Some of the designs are more than two blocks high which is represented here by the layers being frames in an animated gif or labeled side by side. A full legend is on the Redstone schematics page.
Mechanisms are complex systems of blocks used to perform certain tasks, such as opening a door from afar or revealing a hidden staircase. These systems are built from simple components and normally involve some kind of user input, such as breaking a torch, which generates some kind of result, like a door being revealed. Mechanisms can range from simple switches that open and close doors from a safe distance, to complex devices such as combination locks that prevent intruders from entering your fort.
This page is a work in progress, so feel free to add your own components and mechanisms as you build and the game develops. Pictures are encouraged, but not required.

These are the basic, modular parts which can be combined to form any complex mechanism. Please note that individual items in the game are not considered components. Also, not all of these components have to be used when making a mechanism.
- Water Channel: A channel in which water can flow. Water is commonly used to break torches, causing things to fall, or washing away crops.
- Tube: A long three by three structure that can be used for launching TNT.
- Piston Switch: Block 1 above ground level with redstone on top, with a piston that moves across to stop circuit. Used so pressing a button or lever will stop another circuit.
Mechanisms are useful devices made from the combination of components. Here are some examples:
- Basic Mining explosive device
- Advanced MED
Build a circuit that involves a piston being shut off by a button, then build an obsidian tube with a hole in the middle to store carts. Be sure not to make the tube too tall, or else the minecarts will blow at the bottom. Then make a single rail at the top of the tube, surrounded by walls, so you can push the cart in. When it's at the bottom, get down to the button and watch it ride the rails. This also works as a minecart storage unit.
- Table trap
Make a pressure plate-fence table and put TNT underneath it. Dropping food on the table will activate it.
- Minecart Storage System
This is a a storage system that allows a user to call a minecart and return them.

- Efficient Mob Farm
This mob farm, using tripwire and pistons, yields 5364 drops per hour and enough gunpowder to make over a stack of TNT In 20 minutes.

- Visitor Counter
A piston, redstone and pressure plate door that counts which way someone went through a door.

- X-Ray Device
This device uses glowstone and pistons. This can also be done with redstone blocks and TNT. However, if you use redstone and TNT, you may accidentally detonate the TNT. Also, note that some servers ban the use of X-Ray devices. Note: Redstone Blocks and TNT also have this effect. (Just be sure to not detonate the TNT with the redstone.)

- Potion Dispenser
For this device, you can stand on a pressure plate and make splash potions shoot out of a dispenser. See the following steps for how to make it:
- First, make a dispenser dispense splash potions. Then, place a dispenser one block over the floor level.
- Place a fence on the side the dispenser will shoot the potion out from. Finally, put pressure plates on top of the fence.
See the following video for a better demonstration:

EmbedVideo received the bad id "ziGhiF2TvTQ&" for the service "youtube".
- Hidden Floor Staircase
By breaking a torch, you will reveal a hidden staircase.
- Make an inverted sand or gravel staircase in the floor of a room (one block wide), supported by torches.
- Make a water channel or water channels adjacent to the torches so that when they are filled, the torches break and the stairs will fall. (IMPORTANT: make sure that that the sand or gravel will cover the water hole after it falls to avoid flooding)
- Make a sand switch which opens a reservoir allowing water to flow down a short channel to a pit. The pit allows the water to drop beneath the floor and run to the torches holding the staircase.
Look at the following video:
|YouTube Video (https://www.youtube.com/watch?v=OYPe1limPKQ view on YouTube)|
- Hidden Wall Staircase
This design features a hidden staircase in the wall, revealed by triggering a redstone signal in some way, such as pulling a lever or pressing a button. There are many ways of making this. look at the following 2 videos for some examples:
|YouTube Video (https://www.youtube.com/watch?v=Fd1XmabZqzc view on YouTube)|

