Google rarely enters the hardware world and when they do, they receive a mixed reception. The smart glasses were very controversial when they first launched, due to privacy and fashion concerns. But the idea was a good one: a wearable computer that gave you a heads-up display (HUD) at all times. Unfortunately, even today’s Google Glass models are very expensive. That’s why this Redditor built their own DIY smart glasses using affordable components.

The pair looks a lot like a bulkier version of Google Glass and they perform a similar function. The wearer gets a HUD positioned in front of one eye that displays useful information. In this case, the information comes from a separate device via Bluetooth. The software is still in development, but these glasses could theoretically display any information from a connected smartphone, such as navigation or text messages. The screen is monochrome and has a low resolution, but it is enough for basic graphics and text.

The primary component is an Arduino Nano 33 BLE. That drives a 0.49″ OLED screen through an I2C connection. A lens and mirror project the screen onto a clear phone case lined with HUD film intended for cars. Power comes from a small 450mAh lithium-ion battery. The frame is off-the-shelf, but the enclosure for the electronics is a custom 3D-printed affair. It allows for adjustability, making the screen clear and readable. The software isn’t ready yet, but the STL files are available if you want to build your own DIY smart glasses.

The post Giving Google Glass a run for its money appeared first on Arduino Blog.

For his school science fair, Mars Kapadia decided to take things up a notch and create his own pair of smart glasses.

The wearable device, which went on to place in the state competition, uses a transparent OLED display to show info from Retro Watch software running on an Android phone. They’re controlled by an Arduino Nano Every with an HC-05 Bluetooth module to communicate with the mobile app. Power is provided via a LiPo battery.

One unusual feature is that the darkened lenses can be flipped down for sun protection in outdoor environments, then up to allow easy viewing in darker areas. Kapadia demonstrates how his glasses work, plus discusses the technology used in the video below.

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.
