Introducing the latest clock from WoodUino – The Two-Four Timepiece 24 hour analogue clock. The Two-Four Timepiece shows a complete day at a time, and marks out time with an hour hand, minute circles and a gently pulsing seconds marker. Sunrise and sunset times are displayed and the display’s colour scheme changes between daytime and nighttime.
The Two-Four Timepiece display is built using a total of 89 addressable LEDs arranged in strips that radiate from a central point. The strips are adhered to a perforated PCB substrate cut into a squared-base circle shape. The LED strip is controlled by a discrete Arduino UNO and a battery-backed up real-time clock that keeps accurate local time. Sunrise and sunset times are determined using the user’s location (longitude and latitude) and GMT offset (using the DST algorithms previously described) using the sundata.h library, as used in the Graphic LCD Analogue Clock and SolarTracer.
