You enter a study and see a lightbulb hanging on the bookshelf. You try all the switches in the room — nothing is turning it on. Remembering you’re in [lonesoulsurfer]’s home, you realize that you’re going to have to start yanking on every book in sight.
While often associated with the likes of Bat-caves and other complicated hidden passageways, turning a shelved book into a secret switch isn’t complex in its own right. [lonesoulsurfer] is basing their build on one by B.Light Design revolving around a fan switch, some aluminium strips, a block terminal, fishing line, a hinge, and — of course — a book with a dust jacket and something to trigger.
Bend the aluminium into an angle bracket and drill a hole to attach the fan switch — ensuring the whole is small enough to fit behind and not distinguish the book you’re using. Cutting the hinge to the size of the book and screwing a strip of aluminium to it, both this lever and the fan switch’s bracket are then mounted on the shelf. Once a length of fishing twine is tethered to the lever and fitted through the book’s pages to the fan switch — ensuring the line is taut — sliding the dust jacket back onto the book completes the disguised switch!

We have very few books hanging around the house which makes this small attractive assembly quite enticing. It was built by [Eric Whyne] who wanted to make sure the casual observer didn’t think it was store-bought. In choosing wood he tried to find a couple of show pieces with visually appealing flaws like the broken out knot seen on the bookend.
In addition to the blemish, he chose joinery techniques that would show off craftsmanship not generally found on mass-produced goods. And we’d say he succeeded. The rails attach to the end pieces using a mortise and tenon joint with a wedge to hold things tight. It’s similar to how an ax handle is mated with the blade. The mortise gets a bit of a flair, and a slot cut in the tenon is forced to grip that flair using a small wooden wedge. Here’s an in-depth description of this type of joint.
We just have to mention that we endorse his reading selection. Snow Crash and Burning Chrome are among our favorite novels.
Taking on a giant build just to hide your shotgun collection may seem a bit over the top. But we couldn’t be more impressed with the project. [Korostelevm] did an amazing job of hiding a small closet with a bookcase-door. It’s something straight out of a Hardy Boys novel.
Possibly the most important part of the build is figuring out how to hinge all the weight a bookcase will carry. His solution was to use a set of four heavy-duty casters. He cut off the wheels from one pair and the mounting brackets from another. By welding the brackets on in place of the wheels he has a sturdy way to mount both the frame and the bookcase. When closed the unit latches using a strike plate and lock set from a door. This is connected to a book using some cabling and pulleys. As you’d expect, just find the right hard-cover and tilt it toward you to open the hidden storage behind. [Korostelevm] shows off the final product after the jump.

Want to enter your hidden lair in style? Well [Jimmy] simply wanted to create a cool prop for his school’s homecoming dance. This project includes some obvious inspiration from Wayne Manor. [Jimmy] wired up the automated entrance with a 12VDC motor. In order for it to be able to push the door , the motor had to be attached to a gearbox, which directly powered a wheel. Current consumption issues were solved by using a wall-wart. Because a real bookshelf would still be too heavy, [Jimmy] dressed up a regular door with some patterned wallpaper to give it the right look. Coupled with a Shakespearean bust concealing the button, and some other cosmetic touches, this project was sure to impress any student who knew its secret.
