Here comes the Git Contributions E-Ink Display, an ingenious creation by a DIY artist that is designed to show your GitHub graph. Now, those who are regular with GitHub and are privy to the way it works should be familiar with its graphical calendar display of activity in the form of a grid. As Hackaday stated, it might seem like a hive of activity for many, though many may find it spotty.
However, if you feel like showing off your graph to the world, something that should come quite naturally to anyone who is proud of his or her graph, the Git Contributions E-Ink Display can be the perfect way to do that. It might not be something that anyone would connect with right away. Rather, it has an air of exclusivity to it, and it is this that adds to its appeal all the more.
As is evident from the image, the Git Contributions E-Ink Display comes across as a device that is quite small. The outer casing has a wooden finish to it and lends a classy touch to the device. The case, though, is not made of real wood but has been 3D printed. The E Ink display offers a monochrome rendering of your current GitHub graph and seems quite adept at doing so. The black and gray dots against a stark white background look nice, it must be said.
Behind the scenes, it is the familiar ESP32 microcontroller that is pulling the shots, along with an all-in-one board, with the display serving as the frontend. Keeping things moving is a Li-Po battery of unknown specification, though given the extremely frugal nature of e-paper displays, expect the battery to last weeks or maybe even months on a single charge.
