Clock Circuits

OBSERVER CLOCK

Two observers facing each other create the fastest possible clock. Each observer detects the other's state change, causing infinite rapid toggling at 1 game tick per pulse.

When to Use

Fastest possible clock for rapid-fire dispensers, bubble column activators, zero-tick farms (if applicable).

Materials

  • ▸2 Observers

How to Build

  1. 1Place one observer facing any direction.
  2. 2Place a second observer facing the first one (faces pointing at each other).
  3. 3They immediately start toggling, each detects the other's state change.
  4. 4Tap the output from the back of either observer.
  5. 5Warning: This creates extreme lag if overused. Use sparingly.

Variants

  • ▸Direct 2-observer clock (fastest, 1 game tick)
  • ▸Observer + piston clock (slower, more controllable)
  • ▸Observer chain clock (sequential observers for timing)
