Check out how to create a unique Mechanical 7 Segment Display using cardboard! In this video, we unveil a one-of-a-kind mechanism that we've invented, featuring 7 circles each with its own trigger.

Each segment contains a small neodymium magnet, and each coil a 1 mm iron core for flux concentration. The coils are driven with a 1.6 A peak current, causing the segments to flip in less than 10 ms.

The key consists of the Account String and the Object Code. Each segment captures a different element.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

There are plenty of conventional timepieces out there in the world; we’ve also featured a great many that are aesthetically beautiful while being unreadably esoteric. This neat “shadow … ...
