Technology moves fast. What seemed cutting-edge a decade ago now collects dust in attics and thrift stores. But here’s the thing—most of us remember these gadgets for their mainstream glory days, not ...

Hackaday gets results! Reader [John] saw our recent Fail of the Week post about a “sand matrix printer” and decided to share his own version, a sand-dispensing dot matrix printer he built last year.

Researchers have developed an ultra-thin 3D display with a wide viewing angle, clear image quality and vivid display depth.

We’re already coming up on Halloween, and the year is officially in its final third … and a lot of new tech and gadgets have already been announced. Naturally, the product release cycle keeps on ...

Inorganic LEDs are light-emitting diodes (LEDs) made from a crystalline semiconductor. The optical emission wavelength can be selected by varying material composition. Example active regions include ...

Abstract: We report a novel active split structure of low-temperature polysilicon (LTPS) thin film transistor (TFT) on polyimide (PI) substrate showing robust electrical performance under mechanical ...

Abstract: This study aims to explore the application of a resonant cavity structure in quantum dot full-color display technology, with a particular focus on the impact of spacers on display ...

The small dot-matrix display on the back of the phone seems superfluous, and it lacks any official water resistance. The phone incorporates a pair of useful side-mounted buttons that can be mapped to ...

When you press the button, the LED matrix displays a dice roll animation and stops on a random number between 1 and 6. Built using SPI communication with the MAX7219 driver.
