Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect. Researchers at the ...

One of the great things about the Hackaday community is how quickly you find out what you don’t know. That’s not a bad thing, of course; after all, everyone is here to get smarter, right? So let’s ...

For more than a century, scientists have relied on separate tools to measure the three core building blocks of electricity: volts, ohms, and amps. Each describes a different piece of how electricity ...

Until recently, the limiting factor in high-temperature electronics has been the degradation in semiconductor properties of the active components used. However, with recent advances in ...

Drive smoothly, say goodbye to 'road rage': When driving, try to be smooth, anticipate road conditions in advance, and ...

I'm building some speakers today(yay!) and I don't know enough about electronics to figure this out. I'm using three-way crossovers, and it has big resistors on it. Do I still need some for the piezo ...

Memristors, or “memory resistors,” are the leading candidate for replacing synapses in a neuromorphic (brain-like) computer.

A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...
