Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on a ...

I have a drawer full of USB cables and every time I want to connect a device, I have to try them out. USB-C was supposed to simplify things: One cable for everything, that was the promise. In practice ...

China has suspended a ban on approving exports of "dual-use items" related to gallium, germanium, antimony and super-hard materials to the U.S., the commerce ministry said on Sunday. Gallium, ...

The ability to make a very miniature on/off switch changed the world. These tiny switches, known as transistors, make up the basis of all modern computing—they drive your cell phones, your bank ...

The first transistors were point contact devices, not far from the cats-whiskers of early radio receivers. They were fragile and expensive, and their performance was not very high. The transistor ...

If you’ve worked with germanium transistors, you’ll know that many of them have a disappointingly low maximum frequency of operation. This has more to do with some of the popular ones dating from the ...

Shrinking silicon transistors have reached their physical limits, but a team from the University of Tokyo is rewriting the rules. They've created a cutting-edge transistor using gallium-doped indium ...
