Can your sweat power your phone in the future?

California researchers are on the brink of harnessing the power of human perspiration – yes, your sweat – to generate energy enough to power your electronic handheld devices. This is done, for now, through a temporary “tattoo” which has a sensor imprinted on it that could turn sweat into electrical power.

Amazon celebrates FAA gadget ruling with Kindle push

Following a committee recommendation that arrived in September, the FAA officially announced that mobile devices would soon be available for use in "all phases of flight." While not every airline and flight has officially come on board, we have seen select airlines and flights begin allowing wider use. This likely comes as good news for frequent travelers, however it looks like Amazon is also in the mood to celebrate.

FAA approves mobile device use for “all phases of flight”

Back in September the Federal Aviation Administration (FAA) committee recommended allowing the use of gadgets during takeoff and landing. Given the committee recommendation, it seemed likely that the approval would come and the rules would be lightened. Of course, nothing could change until the official word was received. That said, coming by way of an FAA issued press release, that approval has arrived.

FAA committee recommends the use of gadgets during takeoff and landing

It looks like airlines may soon begin lifting some of the device restrictions that are currently in place. Individual airlines have yet to come forward with any rule changes, however the FAA advisory committee is coming forward with a recommendation to ease those device restrictions. According to an AP report, the committee is expected to send their recommendation to the Federal Aviation Administration (FAA) on Monday.

LG aims for unified design and improved hardware in 2014

There has been a lot of talk lately from media and consumers alike about build quality and materials in their smartphones, tablets, and any other electronic device.

Amazon Trade-In Beta now Live, Trade that iPhone for some Andy

It looks like Amazon is joining the likes of Best Buy, T-Mobile and others and are now offering a full trade-in program. The Trade-In Beta was explained in a little more detail today and you can see the full press release below. It looks like Amazon will be accepting things like Electronics, Books, DVD's, Games and more all for the trade-in program. I like this idea as I have plenty of old games I don't need, not to mention that iPod Touch that I never use now I have a 32GB MicroSD in my Android phone, and Google Music Beta to top that if needed.

IOIO for Android detailed: Project samples from USB breakout board [Video]

We mentioned SparkFun's brilliant new IOIO for Android earlier this week, a USB I/O breakout board for Android smartphones which turns your handset into a super-Arduino of sorts. Now the brains behind the board, Ytai, has spilled the beans on the project, including some sample code and a handful of ideas that you can use IOIO to create. For instance, there's the Retroid, a smart alarm clock which can be told to make different ringing patterns and show various LEDs depending on incoming calls, messages and other events on the handset. Or the Visual Charger, a huge multi-segment LED power indicator which gives an at-a-glance idea of what percentage the smartphone's battery is at. [youtube 8sAvXCfEj3s] We prefer the Wall Printer, though, which uses seven Sharpie-style market pens hooked up to servos for an old-school printer effect controlled by an Android phone. Definitely worth considering if you're into Android and electronics; you can pre-order the IOIO for Android here, for $49.95. [youtube aYUMYyXBaF0] [via Twitter]

SparkFun IOIO for Android makes Arduino-style hacks simple

If you're familiar with the Arduino then SparkFun's new IOIO for Android should get you really excited. A straightforward way to get I/O from an Android 1.5+ device's USB connection, the IOIO board uses a simple Java API to hook into your app and then allows you to link external sensors, inputs and other controls with your own software and the capabilities of the Android device itself. Among the connectivity choices are Digital Input/Output, PWM, Analog Input, I2C, SPI and UARTcontrol. SparkFun have tested it with the T-Mobile G1, Google Nexus One and Nexus S, and Motorola's Droid X (along with an unspecified tablet) but it should play nicely with other Android devices too. The firmware is all open-source and no modifications are necessary to the handset itself, so you shouldn't impact your warranty. It's available for pre-order now, priced at $49.95. [via Twitter]
