Computer programmer creates voice-activated face mask with moving LED mouth


A computer programmer designed a face mask that relies on a microcomputer to power a variety of LEDs to show a moving mouth while the wearer speaks.

The idea is that the face mask can actually tell you when the wearer is speaking, and it can also be controlled with a tongue click to display an illuminated smile.

This invention is the brainchild of game designer and computer programmer Tyler Glaiel, who created the LED panel that fits comfortably into a fabric mask after coming up with the idea some time ago.

In an interview with BBC News, Glaiel explained, “I had a random idea for this.

“I was wondering if there was, to have a face mask that just lit up with mouth shapes so I looked online to see if there was anything I could buy to do that and there was really nothing there. “

Spotting the gap in the market, he got to work.

Plus, he even shared the process the way he did, but you’ll need a decent level of electronics know-how if you’re going to make your own version at home.

It is based on an Arduino Nano, which is a popular programmable microcomputer similar to a Raspberry Pi.

The Arduino controls the LED lights and the mask’s voice recognition system, and all of the work is powered by a nine-volt battery.

He spent about a month experimenting with his creation before settling on the design that we can see in front of us.

The electrical part of the device can be completely removed so that it can be sterilized, and so that the fabric mask can be washed.

However, it should be borne in mind that the mask gets quite warm and it is not the proper PPE standard, so it is best not to be worn by children or those who work in hospitals. , and not too long.

That said, it’s a nice variation on the impersonal masks most people wear these days. It’ll make someone laugh on the bus, that’s for sure.

To build it you need a few basic components such as an LED matrix, a small microphone, wire, converter, resistors and capacitors.

Oh, and you’ll have to buy the Arduino as well.

It’s not an exhaustive list, but if you want to make it, it’s all there on the blog.

In total, the cost will be around $ 50 (£ 40).

He made the information open source by sharing it in a blog post, but you will have to make your own, as Glaiel said: “I have no intention of selling them.”

The code to program the device is also available on GitHub, although you may need additional coding knowledge depending on the exact components you are using.
