So he thought of experimenting with those, and built a ‘Binoctular’ LED clock which uses the Neopixel rings as 7 segment displays. Each digit is made using one pair of Neopixel rings, stacked ...

Evidently, [Nicolas Kruse] shares our affection for these displays, because he’s taken it beyond theory and created a 7-segment magnetically-actuated display from scratch. The display is 3D ...

The panels are arranged in a 7-segment display format, commonly used in digital clocks and calculators. Each digit is represented by seven segments that can be individually controlled to form numbers.

“I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano. The segments are controlled by 18 MAX7219 ICs which can control up to 64 individual LEDs or 8 ...