- Redstone Lamp Floor
A redstone wired sequence of Redstone Lamps to mimic the lighting of a working floor. Video below.
|YouTube Video (https://www.youtube.com/watch?v=4x-spTuaxqE view on YouTube)|
- Rapid Pit Bomber
To make this design, make a dispenser attached to a redstone clock mechanism and hopper to feed it items. In front of the dispenser, place a powered rail on a block of redstone and fill a chest above the hopper with Minecart with TNT. This will rapidly dispense those rail-riding explosive atrocities onto a powered rail and into a massive crater of their own. It can even tunnel down to bedrock given enough carts.
More advanced mechanisms
- Programmable Item store / Cash Register system
This is a system that will let you program what items you want to sell, how many you will give, what you want to be paid and how many of those to be paid. It will lock when its empty. This is a very compact 3W x 7L x 5H system and tile-able.
|YouTube Video (https://www.youtube.com/watch?v=cdj1ot1NJZM view on YouTube)|
- Combination Lock
A door which is opened by using levers to input a certain combination. The levers are wired to an "AND" gate, with hidden redstone circuitry to open the metal door.

- Cobblestone Farm
A farm which uses a clock circuit, water, lava and pistons to farm cobblestone.
B= Any solid block R= Redstone W= Water L= Lava T= Redstone Torch E= Redstone Repeater P= Piston
BBBBBB BW WB PPPP EEEE
BBBB BLLLLB BBBB
Pick a good, working redstone clock to use, and then wire it to the redstone repeaters. The Clock Circuit should blink on and off, and eventually you will have 44 blocks of stone. (11 for each Piston)
- Item Activated Door
A door that only opens when an item is dropped into a pit of water.
- Make three-deep a pit near an iron door. Build a level channel away from the base of the pit.
- Place a wood pressure plate in the channel no more than 8 blocks from the base of the pit. Wire the plate to the door (not through the channel). You will have to run the wire back up to the surface, or very nearly so, but it can be concealed under well-placed walls.
- Cover the channel and place a block of water at the top of the pit, allowing Water to flow down the channel. Any item thrown in the pit should flow down to the plate and cause the wire to activate, thus opening the door.
- Flashing Indicator Light
A blinking red torch activated when a pressure plate is stepped on. Can be used to tell if mobs are sneaking through your caves.
- Make a pressure plate wired to the input of a red torch. Wire the output of the first torch to the input of a new red torch. Run the output of the new torch to its own input, creating a blinking loop.
- Wire the output of the new torch to the input of any other torch to carry the blinking effect.
See the following example:
The loop on the right will flicker on and off when the plate is stepped on. Warning: This burns out quickly if a single torch is used, so take this fact in mind.You can also use a redstone repeater to slow down the process on the loop back to the torch so it does not burn out
Multiple torches hooked up:
Sound could be added to make an alarm by wiring note blocks to the flashing torches.
- Block Destruction as a Trigger
It is possible for an electronic output to be generated as a result of a block being destroyed. To achieve this, place a Redstone Torch on the side of a block facing away from you. Next, set up an inverter between the block and your mechanism. When the block is destroyed, the torch will fall, the lack of input will be inverted, and the mechanism will activate. This can be used to make traps, as shown in this video:
|YouTube Video (https://www.youtube.com/watch?v=DajXT6sqfcI view on YouTube)|
- Redstone Tower
The bottom torch powers the block above it, powering it and all redstone torches attached to the block. Each level (block with torch on top) acts like its own repeater. This also can go upward until the map ends while still producing power. If you want to dispose of this quickly or are making experiments just use Gravel or Sand for the block type.
The glass allows the redstone current to pass through while the other moveable blocks do not. This can be used to operate doors, bridges, etc. The best part is you can use multiple Buttons and make doors that open from both sides using the same circuit. The tutorial can be viewed here:
|YouTube Video (https://www.youtube.com/watch?v=IIYL-PCVwgE view on YouTube)|
. There are also images with pistons.
- 2 Wire Control
With a lot of repeaters and AND-gates it is possible to control multiple outputs with only 2 wires. It can be very tricky to get the timing right. You need a pulse generators in both wires to get a pulse with a defined length and in most cases the output pulse needs to be made longer. As shown in this video you have a top wire and a bottom wire with repeater. On one side you have repeater between the Buttons on the top wire and none (or as needed) in the bottom wire. At the other side none (or as needed) on the top wire and matching repeater (to the others top side) on the bottom one. between which you place AND-gates (matching the Buttons). The Idea is that the signals only meet at one AND gate at the same time. Video tutorial:
|YouTube Video (https://www.youtube.com/watch?v=NW75acQqH7Q view on YouTube)|
|YouTube Video (https://www.youtube.com/watch?v=ERBIU8yDza8 view on YouTube)|
- Redstone "Clock"
When working redstone, when activating the wire, it only does its job once. Sometimes this is good, like with doors, but sometimes this isn't good, like with note blocks. A simple way to repeat the current is the "clock" as follows: Dig four 1 block holes in the shape of a cross without the center. Place redstone torches in the holes. Place blocks on top of the red stone torches. This is not part of the process, but is need when actually powering something. Place one block of redstone in the center of the cross. This will cause the redstone to restart rapidly, which can be useful when working with note blocks.
- Two-Switch Door
Opening and closing a door with two levers is normally impossible; with one lever on, the door is always open. With the use of a redstone XOR gate though, that isn't the case. A door can now be opened on one side, then closed from the other (think of a light with two light switches). Refer to the videos for more.

