Resistors are one of the fundamental components used in electronic circuits. They do one thing: resist the flow of electrical current. There is more than one way to skin a cat, and there is more than ...

If you wave your hand under the water's surface, you get a pattern of ripples on the surface shortly thereafter. Now imagine working that backwards: you want to produce particular ripples on the surfa...

If any of you have ever made a piece of clothing, you'll know some of the challenges involved. Ensuring a decent and comfortable fit for the wearer, because few real people conform exactly to commerci...

Researchers at Tufts University are experimenting with smart thread sutures that could provide electronic feedback to recovering patients. The paper, entitled “A toolkit of thread-based micro…

The BeagleBone is a very popular single board computer, best applied to real-time applications where you need to blink LEDs really, really fast. Over the years, the BeagleBone has been used for stan...

There’s hardly a day that passes without an Arduino project that spurs the usual salvo of comments. Half the commenters will complain that the project didn’t need an Arduino. The other …
