One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...

Vishay Precision Group launched two new ultra-high-precision Bulk Metal® Z-Foil current sensing resistors designed to improve LED brightness and efficiency in portable battery-powered applications.
