I wanted a clock that never needed setting. Things escalated.
Summary
A person wanted a simple bedside clock that sets itself automatically and shows time on a red seven-segment LED display. Since they couldn't find one that met all their needs, they decided to build their own clock using a Raspberry Pi, a seven-segment display from Adafruit, and 3D printing.Key Facts
- The person wanted a clock with automatic time setting and daylight saving time adjustment.
- They preferred a red seven-segment LED display, which is rare in self-setting clocks.
- They chose to use a Raspberry Pi Zero W for its Wi-Fi and ability to get accurate time via a network service called NTP.
- The clock display used was from Adafruit, which includes the LED display and a control board.
- The builder had to learn how to solder to connect the display parts.
- They used 3D printing to create the clock’s case.
- The project files, including parts list, software, and 3D printing designs, are shared publicly.
- They avoided using apps that could invade privacy by relying on the Pi’s built-in open-source software.
