Spintronics is an emerging technology exploiting both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. Spintronics differs from the older magnetoelectronics, in that the spins are not only manipulated by magnetic fields, but also by electrical fields. Spintronics emerged from discoveries in →

You have most probably used 7805 voltage regulator many times. It is a simple way to get regulated +5V power supply. A Detailed Look at the 7805 Voltage Regulator post at hackaday.com points to an an amazingly detailed article about its theory of operation and implementation of 7805 regulator. As some elements looked a bit odd during →

Android devices can be used as signal generators and signal analyzers. It is easy when all you want is to get the signal out of the speaker or headphone connector, and you are happy to analyze what internal microphone in the device receives. But what if you want to feed some external signal into your →

I have posted some teardowns of serveral electronics devices and have some notes on their electrical safety. Examples of ones with questionable safety were this is tiny USB charger and this USB charger. The later USB charger posting has also example of power supply that seems to have properly built safety in it. But how →

Watch a Hacker Fry a Hair Dryer With Her Radio article shows that a handheld directional radio antenna can be used to to fry a ground fault circuit interrupter, or GFCI: GFCIs integrated into household appliances like hair dryers and heaters or wall outlets, mischievously switching them off or making the plugs shake, spark and →

http://www.electronicproducts.com/Power_Products/Invertors/Advanced_solar_microinverters_lay_groundwork_for_smart_grid.aspx In the span of a few years, the photovoltaic (PV) microinverter has evolved from an intriguing and potentially disruptive technological advancement to a market-leading product category in the residential and commercial solar installation market. Millions of devices have been deployed and have already helped genrate terawatt-hours of electricity from hundreds of thousands of rooftop →

Hot Chips: A Symposium on High Performance Chips has been known as one of the semiconductor industry’s leading conferences on high-performance microprocessors and related integrated circuits. It is concentrates on real products and realizable technology. The conference is held once a year in August in the center of the world’s capital of electronics activity, Silicon Valley. →
