Weekend Project: Build a Giant LED Pixel Display

I love LED pixels: bright, easy to control, cheap, and so versatile. My last project was an Ambilight TV backlight, but generally I’m just in love with intelligent lighting. Today, we’ll be turning them into a big pixel display that can be hung on the wall of your office; either to serve a useful purpose, or just look incredibly pretty.

This is a relatively simple project that just takes time to construct, but can be a little fiddly when connecting the strands of LEDs. The basic idea is laying down strips of LED pixels in snake pattern on the back of the photo frame. The front will be frosted to help diffuse the light.

From there, it’s mostly a question of which software to use, depending on your needs – I’ll get you started with some demo code and pointers, then revisit the software angle in a later article as we figure out how to pull information like notifications and stock prices onto the display.
