Mercury Digital

by TC__Mercury

Mercury Digital adds compact, edge-triggered logic circuitry to Minecraft, so players can replace large redstone contraptions with simple memory cells.

NeoForgeClient and serverAll rights reserved1.21 – 1.21.11

What it does

Players who build with redstone often end up with large, messy arrangements to store a single toggle state. Mercury Digital supplies latches and flip-flops that hold a state reliably, along with logic gates that compute signals in a few blocks. The mod is aimed at engineers, automation fans and redstone tinkerers who want circuits closer to real-world digital electronics.

Routing is handled by insulated cables, T-junctions, elbows and bridges, which keep signals from crossing each other. Vertical repeaters send a redstone signal straight up or down, and bidirectional repeaters lock onto the first incoming signal along a route. The mod is published for NeoForge only, under All rights reserved, and runs on client and server, so the server and every player need it. Files cover 12 release versions in the range 1.21 – 1.21.11, with 1.0.2 for 1.21.11 as the latest build.

Key features

  1. Memory units

    Latches and flip-flops store toggle states, so a circuit can remember a signal without a tangle of components.

  2. Insulated routing

    Insulated cables, T-junctions, elbows and bridges carry signals side by side without cross-talk.

  3. Compact logic gates

    NAND, NOR, XOR and XNOR gates fit into small footprints and pass signals through without extra wiring.

  4. Vertical transmission

    An adjustable vertical repeater sends redstone signals straight up or down between floors of a build.

  5. Locking repeaters

    A bidirectional repeater holds the first incoming signal on its route, so the path stays stable.

Use cases

Who it’s for: Engineers, automation enthusiasts and redstone tinkerers who build digital logic in survival or creative worlds. Server owners who run automated builds need the mod on the server as well as on every player's client.

Questions

Does Mercury Digital need to be installed on the server?

Yes. Installation covers the server and each player's game.

Which loader does Mercury Digital support?

Only NeoForge. The latest NeoForge file is 1.0.2 for 1.21.11, and files exist for the game versions listed on this card.

Can Mercury Digital circuits be used in an older game version?

Not with this listing. The earliest published files target 1.21, so older game versions are outside its range.
