From the production schematic, with the buttons on their 30 mm grid as on the board. Holding a button lights its LED here so you can see both paths. That part’s only an illustration, since there’s no firmware in this repository.

Assets

Logo, colors, and type.

Mark

The project’s generated logo mark. The grid gets finer with the commit count, and the cells show the split between languages. It’s redrawn as the project grows.

Palette

The colors Button Box uses across this site: one hue from its discipline’s band, plus the shades that make it work on both dark and light backgrounds.

Button Box Embedded & hardware DM SANS · NEWSREADER · DM MONO

Type

The two typefaces on the site: a sans-serif for the interface and a serif for headlines.
