Pulse Circuits

PULSE LIMITER (SHORTENER)

Takes a long input signal and shortens it to a specific pulse length. Useful for converting lever toggles into brief pulses or limiting piston extension time.

When to Use

Converting toggle switches to momentary pulses, preventing piston doors from staying open, timing-critical circuits.

Materials

  • ▸1-2 Redstone Repeaters
  • ▸Redstone Dust
  • ▸1 Redstone Comparator or Torch

How to Build

  1. 1Split the input into two paths.
  2. 2One path goes directly to one input of an AND gate.
  3. 3The other path goes through a delay (repeaters), then through a NOT gate, then to the other AND input.
  4. 4The output is only ON during the window before the delayed-inverted signal arrives.
  5. 5Adjust the repeater delay to set the output pulse length.

Variants

  • ▸Repeater + comparator limiter (precise timing)
  • ▸Torch-based pulse shortener (1-tick pulses)
  • ▸Piston cutoff (piston physically breaks signal after delay)
