Micro WordClocks
LED matrixAn older creation, measuring only about an inch square and using a single 8x8 dot matrix LED as a display. The mask is simply inkjet printed onto paper and glued to the front. Driven by an Arduino, DS3213 RTC, and MAX7819 dot matrix LED driver.

Really? A video? Like watching paint dry. Or clock hands move. Look: the quarter doesn't change. More here. |
OLED display A new one. A crisp 1-inch OLED display married with a small form factor ESP8266 (the WeMos Mini, rapidly becoming my favorite.) WiFi enabled, this clock synchronizes with an internet time server, and displays the Word of the Day as a bonus. Kudos to Daniel Eichorn for concept and display driver. Oh, I also threw in a temperature and humidity sensor because, well, I could.

This video shows the nice animated effect between frames after power is first applied and a WiFI connection made. Two clock modes, temperature and Word of the Day. Adapted from my larger Word of the Day Clock. (The flickering is a camera artifact, and not visible when viewing directly.) |
