This STM32 Turns 3,000 Mechanical Pixels Into a Real-Time Fluid Simulator With Joystick-Controlled Gravity Maker Tim Alex Jacobs has turned nearly 3,000 old electromechanical flip dots into an unusual real-time fluid simulation display. Instead of using an LCD or LED panel, the project uses eight salvaged flip-dot panels, where every pixel is a small magnetic disk that physically flips between two positions. which is black and yellow. The result is a display that not only shows the movement of the… |
