In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

In our hands-on review of the Digilent chipKIT Uno32, we posed the question of what the lasting appeal might be for a 32-bit Arduino work-alike. We felt it needed some novel applications exploiting ...

The thinner our devices become, the less room there is for speakers and other thicker components. Kyocera has a solution, however: it just modified its Smart Sonic Receiver conduction technology for ...

The small size of the Trip 80 series piezo alarm belies its huge sound output. A typical sound-pressure level of 103 to 106 dBa comes out of a case 26 mm in diameter by 22 mm high. As a result, it's a ...
