2x2 Hallway Door

In this video, we break down a 2x2 piston door that opens layer by layer in a way that’s simple, elegant, and a bit unconventional. Instead of just giving you a tutorial, we walk through the thought process behind the design, showing how timing, signal strength, and series circuits come together to make the door work.
You’ll learn why basic repeater chains don’t scale, how to sequence pistons using incremental delays, and how a pulse extender can control which pistons activate by letting the signal decay over time. Plus, we’ll explore how to extend the design for longer doors using modular segments.
Whether you’re learning Minecraft redstone, want to build a clean double-height door, or just love understanding how unique redstone contraptions work, this video will give you both the intuition and the skills to think like a redstone engineer.

What you’ll take away:
How to control piston sequences with incremental delays
The difference between series and parallel circuits in redstone
How pulse extenders can be used in non-standard ways to manage signal strength
Techniques for scaling your door for longer builds
