Make the World a Better Place : Polite Passing and Safer Bicycling – the courteous talking bike helmet with turn signals
My wife asked if I was really going out in public with the helmet....... I did.
Then she asked if I really rode a bike in public with this helmet.......... I did.
She thinks I've totally lost my mind and have no shame.
The short video including field trials
The Polite Passing talking bicycle helmet helps improve traffic safety and promote proper greenway etiquette. People enjoy nature better and safer with polite & consistent greenway audio communication.
- While bicycling, repeating “passing on your left”grows weary after awhile, especially getting frustrated with road hogs, inattentive pedestrians, runners and bikers on the phone or listening to music.
- Bicycles are pretty quiet and can be fast. They surprise distracted people enjoying the outdoors and nature. Lets keep them safe.
- LED turn signal flashers on the rear give warning to other traffic approaching you from behind.
Version 1 – Arduino Nano control. DFPlayer audio + 3W amp + speaker, activated manually with small pushbuttons mounted in helmet.
Why version 1 ? If time permits there could be a version 2 and a version 3, .....incorporating a Nicla Sense ME using gyro signals for activation rather than pushbuttons.
