294: Ludicrous Numbers of LEDs (Repeat)
Mike Harrison, founder of White Wing Logic and host of the YouTube channel Mike's Electric Stuff, discusses his work designing large-scale architectural lighting installations using Microchip PIC microcontrollers and Texas Instruments TLC5971 LED drivers. He explains why he prefers white LEDs and RS485 daisy-chained architectures over NeoPixels for permanent, high-reliability projects, citing issues with reliability and color mixing. Harrison also details the logistical advantages of the PIC ecosystem, including Microchip's pre-programming services and the integrated MPLAB toolchain, which simplify production for his consultancy. The conversation covers his transition from general electronics consultancy to a niche in lighting design, his approach to managing power and voltage drops in large arrays, and his hobby of teardowns on obsolete scientific equipment like DNA analyzers.
