Grand Workshop: Signalworks

Grand Workshop: Signalworks

32 functional redstone lamps: eight custom shapes in copper, iron, brass and limestone. Build wall indicators, strip lights, floor markers, pendant rings, worksite beacons, gatepost lamps, bulkhead lamps and signal totems.

Available Minecraft versions

Fabric files are available for 1.19.2, 1.20.1, 1.20.3, 1.20.4, 1.21, 1.21.1, 1.21.4, 1.21.6, 1.21.11, 26.1, 26.1.2, 26.2 and 26.3. Choose your version in Files. Features and material catalogs can differ between ports; read the selected file’s changelog before updating an existing world.

This is an active standalone expansion for Grand Workshop Core. It is also included in Grand Workshop Complete. Choose one installation style.

Light controlled by redstone

Power a fixture with an adjacent lever, redstone source or powered neighboring block. It emits light level 15 while powered and 0 otherwise, with a visibly dark lens when off. Fixtures react to power changes and consume signals; they do not produce signals themselves. They support waterlogging and rotate with the Architect Mallet or empty-hand sneak-use. Model cuboids match collision cuboids.

Crafting

Use /workshop browse signalworks or select /workshop shape gw_signalworks:<shape> with tab completion. At the material’s worktable, each fixture costs one base material, one glowstone dust and one redstone dust. You can also combine a matching Grand Workshop full block with those two dusts in a crafting table. Recycling returns the base material only. There is no free stonecutter conversion.

Install independently

Install this expansion with Grand Workshop Core and Fabric API for the same Minecraft version, on both client and server. Grand Workshop Complete already includes this collection, so use either Complete or Core plus standalone expansions. Use Java 17 for the listed 1.19/1.20 ports, Java 21 for the listed 1.21 ports, and Java 25 for 26.x. Each file’s changelog lists its required Fabric Loader and Fabric API versions. Signalworks does not require Lamplight or any other optional expansion. Retain it when continuing worlds containing its fixtures.

All gameplay texture references use original Grand Workshop 16×16 assets with at least 16 visible colors. Standalone and combined checks passed, including actual client lever interactions and emitted-light checks. Gameplay images are real Minecraft captures. Original artwork includes ImageGen-derived textures; the project logo is a branding illustration, not gameplay.

Choose files for the same Minecraft version. Use Grand Workshop Complete on its own, or Grand Workshop Core with your chosen standalone expansions; do not install duplicate expansions with Complete. Praseodymium belongs on the client only. The matching nine-project collection passed representative client/server checks across the listed versions; this does not cover every feature interaction.
