In this instructable, I will show you how to make a tissue box safe that can be unlocked by your iOS device. Trick your friends, family, or intruders with this hidden space.

Step 1: Materials

Picture of  Materials

Kleenex box (1)
Cardboard (metal or wood for a heavy duty box)

Needed for lock system:
Arduino (1)
Breadboard (1)
Solenoid lock (1)
Bluetooth LE breakout board (1)
Darlington transistor (1)
Red and green LEDs (1 of each)
220 ohm resistor (2)
12 V 1000+ mA power supply (1)

You may also need:

Hot glue gun
Exacto knife (if you use metal or wood saws may be required)

Step 2: Cut the Cardboard

-I used cardboard, but I would recommend lining the box with metal or wood so that it is more durable. To start off, use your exacto knife to cut the end of the box off.

-Then measure cardboard to fit all around the inside the box to make it stronger.

-Make three layers of cardboard for the bottom and four layers for the end you cut off.

-Make sure you cut the cardboard a little shorter in length than the box.

Step 3: Glue

-Again, this step will be a bit different if you use metal. I would recommend welding the seams. For cardboard, glue the layers together.

-Glue the cardboard in the box to line it.

-Then glue the top layer of cardboard a bit lower than the top to store a few Kleenex in it.

Step 4: Hook Up the Arduino and Breadboard

Follow the steps from this DIY if you want your box to lock.


Step 5: Connecting the Lock to the Box

1- cut a hole for the lock

2- tape or glue the lock to the cut off end.

3- poke hole in side to fit power chord for Arduino

4- use tape as a hinge or get a hinge for the top or side of the opening.

5- slide all the electronics into the box

Step 6: Using the Lock

You are now able to control the lock from your phone! You can now keep your valuables safe in your locked secret tissue box!

The idea is that you could line the box with anything such as metal or wood. I used cardboard because it was all I had available.

It's a cool idea, but shouldn't the wall's be reinforced with something stronger than cardboard? Otherwise, if someone was to become aware that you were hiding valuables in a tissue box they could simply rip it open and the lock won't matter. If anything the lock makes it more likely to be discovered as it adds obvious weight without actually adding any security.
