Circuit

Circuit is a Fabric mod for designing and placing redstone circuits from a visual (in-game) editor.

Instead of building every gate directly in the world by hand, Circuit lets you open a top-down circuit editor, place redstone components on a grid, connect them with wires, organize larger builds into modules, and then sync the result into your Minecraft world.

Features

• Top-down redstone circuit editor
• Simple and detailed viewing modes
• Place logic gates, wires, repeaters, clocks, latches, flip-flops, inputs, outputs, encoders, decoders, and larger structures
• Import and save .bcdi circuit files
• Preset support for larger example circuits (one yet)
• Module system for grouping circuit sections into reusable blocks
• Multi-layer editing for vertical redstone layouts
• World sync to place the circuit into Minecraft
• World scan to detect redstone changes made manually in-game
• Smart wire handling for routing, crossings, observer wires, and repeaters
• Redstone-focused flat world workflow for testing builds

Why Use It?

It is useful for:

• planning redstone computers
• experimenting with logic gates
• building reusable modules
• creating larger circuits before placing them in the world
• organizing technical redstone projects

The goal is to make redstone feel easier to design while keeping it connected to Minecraft builds

Environment

Circuit is required on the client but also recommended on the server.

For multiplayer, the mod is also required on the server if players should use world-sync features that place or modify blocks through the mod workflow. For singleplayer, installing it normally in the client/modpack is enough.
