13. The Jukebox Disc Key Door
What This Idea Means
Each music disc played in a Jukebox outputs a different redstone signal strength when read by a comparator. For example, Music Disc “Pigstep” outputs a different signal strength than “Cat” or “13”. Inserting a specific music disc into a jukebox acts as a unique physical key card to open your secure vault.
Materials Needed
- 1 Jukebox
- 1 Specific Music Disc (e.g., Pigstep or Mellohi)
- 1 Redstone Comparator
- Redstone Dust
- Redstone Repeaters
- Sticky Pistons
Step-by-Step Tutorial: How to Make It
- Place Jukebox: Place a jukebox in your living room area or music lounge.
- Measure Signal Output: Attach a comparator behind the jukebox. Note the signal strength produced by your chosen key disc:
- Disc 13: Signal 1
- Blocks: Signal 3
- Chirp: Signal 4
- Pigstep: Signal 13
- Signal Filter Line: Create a redstone signal length line matched to your specific disc strength so that weaker or stronger discs won’t activate the circuit.
- Connect Door Mechanics: Connect the output to your sticky piston hidden wall door.
- Operation: Insert the correct disc into the jukebox. The exact signal unlocks your secret room. Ejecting the disc locks the door instantly.
Tips and Variations
- Disc Hopper Collector: Place a hopper beneath the jukebox attached to a button that automatically ejects and deposits your key disc into a hidden chest below.
