Programmer Hacks Own Wi-Fi Using Electromagnetic Waves
Jason Cole, a programmer and Ph.D. student at Imperial College in London, created an Android app that allows users to hack their own Wi-Fi using electromagnetic waves. Many believe it’s best to avoid electromagnetic radiation; however, not all believe electromagnetic waves are bad. Electromagnetic waves carry Wi-Fi signals to all electronic devices and are the foundation of … [Read more...]
Multilayer Ceramic Capacitor Increases Capacitance by 50 Percent
The first commercially available X5R/X6S 330μF multilayer ceramic capacitor has been produced by TAIYO YUDEN. Compared to the previous products, in the same size capacitor, capacitance increases by more than 50 percent. This capacitor was designed to replace electrolytic capacitors and to reduce noise and smooth ripple current in power supply circuits. It offers longer product … [Read more...]

New Law Focuses on Security of U.S. Power Grid
Arizona lawmaker, Rep. Trent Franks, has introduced new legislation to push the U.S. Department of Homeland Security (DHS) to focus more on U.S. power grid security. Franks reportedly fears electromagnetic pulse blackouts and geomagnetic storms that can overload and disable U.S. power grids, thus interrupting everyday life. "The Critical Infrastructure Protection Act will … [Read more...]
ROHS and CHINA-ROHS Compliant Power Connectors Introduced
Schurter introduces its new high-temperature power connectors according to IEC/UL 60320. The appliance inlet, series 1681, offers screw-on or snap-in mounting options. The cord connector is available in two different designs: a straight series (1658) or an angled series (1659). “The high-temperature appliance inlets and cord connectors are designed according to IEC for 16 A at … [Read more...]
Smart Meters Create Concerns About Privacy
Recently in Michigan, DTE Energy has installed over two million Smart Meters, which are wireless boxes that can measure and report energy and electricity usage through radio frequency waves. The meters can be useful during power outages and harsh storms – the meters will alert officials of power losses and electricity will be restored faster. However, Michigan residents are … [Read more...]
Sunspot Could Create Solar Flares and Superstorm
A sunspot, big enough to fit 10 Earths inside of it, known as Active Region 12192 has just aligned with Earth and could cause major problems. This sunspot is the largest to be seen in over 24 years. The sunspot began facing Earth in October and created six eruptions; however, it did not create any coronal mass ejections (CMEs). The sunspot then disappeared for two weeks before … [Read more...]
