MatTris - Tetris on an LED Matrix
Things used in this project × 1 × 1 Meet MatTris, a DIY Tetris console built completely from scratch. I was born in 1998, and my first introduction to Tetris was through those monochrome LCD handhelds that came loaded with 10 to 100 built-in games. That’s what inspired me to build my own version using modern hardware. Years later, while working with addressable LEDs and microcontrollers, I wanted to recreate that same experience, but using hardware I designed myself.
WaveFORM : the Background Sound Visualizer
Things used in this project × 1 Greetings everyone and welcome back. WaveForm: The Background Sound Visualizer transforms one of the most common yet invisible elements of our environment—sound—into a dynamic visual experience. Sound is all around us, all the time. We talk, type, walk, and listen to fans, ambient noise, traffic, and music, but the actual shape of those sounds is something we never see with our eyes. They exist as vibrations in the air, completely hidden from our visual senses.
Neopixel Giant Edition
Things used in this project × 1 × 1 Meet Giant Neopixel, a scaled-up version of the popular WS2812B RGB addressable LED. In our giant version, we used the exact drawing of the original 5050-package LED and recreated it as a 150×150 mm model that works just like its real counterpart. To make this work, we designed a custom circuit built around a single WS2811 IC connected to nine 5050 RGB LEDs, all driven through a MOSFET-based switching stage.
