Underwater Sound Beacons for Visually Impaired Swimmers

Hackster.io user Bob Hammell created these sound beacons based on conversations with “individuals who experience visual impairment firsthand, to help identify the unique needs of swimmers with disabilities.” The beacons include our RP2040 Feather, Bone Conductor Transducer, a 3D printed enclosure and more:

Key features of the beacons include:

1. Directional Audio: Beacons are designed to project their audio directly upwards when placed underwater, allowing swimmers to hear the sound as they swim above them and assess their proximity to the beacons.

2. Easy Deployment: Beacons are easily positioned in the pool using anchor weights and can be easily removed, offering a solution that does not require any permanent changes to the pool facility.

3. Customized Cues: Each beacon can be individually configured to emit a unique audio cue, such as a voice distance notification (i.e. “3 meters”), providing swimmers with direct information about the beacon’s position.

This combination of features results in an innovative hardware device that can solve the navigation and safety issues faced by swimmers with limited vision.
