[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 ...

The project is comprised of an accelerometer, controller, MCU, and a few LEDs on the LED Puck board where the tilt of the board is sensed by the accelerometer and the appropriate LED lights up to ...

The capabilities of this small and nice chip on measuring acceleration and orientation in space are shown in this project where the 3-axis ADXL330 accelerometer is interfaced with an AVR ...

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.
