The Monochron is an extremely rewarding kit to build. Not only is it fun, but the finished clock adds retro flair to any home. As with all Adafruit kits, the instructions are clear and well thought out. The clock features an alarm function, custom laser-cut case, and several different display modes to suit your mood or decor. It’s completely open source, and free-download variations of the software display the time using a simple modern font, Dali-esque animations, or retro arcade numerals. Feeling more adventurous? Program your own custom clock functions and fonts. Just don’t forget to share your code!