These "Jeb doors" can also be referred to as flush-inset Piston doors. Here is an example of one of these, with a redstone torch key system added on. Once broken down, it's not extremely difficult to build.

This design is even more compact than the previous one; however, it blocks sight. It's great for building elevators in shafts. Note: As of 1.2.5 update you need to set the pistons to 3 instead of 2. The first is still to be set on 4.
Two-way elevators can be built, but they are slower and much more complex than the previous ones. They also require a lot more space and resources. The below is a slightly modified design by CxoLethe.
|YouTube Video (https://www.youtube.com/watch?v=cix161oQWGA view on YouTube)|
The two-way elevator can be built the following way:
The engine shown below of this text uses wool between the pistons and the fence gates/trapdoors. However, instead of wool any other block can be put there, as long as pistons can push it.
The schematics for the wiring assuming that you know how to make a 1 tick long impulse. A 1 tick long impulse can be obtained using a pulse limiter. In both of the schematics, empty squares represent air blocks, and repeaters all have the minimum delay possible.
A screenshot of an implementation of this design:
Also, see this video for a larger two-way elevator:
|YouTube Video (https://www.youtube.com/watch?v=zLWv0yxh7ic view on YouTube)|
A launchpad is similar in design to a TNT cannon, but instead of launching horizontally, it launches vertically either straight up or at an angle, depending on the design. There are many ways to create them, but some methods are more efficient than others. For instance, a simple design would be the cross pattern, as shown below.
This is what it would look like from above:
S S BWRWB SWWRWWS RRPRR SWWRWWS BWRWB S S
To load it, place TNT on the flowing water blocks.
The above design can easily be expanded in size and improved, but it is one of the easiest designs so far. Another simple design, yet much more powerful, is here:
|YouTube Video (https://www.youtube.com/watch?v=8b7V4QS9Vg4 view on YouTube)|
Another powerful design, using dispensers to place the tnt is built as following:
The dark blocks on the last two on the right represent dispensers, facing the center. If you want this to be reusable, place a water source between them. A pressure plate delay is enough for each dispenser to shoot twice. An interactive version is here: 
A redstone battery is a device to constantly output redstone power without requiring a power source.
It's a contraption that, when activated, cannot be deactivated unless broken.
The simplest one is as following:
If you want to make a battery with a delay on portions of it, use a clock, but don't deactivate the signal.
This will still work as a battery, but half of it will have a small delay upon starting.
Piston-Redstone Block Engine Prototype
This design will make an automatic piston.
..r# ddsd d.pd dddd
.=Nothing, r=Redstone block, d=Redstone dust, s=Sticky piston, p=Pressure plate, #=Removable redstone dust
The pressure plate is to reset and to single-step it.
To shut it off, remove the removable redstone dust.
Piston gates, or portcullises, consist of a large set of fences that will be pushed up when the gate is opened, and down when closed.
Here is a very small and resource efficient build with a fluid opening motion:

