Radar Glasses Using Small Vibration Motor For Blind Navigation

Engineer”tpsully” became inquisitive about navigating his environment while blind following his buddy lost sight in his right eye and meeting with others that have blindness. When there are Braille messages onto several buildings, seeing-eye puppies, walking canes, as well as audible alarms at crosswalks, he believed what he could assemble to further help the blind navigate, also came up with what he calls Radar Glasses.

In fact, tpsully enlarged on a previous design for an apparatus he made for his buddy, but uses the majority of the exact same technologies — such as an ST VL53L1X TOF (Time of Flight) sensor and an small Vibration Motor. The eyeglasses use the techniques to make unique degrees of vibration based on the space of these items — the closer an individual gets, the longer the engine vibrates, permitting the wearer to browse around them.

The Radar Glasses layout includes 3D-printed frames using an Adafruit Perma-Proto breadboard cut and elegant to match the framework attachment and outline points. The engineer then puts and wired the detector, Trinket M0 microcontroller, along with other elements (resistors, tactile change button, etc.) and a 3.7V/150mAh LiPo battery for electricity.

Tpsully says his eyeglasses function well for being a model but add you might choose to place some rubber or alternative jelly-like substance on the shirt which rolls out the bridge, as appearing down has an inclination to elevate the eyeglasses of their nose, decreasing the vibration which may be sensed.

For individuals wanting to replicate this particular set of Radar Glasses, head to the job webpage for all of the essential documents, BOM, and also a full build walkthrough.
