Former NASA engineer created a car horn that can produce multiple sounds with DIY

One of the few ways in which a car can communicate with other cars is horn, but because there is only one tone, it is difficult to give variations to the content to convey. In order to overcome this situation, DIY produced a horn that allows former NASA engineers to produce multiple tones.

NICEST Car Horn Ever - DIY - YouTube


Mr. Rover, who was the former NASA engineer, who created this interesting horn. To many people, I often sounded horn to those who were walking smash hitting a car.


Even now even 1.3 million people are dead in a traffic accident a year. I hope the car gets a good voice, but only the horn or the turn signal is likely to be able. However, as horn usually sounds, it is only a noisy sound, so Rober's idea is to do something about this.


I used Adafruit's audio FX sound board ......


File of audio to sound


And metal switch.


Combine these to create a new switch.



It actually looks like this when you incorporate it in the instrument panel.



In a parking lot, I found a woman loading my baggage while opening the passenger's door. If you used to be a horn, you had to claim existence somewhat strongly in the horn, but one of the new horn has an electronic sound like when R2 - D2 talked.


A woman who was echoed with this electronic tone noticed that the car came as if it was "ohaya" and closed the door.


Meanwhile, I also encounter a child who keeps playing while crossing the front of the car. For such a time, a strong horn like a horn for a truck is also prepared.


It's a fairytale reaction, "What is it". It is a great success as a reminder.


In addition, it is said that this remodeling is possible for any car, commentary on a detailed installation process is done with another video.
