Draft a "Main Spine" using Heavi-Watt Wire to connect all generators. Use Transformers to step down the power to standard wire for individual rooms to prevent circuit overloads and wire damage.
A Self-Powered Oxygen Machine (SPOM) typically uses Electrolyzers to split water into oxygen and hydrogen. Draft a design that uses a "gas-sorting" dome: hydrogen rises to the top to power a Hydrogen Generator , while oxygen is cooled and pumped to your base.
To ensure your base is sustainable, factor these rates into your plan: Oxygen Not Included - Tutorial Bites - Rooms oxygen not included
When creating your blueprint, prioritize these core "early-to-mid-game" modules:
Drafting a layout or "paper" plan for Oxygen Not Included (ONI) is a common strategy to manage its high complexity. Because the game requires managing thermodynamic systems, gas ratios, and power grids simultaneously, players often use external tools like or graph paper to design systems before building them in-game. Essential Systems to Draft Draft a "Main Spine" using Heavi-Watt Wire to
Standardize room heights at 4 tiles high . This allows Duplicants to reach the ceiling for construction and maintenance without extra scaffolding.
Use logic gates (AND, OR, NOT) to automate mundane tasks. For example, draft a circuit that turns off coal generators when batteries are full to save fuel. Planning Tools Draft a design that uses a "gas-sorting" dome:
Useful for quick spatial sketches of room layouts and "pipe spaghetti" management.
