Rechargeable

The Solderdoodle is designed to be charged from a USB port

The days of being tied to a mains outlet to do a bit of soldering are long gone, but what about the techie on the go who doesn't want to be lumbered with chargers, batteries, and cans of gas? Solderdoodle is a partly 3D printed device that can be charged using a standard USB cable.  Read More

The USC organic redux flow battery (not pictured) replaces metals with water-soluble organ...

Lithium-ion batteries have made portable, rechargeable electronics commonplace. Unfortunately, they do have some glaring drawbacks, including heat issues, being made with rare, toxic elements, and the fact the technology doesn't scale up very well, which limits applications. A team of scientists at the University of Southern California (USC) is working on an alternative in the form of a water-based organic battery that is not only cheaper and more environmentally friendly, but also holds the potential for scaling up for use in wind and solar power plants as a means to store large amounts of energy.  Read More

Electric skateboards can be a great way to get around town, but it's a different story when it's time to get off the board. The battery and motor that make things so cruisy when the board is underfoot have the opposite effect when its tucked under your arm. And it's not just the weight, with electric skateboards generally featuring a longboard form factor that can be unwieldy to carry. That's why Adam Riley of Epic Skateboards has developed the Caseboard, an electric skateboard that folds in half for carrying like a briefcase when not getting users from A to B.  Read More

An international team of researchers has developed a supercapacitor composed of graphene and carbon nanotubes that is claimed flexible enough to be woven into clothing and potentially powerful enough to offer a real alternative to batteries for use in portable devices. Capable of being charged and discharged in excess of 10,000 cycles, the new supercapacitor also promises to be significantly lighter, faster to charge, and more robust than current battery technology.  Read More

There can be little doubt that people love their mobile devices. But, by leaving them high and dry at the most inconvenient of times, this love generally doesn't extend to the batteries that power said devices. New microbatteries developed by researchers at the University of Illinois at Urbana-Champaign (UIUC) that measure just a few millimeters in size, yet are powerful enough to power a mobile phone may be more likely to inspire a little love.  Read More

The Instacube is an Android-powered digital photo frame for Instagrammers

Silicon Valley-based Design to Matter (D2M) is aiming to provide the legions of Instagram users with an alternative to viewing their shots on a phone, tablet or PC. The company’s Instacube is an Android-powered digital photo frame to which users can wirelessly push their Instagram stream over Wi-Fi.  Read More

The Ouroboros has customizable side panels allowing for ambidextrous use

Named after an ancient symbol representing constant re-creation, the Ouroboros gaming mouse from Razer is all about customization and choice. The device features a fully adjustable body and symmetrical, ambidextrous design, with adjustable arched palm rest and back, and two interchangeable side panels. This means that the length, tilt angle and side configuration are all adjustable, giving the user significant room for personal customization.  Read More

The Trioh! features a built-in rechargeable Lithium Ion battery

It’s a scenario many of us are familiar with: the power goes out and the sole flashlight kept at the bottom of the kitchen drawer has either disappeared, or else been harvested for batteries, leading to much fumbling around in the dark. Portland, OR native Greg Hinzmann aims to prevent this situation by designing a flashlight which is so beautiful that you’ll want to show it off and so have it to hand, should the need arise.  Read More

A green, rechargeable battery that is suitable for powering electric vehicles and stationary power storage applications, and that would survive tens of thousands of charge cycles in a useful life of 100 years without loss of capacity. What could be a better innovation for our times? Such a battery has been developed, and recently improved by Stanford researchers. Oh, one other thing. The battery was invented by Thomas Edison in 1901.  Read More
