Beyond the power variant, it sometimes seems as though we rarely encounter a discrete transistor these days, such has been the advance of integrated electronics. But they have a rich …read more Continue reading Make Your Own Point Contact Transistor
Often, the only liquid level indicator you need is your eyes, such as when looking at your cold beverage on a summer’s day. Other times, though, it’s useful to have …read more Continue reading A Simple Liquid Level Indicator With a Single IC
In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors …read more Continue reading All About PNP Transistors
Building a retro computer of some sort is a rite of passage for many of us, with some building replicas or restorations of old Commodores, Ataris, and other machines from …read more Continue reading Homebrew Computer from the Ground Up
Not every computer can make use of a disk drive when it needs to store persistent data. Embedded systems especially have pushed the development of a series of erasable programmable …read more Continue reading Reprogrammable Transistors
Researchers have used off-the-shelf components to create a sensor device that is not only cost-effective but can quickly detect 32 different pathogens and has sensitivities on par with the state-of-the-art biosensors used in pathology labs. The novel d… Continue reading Medical lab-on-a-chip runs 32 pathology tests at once
Researchers at UCLA recently developed what they are calling a thermal transistor: a solid-state device able to control the flow of heat with an electric field. This opens the door …read more Continue reading A Transistor, But For Heat Instead of Electrons
Building things in a lab is easy, at least when compared to scaling up for mass production. That’s why there are so many articles about fusion being right around the …read more Continue reading The Geometry of Transistors
AI machine learning uses so much computing power and energy that it’s typically done in the cloud. But a new microtransistor, 100X more efficient than the current tech, promises to bring new levels of intelligence to mobile and wearable devices.Continu… Continue reading Ultra-efficient machine learning transistor cuts AI energy use by 99%
We all know, at least intellectually, that our computers are all built with lots of tiny transistors. But beyond that it’s a little hard to describe. They’re printed on a …read more Continue reading CPU Built From Discrete Transistors
