The Circuit Progression
Circuits gate nearly every advanced machine in Prodigy Tech. The chain runs 
Crude Circuit → 
Refined Circuit → 
Perfected Circuit, and each tier needs its own pattern item plus processed materials.
Crafting Each Tier
1. Crude Circuit — combine a 
Crude Circuit Pattern with basic refined materials. This is your first circuit and unlocks early machines.
2. Refined Circuit — use the 
Refined Circuit Pattern with better inputs, typically involving 
Carbon Plate and refined dusts. Carbon Plates come from compressing 
Coal Dust.
3. Perfected Circuit — the 
Perfected Circuit Pattern requires the most processed inputs, including Ferramic components and higher-tier dusts.
Supporting Materials
You will need a steady supply of Carbon Plate (from Coal Dust), 
Ferramic Ingot and 
Ferramic Gear (from 
Ferramic Dust), and various refined dusts. Set up a 
Heat Sawmill for wood byproducts like 
Sawdust, and use the 
Ore Refinery for metal dusts. The 
Atomic Reshaper and 
Magnetic Reassembler convert dusts into plates and ingots.
Practical Tip
Do not hand-craft circuits one at a time once you have the patterns. Build a small production line: dust refining feeding into reshaping, with a stockpile of Carbon Plates. Circuits are consumed constantly by machine recipes, so batch production saves enormous time.
