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 ...

Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...

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.

An ongoing trend toward miniaturization of virtually all electronics is accompanied by the demand for a reduction in power consumption. As the pressure to fit as much functionality, and thus circuitry ...

I picked up six new triple red LED fans from Xoxide and they arrived today. My plan is to revamp all of the cooling in my case with these new fans, but I want to modify the fans to be able to switch ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...

[Stephen Carey] wanted to spruce up his car with sound reactive LEDs but couldn’t quite find the right project online. Instead, he wound up assembling a custom bass reactive LED display using an ESP32 ...

British couple Lenny and Meriel Lenfesteys use parts from computers and electronics kits to create tiny figures. In this picture, called 9V Tragedy, a pair of LED-headed characters console each other ...

Hi all, back again after realizing that my previous project was a bit more ambitious than I'd have time for right now. I have a need to run several different components from battery, and I'm wondering ...
