Latching Push-Button Initial State

Fri, 24 Feb 2017 10:14:08 EST

Dear Engineers, I've nicked this neat design for a power-switch of the web. It works as expected with the exception of the initial state. Connecting the 0.1uF capacitor to the power rail should keep the output low, when power is first applied, but it does not. Any suggestions? This is the actual s

The extraordinary adoption and number of design-ins for field-programmable logic arrays (FPGAs) — in many cases, pushing microprocessors, and DSPs aside — has led to an unforeseen outcome: FPGAs are now expected to have an ever-growing number of I/O ports. The Texas Instruments FPC401 is



Resistant Superbugs

I remember when I first watched War of the Worlds. I was in high school and already nervous about seeing what I deemed a “scary” movie. The movie was almost over when a huge thunderstorm hit the area and the theater lost power. My friend turned to me and said, “Isn’t this how
