I must release the hordes of knowledge Ok enough of that lets get to work. 1st step - Place your chest You don't need to raise it off of the ground. You need a 1 block drop behind it for the next step. Step 2 - First hopper and torch The torch is powering the hopper. A powered hopper doesn't transfer items. Step 3 - The comparator and the 2nd hopper Place the comparator pointing away from the chest. The make the hopper feed into the comparator Step 4 - Add the 3rd hopper Note: this is for a single set up. If you want more than one please refer to the tillable section for details Step 5 - Redstone 5A) Add the two back stones to this setup and top with redstone dust. 5 B) Place a repeater under the dust. Make sure it is facing the torch Step 6 - Sorting Filter Place 21 cobble or 21 of an item you wont miss into the hopper. Add one of what ever you are sorting. Note: Don't add cobble or substitute to this system. It will go into the first chest it will find filled. Step 7 - Repeat You can use a trap chest to compact it like so However, do not open the trap chest until sorting is done. It locks up the system. Youtube videos I used to learn.
