Tutorial written by Seikatsu.
To get started, you will need the following items:
|Any Building Block||x12|
|Any 64-Stackable Item||x19|
|Bottle o' Enchanting||x22|
Step 1 Edit
Create the following "T" shape using the building blocks and place two torches on the left side.
Step 2 Edit
Place two redstone dust on the bottom part of the "T" and a redstone torch on the top part of it.
Step 3 Edit
Place an upside-down slab on the most-left block, a hopper facing away from it (to the left) and a chest, connected to the hopper. That will be your output chest.
Step 4 Edit
Place a comparator on the slab, which is facing to the right and into a block. You will also need to place a hopper to the left of the comparator. The hopper must be facing into the comparator!
Step 5 Edit
A block can be placed on top of the comparator next, along with a hopper pointing into the one below it. The hopper will be your Experience Tank.
Step 6 Edit
Go to the highest hopper and build a little platform behind it. This will house most of the circuiting.
Step 7 Edit
Place a comparator facing out from the future Liquid Tank, run some redstone out of it, and make it run into a repeater set to 4 ticks.
Step 8 Edit
You can then place a hopper pointing into the future Liquid Tank and a chest on top of it. The chest will be your input.
Step 9 Edit
Now that you have built the structure, fill the hopper facing into the comparator like shown below. After that, turn the hopper above it to a Liquid Tank and set it to Fill Mode and add 1 Lapis Lazuli. That will convert it to an Experience Tank.
Step 10 Edit
Re-configure the Liquid Tank once again by replacing the sign by any stackable item and change the hopper to a dispenser. This will allow you to fill empty bottles with XP.
Step 11 Edit
Now go ahead and give the whole thing a test with multiple bottles. If they get through, you've built it right!
