by Vladimir Rentyuk @ edn.com: Most engineers know that they can use an inexpensive, three-terminal adjustable regulator, such as Fairchild Semiconductor’s LM317, as an adjustable regulator to only some necessary value of voltage, such as 36 or 3V. This value cannot be less than...

by Rob Matheson @ phys.org: An exotic material called gallium nitride (GaN) is poised to become the next semiconductor for power electronics, enabling much higher efficiency than silicon. In 2013, the Department of Energy (DOE) dedicated approximately half of a $140 million...

MAINS Power Dimmer / Switch Module project by Tracker J: Now it’s about time to talk also about what many of you has asked for: DIMMING! It’s a total different story, little bit complicated but, as you will see, not so hard to understand. General considerations: There are...

New series of Sunon fans with IP68 protection brings reliability even to conditions, where a usual fan doesn´t withstand too long… Still more noise and vibrations and in extreme case even a total malfunction – this is a typical “end” of the fan after a long-time operation...

This design of acoustic sound receiver features low power operational amplifier. It has rail-to-rail input/output and 0.85mA supply current per amplifier. It uses piezo speaker as its microphone that can be attached to easily due to its size and dimension. The circuit is comprised...

by Ardumotive_com @ instructables.com: Today I will show you how to make your own 7 segment - 2 digit - thermometer with Arduino uno and DS18B20 temperature sensor. I prefer to build my own arduino based circuit by using the ATmega328p uno possessor, but this is optional for you....

by Sinjin Dixon-Warren @ chipworks.com: The Intel® RealSense™ gesture camera represents another foray by Intel into the consumer products space. The camera has been incorporated into the Lenovo ThinkPad Yoga 15. Intel disclosed at IDF14 that the device is formed using three...

More exactly, we talk about switching-off a device. Marquardt 1550 Eco Switch enables this extraordinarily easily. Do you know a situation, when a seemingly usual thing is fact not that usual... Whether it´s a car with a hybrid drive or a lot of devices which we meet every day...
