The clock’s electronics rely on an Arduino. The issue with an Arduino, of course, is that the time base isn’t always good enough to keep time over long periods.

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino… ...

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...

Arduino enthusiasts, makers and hobbyists looking for inspiration for their next project might be interested in a unique Arduino clock aptly named the Time Slider.
