Heavily inspired by a project from another member here: Huge Recessed Wall Mounted Tablet
Just finished my own DIY frame and tablet mount for home control. It’s making use of tasker, sharptools and kwgt to display key information on the home page. For layout, I am using Total launcher with flattered theme. In addition, TinyCam Pro for viewing my IP cameras, News widget, Google Keep widget for notes, and Fotoo app for screensaver.
For power supply, I am using existing 24V power supply that was available for my old wired home alarm system.
