A big demand for the world's cheapest Tablet

Since December 14, the manufacturer data Wind took up the advance bookings for the world's cheapest surf board, Aakash, in India. In just two weeks, it has received 1.4 million pre-orders.

Today the tablet costs around $43, but the idea is that the price will eventually be pushed down to $37 and then to only $10 (!).

Aakash has a 7-inch screen and runs on Android 2.2. Under the hood sits 256 megabytes of memory and an ARM 11 processor. Apps are not downloadable via Android market place but through Getjar.

Wind data now make up reservations for an upgraded version called Ubislate 7 that is expected to be released in March later this year. To manage the production, it will launch three new factories in 2012.

- We plan to produce 75,000 units per month from April, said a spokeswoman for the company to Physorg.com.

Dell XPS 13 - The ultra book to keep your eyes on

Ultra Book laptops looks to be, to say the least populated in 2012. Dell has announced its contribution, XPS 13, which promises to be one of the smallest computers ever created.

XPS 13 is composed of a frame in carbon fiber and an aluminum shell. Performance-wise the computer while arrive with a few options available, both Intel Corie I3, I5 and I7 are selectable as processors.

With a mouse pad made of glass (!), backlit keyboard, and a matte screen, seeing it on paper it seems as if Dell has found the right formula. How it stands up to the competition, we obviously will see later, but right now, the XPS 13 appears to be an ultra book to keep your eyes on.

The Dell XPS 13 will be released in March 2012, albeit at a still unknown price.

Question of the day: What thermostat is best for me?

I got this great question in the mail today. It read like this:


We live in a house with direct electric heating. The radiators are two-phase oil-filled from the eighties and thermostats, in other words not quite tiptop.

We are thinking about installing a heat pump and a wood stove meaning that the direct-acting electricity is just there for the top and maybe to heat the parts of the house where the heat pump can not reach.

My question therefore is: Can anyone recommend a good thermostats with central control or room control for our direct electricity? I think cables are ugly, so I want as little wiring as possible, preferably wireless.

My options today is the BAS EVS from Bonab, but it has the disadvantage that it regulates the heart of the house and therefore almost certainly miss the heat pump is not "access" everywhere. Wireless options I have found can not handle two-phase, but there may be others I missed?

Answer: I think there are many different thermostats that would suite you well. For example, check out the Honeywell RTH7600D. I am sure it will not let you down.

A couple of facts about thermostats

A thermostat is a control technical equipment that will maintain a nearly constant temperature in an order.
The simple electrical thermostat consists of a bi-metal-feather that act as switches by the bend differently at different temperatures.The actual connection of the circuit is often done using a relay, to avoid sparking.

Thermostats can also occur in other contexts, such as hydronic heating system and in the shower, where they can be a Earwax,which by their expansion can close and open a pipeline openings.
Some alloys are magnetic at a certain temperature, curie point, but becomes non-magnetic above this temperature.
This featurecan be used for thermostats. A practical application, temperature maintenance of electric soldering irons.
The brain's hypothalamus, there is also a biochemical function thermostat that regulates body temperature.
Many thermostats today are really clever and uses wi-fi technology to it's advantge, for example check out the Lux tx9000ts.
