5. The Lectern Page-Turner Lock
What This Idea Means
Lecterns output different redstone signal levels based on which page a Book and Quill is currently opened to. By reading a specific page, a reader triggers a signal that opens a hidden bookshelf door in your library.
Materials Needed
- 1 Lectern
- 1 Book and Quill (with at least 15 pages written)
- 1 Redstone Comparator
- Redstone Dust
- Sticky Pistons
- Decorative Bookshelves
Step-by-Step Tutorial: How to Make It
- Place Lectern: Set up a lectern in your library or study area. Place a Book and Quill on it.
- Read Output: Place a Redstone Comparator directly behind the lectern facing outward.
- Set Target Signal: If you want Page 7 to open the door, extend a line of redstone dust exactly 7 blocks long from the comparator.
- Invert Signal: Put a block at the end of the 7th dust line with a Redstone Torch on top or on the side.
- Piston Door Assembly: Connect the torch output to a set of sticky pistons holding a section of decorative bookshelves.
- Operation: When players read through the book on the lectern, turning to Page 7 sends a signal length of 7, powering the block, turning off the torch, and sliding the bookshelf wall open.
Tips and Variations
- Lore Integration: Write actual custom story lore or hints on the pages leading up to the secret page number.
