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 ...

One of the first things you learn in electronics is how to identify a resistor’s value. Through-hole resistors have color codes, and that’s generally where beginners begin. But why are they marked ...

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 ...

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 ...

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 ...

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

FiiO promises 'a brand new kind of listening experience' for your high-end headphones and IEMs with its new K13 R2R headphone amp/DAC.

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 ...

Pre-charge relays are used where a low-impedance source such as a battery has to be switched into a large bank of un-charged capacitors by a main relay or contactor. To protect the main contacts from ...
