Write a 15-page invention notebook and wire it to a 15-lamp brain meter.
Every genius keeps a notebook. Yours lights up the lab floor, and how far depends on the page it's open to.
- New skill Reading a lectern with a comparator
- Level 6 · Inventor's Lab
- Difficulty Intermediate
- Mode Creative
- Time 30–45 min
- Ages 13+
What you’ll build
Fill a Book and Quill with wild invention ideas, one per page, and set it on a lectern in your Lab. A comparator reads the open page and lights a row of floor lamps, so you can predict, test and hide a secret in your very own brain meter.
Finish line: Your invention notebook sits on a lectern, and every page you turn lights one more lamp across the floor.
Bonus challenge: Build a second line of lamps going the other way and use two books. Can you make both meters light the same number?

Stuck?
- Lamp count doesn't match the page? Check the book has exactly 15 pages, including the cover.
- Nothing lights? The comparator must point away from the lectern, with the lamp line in front of it.
- Dust must sit on top of every lamp in the line, or the signal stops at the gap.
