There was a time when you had to travel to your nearest arcade or beg your parents for a Game Boy if you wanted to play Tetris. Today, the iconic, addictive puzzler is available online for free and in ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

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 ...

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 ...

Ok, we’ll admit it. If you asked us what the first transistorized computer was, we would have guessed it was the TC from the University of Manchester. After all, Dr. Wilkes and company were at the ...

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 ...
