Bekant-Desk
I hooked up the GPIO pins of a Raspberry Pi to the controller of an IKEA Bekant desk, allowing me to alter the height of the motorised desk using a web UI.
The whole system relies on WiringPi to change the state of GPIO pins soldered to the physical buttons of the controller that came out of the box. It's a simple bash script that alters the state of the controller, making the desk move. These scripts are triggered by the buttons on a webpage.
