I shared this on Twitter , but thought I’d share here as well. Its a simple build that’s a lot of fun when it’s done.
This project is a simple LED matrix constructed by taking a single 5cm spacing LED string and sewing it in a zigzag pattern to a 20" square decorative pillow insert. The 5cm LED spacing allows for a 10x10 matrix on a 20" square pillow. After sewing the LED string to the pillow insert, I covered the LEDs with a layer of polyester batting for diffusion, then slid the pillow and batting inside a white velveteen decorative pillow cover. I spent about 8 hourS putting it together, and 90% of the time was just sewing down the LED string, which I did while watching TV (might have gone faster without the TV) I’ve attached some photos of the construction process
