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.
