This DIY watch works but for only a limited amount of time
December 5th, 2020—
The Nano is one of our smallest boards, and as YouTuber Craft Channel has proven, it’s tiny enough to act as the brains of a wristwatch. This DIY wearable device features a nicely made wooden enclosure, with power supplied by a 1S 300mAh LiPo battery, and the face itself shown on a 1.3″ ST7789 display.
Its lack of a real-time clock unit, along with a fairly limited battery, means that the watch will only work for a short time before needing attention. However, creator Craft Channel notes that the build is an experimental project, and it’s a great demo of what can be done with a short bill of materials and a bit of ingenuity!
