Device · AX-1.0

The board that measures itself.

AXIS is a skateboard deck with a pressure matrix and a 6-axis IMU laminated inside the plies. It streams every trick at 200 Hz.

Inside

The deck is the enclosure.

Every component is laminated between the plies. Nothing hangs under the board, so there is nothing to knock off on a ledge.

Only the IMU sits at the centre.

The 6-axis IMU is at the geometric centre of the deck, at mid-thickness. A kickflip turns the board about that line, so the sensor reads the spin itself and none of the swing around it.

The rest is spread out.

Where the feet are.

Put your own feet on the first card, then scroll through sample stances. The console computes the centre of pressure and the front and back split from each field.

Drag the feet. Press harder, or hold longer, for more heat. Only the lit grid is sensed. Position is yours; iIntensity is a model, not newtons.

Front foot: over the front bolts
Load: on the heel edge

Flight plan from the Gappin trick model: −360° about the long axis, nose tilted π/10 in the first 15 % of the flight. Next view: you fly it.

Kickflip · live

Your scroll is the clock.

YOUR ROLL RATE

0°/s

The mark is a real kickflip, about 1200 °/s. The IMU reads up to 2000.

ROLL 0° · AT THE IMU, r = 0, SO THE SPIN ADDS 0.00 g
