",Count:1b}}
The command above summons an item entity (an item in the world, rather than in a player or container inventory), one block in the +x direction (west) from the command block, and specifies that the item is a stick and has an “age” of X.
Replace X with a value that determines how long the item should last before despawning: 6000 – 20 × (for example, 5940 for a 3-second despawn). Every game tick, this value increases by 1, and the item despawns when the value reaches 6,000. Normally, items start at 0 and last 5 minutes (6000 game ticks = 300 seconds = 5 minutes), but setting the item entity’s initial Age changes that.
When calculating X for a specific clock period, note that pressure plates stay active for a short period after the item despawns. A wooden pressure plate takes 10 ticks (1 second) to deactivate after the item despawns and a weighted pressure plate takes 5 ticks (0.5 seconds). This also limits how fast a summon despawn clock can be made to run.
X can be negative for clock periods greater than 5 minutes (for example, -6000 for a 10-minute despawn). The maximum time possible is a little over 32 minutes, with X = -32768 (-32768 = 27.3 minutes, plus another 5 minutes to get to +6000).
Start the clock by turning off the input.

Command block clock

[

]

Note: These circuits use These circuits use command blocks, which can not be obtained legitimately in Survival mode. These circuits are intended for server ops and adventure map builds. A setblock clock works by replacing a block of redstone or a redstone torch repeatedly with a command block activated by the obstruct of redstone it places. A /setblock command takes 0.5 ticks to place a block, so these clocks are capable of producing 20 0-tick pulse per moment. entirely redstone dust, note blocks, and other instruction blocks can activate that quickly – other mechanism components and repeaters powered by a setblock clock normally pulse lone 5 times per moment ( like a 1-clock ), while comparators may activate once and then stay on or not activate at all. To prevent the destroy blocks from dropping items use /gamerule doTileDrops false. To prevent the clock from spamming the chat use /gamerule commandBlockOutput false. To prevent the clock from spamming the waiter log practice /gamerule logAdminCommands false. Both of these clocks begin running a soon as they ‘re built. To turn them off, activate the command stop setting the parry of redstone from a secondary beginning. To turn them back on, remove the generator of secondary activation and replace the block of redstone .

Setblock Clock

Setblock Clock

1×1×2 (2 block volume)
1-wide
clock output: 0-tick pulse every 0.5 ticks.
The command block should have the following command: setblock ~ ~1 ~ minecraft:redstone_block 0 destroy.
Variations: The command block and block of redstone can be configured in any direction.
Silent Setblock Clock

S

R

Silent Setblock Clock

1×1×2 (4 block volume)
1-wide, silent
clock output: 0-tick pulse every 0.5 ticks.
Command block “R” should have the following command: setblock ~ ~-1 ~ redstone_block. Command block “S” should have the following command: setblock ~ ~1 ~ stone (or any other solid opaque block that doesn’t cause light updates when replacing the block of redstone).
Variations: The command blocks and block of redstone can be configured in any way that the block of redstone can power both command blocks simultaneously, but command block “S” executes before command block “R” (command blocks that are powered simultaneously activate from lowest coordinate to highest coordinate on each axis).

Fill Clock

A fill clock works just like either version of the setblock clock, except it uses the /fill command to setblock an entire volume with blocks of redstone. This allows the clock to activate or power many locations at once without lines of redstone dust requiring support blocks.
Command block “R” should have the following command: fill ~ ~-1 ~ ~4 ~-1 ~ redstone_block. Command block “S” should have the following command: fill ~ ~1 ~ ~4 ~1 ~ stone (or any other solid opaque block that doesn’t cause light updates when replacing the block of redstone). Adjust the commands for the number of blocks of redstone required and the direction they are oriented.
Positions “a” could be command blocks, note blocks, etc.

Piston clock

[

]

Pistons can be used to create clocks with a modifiable pulsate delay without the use of pulse generators. In Java Edition pistons can be clocked in a fashion that leaves the arm extended only for the time required to push an adjacent block. however, note that if awkward pistons are regularly used this way ( that is, as a 1-clock ), they can occasionally “ drop ” ( fail to retract ) their stop, which normally stops the clock. ( specifically, if the apparatus allows for a pulse less than 1 check long, that causes a awkward piston drop its freeze. This can be useful, notably for toggles. ) piston clocks in general can be easily turned off or on by a “ toggle ” remark T .

