How to Build a Custom Circular LCD Wall Clock
A step-by-step guide for DIY enthusiasts to create a personalized digital clock.
1Project Inspiration
The difficulty of reading the oven display as the only time indicator in the kitchen sparked this customizable circular LCD wall clock idea. Using a 7-inch Waveshare display and Raspberry Pi, the project allows users to code their own clock face designs.
2Required Hardware
The project requires a 1080x1080 resolution 7-inch circular LCD, Raspberry Pi 3-5 series computer, microSD card, and suitable power supply. The screen's touch capability enables interactive clock face designs. Raspberry Pi 4 offers the best balance between performance and price.
3Setup Process
After installing Raspberry Pi OS, screen connections are made. The touch port handles both power and data transfer. A shelf solution avoids extra thickness for physical mounting. The VNC server enables remote control functionality.
4Brightness Control
The rear button cycles through 5 brightness levels. For night mode, Raspberry Pi 3 uses gammastep while newer models use Waveshare's Python script for automatic dimming. Software solutions simplify light adjustment.
5Custom Clock Faces
Full-screen browser displays various clock designs. Users can code details like Swiss railway clocks' minute pause, minimalist indicators, or fun designs. Touch gestures allow switching between different clock faces.
6Result and Flexibility
This project offers a fully customizable time display beyond standard clocks. Open-source solutions and touch interaction let users create and adapt digital clock designs to daily needs. A creative DIY home project that embodies maker spirit.
