[Fearless Night]’s slick dual hourglass doesn’t just simulate sand with LEDs, it also emulates the effects of gravity on those simulated particles and offers a few different mode options. The unit ...

I designed an accelerometer-based inclinometer for a piece of medical diagnostic equipment (non-portable) a couple of jobs ago. The output of the accelerometer was an analog signal that was passed to ...

Accelerometers turn motion into measurable signals. From tilt and vibration to g-forces, they underpin countless designs. In this “Fun with Fundamentals” entry, we demystify their operation and take a ...
