Pulse Circuits

PULSE EXTENDER

Takes a short input pulse and extends it to a longer output duration. Uses repeater chains, comparator loops, or sticky pistons to hold the signal for a set time.

When to Use

Making button presses last longer, keeping doors open for a set time, extending observer pulses for slower circuits.

Materials

  • Multiple Redstone Repeaters
  • Redstone Dust
  • Solid blocks

How to Build

  1. 1Simple method: Chain repeaters in series from the input to the output.
  2. 2Each repeater adds 1-4 ticks of delay.
  3. 3The output stays on for the original pulse length PLUS all repeater delays.
  4. 4For very long extensions, use a sticky piston holding a redstone block.
  5. 5The piston extends on the pulse, and the redstone block keeps the circuit powered until the piston retracts.

Variants

  • Repeater chain (adds fixed delay, easy to adjust)
  • Sticky piston + redstone block (long extensions)
  • RS latch with delayed reset (toggle on, auto-off after delay)
  • Comparator fade-out (signal strength gradually decreases)
