SEVEN-SEGMENT SINGLE-STEPS THROUGH THE TIME

Have you ever looked at the time, and then had to look again because it just didn’t register? This phenomenon seems more prevalent with phone timepieces, but it’s been known to happen with standard wall clocks, too. This latest offering in a stream of unusual clocks fashioned by [mircemk] solves that problem by forcing the viewer to pay attention as the time flashes by in a series of single digits, separated by a hyphen.

Inside the boxy blue base is an Arduino Nano, a DS3231 real-time clock module, and a perfboard full of transistors for switching the LED strips inside the segments. There’s an LED on the front that blinks the seconds, and honestly, we’re kind of on the fence about this part. It would be nice if it faded in and out, or was otherwise a little less distracting, but it did grow on us as we watched the demo.

We love the way this clock celebrates the seven-segment display, and only wish it were much bigger. The STLs and code are available if you want to make one, though they only cover the 7-segment part — the base is made of foam board. Check out the demo and build video after the break.

Would you rather hear the time go by in gentle chimes? Here’s chime clock that uses old hard drive actuators.
