Flip-Dot Display Turns Fluid: A maker swapped silent LEDs for a room-filling flip-dot panel that physically clacks out real fluid physics, steered by a joystick and a hidden IMU.
Raspberry Pi Pico Revives: A maker resurrected a discontinued 1980s Heathkit packet radio modem by making a $4 Raspberry Pi Pico run the exact original firmware itself.
Overclocked RP2350 Pushes 1080p: A Pico-class chip driving 1920x1080 over DVI, with 520 KB of RAM and no framebuffer. Here is the overclock, the scanline trick, and the wiring gotchas.
Animate Halloween Skeleton Raspberry: Turn a ₱150 plastic skeleton into a spooky animatronic with a Raspberry Pi Pico, four 9g servos, and a distance sensor. Wiring and power tips inside.
Someone Squeezed Generative AI: Five seconds, 520 KB of RAM and about a dollar of silicon: the RP2350 inside the Raspberry Pi Pico 2 is now generating 128x128 AI faces on-device.
Parody Apple Laptop Reborn: A 20-year-old Apple parody became real hardware: an RP2350 running FreeRTOS, DMA-driven graphics and an alphabet you tap out on one capacitive pad.
Clough42's GPS Clock Spins: A GPS module, a Raspberry Pi Pico, and two TMC2208 drivers spin machined wheels to show time that never needs setting. Here is how the build works.
