Rust auto furnace circuit

A conveyor fills a furnace from a box: wood goes into the fuel slot and ore into the input slots on their own. A second conveyor empties the output slots into another box. The furnace has to be lit with wood inside and goes out when it runs out.

How to wire it

  1. Medium Rechargeable Battery "Power Output" → Splitter "Power In"
  2. Splitter "Power Out 1" → Industrial Conveyor "Power In"
  3. Splitter "Power Out 2" → Industrial Conveyor "Power In"
  4. Large Wood Box "Industrial Out" → Industrial Conveyor "Industrial Input"
  5. Industrial Conveyor "Industrial Output" → Furnace "Industrial In"
  6. Furnace "Industrial Out" → Industrial Conveyor "Industrial Input"
  7. Industrial Conveyor "Industrial Output" → Large Wood Box "Industrial In"

How Rust electricity works

Power in Rust is pushed, not pulled: a source sends everything it makes down the wire, and each component decides what to pass on. A splitter divides what comes in evenly between the outputs that have a wire, without looking at what each one needs; whatever isn't used is lost. A branch sends a fixed amount out of Branch Out and the rest straight on.

Batteries are the exception that makes bases work: a battery always pushes its full output (15, 50 or 100), but it only spends what the things wired after it actually use. That's why a battery feeding a turret and a light through a splitter drains 11 per second, not 50. It charges at 80% of what comes in.

Most components that only route power use none: splitters, branches, switches, timers, counters and logic gates. Lights, sensors, RF and door controllers use 1, the auto turret 10, the SAM site 25. A component that gets less than it needs doesn't run and doesn't spend anything.
