The circuit was designed to produce a digital roulette that will display the result using a 7-segment LED display. Roulette – refers to a game of chance played at a table where a small ball is made to ...

A radical new approach to display screen technology could halve production costs, reduce harmful waste, and deliver brighter, more energy-efficient screens for our smartphones, smartwatches, and even ...

Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the LED display unit. On the otherhand, if it is based on discrete ...

Displays built out of plastic instead of glass would be a gadget lover’s dream: they’d be rugged and lightweight, and they should be inexpensive to make on “roll-to-roll” systems similar to those used ...

Since the invention of liquid crystal displays in the mid-1960s, display electronics have undergone rapid transformation. Recently developed organic light-emitting diodes (OLEDs) have shown several ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

Here at Hackaday we can never get enough of odd clocks, and we’re delighted to see [Dan O’Shea]’s creation called the Wifi-Telnet-FPGA-NTSC Drunk Wall Clock. That mouthful is an accurate description ...

KENOSHA, Wis. — Snap-on Tools, a subsidiary of Snap-on Inc., has debuted the Digital Display Circuit Tester (EECT400), designed to take the guesswork out of voltage readings, the company said. The new ...
