Solar charging case for iPhone

Published by admin under Gadget & Technology

An iPhone case that comes equipped with a solar cell which soaks up sun juice to charge your iPhone is definitely a great idea. The solar charging case from Brando is just what we’re talking about here which keeps your iPhone juiced up in the green and handy way.

The case provides protection to your iPhone from scratches and smudges. And the most important is while you clip the case on your belt with the iPhone inserted in it, and you’re exposed to sunlights, the case will start collecting sun juice and charging its internal battery, which can be used to power up your iPhone later.

The solar charging case is specially designed to suit both iPhone 2G and 3G. It comes in a flip-top and a side-open design. The case takes 3 hours to get to its full charge while exposed directly to sunlights. Just spend $48.00, get it from Brando, and it’ll be yours, to let you keep your iPhone with sufficient juice always.

Brainwave Headset - No Needs Batteries
Researchers have developed a set of brainwave reading headphones, which needs no batteries to make it run. The function of this headset is simply to be worn by user so it can continuously monitor the user’s brainwave. The headset needs NO battery as it’s powered by the body heat and sunlight. The headset is actually a portable electroencephalogram (EEG) device that is made to resemble a set of headphones. Which makes it not looking too weird while the user is wearing it on the head. The headset is meant for seizure patients, remote monitoring them whether they’re under certain stressed conditions. Or it can be used as input devices for computer games that allow you to control the game play with your mind. Basically, the headset needs about 0.8mW of electricity in order to detect precisely the brain wave signal. The headset is designed either powered by solar energy or by the body heat. And the total power generated by any of these methods is about 1 mW, which is more than enough to get it to detect brainwave accurately and send to the receiver. Some other great use would be using it to detect brain activity when a wearer is sleeping, which could lead to a better understanding and subsequently improve the quality of sleep of the wearer etc. [...]
