How to build a minecart unloader
This build is a minecart unloader built in Java edition 1.21.5.
It is used to load a minecart to enable the use of a transport system for your items. This is joined onto the end of a minecart track and then the minecart will be unloaded into a hopper and then a chest. This works by using a comparator, the minecart will come up to the powered rail if the minecart contains items the comparator will will send a signal to the redstone torch and un-power the rail causing the minecart to stop on the powered rail. The powered rail will be placed over a hopper, while the minecart is over the hopper the items will start to empty. When the minecart is empty the comparator will send the signal and the redstone torch will re-activate and the minecart will continue on its way.

In this section we will discuss the materials and the ingredients that we need to make this build. This will give a concise list of the items and the recipe's to make them.
Hopper - you will need to craft a chest first.
Repeater and comparators - you will need to make redstone torches first.
Here we will explain in detail how to build a minecart unloader in Minecraft. Please follow the instructions carefully.






First lets place a stone block down.
Next place a redstone torch to the back of the stone block.
Place a comparator with the two prongs facing away from the stone block.
Next place a chest down like shown in the picture.
Place a hopper next to the comparator that leads into the chest.
First place a repeater on top of the stone block facing the comparator.
Attach stone block to the repeater on each side (you will have to crouch).
Finally in this section place a powered rail on top of the hopper.
Next place the rails down and a minecart.
Ensure that a standard rail is placed next to the powered rail on the hopper.
