Adam Renie shared this on the Adafruit Forums: “I purchased the A’SYCK AD-121F2 from Adafruit last year and finally posted a little review and demonstration of it in action on my blog. It’s a really fun display, I may just have to purchase 3-5 more to make a more easily readable and colorful clock!”
From his blog:
I wrote a quick sketch to read the current time from the Maxim DS3231 on the Chronodot, and to cycle the display through hours, minutes, and seconds. The first digit of the hours fades in from black to red, then the second digit fades in as green and out to black. The first digit of the minutes fades in from black to green, then the second digit fades in as blue and out to black. And finally, the first digit of the seconds fades in from black to blue, and then the second digit fades in as red and out to black.
The display is nice and bright bright. I had to shoot this video through several pieces of tinted acrylic to stop my iPhone from adjusting the exposure. I didn’t realize this until I uploaded the video, but there is a bug in my code when accessing the DS3231 registers right as the minutes increment. But you get the idea, right?
