Word clocks are pretty popular “artsy” ways of telling time, but [doktorinjh] wanted to try something a little different. So instead of showing the time — it shows the weather.
He’s using an Arduino Yun to access the Weather Underground API for data and then sends the data out to a grid of 100 individually addressable RGB LEDs — NeoPixels to be precise. The LEDs are overlayed with a laser cut acrylic sheet with various words and weather icons to allow for a pretty specific depiction of current (or future) weather conditions.
The frame is made out of colonial style molding and since it’s a weather clock, he turned the grid of LEDs into a rainbow effect, because, why not?
He’s got more photos and a build log in his photo album, which you could use to create your own.
