Spy Kit

WEEK FIVE

Hi!! How are you my readers?

Today in class apart from the summery of the laptops, we had to do a creative activity. This activity consisted of making a new invented in groups.

My partners and me have invented a new jewelry collection for spy women. It consists of a necklace with an incorporated videocamera. Also it has a pair of earrings which contains a microphone to be connected with your partner. The last complement is a bracelet that is used as a GPS (Global Positioning System).

Well, the other groups have presented another kind of objects, like a projector-watch. Or for example a pen with the ability of writing manually and then with a USB transforming the writing in a Word file.

See you soon!

Laptop Summery

WEEK FIVE

Hi!! Are you ok?

Today I will explain you something about laptops.

The first laptop was built in 1979 by William Moggridge of Grid Systems Corporation.
They are absolutely portables; moreover they don’t make so noise and use less power than PC.
Therefore, the disadvantages are that they are a little slower and have less graphics and sound processing power. Sometimes laptops are more expensive than PC or desktops.
Well, apart from this characteristics laptops and desktop have similarities. They have the same basic hardware, software and operating systems. The primary difference is how their components fit together. PC include a motherboard, video card, hard drive and other components in a large case. The monitor, keyboard, and other peripherals connect wirelessly or with cables. Whether the case sits vertically or horizontally, it has lots of space for add-in cards, cables and air circulation.
On the other hand, laptops are lighter than the compact tower of PC, and they have all the peripheral are in the same laptop inside of one frame. It is to say, that the keyboard and the screen, loudspeaker are in the same frame. Their little size let the user to put it away in wherever place, and transport to some place.
Some differences do that laptops are more expensive than PC. These are:
· Produce less heat than desktop components
· Conserve power
· Fit into a compact space

In the world of the technology we have a new vocabulary with acronyms like:

- CPU: Central Processing Unit
- GPU: Graphics Processing Unit
- LCD: Liquid Crystal Display
- USB: Universal Serial Bus

Nowadays in the market exist a new product called Whitebook. This is like an electronic notebook. However, it has more options than a only notebook. It is a mixed between a laptop and a notebook. I think is an electronic notebook with some parts of the laptop software.

Well I hope you find this explanation very instructive.

Textil Summery

WEEK FOUR

Hello my bloggers!!
How are you?

Today I have a summery about the textile of the future. Well, all this information you can find in youtube, this is the adress:

http://www.youtube.com/watch?v=bHLtZvbhn2Q&feature=related
Once a year designers, investigators, scientifics, etc. meet in a convention for showing their discovery in the textile world.
A new invention is a fabric that it doesn’t stain, it is to say, the fabric is made by waterproof fibers that impede that the liquid or the substance that cause the stain penetratre in the fabric. Although the substance is in the surface of the fabric the consumer can eliminate it wih water or a rag.
Moreover in a textil institute it has created a new fiber. It let apply technology in the fabrics. This fact let us utilize the fabrics in another fields. For example, this institute has put lights in a pillow, and for children who have fear to darkness it is interesting, because they can use it and not a normal light.
Some textile institutes investigate about fabrics that resist the traction, or the fire, or fabrics that they don’t skid.
In this institutes also use plastic for making new threads, and this form created new fabrics with new usage.

Well, here finish my summery, I hope you like it.

See you soon!

Materials Summery

WEEK FOUR

Hello!! How are you, bloggers?

Today I hang up the summery about materials that I said last week. It treat about plastic, metals and smart materials; polymorph.
PLASTICS
Plastics are important nowadays, since they are light materials and most of them are resistant. Well, plastics divide in two groups:
· Thermosetting plastics
· Thermoplastics
The thermosetting plastics cannot be reheated to soften or mould. On this way, it is impossible to recycle this kind of plastics. Some examples of thermosetting plastics are adhesive, melamine formaldehyde, polyester resins or paints or varnishes compose of polyurethane.
On the other hand, thermoplastic have the characteristic of they can be reheated. And we can reutilize it many times that the materials permit it to us. Then we can find it for example in schools like acrylic. Or for example we can find polythene in toys, bottles or bowls. Apart from this kind of plastic in this group, the thermoplastic, there is the PVC (polyvinil chloride) that with it we can made some things like water pipes, raincoats, long play records, coating on electrical wires and many more.

Well, not all are plastic nowdays. We can chose between more materials like metals. In this group we can find two subgroups:
· Ferreous
· Non-ferreous metals
In the group of ferreous metals, all of them contais iron. And this group have some properties than the other group haven’t got. Therefore, the group of non-ferreous metals haven’t got iron in their composition. Below I put examples with the ferreous metals with their components and their properties.
Mild Steel
Carbon 0.1 - 0.3%
Iron 99.9 - 99.7%
Tough. High tensile strength. Can be case hardened. Rusts very easily.
Most common metal used in school workshops. Used in general metal products and engineering.
Carbon Steel
Carbon 0.6 - 1.4%
Iron 99.4 - 98.6%
Tough. Can be hardened and tempered.
Cutting tools such as drills.
Stainless steel
Iron, nickel and chromium.
Tough, resistant to rust and stains.
Cutlery, medical instruments.
Cast iron
Carbon 2 - 6%
Iron 98 - 94%
Strong but brittle. Compressive strength very high.
Castings, manhole covers, engines.
Wrought iron
Almost 100% iron
Fibrous, tough, ductile, resistant to rusting.
Ornamental gates and railings. Not in much use today.

Moreover I put another examples with some non-ferreous metals.

Aluminium
Light grey
Aluminium 95%
Copper 4%
Manganese 1%
Ductile, soft, malleable, machines well. Very light.
Window frames, aircraft, kitchen ware.
Copper
Reddish brown
Not an alloy
Ductile, can be beaten into shape. Conducts electricity and heat.
Electrical wiring, tubing, kettles, bowls, pipes.
Brass
Yellow
Mixture of copper and zinc 65% - 35% most common ratio.
Hard. Casts and machines well. Surface tarnishes. Conducts electricity.
Parts for electrical fittings, ornaments.
Silver
Whitish grey
Mainly silver but alloyed with copper to give sterling silver.
Ductile, Malleable, solders, resists corrosion.
Jewellery, solder, ornaments.
Lead
Bluish grey
Not an alloy.
Soft, heavy, ductile, loses its shape under pressure.
Solders, pipes, batteries, roofing.

A courious material it is the pholymorph. It belong to thermoplastic group. It will be able to shaped and reshaped many times that we want. It is sold like a granules. For working in this plastic, we have to boil water since 62 degrees centigrade. Then the polymorph will form a mass and we will be able to work with this mass.
Well, this is all the explanation above materials. I hope you find it interesting my readers.

See you soon!

Missing the Bus

WEEK FOUR

Hello!! How are you , my readers??

Last Tuesday, I arrived something late to class, because I missed the bus. When I arrived to class my partners they were making a work. This consists on making a summary of the content of several pages Webs. When I finishes it next week, I will hang it here. Since it is part of the work, and you will be able to read it. Each career it will have a topic different from which will make a summary. My work tries on the materials that an industrial designer can use. Well, that is what we have made in the Class’ Practice.
Then, in the Practice of Laboratory, we were working again in “how a good oral presentation should be made”. This way, at the end of the course, when we make the oral presentation, we will make it better.
I want to write above last Wednesday, but I didn’t go to class because I was ill.
Well, next day, I will be able to go, and I will tell you more things above my English lessons.
Greetings

See you soon!