Minimal Piston Clock ( A )

[

]

Design A requires only a gluey piston and redstone wire, and is controllable. It runs equally retentive as the toggle pipeline ( its exponent beginning ) is on, and turns off when the toggle line is off. Repeaters can be added to increase its stay. If the repeater is replaced with telegram, it can be used as a 1-tick clock, but it is prone to “ dropping ” its engine block .

minimal Dual-Piston Clock ( B )

[

]

Design B shows how to counter block dropping with an optional, non-sticky, piston. The not awkward piston ( the bed one ) is needed for the 1 click clock as a self repair mechanism. It prevents detaching of the moving block from the sticky piston. If using it only for a 1-tick bicycle, the recidivist ( under the extended piston ) can be replaced with redstone wire. The toggle line stops the clock on a high signal .

double Block Piston Clock ( C )

[

]

Design C requires two sticky pistons, and can be easily stopped by just setting one side of the redstone high. The repeaters can be indefinitely extended to make a long delay clock .

compact Sticky Piston Clock ( D )

[

]

Design D needs merely one gluey piston, but at the repeater must be set to 2 or more ticks. If it is set to one check, the blowtorch burns out. The output signal can be taken from any separate of the circuit. This design can besides be controlled ; a high stimulation on the toggle line stops the clock .

Advanced 1-tick Piston Clock ( F )

[

]

Design F is an unusual, stable, 1-tick piston clock. Unlike most repeater-based 1-clocks, its sign is flying adequate to make a awkward piston reliably toggle its parry, dropping and picking it up on alternate pulses. For the clock to work, the block the piston moves must be placed final. The piston extends and retracts cursorily. The output wire appears to stay off, because it ‘s changing state faster than the bet on visually updates. however, attaching a redstone lamp, dispenser, dropper, piston, etc. to the output shows that it is working. The clock can be turned off by a redstone bespeak ( e.g. the lever shown on the blockage below it ) to the piston. This clock is 2 blocks high, 3 wide, and 5 long. There is a firm freeze under the piston. The redstone torch between the recidivist and the output signal line is at anchor level .

dim-witted 3-gametick Piston Clock ( G )

[

]

Design G is the simplest design and can be used to create rapid clocks. however, it is not controllable, so the only way to stop such a circuit, without adding extra parts, is to break one part ( one redstone wire is recommended ). Place a jam of redstone on a sticky piston, then lay down redstone so that the obstruct powers the piston. then, once the piston is powered and moves the blockage, the redstone current stops, pulling the obstruct back to the original position, which causes the forget to might the wire again, and so on. This clock creates a 0-tick pulse every 3-gameticks .

Self-Powered Piston Clock ( H )

[

]

Design H is the elementary and the lone one used vertically. To make this design, place a awkward piston facing up with a redstone wire next to it on one edge. next to the redstone electrify but however 1 stop off from the piston, place a solid jam and place redstone telegram on top of it. then, future to that block, but calm 1 block away from the piston, position obsidian two blocks up with a redstone cable on top of it. Above the muggy piston place a slime block. last, on top of that, place a redstone freeze. The clock activates immediately. It works on the principle of quasi-connectivity, and the wire directly next to the piston is used to update it. Players can besides add on to this plan and make it toggleable. To do this simply make a sticky piston push a solid jam blocking the path from the redstone block to the piston. Because solid blocks stop redstone from connecting with a engine block diagonally, this stops the piston from powering on again and starting the clock again. Players can connect a lever to finish this addition .

0 Tick Piston Clocks

[

]

0-tick clocks make use of 0-tick pulses and 0-tick chain to create 0-tick pulses on a even footing .

1-output 3-gt clock

[

]

Every 3 gameticks, the redstone block is 0-ticked to left and then 0-ticked back, creating a 0-tick pulsation. The clock can be toggled by cutting the redstone line on the right

2-output 3-gt clock

[

]

This redstone clock create two 0-tick pulses every 3 gameticks. The 0-tick pulses are timed with the right obstruct event delay to allow the pulses to faithfully chain two 0-tick pulses. When the recidivist is powered, the back muggy piston starts extending. This un-cuts a redstone electrify below the blocking, causing the front gluey piston to be powered and extend, causing the back piston to 0-tick tick block. This then causes the exceed pulley to get 0-ticked back, cutting the bottom wire again, and outputing a 0-tick pulse on the leave. This causes the front piston to get 0-ticked, which then gets 0-ticked back, creating the moment 0-tick output on the right field .

1-gt clock

[

]

This clock makes habit of three modules that output a sign every 3 gameticks, offset from each early by 0 gameticks, 2 gameticks, and 4 gameticks respectively. This outputs a pulse every gameticks, or 20 times a second .

