Electromechanics
by chyzman
Electromechanics extends the Redstone system with wires, slime blocks, gates and observers that link electrical and mechanical logic in one mod, for Fabric.
What it does
The mod adds colored redstone variants that connect to one another, letting builders run closer wires that carry different signals side by side. Colored slime variants share the design of the vanilla slime block and open more options for moving parts, and a slime slab variant gives slimmer mechanisms.
Expanded gates add operations beyond the vanilla set, including basic boolean logic and more complex functions such as multiplying modules and timers that switch output direction. Expanded observer variants can watch changes to NBT data and react to neighboring block updates. The name joins electrical and mechanical aspects, and both are developed within the mod.
Electromechanics needs Fabric API and oωo (owo-lib). Servers that run it need every player to install it too. Files are published for Fabric only, across five release versions 1.20 – 1.21.1, under the MIT License, and the source code is open source.
Key features

Use cases
Who it’s for: Redstone builders and technical players who work with contraptions and logic circuits on Fabric. Server owners who want these blocks available to players need to install the mod on the server as well.
How it compares
Midrian - Redstone Revolution is also a Fabric mod that runs on client and server under the MIT License, but it is not open source and covers 1.20.1 – 1.21.11. Freeze Observers is a Fabric mod for 1.20.1 – 1.20.2 that is server-side only, so players join without installing it, and it is open source under the MIT License. slime ++ is a Fabric mod for 1.21 – 1.21.1 that runs on client and server and is not open source. Electromechanics covers a wider range of versions than Freeze Observers and slime ++ while sharing the client and server environment with them.
