Ploopy Bean: a trackpoint for every computer

· open-source · Source ↗

TLDR

  • Open-source, QMK/VIA-powered pointing stick at $69.99 CAD, fully assembled, currently in tiered preorder with launch date 6 May 2026.

Key Takeaways

  • Uses four Omron D2LS-21 buttons; runs QMK with VIA support for on-device remapping without reflashing.
  • 3D-printed enclosure (PLA, black); PCB, spring, magnet, and friction nub included; ships fully assembled.
  • Preorder tiers: Early Access ships immediately, Tier A within 8 weeks, Tier B within 20 weeks of launch.
  • Warranty is voided by any firmware or hardware modification, which conflicts directly with the open-source/QMK modding pitch.
  • STL files and a Modder’s Guide are available; QMK Toolbox and QMK Configurator supported for custom firmware.

Hacker News Comment Review

  • Core criticism: a standalone pointing stick divorced from a keyboard defeats the ergonomic premise of trackpoints, which exist to keep fingers on home row.
  • The mechanism differs fundamentally from IBM-style trackpoints: this uses a 3D Hall effect sensor and a physical spring, so travel and feel may resemble a gamepad thumbstick more than a classic trackpoint.
  • Print quality in demo photos drew scrutiny, with commenters attributing visible surface defects to under-extrusion rather than bed adhesion issues.

Notable Comments

  • @chrchr: Flags the Hall effect + spring mechanism vs. strain-gauge trackpoints; real-world feel is an open question.
  • @dsr_: Notes X11/libinput scroll-lock button mapping as a workaround for the missing dedicated scroll button.
