Left: a real serve reduced to its tracked skeleton, with the person and room removed. Right: a mount sized for the Zepp handle sensor, designed live by an AI through Andrii Shylenko's kernelCAD connector — drag to spin it. They're not the same object — one's a swing, one's a bracket — shown side by side so you can hold both at once.
MediaPipe Pose Landmarker tracked all 90 frames from the real serve, then drew only joints and bones on a solid field. The full portrait motion is preserved inside the compact frame; no person, room, HUD, or graph pixels remain. Measured Zepp orientation still drives the CAD at right and is not inferred from this skeleton.
Press play — this rotation is the real measured orientation of the Zepp handle sensor for this exact swing, frame by frame.
46 × 36 × 14 mm. The mount tumbles the way the sensor actually
tumbled during your serve — 797 frames pulled from the raw Zepp
capture (ztennis.db, swing 1767490069922), not a
decorative spin. The camera-angle slider only orbits your
viewpoint; it doesn't move the part.
Known caveat, carried over from the repo's own notes: which sensor axis maps to which physical handle direction is a documented best guess, not oracle-verified — the tumbling is real, the exact facing may be off by a fixed rotation.
Doesn't touch the part underneath — the shapes, the math, and the sharing links all check out exactly.
