I have bought a tiny OLED display, its clean and clarity draw my attention. But what can it do for? How can I show it off? The second one is the point. (hahaha)Well, when I looked at the poster, its The Lord of the Rings, which is my favorite movie series.
Then, I got the idea! How about use this OLED display to make a ring clock? Well, I need to prepare the power supply, clock module and main control.
According to the thickness of the wrist and fingers, cutting the elastic braid tape and stitch the opening area with a needle line.
Using hot melt gun to stick previously welded parts to the telescopic ring.
And then this scuffed ring clock is done.
