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 ...

Although not really a cost-effective or a required skill unless you have some very specific needs not met by off-the-shelf power resistor options, making your own own wirewound power resistor is ...

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 ...

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 ...

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 ...

An LM555 timer paired with an NTC thermistor makes a simple, configurable ON/OFF thermostat for heating or cooling.

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 ...

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 ...
