Configs

The configuration file for the mod, circuits.cfg, is stored at [Minecraft directory]/config/circuitsMod/circuits.cfg. It's got pretty okay inline comments, but things you can configure:
 * Whether circuit crafting is collaborative (one player unlocks -> everybody unlocked a circuit) on a server
 * The maximum number of automatically-generated test cases to run on combinational circuits [default: 32]
 * The maximum number of exhaustive input cases to allow for custom circuits [default: 32]
 * Whether or not the configuration options string will render on every Circuit Block
 * The cost computation function for crafting recipes resulting from successful Control Block#Testing.
