Hacker Permanently Solves Nintendo Switch Joy-Con Drift With a Touchpad Upgrade - Gizmodo

Pisani hadn’t actually experienced the Joy-Con drift problem with his Switch yet, but he figured this hack—which he’s exhaustively detailed in a Medium post—would ensure it was a problem he’d never encounter if he managed to pull it off.

Starting with a transparent green Joy-Con housing (an unnecessary upgrade but one that certainly adds some retro charm for those who owned the lime green Donkey Kong 64-themed N64) he transplanted the guts of his Switch’s left Joy-Con while removing the joystick components in the process.

The electronics were upgraded with a digital potentiometer, a capacitive touchpad wrapped in a custom 3D-printed enclosure, and an Arduino Pro Mini (among other bits) which is used to translate the digital signals from the touchpad to analog joystick signals the Switch is expecting.
