O.F.Device (Ore Farming Device)
The O.F.Device modification introduces an innovative system for automatic ore and mineral acquisition in Minecraft. The core element is a specialized device that generates various types of valuable minerals by consuming resources and fuel.

Main Device
The O.F.Device block can be mined with any pickaxe. An interesting feature is the ability to change the device's appearance using a stick.

Device Upgrades
Modifying the device significantly speeds up production and expands the range of available ores. Two upgrade levels are available.

Interface and Automation

The system operates on a simple principle:
- Materials - raw resources for processing
- Fuel - energy for device operation
- Products - obtained ores and minerals
Available Materials
- Cobblestone
- Cobbled Deepslate (for version 1.18+)
- Netherrack
- OF C Feeder I
- OF C Feeder II
OF C Feeders can replace cobblestone (at height ≥ 1) or cobbled deepslate (at height ≤ 0) and are not consumed during use. However, the OF C Feeder I consumes twice as much fuel.

Fuel
The same items can be used as fuel as for the vanilla furnace.

Interface

For automation, a hopper can be placed underneath the device to collect cobblestones.
