I stand before the skeletal frame of my future sanctuary, the wind whispering through the empty spaces where walls and a door should be. In this world of Once Human, a base is more than shelter; it is a testament to one's will, a spark of order against the creeping chaos. We begin with humble foundations, a small space that yearns to grow, and through the Memetics menu, we unlock the blueprints of civilization—structures, facilities, decorations that slowly transform a plot of land into a home. But what is a home without a welcoming threshold, a portal that knows its master? The game offers no pre-built marvels of convenience; instead, it presents a puzzle, an invitation to weave logic from light and wire. This is the art of crafting an automatic door, a symphony of components that elevates a simple entryway into a responsive guardian.

The journey does not start with a door, but with power. The first, most crucial step is to harness the sun itself. From the Logistics tab within the Memetics system, I must unlock and construct the Solar Generator. This silent, gleaming panel becomes the heart of my circuit, the source of all life for the mechanisms to come. Paired with it is the Electrical Kit, a fundamental toolkit that grants me the means to channel this energy. Without these, my dreams of automation are but idle thoughts. Can a door open without a whisper of power to command it?

With power secured, the true assembly begins. The required components are not many, but each plays a vital, irreplaceable role in the dance of automation. Let me list them for you:

  • Door Frame: The physical boundary, the canvas upon which the circuit is painted.

  • Two Pressure Plates: The silent sentinels that feel the weight of a step, the triggers of the entire system.

  • Two Switchboards: The brains of the operation, logic gates that process signals.

  • Wall Terminals & Wires: The veins and arteries, carrying the vital spark of electricity from source to sensor to switch.

  • Two Dynamic Sensors or Cameras: The eyes of the system, granting intelligence and discrimination.

  • A consistent Power Source (the Solar Generator): The unwavering pulse that keeps it all alive.

The process is a ritual of connection, a step-by-step meditation on cause and effect. First, I place the Door Frame, defining the space. Then, on either side of this nascent gateway, I install the Pressure Plates, ensuring they are directly aligned with the door's path. They must feel the approach and the departure. Next, I mount the Switchboards on opposite sides of the adjoining wall. Using the Wall Terminals, I carefully connect these boards back to the Solar Generator. A satisfying hum, a change from red to a steady, confident green on the switches—this is the moment the circuit first breathes.

Now, for the intelligence. I install the Dynamic Sensors or Cameras on both sides, positioning them so their gaze falls clearly upon the Pressure Plates. Again, with delicate wires, I connect these watchful eyes to the Switchboards and to the Plates themselves. Finally, the last connections are made: linking each Pressure Plate directly to the door mechanism on its respective side. The web is complete. A final check, a surge of power, and the system awakens.

And what is the result of this careful orchestration? A door that lives and breathes with my presence. When I step onto the plate, a signal races through the wires. The sensor confirms it is me—or one of my trusted allies—and the switchboard grants permission. The door slides or swings open, a seamless motion requiring no hand from me. It is a small luxury, yes, but in a world fraught with danger, it is profound. This is not just about convenience; it is about security. The camera sensors ensure that only recognized faces bypass the threshold. Deviants prowling outside or hostile players with ill intent find no such welcome; for them, the door remains a steadfast barrier.

My base is no longer just a collection of walls and a roof. That automated entrance is a statement. It says that here, within, order prevails. Technology serves will. The simple act of coming home is now a silent dialogue between myself and the sanctuary I have built. Every smooth, automatic opening is a quiet victory, a reminder that even in this fractured world, we can still craft wonders from sunlight and logic.
