Matte-black hockey stick with a removable motion sensor in the butt end

Black Stick concept · Sensor online

The stick
is the controller.

Put one motion sensor inside the Black Stick. Every swing becomes a score, every practice becomes a challenge, and every young player gets a reason to go again.

01
Insert

A removable sensor plug sits under the butt-end cap, away from the stick's primary flex zone.

02
Swing

The motion sensor recognizes a shot pattern and sends the movement data to a nearby phone.

03
Compete

HockeyAI scores the round and places the player in an age-matched, parent-approved challenge.

Black Stick Core V0 · interactive assembly

Real parts.
Serviceable by design.

Rotate, zoom, explode, and inspect the removable butt-end module. The model uses recognizable XIAO nRF52840 Sense, ADXL375, protected LiPo, JST wiring, TPU isolation, and a rigid spine instead of generic placeholder blocks.

Build the honest version first

Motion is measured.
Puck outcome needs eyes.

A stick sensor can see how the stick moved. It cannot directly see where the puck landed. That distinction keeps competition fair and the product credible.
