How quickly can Minecraft move items from one chest to another? Faster than I realized.

Prior to Minecraft 1.5, item transfer was difficult and incomplete without using mods like BuildCraft, RedPower, or Thermal Expansion. You could use minecarts to get items from point A to point B, but you had no way to transfer items from one inventory to another, meaning items had to remain in the minecart until you moved them manually into a nearby chest (unless, again, you used a mod – specifically RailCraft). The same was true of water canals: you could move items from, say, a mob grinder to a place inside your base, but you couldn’t deposit said items within a chest. Continue reading

The bottom light means there are less than 14 items in the lower chest, the middle light means there are exactly 14 items in the chest, and the top light means there is something in an overflow hopper.

Several months ago, I came across a thread on where a player was trying to design a system that would detect if there were 14 and exactly 14 items in an inventory. In other words, he wanted one output or signal if the inventory had less than 14, a different signal if it had exactly 14, and yet another signal if it had more than 14. It is this three signal aspect that made the problem a tricky one to solve. Continue reading

Today we look at a more advanced, versatile, and intelligent minecart loading system.

Last post I talked about two simple Redstone devices that you can use to automatically load and unload minecarts if you want to use minecarts as an item transferral system. I briefly mentioned some of the limitations of the falling edge circuit as a loading system. In short, a simple falling edge circuit just isn’t smart enough to provide the versatility you might need if, say, you want to just dump a whole bunch of stuff into a chest and let the minecart system figure out how to get all those items from point A to point B. Today, I want to show you a more advanced loading and transferral system that works really well, never gets clogged, and actually gets a little faster and more efficient the more items you load into it.

This is a minecart-based furnace array. It uses Redstone powered automatic loading and unloading systems that I’ll show you in this post.

While many mods add item transfer mechanics into the game (pipes, tubes, conduits, conveyor belts, etc.), vanilla Minecraft actually has had item transfer systems built in for a long time in the form of minecarts. Back in the day (classic Tekkit and some time afterwards), if people used minecarts to transfer items it was pretty much only via additions provided with the Railcraft mod. With the MC 1.5 Redstone update, all of a sudden it became possible to load items into and out of minecarts automatically using hoppers and comparators. Today, I want to cover two simple Redstone devices that you can use to unload and load minecarts automatically. Continue reading

I’ve been doing some experimenting with horizontal dropper chains recently. Vertical dropper chains used as an item elevator are commonplace. The idea behind the vertical dropper chain is to use a comparator clock to send repeated redstone signals to a column of redstone torches adjacent to the dropper chain so long as there are items in the bottom dropper.

This is one way to set up a comparator clock to power a vertical dropper chain.

A second example of a comparator clock powering a vertical dropper chain.

However, so far I haven’t seen that horizontal dropper chains are as commonly used as vertical ones, which seems to me to be a shame, since droppers are super cheap to make and a chain of droppers can transport items very quickly. Furthermore, they can be combined with well-known vanilla sorting mechanics (using hoppers) to make sophisticated item sorting systems without the need for mods. In this post, I’m going to showcase some different styles of horizontal dropper chains and a couple of examples of sorting systems built on horizontal dropper chains. Continue reading


In my last post about my Factorization Building of Ore-Processing Awesomeness, I noted that I used Thermal Expansion Fluid Transposers to refill the water buckets that the Factorization Mixers need to do their mixing business. I did this for two reasons: 1) to save space and 2) because I’m not really a Vanilla MC Redstone stud. But something (conscience? curiosity? manic obsession with all things Minecraft?) wouldn’t let it slide. So I spent some time in my 1.6.4 modded test world and worked out a system that, if I do say so myself, is pretty sweet … if bulky. Continue reading
