Automated Secret Library Door using Linear Actuators
This is an amazing Secret Door project that uses a Firgelli linear actuator and an Arduino to open and close a secret door either by pulling on a book or using a secret knock!
Basically the bookcase slides into a false wall that was built to create a hidden space in an attic. The linear actuator pushes and pulls the bookcase in and out and is activated by the Arduino. A microswitch was wired to the Arduino that tells the actuator to open or close when the secret book is pulled. The Arduino was also programmed with a secret knock detection algorithm so that the door can be opened with a secret knock. Take a look at this video to see the door in action.
Firgelli Automations is one of the original linear actuator and TV Lift manufacturers. Since 2004 we have been developing our own line of Linear Actuators, Track actuators, TV Lifts, Desk Lifts, and many other Motion control products to support many different industries.
Our products have been used in just about every application you can imagine from home automation to space exploration. Firgelli Automations is on the leading edge of Linear Actuator research and development, searching for innovative solutions to linear motion control.
WE SHOW YOU STEP BY STEP - Exactly How to make a Drop Down TV lift in under an Hour and for under $400. We used a standard kitchen cabinet that is above a sink and converted it to a drop down TV lift so that when you clean the dishes you can also watch TV. When your done simply press the button and the TV will raise out of the way. All parts can be purchased from www.FirgelliAuto.com and they will sell the entire package as a kit for you. The kit is scale-able too, to be able to use larger TV...
