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
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
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
libraries : Password click here,
Step 5: Connection
keypad to arduino connection (refer image)
8 to Digital 5 of Arduino
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
Servo Moter to Arduino connection (refer image)
Orange to Digital 12
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
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
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.
