To improve photonic and electronic circuitry used in semiconductor chips and fiber optic systems, researchers at the McKelvey ...

Equipped with printed templates, coin batteries, copper tape, LEDs, and scissors, participants set to work building their own digital cubes. The process involved cutting out paper circuits, applying ...

However, the current LED array driver circuits face challenges to balance high power and high speed. In this paper, we propose a driver circuit and a pattern display scheme that support high-power LED ...

Never miss a blown fuse again! This ultra-simple four-component circuit ensures you’re instantly alerted when a mains fuse fails, using an active flashing LED — no complex measuring needed, just smart ...

Once the capacitor voltage reaches 5V (or 5.4V as I couldn’t find a 4V3 Zener), the Zener pulls the transistor on and lights the leds. The 3n3 capacitor gives the circuit some positive feedback by ...

Look closely at the colored pixels on this pair of 8×8 RGB LED modules and you ... but look at this breadboard! The layout of his circuit is as equally impressive as the code he wrote to ...

[Fredzislaw100] out of Poland posted a video of a circuit that ... an inductor in one LED and one switch. [Alan]’s build is just a proof of concept – It’s still on a breadboard and doesn ...
