Buy book shelf online from Urban Ladder and save yourselves from the burden of not just stepping in and out of countless stores, but also the hassle of assembling it. You can find all these and more on Urban Ladder. And if you love experimenting, check out quirkily-colored ladder book racks. But if you love clean edges and minimalist flourishes, a glass door bookshelf with a wooden finish that complements neutral walls works best. Save your time and space with a wooden bookshelf in your living room that ties neatly with traditional decor and is reminiscent of the past. And a bookcase can be a decorative piece in and of itself as well, especially when matched to the rest of the furnishing and decor of the room. These pieces of furniture keep your books from unnecessary wear and tear as well. If you are a fan of fantasy or an avid non-fiction reader, a bookshelf is essential to not just organize your prized possessions but also to proudly display them. One PIR sensor (used as an interrupt when motion was detected).Īll components and power supplies were located on a shelf next to the door on the inside.Buy Wooden Bookshelves Online At Low Prices On Urban Ladder.One outside switch (attached to a DVD cover to keep it hidden).Two manual switches (attached to the inside of the door).The switches/sensors were attached to the inputs on the Arduino and included: A RobotPower Multimoto high power quad motor shield provided the power control to the four linear actuator motors. ![]() Additionally, it controlled triggers on the motor driver. When a finger/arm gets caught in the door or when a power failure occurs, the door can be pried open, which will dislodge the magnetic linear actuator connection.Īn Arduino Uno was responsible for all inputs and outputs. To create a pinch-free door and to be able to open the door in case of a power failure, the shaft ends of the linear actuators (responsible for opening the doors) were attached to strong magnets as opposed to being mounted in a fixed location. The second door was a mirror image of the first and required two linear actuators. One moves the bookcase door along with the slides, and one pivot around the hinges. Four 8” linear actuators were used to move both doors. These have sufficient force and speed in a compact size. Pinch free if a person or object is between the closing doors.Ī key component was the Progressive Automations PA-14 linear actuator.Emergency ingress/egress in case of power/Arduino failure.Lower the electric power use when in standby mode.Automatically close the doors if no motion is detected in the room for 2 hours.Include internal manual switches to open/close the doors.The external open switch should be hidden.Create a reliable fully automatic "open and close" mechanism for both door hinges/sliders.Phase 2 included adding the linear actuators to open and close the doors automatically. Phase 1 of the project included the building of the secret door. Our PA-14 linear actuator was the core component for this project. An open bookcase secret door defeats the whole purpose.The door was left open most of the time, exposing the hidden room behind the bookcases.To open, the bookcases slide apart slightly, and pivot inward into the ‘secret lair’, then sliding outward to not block too much space inside.įor more information on that part of the project, and to see the hinges for the secret bookcase door, visit the Instructables post.īruce McArdle’s reason for automating the hidden bookshelf doors was two-fold: The bookcases were handmade to support fully loaded shelves and have a unique hidden door mechanism (a hinge and slide), so the bookcases look like they are resting against the outside wall. There are three main components to this project, namely, an Arduino microcontroller, a motor controller, and linear actuators, which were used to enable the automatic opening and closing of a pair of doors (i.e., bookshelf secret doors). ![]()
