Custom Smartwatch from Open-Source Design: Multi-Application Wifi and Bluetooth-Enabled Smartwatch Built from TTGO T-Display Development Board

Abstract

The purpose of this project was to build a custom smart watch from an open-source design. Through this project, I was able to construct an affordable and fully programmable and customizable smart watch with WiFi and Bluetooth capabilities. The watch utilizes a TTGO T Display development board with an ESP32 chip, a 3.7 V lithium polymer battery, an RTC module (real time clock), and a 3D-printed case. The watch is programmed in C++ and features several different "apps". These include the main watch face and a stopwatch (from original design), a Daily Checklist, a Weather Tracker (which pulls extensive and accurate weather data from an online API), a Terminal, and Network Settings. With continued development, I will add more "apps", and I have several in mind that I hope to begin development on when time allows. This project demonstrates an alternative solution to the desire for a smart watch, which 86 holds programmers and tech-enthusiasts in mind, and gives users the freedom to build and do whatever they want with their smart watch.
