ClockTHREEjr is an awesome platform for anyone wanting to explore time with electronics. The ClockTHREEjr is a smaller version of our earlier, wildly successful, Kickstarter project ClockTHREE. ClockTHREEjr fits perfectly in a 9" by 9"IKEA RIBBA frame (not included, sold separately). It features mono-color LEDs in a 16 column by 8 row matrix, giving it a total of 128 addressable LEDs. ClockTHREEjr is sold assembled with an English faceplate. This is not a kit, but a fully functioning clock ready to hang on your wall. To support use in all countries, ClockTHREEjr is powered by USB. Please use an old cell phone charger or empty USB port on your computer to power your clock. If you would like a clock in, German, French, Hungarian, Hebrew, or Dutch, you can buy a Faceplate/chip upgrade from Wyolum. Or if you would like a clock in a different language, please contact us, we'd be happy to work with you to develop it with you. Also available as a kit.
