A semi-automatic wheat farm using the observer block _ mine, build, eat, repeat

Quite a lot of Minecraft farm automation depends on different mechanisms or exploits to detect changes in conditions or status. Link between sugar and cancer For example, automatic sugar cane farms rely on a block update detector to trigger a line of pistons once one of the sugar cane plants has reached a particular height. Sugar you are my candy girl Auto pumpkin and melon farms often use the fact that pumpkin and melon blocks transmit a redstone signal to connect a broken line of redstone once the plant produces the pumpkin or melon on a specified block.


Up until Minecraft 1.11, however, it was impossible to automatically detect when a wheat plant had matured, because changes in the wheat plant’s development for some reason did not constitute a full block update. Sugar cane growers cooperative of florida Instead, one had to rely on a long term timer to approximate when a field of wheat would likely be mostly mature. That sugarcane that tasted good This method worked, but I never really felt it was ideal.

All of that has changed with the introduction of the Observer block in Minecraft 1.11. Sugarcane restaurant miami The Observer block is more sensitive than a block update detector because it detects not just full block updates but even changes in the basic block state, or the block’s metadata. Maui sugar cane train This includes changes in the stage of maturation of a wheat plant.

In other words, an Observer that faces a wheat plant will emit a redstone pulse every time the wheat plant matures into a new stage. How to plant sugar canes in minecraft This makes it possible, using a redstone counter, to detect when a single wheat plant has matured. How to grow sugar cane from seed If we are using a standard 9?9 wheat field setup (with a water block in its center, covered by a stone slab), the wheat plants that will grow the slowest are those on the corners. Sugar cane in spanish So if we use an Observer to detect the growth of a corner plant, more than likely most of the wheat plants in the field will have reached maturity when the Observer emits its last redstone pulse.

Allow me to use pictures to explain. How to plant sugarcane in minecraft Detecting When a Wheat Plant Reaches Maturity

Adjacent to my ugly vanilla house, I now have a basic 9?9 farm surrounded by Oak Leaves blocks (rather than fence posts so that auto-harvested wheat stays above the farmland blocks … and because it looks cool). Palm sugar vs cane sugar The shed in the upper corner houses the Observer and some redstone magic.

This is the observing side of the Observer block, facing the corner of the wheat field that is most likely to grow the slowest.

Behind the Observer I have a redstone counter to count seven changes in the state of the wheat plant. Corn sugar vs cane sugar Wheat plants have eight stages, with a newly planted plant being stage one, so the state changes seven times. Where to buy sugar cane I adapted this counter from a design by MumboJumbo. Where to buy sugar cane stalks You can see his video here.

MumboJumbo’s counter begins with a basic monostable circuit, but we don’t need that here. Where to buy sugar cane juice A monostable circuit makes it work with any kind of redstone input, even solid ones like levers. Sugarcane in brazil But because our input is already going to be in the form of 1-tick pulses, we don’t need the monostable circuit.

The Repeater must be on 2-ticks, otherwise the redstone torch will not depower.

All we need to do is place a Repeater on 2-ticks directly behind the Observer leading into a NOT gate (i.e., a redstone torch). Sugar cane processing flow chart The 2-ticks setting is necessary, because the 1 tick pulse of the Observer is not sufficient to depower a redstone torch. Define sugarcane The redstone torch powers a line of redstone dust that sits on top of (the majority of) a loop of Hoppers. Sugarcane production in india An item that has been placed in the first Hopper (after the wheat seed is planted the first time) cannot move to the next Hopper until the redstone signal is turned off by the Observer’s pulse. Sugarcane production by country Every time the Observer detects a change in the state of the wheat plant, its pulse turns off this redstone signal, allowing the item to move to the next Hopper. Sugarcane planter In this way, we can count how many pulses (i.e., changes in state of the wheat plant) have occurred.

The Hopper loop that counts the stages of wheat growth. Nutritional value of sugarcane The Observer is down and right from the edge of this pic. How to farm sugar cane in minecraft The redstone torch in the background is something different. Sugarcane nutrition facts A single item is placed in the Hopper in the bottom left of this pic after the initial planting of wheat.

Not only does the change in the wheat’s growth stage trigger the Observer, so does the appearance of water (my method for harvesting), the disappearance of that water, and, obviously, the planting of a new seed.

A single item (it doesn’t matter what) is placed in the first hopper after the wheat has been planted. Nutritional value of sugarcane juice This can be done manually or through a reset button or system. How to make sugarcane juice at home My design resets automatically.

Upon the seventh pulse from the Observer (meaning the wheat plant has reached maturity) the item goes into a hopper that has no piece of redstone on top and therefore no redstone signal disabling it. Is sugarcane juice good for health As it passes through this hopper, a Comparator detects the presence of the item and emits a new redstone signal. Sugar cane juice nutrition facts This signal will ultimately trigger two separate mechanisms: a harvest mechanism and a gathering system.

This latest redstone signal splits in two. Benefits of sugarcane juice in hindi One direction (going off to the right in the picture) triggers my collection system. Sugar cane cutter The other connected to the redstone torch on the left) triggers my water harvesting system. Sugar cane spider Auto-Harvesting With Water

I use a Dispenser with a water bucket placed above the center of my wheat farm to harvest the mature wheat. Sugar cane for sale To make this work, we have to send the redstone signal generated by the maturing of the wheat up to the Dispenser and split it into two separate signals: one to pour the water and one to stop the water. Sugarcane benefits in pregnancy There are different ways to do this. Sugarcane harvester price in india Here’s how I did it.

When the wheat plant reaches maturity and triggers the second redstone signal, this system effectively sends two separate pulses to the Dispenser, turning it on and then off again long enough to break all the wheat plants and send most of them to the sides of the wheat field. Sugarcane farming in india All that’s left is to harvest them. Is sugarcane a fruit I use a Hopper Cart directly under the farmland to collect the wheat. Sugarcane cultivation in india Because Hopper Cart harvesting is a concept that really could be used in other projects (and because this post is already running a little long), I’ve posted about that separately here.

One last note: this exact setup can also be used for farming potatoes and carrots. Sugarcane australia Even though they appear to have only four growth stages, in fact they both have eight growth stages, but some of the stages use the same graphics. Is sugarcane good for you To farm beetroot would take a slight modification, because it only has four growth stages in actuality, so you can either use fewer Hoppers or simply remove the redstone from four of the Hoppers. Sugarcane juice machine price The same goes for Nether Wart on Soul Sand. Is sugarcane juice good for diabetics So the Observer block used with a redstone counter system (and there are others that are not so iron intensive) opens up a whole world of Minecraft automation that was unknown before 1.11.
