With surface-mount components quickly becoming the norm, even for homebrew hardware, the resistor color-code can sometimes feel a bit old-hat. However, anybody who has ever tried to identify a random ...

Messing around with Arduino can lead to some fun projects — like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...

What’s your favorite value of resistor? 1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are supposed to ...

The electrical system of an automobile is likely the system understood the least by most Mopar owners, but compared to late-model vehicles the electrical and ignition system of a classic Chrysler ...

The resistor is one of the simpler electronic components. Engineers seldom examine resistor characteristics until there's a resistor-related problem with a circuit design. You can probably resolve 90% ...

Designs requiring space-grade components must take into account the variances in component values that can occur over time. This is especially true for resistors, which can exhibit significant changes ...

A positive temperature coefficient resistor (PTCR) is a resistor that varies its resistance with its temperature. A resistor that changes its resistance characteristics as a function of its ...

Electro-optical and photonic devices have made great progress in their level of integration and performance. However, they do ...

The mystery of adding LED lights to a modern BMW with CAN Bus (Controller Area Network) electrical system is easy to resolve. The “smart” CAN Bus smells a rat when you pop in an LED brake light or ...

Integrated photonics has become a multi-billion-dollar industry, but it is feeling the heat—literally. Subscribe to our newsletter for the latest sci-tech news updates. An increasingly important ...
