Browser tool makes a Steam Controller crawl back toward its charger

Ray Foss has created Auto-Charge Tracker, a web tool designed to help Valve’s 2026 Steam Controller move itself back toward its charging Puck. It does this by combining camera tracking with the controller’s built-in vibration motors rather than using any dedicated drive hardware.

The setup runs in a browser: a camera is positioned above the controller, then the user marks the Puck, the controller’s front, and its rear in the camera view. From there, the page follows those points and triggers vibration patterns intended to nudge the controller across a flat surface.

The project builds on the redesigned Steam Controller’s charging options, which include USB-C and a charging Puck that also works as a wireless receiver. Foss also shared a demonstration on X showing the controller moving and lining up with the dock.

This is still more of a playful hardware hack than a reliable convenience feature. The source notes that the tracking points can be awkward to set, the tool is tuned for the 2026 Steam Controller, and a successful dock is not promised every time.
