Repeatable example: using circuits to set the recipe on a foundry:
- Flips the pipes to the right side when set to Cast Iron (inputting fluid).
- Flips the pipes to the left side when set to Molten Iron (outputting fluid).

Reason this is an issue: trying to make a compact, circuit-controlled ...

Idea: an airship/blimp/zeppelin that can be given stations for safe automatable cargo transport over water, cliffs and hostile forces.

How it may work: I don't know how to code, so I'll list a few methods that may work.
1. Stations (mooring mast) if you tell an airship to go from station A to ...
