One year ago, I began building my own solar system to provide power for my village house.Initially I made a LM317 based charge controller and an Energy meter for monitoring the system.Finally I made PWM charge controller.In April-2014 I posted my PWM solar charge controller designs on the web,it became very popular. Lots of people

Hey Indigogo- We’re a group of engineers, educators, and published researchers. Over the last year, we’ve helped high schoolers and middle schoolers in New York City bring to life previously abstract concepts like algebra, capacitance in a circuit, and gravity. We wanted them to take this abstract material and turn it into something that they could interact with and form

Double the iPhone, double the teardown! With the iPhone 6 Plus laid out for inspection, we turn our attention to the smaller iPhone 6—though at 4.7″, it’s still a giant among iPhones. What was so big that Apple couldn’t fit it into the familiar form factor? Let’s shake it out onto the teardown table and

Researchers at Columbia Engineering and the Georgia Institute of Technology have reportedly made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2). The piezo effect is traditionally thought of as one property of hard crystalline quartz. Using this new material it would now be possible to

NXP has just released its new PMPB40SNA, a 60 V, 40 mΩ N-channel automotive MOSFET in a compact 2 x 2 mm DFN2020MD-6 (SOT1220) package. The DFN2020MD-6 is an industry first, featuring 100% wettable and therefore solderable flanks (side pads). This makes soldering and inspection much easier and is aligned with the automotive optical solder inspection requirements! It is the

Description Using CMOS process technology and innovative circuit techniques, the ADS5294 is a low power 80MSPS 8-Channel ADC. Low power consumption, high SNR, low SFDR, and consistent overload recovery allow users to design high performance systems. The ADS5294 has a digital processing block that integrates several commonly used digital functions for improving system performance.
