Building a Mechanical Seven Segment Display

Introduction and Problem Statement00:00

The video introduces the concept of a seven-segment display. Unlike traditional displays reliant on power, the objective is to create a mechanical version that retains information without power.

Exploration of Existing Solutions01:22

The speaker discusses existing mechanical displays and their limitations, like manual input and complex control circuitry.

Designing the Mechanical Display03:00

An attempt to design a display using magnets and the concept of 'flip dots'. The speaker explains the use of electromagnets and mechanical design challenges.

Building the Flip Dot and Circuitry06:10

Detailed assembly of the flip dots, creation of custom PCBs, and solving wiring issues. The role of PCB manufacturing services is also highlighted.

Final Assembly and Testing09:15

After assembly, initial tests reveal wiring issues which are corrected using additional diodes. The display's functionality is confirmed.

Conclusion and Features11:30

The final display is demonstrated, showcasing its ability to be controlled via a hosted website. The ESP microcontroller enables different display modes.