A device that rapidly produces smoke. To build dig a 1x1 hole in the ground and place a ring of cobblestone 1 block above the surface, with the hole of the ring above the hole in the ground. Now place lava in the middle of the cobble ring, then place water next to the lava on the surface. Now put two repeaters set to 1 tick next to the water. Place 2 pieces of redstone infront of the repeaters next to the lava, then hook up a repeater clock and connect it to the redstone. It should look like this.
And you now have a rapid smoker!
Building Protection Sensors
The following are circuits designed to prevent changes to the structures without the use of Operator right.
There are multiple ways of protecting a wall. Firstly being the easiest which is to protect the bottom of a two high wall, players going through it would break both and ergo the bottom as well, this trips the circuit giving you a positive redstone circuit.
(X) stands for a floor / wall of any material that redstone can be placed on. (-) stands for redstone. Below is a 2D cut of a piece of the wall. The principle of it is that when the lower block is broken the circuit is then connected.
XXXX XXXX X X-- X-XX XXXX
Iron doors are good and strong; however, their ability to be broken is their major problem. One of the best ways of avoiding this is as follows.
To avoid the problem with a torch being placed to open the door easily, place an iron door in a position so that its ON state blocks the entrance, then by powering it from beneath, you can stop it from being opened.
To then avoid someone breaking the door, place a block of Water above it, then another torch a block away behind the door. When the door is broken, the Water falls down and breaks the torch, giving you a negative which can be used.
X = Ground. w stands for Water. I stands for torch. - stands for wire
XwXXXXX | | I--- XXXXXXX
However, due to the slowness of Lava (and Water), it may be beneficial to make a Sand or Gravel block drop, dislodging a piece of wiring or a torch, or having another iron door behind the trapped door that will slow them further. The possibilities are endless.

These systems can be useful in many complicated mechanisms, or simply for aesthetic value.
(These are useless in 1.5 because of the addition of the Daylight Sensor, which performs the same function in a one block space) With the improvement of villager AI in the most recent snapshots (post-1.1), compact, sensitive, and resettable day/night detectors can be created by utilizing their differing day/night pathfinding systems. (Note: This does not work in minecraft 1.2.4, due to the fixing of the bug that caused NPCs to be confused on not-full blocks)
This is a video showing how the smallest version is built and used.

|Compact block swapper (https://www.youtube.com/watch?v=VZ1tL2MGPUE view on YouTube)|
A vertical switch can be made using pistons and sand blocks. The uses are limited by the tower of sand placed in front of the piston. When the piston is activated, the sand gets pushed into a hole. At the bottom of the hole, place a powered repeater with the output facing where the sand will drop. By adding a second repeater two blocks in line from the first one, you will have a broken circuit which is activated by the sand block when it lands.
Additional pistons can be used to push the sand away at the bottom to reset the mechanism. By adding a Torch where the Sand falls when the mechanism is reset, you do not need to remove the blocks manually. There is still no way to generate Sand dynamically, so you are dependent on the tower of sand at the top. This tower can be as high as you want, up to the build ceiling. The number of sand blocks available could be increased by having a second sand tower supplied by another piston when the first tower is empty.

Redstoning with Command Blocks and Scoreboards
Here is a tutorial on how to use scoreboards and testfor commands to run redstone devices.
|YouTube Video (https://www.youtube.com/watch?v=YGdGqq5BCac view on YouTube)|
Pressure Plate Trap
- Make a 20 x 20 x 4 hole.
- Put a layer of Water on the bottom.
- Put TNT on top of the Water, except for one pathway which you can get across. You can make the pathway with any block unaffected by gravity.
- Put Pressure Plates on top of them.
This is an updated, better, expandable bank system. This video also has an older bank system showing how to make one without using powered rails (broken link).
|YouTube Video (https://www.youtube.com/watch?v=6uaGLHEySx0 view on YouTube)|
This is a simple bank system using powered rails, which should be helpful for Minecrafters less experienced with redstone.

