A Pimoroni Stellar Unicorn showing calendar free/busy status. Sits on the desk. Glows red or green depending on whether you should be interrupted. People knock before entering now. This is the entire point.
The Stellar Unicorn is the compact square variant of Pimoroni’s Unicorn family — 256 RGB LEDs in a 16×16 grid, 108×108mm, RP2350 on board. Same family as the Galactic but a more practical desk footprint for something that just needs to communicate a status at a glance. Speaker on board, buttons, battery connector, stands on its own metal legs.
Not e-ink. RGB LEDs. Glows. You will see it.
Connects to the calendar and shows whether you’re free, busy, or in something that should not be interrupted. Web interface running on the Pico for manual override when the calendar lies (and it does). Simple premise, very effective in practice.
Working baseline is running on the device. Code is on the Pico and needs extracting and committing before anything changes — first rule of embedded projects: get the working version into version control before you touch it.
After that: case redesign in Solidworks (current one is functional, not pretty), reprint, and a pass over the web interface.
Pimoroni Stellar Unicorn (Pico 2 W Aboard), MicroPython. 16×16 RGB LED matrix. Web interface for manual status control served from the Pico itself. Calendar integration for automatic updates. Case designed in Solidworks.
