Logic Circuit notes

• When two inputs are powered, the output gives power based on the longer of the two input distances.
• When one or three inputs are powered, the output gives no power.
• A signal that arrives at strength 1 does not count as a powered input, unless its source itself outputs strength 1 (like an Electricity Stick).
• Putting an Electricity Stick on one of the inputs changes how the logic gate behaves.
• Feeding a generator into one input and a weakened signal into the other extends that signal.

These notes cover behavior that the game files do not show directly. They are based on facts from the Core Keeper Wiki (Fandom) page "Logic Circuit" (CC BY-SA 3.0), rewritten in this site's own words.

What you get from salvaging Logic Circuit (Salvage and Repair Station)

Logic Circuit can be salvaged. Salvaging it gives the following items.

• Scrap Parts×1
• Copper Bar×0-1

For each material, the amount is "amount used to craft × 0.49 (lower when durability is down, 0.3 at 0 durability) × the item's multiplier", and a fraction is the chance of one more (2.4 means 2, with a 40% chance of 3). The range is from 0 durability to full durability (items without durability always count as full). Scrap parts are a fixed number set by the item level. All items that can be salvaged are listed in salvaging.
