Introduction: UNIQUE SECRET BOOK SAFE

I read MANY inscrutables & posts and saw that no one had created one like the one I made .

You must have seen many books which have a secret compartment in it.BUT it is DIFFERENT.

You see this approach allows reader to read whole book keeping the secret compartment out of sight. Thus is a TRULY secret book.

Step 1: THING YOU NEED

Arduino nano (preferable) OR any other

servo moter

keypad

jumper wires

cardboard for making compartment

and MOST IMPORTANT A "BOOK"

Step 2: Get a Book!

First select a book that no-one in their right mind would ever want to read.

You will need a good thick book. Hard back is best but a paperback will also work.

if you are using paper back,then first apply card board on it and then start other steps

Step 3: Starting With Compartment

firstly ..

Dimensions of compartment will depend on size of your book spine.

Design of the compartment is shown in image.

In this compartment ,one place is for arduino and servo moter and other for keeping your things.

Step 4: Arduino Coding

Arduino code is very much easy.

For this you need

Step 5: Connection

7 to Digital 4

6 to Digital 3

5 to Digital 2

4 to Digital 8

3 to Digital 7

2 to Digital 6 1

to Digital 9

Brown to GND

Red to 5V

Step 6: Set Up Locking Mechanism Inside Compartment

To lock the Compartment, I am using a three eye screws and a locking pin. Two eye screws are mounted to the inside of the front panel of the box. A third eye screw is mounted to the inside of the lid of the box. When the lid is closed, the holes of the eye screws line up. The box is locked by inserting a pin through all three holes while the box is closed. The box is unlocked by removing the pin.

The pin is a simple piece of steel wire (straightened paperclip). It is moved by the servo. The wire is attached to the servo at one of the holes on the servo horn (actuator arm).

Step 7: Mount the Rest of the Components to Over the Book

Attach compartment to book spine.

stick keypad on cover of book.

Step 8: Covering the Book With New Cover

Picture of Covering the Book With New Cover

o hide the compartment and keypad you should cover it with paper or something which can give the book a vintage look.

After covering the book , name the book such that some letter of name are on the top of your password (number).

letters should also cover keypad's button ( A & B)

e.g. In my case

password is 14471

then

number 1,4,7 of the keypad are under letter A, 0, 1 initiated on the book

So when i will press A001A , my door of the safe will get unlocked

Make a cut on the spine of the book where the door of the compartment is. So it can get open.

note: you should cut this very neatly.

Step 9: YOUR Secret Book Is Ready
