**Ploopy Classic 2: A Faster, More Open Trackball for Tinkerers**
Ploopy’s latest open-source trackball, the *Classic 2*, upgrades its predecessor with a Raspberry Pi RP2040 microcontroller for 15x faster scrolling, USB-C connectivity, and a 3D-printable design that skips support structures. Retaining the PMW-3360 sensor and D2LS-21 switches, the DIY kit ($101) and pre-built model ($147) stay true to Ploopy’s hacker-friendly ethos—with full schematics on GitHub for customization.
