During last Saturday's Weekly Workshop, we played with redstone combination locks. A redstone combination lock is a redstone device that relies on logic gates in order to power a door or some other redstone powered item. The complexity of a lock can often be determined by how many logic gates are used in conjunction with each other. We used redstone logic gates in a previous tutorial as well. Combination locks can be used to keep your loot safe on a chaos server, create fun mini-games, or test would-be griefers before they dare enter your server without reading the rules. As with all things redstone, combination locks can be extrapolated for many, many uses.
Creating a Redstone Combination Lock
In this example, we'll use an intermediate lock that can be changed either for more simplicity or greater complexity.
Step 1 Build Your Combination Array
Typically, the combination of a redstone lock is entered using levers. The lock is usually opened either by a pressure plate or stone button after completing the correct combination. We'll use levers and pressure plates in this example.
Step 2 Build an And Logic Gate
All redstone gates transmit a signal based on a certain set of requirements. A redstone And logic gate is named as such, because it requires two redstone signals to be sent to it simultaneously in order to send a final signal. This means that our combination above will have to be right in order to help activate one half of the And Gate.
Step 3 Connect the And Gate and Combination Array
Step 4 Add a Second Redstone Activator
The And Gate still needs a second redstone signal in order to be activated. This will be the final step needed to open your door or other redstone activated devices. This can be a button, a pressure plate, or a lever.
Step 5 Complete the Lock
Now you can breath easy keeping unwanted beings out and your favored items in. A special thanks to everyone who made this workshop an awesome one!
