Every Pixel Has Its Own Microcontroller Imagine a display where every single pixel has its own brain. That's the ambitious idea creator bitluni set out to bring to life in a six-month engineering project. Instead of relying on a central GPU, the display turns every pixel into an independent computing node. The ultimate goal is a 65,536-core QVGA display, while the first working prototype already features 8,192 RISC-V… |

Clock Uses Water Bottles as Pixels With Membrane Pumps and Servos Maker Strange Inventions has built a water-based digital clock in which 60 small bottles act as individual pixels, collectively forming numerals to display the time. The bottles, sourced at 10 cents each, brought the total project cost to approximately $580. Each bottle is filled or emptied with dyed water to switch its pixel state on or off, with the display controlled by a microcontroller… |
