Display Glasses and Smart Watch
Display Glasses and T-Watch 2020
2019/2020
These projects were spaced out relatively far apart, and I am even still working on the smart watch on and off. The display glasses were originally meant to display significant data (i.e. temperature, voltage, etc.) on them while working in the shop in order to increase efficiency. This changed later on when I found out about this custom programmable smart watch from Lilygo. This watch is based upon an ESP32 microcontroller which gave me a lot more freedom to connect to things and send data from my watch to my glasses.
The display for the glasses is a transparent OLED display, which I got from Sparkfun. I originally connected to it via an Arduino Nano and wrote my own code to get the characters vertical (I believe there is a function to rotate text but it didn't work as I wanted it to). In the photos above you can see a screen test from when I got this vertical text to work, and I am still working on getting the T-watch connected.

The main code for the smart watch I got from wfdudley on Github and I then went through it and customized it to fit my needs. I added a couple apps, one for a TV-B-Gone Remote (as the watch has a built in IR Transmitter) which I covered thoroughly in one of my Instructables. The other was an app to connect to an ESP-01 device to send data to, which In plan to use for said glasses. I got the majority of that code on SWA here, but just edited it into an extra app.
