Boost Converters and Buck Converters: Power Electronics  -...

Controlling your AC loads using wireless power switch is not a new concept. Several commercial products from several vendors can be found on the market such as Xiaomi’s Mi Smart Socket Plug, SAMSUNG’s SmartThings Power Outlet and Sonoff Pow WiFi Switch from ITEAD. Using ESP8266...

The first watch to make use of the body's natural heat to uphold battery charge in wearables is now even being crowdfunded on Indiegogo. Who else but researchers from Texas A&M University (a hot place) came up with the solution. In today's wearables battery life is a...

by Jan Buiting @ elektormagazine.com: Harvard University researchers have developed a low-cost flow battery that stores energy in organic molecules dissolved in neutral pH water. In their report (see below) they claim that the new battery can run for a decade or more without...

Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor...

A custom 12V powerbank for Cube i7 Stylus from Muxtronics: Why would anyone even try to build a power bank – i.e. an external battery for charging mobile devices – these days? These things are commodity, it’s impossible to compete. Right? Well, that is until you find out that...

Peggy Lee @ newelectronics.co.uk discuss about MURATA's ultra thin supercapacitor. The DMH series from Murata is said to be the lowest profile supercapacitor. The product is designed for peak power assist duties in wearable applications and various other devices. Measuring 20 x...

pinko @ blog.exrockets.com wanted to regulate the power to a resistive load so he decided to build a PWM power regulator based on PIC18LF2550. In order to synthesize chlorates and perchlorates in the home lab it is always good to have a way to regulate the current flowing through the...
