Minecraft: Keeping an iron door open longer
October 5, 2012 1 Comment
I haven’t spent much time working with redstone circuits in Minecraft, largely because I didn’t know what on earth I needed them for, but I finally found a use. I have an iron door going through a wall into a local village. I didn’t want the villagers leaving the safety of the town (I’m a control freak like that), so I was using a button, mounted on the wall next to the door, to open the door.
The problem was that the button only keeps the door open for maybe a second. If I got the angle wrong and got caught up on the door, or if I just didn’t move fast enough, the door would slam in my face and I’d have to try again. I could often get through on one try, but I failed just often enough to go searching for a solution.
I found this neat video on YouTube, explaining how to use redstone relays to extend the duration of a button’s action:
But, unlike in the video, I want all of this to be hidden away underground, invisible, so that the button just “magically” lasts longer.
Here’s what I came up with. (Note that this is a mock-up I built in my back yard, so it’s a wooden door in an incomplete wall. I later installed this same configuration in my village using an iron door, and it works a treat.)
Once it’s built and working, just roof it over with dirt, and it’s practically invisible.
A few notes and gotchas:
- Full blocks set on point with the redstone circuit will break it; that’s why I covered the row closest to the door with wood slabs. The other side of the wall is all solid blocks.
- Redstone repeaters are directional. When you are placing them, face the direction you want the current to run.
- The circuits have several positions, which control the speed that the current flows through them. Right-click on the circuit to move the setting. The further apart the two posts are, the longer it takes current to flow through.
- To power the door, the circuit needs to end with the last section “pointing” at the door.
