Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

Fidget toys are everywhere these days. A particularly popular type simply puts some keyboard switches on a plate to provide a certain type of clicky satisfaction. [wjddnjsdnd] took that concept a ...

Nano-sensors that work without batteries or wires could pave the way for more comfortable, less obtrusive sleep and health care monitoring at home, according to scientists at the University of Surrey.

Battery-free nano-sensors developed at Surrey University could enable comfortable, unobtrusive sleep and health monitoring at home, using movements such as breathing or turning during sleep to ...

Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen ...

Most polymers don’t mix—and that’s the point. Polymer alloys succeed by engineering the interface: use thermodynamics to predict separation, processing to sculpt morphology, and compatibilizers to ...

Cylinders and tubes: The structure of the helium detection device was inspired by the Japanese bamboo-weaving technique known as Kagome-biki. This triangular structure (shown in detail at left) helps ...

The best smart thermostats we've tested can control your home's heating and cooling with your phone or voice—and might help you save on energy costs. I’ve been working with computers for ages, ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

Abstract: This paper presents an dual-mode active frequency control (DM-AFC) technique utilizing dynamic stiffness compensation to address temperature-induced zero bias drift and scale factor ...
