Button Controller

A hand-wired 4×4 arcade button controller in a 3D-printed enclosure — built to automate the repetitive stuff so the keyboard can rest.

A dedicated hardware box built to solve a very specific problem: as a web developer, constantly typing out placeholder text is a grind. So instead of reaching for the keyboard again, why not build a physical button controller that does it for you? The result is a 4×4 grid of arcade-style buttons in green and red, housed in a 3D-printed enclosure, wired entirely by hand.

The inside is a proper handmade tangle of resistors, bent wire connections, and leads — the kind of internals that tell the real story of how it was built. Flip it over and it looks purposeful and clean. Every button mapped, every connection soldered. A silly idea that turned into a genuinely useful little tool sitting on the desk.
