This project started as a desire to have a modern digital clock that would use the natural light of the room for illumination. This means that the screen is always at a natural brightness, with it looking like paper rather than a traditional screen. By using an E-paper display, blue light is not emitted meaning that the clock does not disrupt your circadian rhythm before bed. It seamlessly updates every minute, and on the hour the screen does a full refresh.
Another useful function of the clock is that it uses a supercapacitor to ensure the time is kept even when it is unplugged for extended periods of time. This means the time does not have to be set again after blackouts like most other clocks.