Guaranteed Death Landmine
This form of landmine causes mobs to fall through a wide Sand pit being supported by TNT. the mobs will then fall into the pit and will be killed by the TNT. NOTE: This is NOT guaranteed to kill spiders, as they can climb out of the pit. Simultaneously detonated TNT can kill a full-health player in diamond armor.
First, dig a 3x3x3 hole in the ground.Put a layer of torches on the bottom, then a layer of TNT, then a layer of either sand or Gravel. Now, put Pressure Plates on top of the pit.To confuse players, put Pressure Plates around a large area.It should look like this:
5=Obsidian(Optional,to keep players from breaking the wall to get out.)
444 63336 52225 51115
NOTE: This is better to use on a beach or in a desert, because it is full of Sand
High speed item transportation & making items travel upwards
Since pistons came out, upwards item transportation became possible, and combining this with ice makes a high-speed item transportation machine. Ice under Water streams makes the items go a lot faster, so if you are living in a tundra biome, you get a big speed boost. If you aren't living in a tundra biome, it is still possible for you to make the machine (using Silk Touch or without the ice).

Detecting Redstone Placement
The new silent BUD switch design updates not only when there is an update going on adjacent to it, but also updates when there is redstone wire placed 1 block away from the BUD switch.

Boat RS-NOR Latch
It is possible to make a boat-based RS-NOR latch and save up 4 redstone. Instead of the 6 redstone the old design uses, this design uses 2 pistons, therefore 2 redstone. Has a few disadvantages as well as advantages.

Race Finish Line
This Requires 1.4.1 of Minecraft. The new Redstone repeater latch can be used to create a "finish line" mechanism, to determine the winner of a race. At the end of the course, put a pressure plate for each lane. From there, make a wire for each lane, leading to a piston or lamp which will indicate the winner. Run a latch from each wire to the others. You may want to suspend blocks over the beginning of the wires, so your racers don't run over the mechanism. Extending this to more than two racers will be somewhat more complex, and probably require another level of circuitry.
!=switch @=redstone <,>,^,=repeater (<=Left) (>=Right) (^=up),%=piston
% % @ @ ^<@ @ @ @>^ @ @ ! !
One-Way Redstone Pulse
This requires 1.3 or later. Since now a piston takes about 1 tick to extend, you can make a tiny monostable circuit that is activated by a pressure plate. Then you build a sticky piston with a block attached one block away from the monostable circuit,in which the sticky piston is connected to another pressure plate, one block away from the other.Then you connect the blocks on the bottom layers with repeaters. The output is the block that is pushed by the sticky piston. In Diagram it looks like this (3x4x3):
@ = Redstone % = Any transmittable block ^ = Redstone repeater (direction using the arrow) * = Air # = Pressure plate ! = Sticky Piston Top Middle Bottom #*** %*** @!%* **** %*** **^* #*** %*** @>%*
To do this, you will need:
A diagram is shown to do this.
8= Redstone Repeater o= Redstone dust B= Block of Redstone x= Redstone Torch
o o 8 o 8 o 8 o o o o 8 8 o o 8 8 o o 8 8 o o o o 8 o 8 o 8 o 8 o 8 o x B
Note that you can use any amount of redstone repeaters and dust, and you can place the block and the torch anywhere. But, for this to work, you need to break the torch quickly, since when the current went back to the first repeater, it will stop transmitting power. Also, all repeaters should be on the highest delay.
High speed elevator
Bear in mind that this design is broken as of Minecraft 1.3
If you use a sticky piston to push a stair towards you and you have no where to go,you will go up the stair at a very fast speed. So you can use this as an elevator. First,Build two high walls(keep one meter in the middle) to keep you from falling out of the elevator.Like this: a=Air g=wall
gggggg aaaaaa gggggg
Next,put sticky pistons on every floor like this:
gggggg saaaas gggggg
After that,put stairs like this:
gggggg staats gggggg
When you have done this,put stones and redstone above the stone around the elevator:
l=leveler o=stone r=redstone
orrrrrrr lggggggr rstaatsr rgggggg rrrrrrro
r rgggggg rstaatsr ggggggr r
Until every piston will be charged if the redstone is charged. Note:the leveler on layer 1 is connected with the red stone line on the other side. Finally,dig a door on the 1st and 2nd layer and put a piston on the edge of the top of the elevator connected with redstone.
Self-destruct mechanisms are useful when destroying critical buildings or creating secret areas.
- Lay TNT under critical areas of your base, about two blocks deep. This will prevent torches and other redstone contraptions from detonating your system early. Then, lay TNT to the surface in a 1x1 area and add a lever or button above it to complete the basic self-destruct system.
- In creative mode, one could use dispensers filled with enderman spawn eggs wired to a 5-clock Redstone circuit to release Endermen into your house, slowly assuring a semi-complete destruction of your base provided that it is made from blocks that Enderman can manipulate.
- Remote dispensers could be wired to release fire charges upon your Wood structures.
- Pistons could be placed to release the floor below sand walls to quickly remove the walls of a structure.
- A dispenser with a lava bucket could be used to flood your base with lava.
- Connect a mob farm to your base, and open it up. The mobs will cover your house. Creepers will detonate whenever anyone unwanted comes by, and the other mobs will fight and probably kill any intruders.

