This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

A series looking back on the 30th anniversary of the 1995 Indians begins July 7 on these pages, so now seems the appropriate ...

A timer-controlled doorbell device has been developed using two 555 timer ICs in monostable mode, combined with a relay ...

The celebrated ‘555’ IC was originally developed as a timer device, but over the years this golden oldie has been used in all sorts of other applications, including some never imagined by its ...

Through 81 games, the Nationals have a lot to improve upon with only a handful of positives as the trade deadline approaches ...

This project features a custom 3D-printed 'Mortal Kombat' trophy shell paired with a basic NE555 timer circuit in 'astable mode', producing a smooth 'breathing' LED effect—mimicking the gentle pulse ...

From spacecraft engineers to open-source rebels, these innovative women are changing the face of what engineering looks like, one bold idea at a time.

Given the performance decay of high-power light-emitting diode (LED) chips over time and package condition changes, having a reliable output light for sensitive applications is a point of concern. In ...

The order is stayed until noon tomorrow (June 13), and I expect the federal government will ask the Ninth Circuit and, if necessary, the Supreme Court for a further emergency stay.

The pending order by 9th Circuit also means the Trump administration can keep some 4,000 California National Guard troops and 700 Marines in LA under its control until further notice.

MEXICO CITY — NASCAR’s arrival in Mexico City has been hard to miss, even in a metropolis with a population of 22.5 million people. If you weren’t close enough to hear the Cup Series haulers ...
