Picture of Sexy Secret Book!
Just in time for Valentines Day! There are plenty of secret hidden compartment book projects but I added a special high-tech bonus feature that has never been done before!

Step 1: Get a book!

If it's anything like the book I found in the used book store, you will want to read it cover to cover. After that, using a ruler mark off a decent sized square area and cut it out all the way to the back cover using an X-acto knife or razor blade(s)

Step 2: Finish Compartment One

To seal the pages and the back, I used hot glue as it seemed to be a better option than all the messy glue mixtures I have seen on some projects. I also used a piece of self-adhesive red felt to line the main compartment.

Step 3: Compartment Two

Now on to the second compartment which will house our electronics. Once you have the components you will be able to determine the best size for the final fit. Cut out the compartment like you did the first one but not nearly as deep. You only have to cut it out as deep as a 9 volt battery. Notice I also cut back one page and left a 'door' that will cover the 2nd hidden compartment.

Step 4: Build the 'secret' feature...

What you need...
1. Radio Shack (or other brand) voice recording module.
2. 9 volt battery
3. SPDT Lever Switch
4. 1/8" Phone Jack

Remove the button attached to the circuit board by peeling back the three clips that hold it in place. Then solder two wires to the contacts on the circuit board and solder the lever switch to the other ends. Be sure to use the N.C. or Normally Closed contact.

Step 5: Finalize the module...

The recording module comes with it's own microphone so you can record your voice, but I wanted to take it a step further, so I added a 1/8" phone jack to the microphone connections so I could record anything onto the module up to 20 seconds long. J4 and MIC are the microphone connections shown in the image.

Step 6: Install the module...

I installed the module in the 2nd compartment and used hot glue after double checking the location and lever operation when closing and opening the book.

Step 7: Record your audio...

You can record whatever you want on the module as long as it's no longer than 20 seconds. It sounds remarkably well considering the size of the speaker. The compartment serves as a basic enclosure. When you are done having fun with it, use it as a real secret book safe and add an alarm sound effect! Hope you enjoyed this Instructable!

OK, not to be nosy, but what exactly was that book about? Just the words I can read made me blush a little. :)
I'm guessing blow*jobs?
Lol, "Testicles", "Passion", "not to swallow yet", "press your own nipple" lol

Kipkay (i have been a fan for years) You have the best hacks and sometimes the funnest presentations, bar none. Guys and gals I think the book is " The Velvet Tongue ". To speed up the process try this instructable: http://www.instructables.com/id/Better-Book-Safe/?ALLSTEPS

An couple ideas to try when making these books is (1) don't use a good book that anyone might want to read. Wasting good books is bad, Mkay? and (2) you can drive nails into the area you plan to cut out to hold it together, then drill a large hole near a corner and use a metal cutting hacksaw blade to make the process go faster.
I used a dremmel to cut my book i used to hide my passports in when i went to rome and that cut very straight, i just clamped it to my desk and started chopping.

Hi Kipkay

did you use a specific program to upload your sound clip? or play the clip on your computer and use the record feature on the recording module? could you also specify what type of cord you used to hook up to your computer and what port in your computer it hooks up to? sorry for the many questions.

thank you, this will really help me with something I'm working on.

What Happens if the battery is removed? Does the sound get erased?

what book was it
Heh, I was wondering that too. I've been wanting to hollow out a book for a while but just can't bring myself to distroy one.
sometimes libraries give way old books.
I'm pretty sure it's that 101 Nights of Grrrreat Sex book. And since most of my lovers are more creative than the authors, I say, yeah! cut that book up!

With a bit of amplification, and distortion correction/modulation, that "RS module actually works well :-)
