Photocouplers optically links, via transparent isolating material, a light emitter and a photodetector. Used as an interface between circuits with different ground potentials, photocouplers replace ...

Early last spring, we featured a book review, as part of our occasional Books You Should Read series. Usually these are seminal tomes, those really useful books that stay with you for life and become ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

When a Hackaday article proclaims that its subject is a book you should read, you might imagine that we would be talking of a seminal text known only by its authors’ names. Horowitz and Hill, perhaps, ...

Researchers in Italy have created the first integrated circuit to combine two transistors made from the “wonder material” graphene. By adapting a technique used to fabricate silicon transistors the ...

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got the ...

If you’ve ever wanted to learn the basics of circuit design, we’ve got a very cool deal running in the HotHardware Shop you’ll probably want to check out. A Circuit Scribe Basic Kit is on-sale for ...

At the December 2021 IEDM conference (a conference for people who design advanced semiconductors), IBM announced it was turning transistors on their heads to keep Moore’s Law scaling alive. The new ...

Small electronic components "A transistor"Hundreds of millions of people are used in smartphones and PCs, which are indispensable to many people, as well as running a train, shedding music from ...
