Touching your face is a subconscious behavior that we all do, and it is also an easy way to pick up illnesses like the coronavirus and flu. However, like many infectious diseases, proper hygiene can help reduce your risk. With this in mind, Nick Bild designed a simple solution in the form of a modified pair of glasses to provide a subtle reminder not to go near your eyes, mouth, and nose.

The project, which Bild calls Sentinel, consists of an ultrasonic sensor mounted on top of the bridge and an Arduino Nano along the temple. Whenever a hand (or object) is detected in close proximity to the face, a red warning LED lights up in the wearer’s peripheral vision.

When you get a notification on your smartphone, more often than not, you’re doing something more pressing. You then silence the alarm, and perhaps forget about it. Nick Bild, however, has created a pair of smart glasses that take a new “look” at things by instead giving you a notification when you’re staring at an appropriate item.

For instance, as demonstrated in the demo below, if your calendar says to “Go for a walk,” the Newrons would light up when you’re glancing at a pair of sneakers.

The prototype is controlled by an Arduino Nano 33 IoT, which connects to the Google Calendar API over WiFi to view your schedule. Object recognition is taken care of with a JeVois A33 machine vision camera and notifications are shown on an LED.

Jordan Fung is a 13-year-old maker and programmer based in Hong Kong. He recently developed Arduino-based smart glasses called Pedosa Glass, which are able to activate, in this first release, a flashlight and a timer:

The Pedosa Glass is powered by a single Arduino Nano running an “operating system” developed by me.
There is a tiny FLCOS display in the front. The AV signal from the Arduino will be displayed on it. It is equipped with 3 push buttons, in which 2 of them are control buttons and one of them be the home button, also equipped with a super-bright white LED for use as a flashlight.

In the picture below you can explore the electronic scheme:

Jordan is working hard to add new applications and features to the project but in the meanwhile he shared his work on a great tutorial on Instructables.
