E-Paper Weather Display

Someone in my dorm made an e-paper weather display using a Raspberry Pi and a small e-ink screen. It sits in the hallway showing the temperature, conditions, and a 3-day forecast in a clean black-and-white layout that updates every 30 minutes. The e-ink screen uses no power between updates, so the whole thing runs on a USB cable drawing less electricity than a night light. Weather is displayed the way a newspaper would show it, with large numbers and simple icons. The lack of color or animation makes it feel permanent and reliable rather than digital. I walk past it every morning and glance at the temperature. Reading it takes about 1 second, and that's the design achievement. A phone weather app gives you the same information, but you have to unlock the phone, find the app, and wait for it to load. That adds enough friction that I often just look out the window instead.