Minecart clock

[

]

Minecart clocks are elementary, easily to build and modify, but are slightly treacherous. A minecart clock is made by creating a small track rails with one or more power and detector rails, arranged then that a minecart can run constantly either around the track ( A ), or back and away from end to end ( B, C ). ( These need not be sloped—properly placed powered rails lets a minecart “ bounce ” off solid blocks — but the player get some extra time as the handcart slows down. ) The redstone torch can besides be placed in the center of the rails, making it more compact. A larger vertical track ( blueprint C ) is claimed to produce an exceptionally stable clock. note that the minecart never quite hits the top of the track. When running an empty minecart on the loop or back-and-forth, the cart generates redstone signals as it passes over the detector rail ( s ). Minecart clocks can be extended or shortened easily by adding and removing cut, to adjust the delay between signals. On the pass side, they are well disrupted by wandering players or gang, and a long clock can take a fair snatch of space. besides, the exact period is by and large not apparent from the design. The need for gold in the booster rails can besides be a trouble for some players .

observer clocks

[

]

Two observers watching each other makes for a compendious rapid clock. creating a 1-tick clock. One perceiver with redstone to let it watch itself can besides be used. Wrap the redstone from the observing point over the top and around one english of the perceiver to the input. Break and replace the redstone being observed. You can add repeaters for longer periods. To switch the clock on of murder, a lever can force the circuit high as usual, or a piston can be used to move one of the observers .

Alternating piston clock. In one check mark, the other perceiver senses that there is a red pit signal in the foremost one and output its own redstone signal. The first observer then senses this the following check, and so on .

Long-period clocks

[

Creating long repeater loops can be expensive. however, there are respective sorts of clocks that are naturally quite long, or can well be made so, and some are described above :

  • Devices can send item entities through the world: Items flowing on a stream, falling through cobwebs, or just waiting to despawn (that’s a 5-minute timer provided by the game). Droppers or dispensers, and hoppers with comparators, can be quite useful here.
    • Additional stages added to the multiplicative hopper-dropper clock each multiplies the previous clock period by up to 1,152, quickly increasing the clock period beyond any reasonable use.
    • A simple despawn clock is shown above. These do have a couple of liabilities:
      • If the pressure plates are not fully enclosed, the trigger item may fall to one side, stopping the clock.
      • The droppers eventually run out of items. A droppers full of (e.g.) seeds serve for 48 hours, that is 2 days of real time. If this is insufficient, hoppers and chests can be added to refill the dropper (12 days per chest’s worth). Alternately, a pair of chickens can provide enough eggs to keep the clock going indefinitely. A small full-auto melon or pumpkin farm can also serve to fill the hoppers.
  • Boats and minecarts can be used with pressure plates or tripwires.
  • Pseudoclocks can even be based on plant growth. For these, timing isn’t exact, but they can still be useful for getting occasional signals over long periods.
  • “Factorial stacking” of clocks: Precise clocks (that is, repeater or repeater-torch loops) with different periods may be connected to an AND gate in order to generate larger periods with much less expense. One way to make a 60-second (600 ticks) would be to use 150 repeaters set on 4-ticks of delay, or players could connect two clocks with the periods of 24 and 25 ticks (that’s 13 repeaters) to an AND gate. Note that if the input clocks’ on state is longer than 1 tick, they must filter them with an Edge Detector or Long Pulse Detector, to prevent overlapping on imperfect syncs. The disadvantages here are:
    • The circuitry can be fairly finicky, and players may need a circuit just to start all the clocks simultaneously.
    • The lengths of the sub-clocks need to be chosen to avoid common factors in their periods. This list of the first few prime numbers may be useful: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103. Any one of the clocks can be an integer power of a different prime, and they do not share factors or they occasionally “beat” together, causing an extra or missed pulse.
    • A cycle of 1 Minecraft day (24000 game ticks, but 12000 redstone ticks) can be produced by stacking clocks of periods 125, 32, and 3. A multiplier (as described below) may be helpful for the longest of these.
  • Then there’s the obvious: the daylight detector acts as a clock with a period of one in-game day. The duty cycle can be adjusted by using comparators at different threshold values. Keep in mind that weather may interfere with this, and of course the phase is fixed. The daylight sensor does offer a unique feature: Since it responds to the actual progress of the game day, it does not lose time if its chunk is unloaded. Naturally if its chunk is not loaded, it can’t actually activate any circuitry, but when a player comes by later, the clock remains in sync with the daily cycle. By comparison, suppose that (say) an MHDC with TFFs extending it to 20 minutes is started at dawn, but the chunk is then unloaded. When the player comes back to reload the chunk (say, at dusk), the clock continues counting its 20 minutes from wherever it left off.

There are besides a pair of extension techniques that apply to any clock any, including irregular pseudoclocks :

  • A T flip-flop can be used to double the period of any clock. This also converts the pulse to have the same length ON and OFF, if it didn’t before. (Pseudoclocks are not completely regularized, but they get smoothed out.)
  • Latched repeaters allow production of a general clock multiplier, detailed below. This can be used to multiply the period of any clock, and they can be used in series.

