TL;DR
Chris Maher has designed an impressive wall-sized LED matrix, comprised of 2,500 individually addressable LEDs, that’s both affordable and simple to construct. This 50×50 grid is powered by a single 12V supply and controlled by a single unit, utilizing 18 rolls of SK6812 LED strips. Each strip is cut into segments to create a manageable power and data structure, striking a balance between visual quality and power requirements.
