TL;DR
Gokux has created a modern take on the traditional film clapperboard by developing the E-Slate, a digital clapperboard featuring a large 7.5-inch E Ink display. This device addresses the common issues of legibility and smudging that come with conventional clapperboards, especially in bright outdoor settings. With the E-Slate, filmmakers can easily update key production details such as roll, scene, take, director, and date using a companion smartphone app, which connects to the device's built-in Wi-Fi.
