Steady Aim Trainer

Practice holding your bow as steady as possible over a configured time window.

Hold Duration

Disconnected

Connect a sensor or start demo mode to train.

🎯

Ready to Begin

Set your hold duration and click Start. Make sure your bow sensor is connected and calibrated.

Bow Shop

Customize the 3D bow model used across the dashboard and alignment views.

Bow Materials

Uses named Blender materials from the compound bow model. Sights and electronics stay separate for future attachment controls.

Power Management

Wake-up Sensitivity - 2.0 g

Acceleration threshold needed to wake the chip from deep sleep.

Sleep Timeout - 300 s

Idle duration before sleep when disconnected.

Sleep Sensitivity - 0.15 g

Movement threshold to keep device awake while idle.

Enable Device Auto-Sleep

If disabled, the device remains awake indefinitely until powered off.

Telemetry & Buffer

Release Threshold - 12.0 g

Impulse threshold for bow release detection, set in BLE firmware.

Follow-Through - 1.5 s

Post-release recording delay before freezing trace.

Trace Buffer Rate - Device 52 Hz / Web 208 Hz

Same capture setting for firmware recovery and browser shot review; the browser stores a higher-rate local trace.

Live Stream Rate - 1110 Hz (Max)

Telemetry frame transmission rate over BLE.

Persist Traces Offline (RRAM)

Saves traces to non-volatile flash so they survive deep sleep power down.

Sensor & 3D Alignment

Drag the preview to orbit. Two independent things live here: where the sensor sits (changes the data the firmware reports) and how the 3D bow looks (display only). Adjust each in its own section below.

Sensor Mount changes data

Where the XIAO board is physically mounted. This sets which IMU axis points up, forward, and sideways so cant, pitch, and yaw read correctly. Pick the matching preset, then rebuild firmware with the same axis mapping.

XIAO position on bow

Preview the selected board mounting direction before updating firmware axis mapping.

Fine-tune the mount in 90° steps

Resulting firmware axis mapping

Bow X IMU X Bow Y -IMU Z Bow Z IMU Y

Firmware-computed BLE/serial angles need the same mount mapping compiled into the device.

Preview only these just move the 3D view above — they do not change data or firmware.

3D Model Display display only

Adjust only the on-screen bow model. Use this when the sensor data is right but the model leans, rolls, or pitches the wrong way. This never changes saved data.

Data Backup & Restore

Export every locally stored shot, trace, session, and bow profile to a single JSON file, or import one back. Fully local — no account needed. Useful for moving field-test data between devices or keeping a backup.
