A person who created a 'flip disk display' that rotates a disk painted black and white on both sides to project images appears

Flip-disk displays, which use a disk painted white on one side and black on the other to display images, are often used in baseball scoreboards and highway signs. Someone has created their own flip-disk using an NVIDIA kit.

A flip disk is a type of display that uses electromagnetic pulses to rotate a small disk and display images in two colors, black and white. Flip disk technology itself has been around since the mid-20th century, and even after organic electroluminescence (EL) and liquid crystal displays became widely used in the 21st century, they are still used outdoors where strong sunlight can make it difficult to see.

The flip disk was created by Google product manager Cathy Koreveck . You can see how the flip disk works in the video below.

At first glance, the display appears to project images using light.

In fact, it is represented by a large number of disks.

There are a total of 3528 discs, arranged 42 vertically and 84 horizontally.

The image is projected using a microcontroller and NVIDIA's

Orin Nano . It is also possible to connect a speaker to play sound, or to display an image based on the image from the camera.

The JavaScript library for operation is available on GitHub etc.

'I wanted to design a large piece of wall art for an office, but I didn't like the LED glow of a traditional screen,' said Korevek. 'The Flip Disc is an interesting option. It has good readability, a long lifespan, and achieves 25-60 fps. Plus, it has the added bonus of making a sound like rain hitting a window every time the disc flips.'
