Timesquare DIY Watch Kit

The Timesquare DIY Watch Kit is a build it yourself LED watch that is compatible with Arduino so can be reprogrammed and customised however you wish. It comes in 5 colours red, white, green, blue and orange, and you can make your own 3D printed faces like the one in the picture below.
Kit Price - $29.95

64 LEDs light up to tell you the time in a variety of ways. Built into the kit are 3 different watch 'faces' - a scrolling marquee with time and date, a binary watch display, and a moon phase display. There's also a built-in battery meter so you can check your battery life.
This is a DIY kit, and requires some basic soldering/assembly to put together. It is a beginner kit, so this is a fine project to use in learning how to solder.
