Bling Your Server Rack: A Nostalgic Retro Project with 128 LEDs
2025-01-15
Driven by nostalgia for the blinking lights of old mainframes, the author designed a project to add 128 LEDs to a server rack. Using readily available and inexpensive PIC16F1782 microcontrollers and 74HC595 shift registers, the project uses serial communication to control the LEDs, allowing for custom displays and a random pattern mode. The author shares the PCB design files and C code, encouraging others to build their own or contact him for custom orders. This project is a fun blend of practicality and nostalgia, showcasing the author's electronics and programming skills.
