Dell to Build Android Phone for AT&T
According to a Wall Street Journal report, Dell Inc is planning to launch a smartphone with Google’s Android mobile software on carrier AT&T’s network, which will be launched as early as 2010.
According to the report, the phone will be similar to Apple Inc.’s iPhone, having a touch screen instead of a keypad as well as a tiny camera. Dell’s AT&T phone is similar to a device Dell showed in China in August, but has some different features.
By launching the phone for AT&T’s network, Dell’s would make its first jump into the competitive U.S. cellphone market. There is news circulating that Dell is also in discussions about offering the Android device on other U.S. carriers.
Top 7 Water Powered Calculators Running on H20 Batteries
Water Powered Calculators and other devices have been around for quite some time now. Practical or not, these devices have been selling quite well as novelty products and business around the world have come up with innovative ideas and designs for them. I thought, It would be a great idea to make a list of all water powered calculators available in market. I did and then selected the top five of them for our readers. It has been a great 2 hour journey full of discovery and learning.
How does water powered calculator work?
Generally Two different metals have difference in electronegative charge. If we immerse them both in a fluid which has free floating ions (not pure water) then one metal electrode will preferentially attract ions causing a potential difference. If these metals are connected to an external circuit the process will create a very tiny amount of current in micro-amps range(Most calculator chips only require one or two micro-amps to operate). The process will run perpetually as the metal will continue to draw more ions from the solution until the fluid is exhausted or metal is fully oxidized. ( similar to a lemon battery)
The water is in fact not the source of the power. The electricity is produced by the difference in electrode potentials of the anode and the cathode which are inserted into the water (or potato/lemon). It’s just a battery, it looks a little bit different, but the clock draws a very small amount of current anyway. So in other words: the water powered calculators are actually powered by a dissolving of metals like zinc.
EMC’s Water Powered Calculator
This one is most elegantly designed calculator. It has a futuristic shape. looks like an alien on your desktop. can only be ordered in bulk and you can get your logo/name printed on it. min order qty is 25 and will cost you around 15 British pounds each. You can request a free sample here. It indeed makes a great business gift. Although I hate the small keys, over all it’s the best around. More Details here
Top 5 Gadgets of this Week
A new week and we are here with another cool list of top 5 gadgets that we found interesting. but first thank you very much for your great response and interest in the previous list we published last week. I would not like to stand between you and the list anymore.. here you go..
Stealth Sound Amplifier
This looks like just another person with a Blue tooth headphone attached to his ears. Beware, this is not an expensive looking cell phone headset. It is a Stealth Sound Amplifier that will let him hear whispers even up to 50 ft. away. Read the rest of this entry
