The author embarked on a hobby project to add visual appeal to a boring rack server by creating LED panels using cheap PIC microprocessors. The author faced challenges in designing the panels to function effectively within power constraints and without using through-hole components. By repurposing surplus PIC chips and using shift registers, the author achieved the desired bling effect. The innovative approach and nostalgic motivations behind the project added a unique charm. The author generously shared the schematics and code for free, showcasing a spirit of collaboration and creativity within the electronics hobbyist community.
