I’ve had an Adafruit NeoTrellis M4 Express for a while and it’s a lot of fun to play with. It’s got NeoPixel illuminated buttons, audio capabilities, a powerful SAMD51 CPU, and a lot of potential.
I’m on the Apps Infrastructure team at Automattic, so I thought it would be cool if I could make it represent the states of our Buildkite builds on the board. Green would mean the build passed, red would mean failed, pulsating yellow if running, etc. Pressing the button would open the build directly in my browser.

So that’s exactly what was built! Thanks to AI tooling I was also able to add some goodies like simulators for the Trellis as well as incoming Buildkite data.
Builds can be filtered in a menu bar app by queue or pipeline, as well as states (e.g. just show me failing builds).
