Raspberry Pi Model B+ has more slots, less power demand

Raspberry Pi Model B+ has more slots, less power demand

The Raspberry Pi Model B is getting another facelift and no, this isn't a Raspberry Pi 2, and all that is implied by that major name change. Instead, the B+, as the name would suggest, is a very incremental improvement over the existing Model B, giving makers and hackers more connectivity options but retaining the same core and keeping compatiblity with the existing software and peripherals.

Boosted batteries teased from Li-Ion visualization research

Boosted batteries teased from Li-Ion visualization research

Longer lasting, higher capacity, and cheaper rechargeable batteries could be in the pipeline as scientists finally figure out exactly what's going on inside, potentially opening the door to increased electric car range and smartphones that spend less time plugged in. The microscopic imaging techniques, developed by researchers at the US Department of Energy's Pacific Northwest National Laboratory, are expected to make it possible to examine what's happening within a live lithium-ion battery, particularly around areas of chemistry which so far power research has struggled to understand and refine for longer-lasting gadgets.

Powerslayer smart charger aims to eliminate wasted energy, hits Kickstarter goal

Powerslayer smart charger aims to eliminate wasted energy, hits Kickstarter goal

Devices that need charged on a regular basis, such as smartphones and tablets, are apt to be left plugged in for long periods of time, even if the battery itself has reached it full charge. Though charged, there is still an energy draw that is taking place, which results in wasted power, and, though not much on an individual scale, it adds up when multipled by millions of gadgets. That is where the Powerslayer comes in.

NASA shelves fuel-efficient tech, effectively slashes outer planet exploration

NASA shelves fuel-efficient tech, effectively slashes outer planet exploration

NASA this weekend all but abandoned a money-saving technology due to a lack of money. You read that correctly. The space agency's budget woes are so suffocating that it can't even get the funding to develop ways to make missions more efficient. In this case, the efficiency would have been massive: the Advanced Stirling Radioisotope Generator (ASRG)--the program that just effectively got the ax--would have let many space missions require just one-fourth the fuel they currently need.

USB PD replacing current standard: why this is excellent

USB PD replacing current standard: why this is excellent

The word is spreading here near the end of 2013: USB is over, if you want it. USB PD (Power Delivery) is set to be the new standard for the next generation, working with standard specifications set to start taking effect as early as 2014. This technology may very well change the way we power electronics, first and foremost because it's able to output up to 100 watts of power, 10 times that of today's current best in regular ol' USB technology.

The Practical Meter aims to tell you how fast your phone is charging

The Practical Meter aims to tell you how fast your phone is charging

If you've ever wondered if plugging your smartphone in to one power outlet was charging it up to full power faster than another, there's a tiny device made by a fellow named David Toledo that'll get you thinking. What you're seeing here is a sort of half-way point between a USB port and your USB-based power cord. What the Practical Meter will do is show you a number of lights depending on how fast your device is powering up. With this information, you'll be able to find the most optimized power source and charge your device up as fast as possible.
