Abstract: Low-voltage organic-field effect transistors (OFETs) using relaxor ferroelectric polymer poly (vinylidene fluoridetrifluoroethylene-chlorofloroethylene) P (VDF-TrFE-CFE)) were fabricated.

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.

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...

We aren’t sure if [Looking Glass Universe] didn’t trust the accepted number for Planck’s constant, or just wanted the experience of measuring it herself. Either way, she took some LEDs and worked out ...

Abstract: We report the first demonstration of displays driven by embedded transistors that were additively manufactured entirely by aerosol jet printing. The backplanes of the liquid crystal displays ...
