LogiCycles
by GacBL
LogiCycles, a NeoForge technology mod for 1.21.1, assigns a Cycle value to items and builds a network of data centers that stores and processes those values.
What it does
Items in the world carry data, and LogiCore assigns each one a Cycle value. The value of a complex crafted item is calculated automatically from the raw materials it uses, so alchemy and other machines can make technological output without manual bookkeeping. Once an item's value is researched, it is attached to that item and is used by the network.
Data centers are built as multiblock structures from controllers, ports and frames, and their size is chosen by the player. A sealed data center with a valid multiblock arrangement is needed to run its functions, and the walls, frames and inner blocks are defined through block tags in the logicore namespace. Storage is centralized, so a single network can hold very large quantities of Cycles, and server racks supply the high-density processing that keeps the network running.
The mod requires Geckolib, and its environment is client and server, so the server and every player need it. Some machines, including the server rack and the computer, draw Forge Energy (FE) to generate Cycles, and early-game power sources are available to start that chain. The code is open source under the MIT License, and the source code and issue tracker are public. LogiCycles is published for NeoForge only, for Minecraft 1.21.1, with 1.0.2 as the latest file released on 2026-08-16.
Key features
Dynamic value calculation
Cycle values for crafted items are worked out automatically from their ingredients, so the values scale with complex recipes.
Custom-sized data centers
Controllers, ports and frames combine into multiblock data centers that the player can build at chosen dimensions.
Centralized Cycle storage
One network can store very large amounts of Cycles, replacing separate chests with a single shared store.
Server racks and power use
High-density server racks process the network, while certain machines consume Forge Energy to generate Cycles.
Guidance in game
A Patchouli guidebook and a GuideME guide include a Logic Index that documents machines and mechanics, and a reload command refreshes the cached Cycle values.

Every item in the world consists of data. LogiCore assigns a Cycle Value to items. Forget magical chests with infinite space. In LogiCore, you build physical infrastructure.
