"Tin whiskers" could triple the capacity of lithium-ion batteries

For over 60 years, electrical engineers have been trying to minimize the problem of tin whiskers. Growing on tin-plated electronics, the needle-like structures get up to ten millimeters long, and can cause short circuits. Instead of trying to eliminate them, however, Washington State University’s Prof. Grant Norton has been looking into ways of growing them – albeit in a controlled manner. His research has led to the creation of a tin battery anode, which he claims could triple the capacity of lithium-ion batteries.Read More

Special solar cells produce electricity from underwater sunlight

Although solar cells are proving indispensable for powering things such as electronic sensors on dry land, sensors located underwater have typically had to rely on batteries, or electricity piped in from photovoltaic panels situated above the surface. That could be changing, however, as scientists from the U.S. Naval Research Laboratory have recently developed functioning underwater solar cells.Read More

Wexler launches the Flex ONE: First flexible ereader based on LG Electronic Paper Display

With the launch of the aptly-named Flex ONE, Wexler is first to commercially launch a flexible ereader based on LG's Electronic Paper Display (EPD) technology. Wexler additionally claims that the Flex ONE is the thinnest and lightest ereader in the world. Weighing in at a mere 110-g (3.9-oz), the 4-mm (0.16-in) thick ereader delivers on LG's promise that EPD-based products would follow soon after the technology was announced.Read More

Modder combines solder iron and air pistol to create awesome soldering gun

Electric soldering guns like the ones made by Weller are so named due to a passing resemblance to a hand gun, but to me they've always looked more like a B-movie imitation of a classic phaser from the Star Trek TV series. If you're wanting a soldering gun that really looks like a pistol, then take a look at Mike Warren's mod, which combines an old air pistol and a battery-operated soldering iron into an oddly pleasing hand-held heat weapon. The gun even uses the magazine clip as a battery pack.Read More

Knut internet-connected sensor keeps you in the know via email

Our lives are very connected these days. You can check in on friends and family, your car and your home within seconds by typing a few words and pushing a few buttons. Despite this, there are still many pieces that remain cut off from our networks by physical space. The Knut sensor hub aims to connect a few more of those pieces. Read More
