Create your individual inexpensive Arduino-powered good glasses

When Google Glass launched in 2013, the general public opinion gave the impression to be “fascinating expertise, however the world isn’t prepared but.” Now that greater than a decade has handed, the world might lastly be prepared — particularly with the omission of controversial options like video recording. If that appeals to you, then Akashv44 has an excellent tutorial that may stroll you thru constructing your individual inexpensive Arduino-based good glasses.

The largest problem for a venture like that is the geometry of the heads-up show optics. Our eyes can not give attention to a display screen that’s too shut. The display screen must be a minimum of a couple of inches away to comfortably learn. However these few inches don’t have to be in a straight line, so this machine makes use of a mirror, a lens, and a bit of glass to venture display screen content material in entrance of the person’s eye. The whole distance alongside that path is sufficient for the person to give attention to the content material with out eye pressure.

That content material comes from a small monochrome OLED display screen chosen for its excessive distinction. The darkish pixels of the display screen are primarily invisible, whereas the lit pixels are straightforward to see. The content material on that display screen comes from an Arduino Nano board. It receives energy from a 300mAh lithium battery (this design doesn’t comprise a charging circuit) and an HC-05 Bluetooth module lets the Arduino talk with exterior units.

In concept, the Arduino can show any alphanumeric digits that it receives by way of Bluetooth. So, the content material proven will rely on the person and there are numerous prospects. It might, for instance, reveal incoming textual content messages or details about no matter music is taking part in.
