A preliminary examination into the fire at a building at Hyderabad's Gulzar House in which at least 17 people lost their lives indicated that a short circuit caused the massive blaze, a fire ...

This project creates beautiful LED patterns (like numbers and stars) using a 555 timer in astable mode and a CD4017 decade counter, without any microcontroller. Ideal for electronic art and ...

This is a simple LED driver circuit using two 555s and a pair of NPN/PNP transistors to drive several LEDs meant to outline a small sign. Designed with my son for a St Patrick's Day project, in KiCAD.

A pair of current switches, which is used for driving the LED string, employs an adaptive bias circuit for low-power dissipation. A differential pre-amp drives the large-size current switches to ...

These judges ruled against Trump. Then their families came under attack. An intimidation campaign against federal judges who have ruled against the Trump administration has strained the judges and ...

The LEDs are available in 850nm and 940nm wavelengths, tailored to various sensing needs. The 850nm models deliver optimal sensitivity for camera-based detection and phototransistor use, while the ...

🚀I’d like to share my latest achievement where I designed my first PCB board, the 8-LED Chaser Circuit, using KiCad. A step in the many to come on my journey of progress in electrical ...