Flashing Redstone Lamps is an easy to follow redstone mechanism that can be created by new players to experienced redstone masters. This guide will make it even easier for the player.
- Step 1
- The Materials
Like the majority of redstone mechanisms, it is recommended to build this one in Creative to avoid errors and to save time. The only materials needed to achieve this is
- Redstone torch
- Powered rail
- Detector rail
- Redstone lamp
- Any type of blocks excluding those that may interfere with the redstone. You may use one for decoration, and the other for placing redstone.
- Step 2
- The road
Build the road to your desired size and shape. Place detector rails parallel to the location you want the redstone lamps to be. Keep in mind to maintain the minecarts to have a constant speed by using powered rails, but be sure you are placing the redstone torches to a place where it does not interfere with the redstone.
- Step 3
- A Redstone
Connect the Detector Rails to redstone, and connect that to redstone torches which you will put on top of a block that you may place inside or outside of the tracks. Be sure they do not interfere with each other, or the redstone torches that are connected to your powered rails, as they may not achieve your desired effect. After this step has been done, place another block with a redstone torch on top. Place a final block with redstone placed in it.
- Step 4
After this, you will place your desired Redstone Lamps in their place, if you are connecting only one per redstone, place it next to it, either horizontally or diagonally to it. If you are connecting more than one, connect redstone to this pattern, R B R B, R representing the redstone lamp which is directly attached to redstone and B representing the redstone lamps that are blocked by a block to make sure they all light up. Make sure the area where you will place the redstone is 2 blocks long. If you are adding a second row, do a “zig zag" pattern. After this has been completed, place the minecart and test. If it does not light up, be sure to make any corrections to make it work.
- Alternate way
You can achieve the same effect, with the use of redstone repeaters. This method is often called a “redstone clock"
- You will need
- Redstone dust
- Redstone repeaters
- Redstone lamp (Or another output device)
- Switch of any sort
- Step 1
Arrange the repeaters and wire into a loop, set a delay of your choice. (note the lamps need 2 ticks before they turn off, and have no delay turning on)
- Step 2
Hook up the output device.
- Step 3
Activate and quickly deactivate or destroy the switch to create an on-and-off continuous cycle of redstone power.
As with many other redstone mechanisms, Flashing Redstone Lamps mechanism is open sourced. In this section, you will learn how to customize it for your preferences.
- Duration of delays between each flash
The simplest way to change how fast the flash between flash changes is to change the track distance. The longer the track has to go, the longer the delay. In contrast, the shorter the track, the shorter the delay will be.
- Compact design
If you'd like to make your creation in a fun-sized package, you will have to place all the redstone torches for powering the Powered Rails below it. Then, be sure to have the detector rails power the redstone torches to the middle in a way that it does not interfere with the rest.
- One flash
In this variant, all of the lights will flash at the same time. To achieve this, you must connect all the detector rails to one redstone torch that is on top of a block, in the middle, via redstone. Repeat the previous method of placing a block on top, and placing another redstone torch. Place the final block on top that will contain the redstone, and connect it to the lamps. For the effect to be noticeable, you may need to expand your tracks.
