RA: Redstone Additions
by ericsamonkey
RA: Redstone Additions brings XOR logic gates and a compact clock block to Forge worlds, so redstone builds can take up less space.
What it does
The mod introduces a set of redstone logic gates, including an XOR gate with two inputs and one output, and a clock that flips its output between off and on at a delay the player sets by right-clicking it. The author's aim is more compact redstone machines, and the gates offer one-input and side-torch layouts that differ from the vanilla designs.
Installation covers the server and each player's game. Files exist for 1.20.1 and 1.21.10, and the latest file is 1.1.0 for 1.21.10, released 2025-11-06 under the GNU General Public License v3.0 only. The code is open source, and the source code and issue tracker are linked publicly.
Key features
XOR logic gate
A gate with two inputs and one output that adds boolean logic to redstone circuits.
Compact clock block
A clock whose output flips at a player-set delay, built to save space in redstone circuits.
Side-torch logic gates
Gates with a left input, a right input and an output on the torch side, plus a one-input variant that outputs the opposite signal.
Lower memory use in tests
The author reports that a 100x100 grid of clocks, placed with WorldEdit, ran with less memory and tick time.

Use cases
Compact redstone machines
Builders can replace longer vanilla logic with the gates and clock to shrink machines.
Testing builds with WorldEdit
Creative builders can copy a stack of clocks across a large grid, as the author did in tests.
Who it’s for: Redstone builders and players who want smaller logic circuits in a Forge world. Server owners running the mod need it installed on the server and in each player's client.
How it compares
Compact Machines Infinite is a Forge mod for 1.19.2 – 1.20.1 that is also client and server and open source under the GNU Lesser General Public License v3.0 or later, so it covers a different part of the game. Universal Clock HUD (Fork) is client-side only, with Forge and NeoForge files for 1.20.1, under the WTFPL, and it does not change the redstone circuits. Cheaper Clocks is server required with client optional across Fabric, Forge, NeoForge and Quilt for 1.20 – 26.3, and is not open source.
