What happened
Ploopy has announced the A+, an upgraded version of its open-source, 3D-printable Adept trackball. The A+ adds two buttons (now eight total, two of which are knobs for scrolling), a detachable wrist rest, and QMK-based gestures, layers, and on-device configuration. Preorders for the kit open August 19, 2026 at 10am ET for $99 CAD.
Why it matters
If you use a trackball for RSI reasons or build QMK-based input devices, the A+ adds knobs and gesture support that may justify an upgrade or a first purchase. For everyone else, this is a niche open-source hardware release with no direct impact on your work.
Discussion angle
Whether open-source 3D-printable input devices like this are a viable alternative to commercial ergo hardware for developers dealing with wrist strain.