Clock multiplier

[

]

This nearly-flat circuit ( besides known as a ring counterpunch ) takes a clock input of period P and any pulsation length, and outputs as a clock of period N×P, where N is the act of latches used ; the output signal is on for a pulsate length of P, and off for the remaining (N-1)×P. N is limited to 12 or so by redstone bespeak attenuation ; however, the design can just be repeated to multiply the period again, e.g. a 21-multiplier can be made by chaining a 7-multiplier and a 3-multiplier. This can be continued indefinitely, and unlike factorial stack there is no restriction on the multipliers .

The build is slightly catchy : The multiplier loop is in fact a torchless repeater-loop clock. This needs to be started individually, before the latches are engaged. The easiest way to start it is probably to add a temp “ startup tour ” starting 4 blocks from the scatter part of the loop : place a world power reservoir, then dust and a block for it to power. last place a redstone flashlight on the block, positioned to world power the redstone loop. The blowtorch flashes on for one tick before “ realizing ” it is powered, and this starts the cringle as a clock, which cycles until the latches are powered. This inauguration rig can then be removed. The latches are driven by an border detector, which takes a rising boundary and produces an OFF pulse ; the pulsate length must match the delays of the latch repeaters, so that the multiplier ‘s pulsation advances one repeating firearm per border. The delay/pulse length must besides be no longer than the remark clock, so it ‘s credibly best to keep them both at 1. note that the delays of the latch repeaters are not actually part of the output period ; the latches count off input signal edges. The racing circuit ‘s end product is ON while the last repeater is unhorse and lighting the dust closed circuit. This tour need not be fed with a even clock. With any varying input signal, it counts N rising edges and output HIGH between the ( N-1 ) thorium and Nth rising border. Variations:

  • A T flip-flop can be used to “normalize” the pulse to half on/half-off, while doubling the output period. Design L5 from that page is suitable and compact.
  • By separating the latched repeaters with redstone dust (to read their signals individually), this circuit could be generalized into a “state cycler”, which can activate a series of other circuits or devices in order, as triggered by input pulses.
  • The return line can be run underneath the clock, making the build higher but narrower, or the entire repeater-latch loop can be extended to run backward on a lower level, similar to Torch-Repeater Clock design E. If used as a state cycler, this also makes the dust between the steps more accessible.

Efficiency: An effective approach to making long-period clocks is to start with a repeater cringle of 9 to 16 repeaters ( up to 64 ticks ), then add multiplier banks with N of 7, 5, and 3 ( bigger is more efficient ). Doublings should be done with T flipflops, as 2 of those are cheaper and possibly shorter than a 4-multiplier. A copulate of notes :

  • Using two 7-multipliers (×49) is slightly more expensive, but shorter, than getting ×50 with 5×5×2, or getting ×48 with 3×4×4 or 6×8;.
  • An 8-multiplier is slightly more expensive, but shorter, than separate 2- and 4-multipliers. However, two of them are both longer and more expensive than three 4-multipliers.

Redstone Repeaters with Feedback

[

By using a ring of redstone repeaters tapped at specific intervals and an OR gate set in a feedback loop highly long durations can be created. Durations of minutes, hours, even days can be created using a minimal sum of parts. Clock motorbike time = 0.4 × ( 2n – 1 ) seconds. Hence each time the player add a single redstone repeater, they can efficaciously double the cycle time. The like racing circuit can be used to create long duration clocks and delays of any duration in 0.4s increments. Super Delay on YouTube [ 1 ] copy of working minecraft save game [ 2 ] Below is an model of a free running 10 element clock that takes 409.2 seconds ( 6.82 minutes ) to hertz. It outputs from the XOR Gate a unique stream of 0 ‘s and 1 ‘s that repeats every 409.2 seconds. 10 element free running.png To turn it into a clock all we need to do is add a 10-Input decoder that looks for one of those unique sequences. A NAND gate goes depleted when all redstone repeaters are outputting gamey. 10 element free running with NAND gate.png By adding a RS interchange, we can reset our clock. 10 element free running with NAND gate, on off.png here is a version where the decoder resets the clock at the 3 minute mark. 3 minute delay.png LFR 10 3min.jpg In electronics this device is normally known as a “ linear Feedback Shift Register ” ( LFSR ), players can make them count up, count down, create psudo-random binary sequences for testing logic circuits. In TCP/IP a 32-bit ‘Linear Feedback Shift Register ‘ is used to perform data integrity checks ie CRC-32. LFSR ‘s besides create the codes for CDMA phones and GPS ( Global Positioning System ). note that the XOR gate takes it inputs ( Taps ) from redstone repeating firearm 7 and 10. For simplicity sake, these have been listed 2 tap LFSR sequences. In Minecraft, one could make a 1-many delay line social organization to create more complicated clocks.
