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.

(OMG!!!)
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.

1. 0.91Ć¢128x32 I2C OLED Display x1
2. 3.7V Lithium Battery Charger x1
3. DS3231M MEMS Precise RTC x1
5. 1000mah 3.7v Lithium Battery x1
6. Needle x1
7. A piece of elastic braid tape


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.
