With Timothy Giles’ rotating digital picture frame, you’ll never have to endure black bars around your vertical images again!
Rather than accept the poor presentation of vertical images that normal displays offer, Giles instead made his own out of a discarded 27-inch LCD TV. A Raspberry Pi displays the images sideways, then uses an Arduino with a stepper shield to rotate the TV to compensate.
Mechanically, he uses a herringbone gear set to turn the TV, while the Arduino accelerates and decelerates the TV’s rotation to give a smooth transition. It’s a very cool project, and one that makes you wonder “why didn’t I think of that?”
