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.
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
Memory units
Latches and flip-flops store toggle states, so a circuit can remember a signal without a tangle of components.
Insulated routing
Insulated cables, T-junctions, elbows and bridges carry signals side by side without cross-talk.
Compact logic gates
NAND, NOR, XOR and XNOR gates fit into small footprints and pass signals through without extra wiring.
Vertical transmission
An adjustable vertical repeater sends redstone signals straight up or down between floors of a build.
Locking repeaters
A bidirectional repeater holds the first incoming signal on its route, so the path stays stable.
