Automatic Potion Brewer Tutorial
Automatic Brewing Station
This automated potion brewing station is easy to understand and build. You can make one for each type of potion you regularly need: perhaps one near your chicken farm to make Splash Potions of Harming, and one near your Nether to make Potions of Fire Resistance.
How it Works
When you press the button, the three potions in the brewing stand are dispensed into the chest at the bottom. All the ingredients for making the nextbatch of potions will be queued up and brewing will start.
What you will need
- 1 Brewing Stand
- 2 Chests
- 6–9 Hoppers
- 2–5 Droppers
- 7–10 Redstone Dust
- 1 Wooden Button
- 1 Redstone Torch
- 3 Redstone Repeaters
- Potion ingredients
Step by step
Loading the ingredients
When you place the Water Bottles, the first 3 will disappear immediately into the Brewing Stand. The next 5 will disappear into the Hopper. After that, the Water Bottles will fill the chest.
Push the button. Potions will be dispensed into the bottom chest. A new batch of potions will start brewing. (The first time after building the brewing station, you will just get water, but after that it should work).
Allow the potions time to brew before pushing the button again.
We use a wooden button rather than a stone button, because a wooden button generates a longer redstone signal. With a stone button, there wouldn't be enough time for all three of the potions to be released from the brewing stand.
However, this long signal causes problems elsewhere, If this signal was used to directly trigger the droppers, they would release two items each (one as the button clicks "on", and the other as the button clicks "off". This is why we need the arrangement of redstone repeaters that acts as an edge detector: a short pulse is emitted only as the button clicks "off".
