Here’s one for the minimalists: a progress bar for your day. It’s a simple, intuitive display that displays a line of light that grows from left to right as the working day inches by. And because it’s connected to the internet via a Raspberry Pi Pico W and the magic of MicroPython, it can grab data from your Google Calendar and display when your day’s events are. Other than the Pico W, the components are simple: just a strip of RGB LEDs, a frame to hold them (angled aluminium from your local DIY shop would work), plus a strip of opaque plastic to work as a diffuser.
