Build a crypt whose door opens by itself at night and seals at sunrise.

By day the crypt is sealed tight. When the sun sinks below the hills, the stone door grinds open on its own…

  • New skill Using a daylight sensor

  • Mode Creative
  • Time 40–60 min
  • Ages 13+

What you’ll build

Build a spooky crypt with a stone piston door and put a daylight sensor on the roof. By day the door stays sealed; as the sun sets it grinds open all by itself. Time sunset and sunrise, then test whether a longer wire changes anything.

Finish line: Your crypt door opens by itself at nightfall and seals at sunrise, with the real times written down.

Bonus challenge: Make the crypt need a night AND a secret button: only open at night when the button is pressed. Hint: it's like the two-key vault.

You’ll need

  • Daylight sensor
  • Sticky pistons
  • Redstone dust
  • Crypt blocks
  • A bed
  • A clock or timer

You choose

  • My vampire's name
  • Crypt style: spooky stone, deepslate or
  • What the vampire guards

Stuck?

  • Door won't seal by day? The sensor needs open sky above it, with no blocks in the way.
  • Behaving backwards? Tapping a daylight sensor switches it to night mode. Tap it again.
  • Bad weather lowers the sensor's signal, so test on a clear day.
