My final product!

Wish everyone good luck for examinations! =)

A saw is a tool that uses a hard blade or wire with an abrasive edge to cut through softer materials.



There are different types of saws.

Crosscut
In woodworking, a cut made at (or near) a right angle to the direction of the grain of the workpiece. A crosscut saw is used to make this type of cut.

Rip cut
In woodworking, a cut made parallel to the direction of the grain of the workpiece. A rip saw is used to make this type of cut.

Plytooth
A circular saw blade with many small teeth designed for cutting plywood with minimal splintering.

Dado blade
A special type of circular saw blade used for making wide grooved cuts in wood so the edge of another piece of wood will fit into the groove to make a joint. Dado blades can make different width grooves by addition or removal of chipper blades of various widths between the outer dado blades. This first type is called a stacked dado blade. There is another type of dado blade capable of cutting variable width grooves. An adjustable dado utilizes a movable locking cam mechanism which causes the blade to wobble sideways more or less. This allows continuously variable groove width from the lower to upper design limits of the dado.

post abit about safety

Health and Safety in a workshop is very important. If a pupil/student uses equipment, tools and machinery, he/she should have received safety training. This should ensure that he/she feels confident in the use of machines and can operate them without having an accident or causing an accident to other people.

structures

bridges
Bridges are needed for a variety of reasons. Generally, they ‘bridge’ a gap between the banks of a river or they span the distance between two sides of a valley. They are made from materials including stone and steel. Bridges can carry people, cars, lorries, railways and even rivers.

tower
An art straw tower is a little more difficult to build compared to a model bridge. Towers can be all shapes and sizes but they must be designed carefully and drawn accurately. Basic tools such as a pair of scissors, sellotape, pencil, ruler, set squares, a T-sqaure, are required. With the bridge, a jig can be used to fold/bend the art straws accurately.

This is a scary looking toy isn't it? Is it suitable for kids?
Of course NO!

This shows a toy which his head is popped out, by don't know how. But if you were to give it to a baby, he or she will cry straight away. Kids saw this kind of toy would get frightened sometimes, some just throw it on the floor. Though the colours are attractive, due to the evil and scray face the toy shows, children will not like it.

True meaning of Design and Technology

BALLOONS. They are all so colourful and creative, with cartoon characters. These are mostly targeted at small kids. They love to play things like balloons and balls. In order to attract them, they make the balloons colourful.

This a white plastic kind of pencil case that mostly of boys that are age of 8-11 years old to use. It has the repeated design of monkey heads on it, that suits boys most, as girls do not really like monkeys.
Most primary school kids will then buy this kind of pencil case as you grow older, you do not want cartoons or pictures on your pencil case. If it is younger children, they would use a pencil case that is more of cartoons as they will think it is cute. Eg. is that, girls maybe like barbie dolls pictures on it, while boys like superman pictures on it, etc.

This is the window live messenger, which allows us not only to send emails to each other, but also chat with each other. This can also add friends that are using the yahoo messenger. It's uses are mostly like yahoo messenger but the design is abit nicer so people would rather choose window live messenger.
So this two messengers, many people chose window live messenger because of it's design. Though many people are using the window live messenger, there are still people using the yahoo messenger.

This is a pink sports watch. People designed watches to see the time. This pink watch is designed for girls as it has the colour pink. Most girls like the colour pink and the numbers are special to attract them.

A video on a mechanical toy. Mostly girls will like it because it has a design of a female mouse(minnie mouse).

Hi! Today I am introducing to you the 'donut keychains'.

This is a creative design that I think it is suitable for young girls. They have those eyes that make the donuts more realistic and cuter. With more colourful colours, they make them more attractive.

Young girls would normally hang them on their wallets or keys.

Hey, a week had passed and I'm back to post. Guess what?! DIGITAL CAMERA!
Why do we use digital camera? To take photos. We usually take photos when we go out as a family for some outings like picnics. But now, it is seldom for people to use digital cameras, though some are still using, as most of the people now take photos with their handphone, which has a technique of taking photos nowadays. But it is an useful object that had been invented.

Hi, lets look at some pictures I had researched on mechanical toys.


Metal mechanical toy (panda)


Wood mechanical toy (pig)


Metal clown toy


Wood toy train

Hi, back to post again. This time talking about MP3. MP3 and MP4 seem to be a very important object for teenagers and young adults now because going on streets, you can see many people taking it.

This is a MP3 created by 'CREATIVE'. As you know, it is an enlarged picture. The colours are bright and think most people do not really like bright red. I suggest that it can be just white.


It is great that someone in the world had created a small object that can stored a lot of songs and is easy to bring out. Songs make us relax so it is a very useful object.

This is Nokia phone 6288. It has a dimensions of 100 x 46 x 21 mm, volume of 91 cc and weight of 115 g. It has a 262,144-color display, which is 320 x 240 pixel.
Beside contacting with each other by calling, the phone has the ability of E-mailing client with attachments, MMS which has the OMA MMS 1.2 and Nokia Xpress audio messaging (AMS), which are very useful too.
Other than those that I mentioned, it also has 2 megapixel main camera and VGA camera for video call and video sharing. It has only 6MB of internal memory and can be extendable to 518MB.

It has bluetooth and infrared, which are useful when we want to send files to friends. Besides that, it also has games to play when you are bored. It has organiser which consists of alarm clock, stopwatch and etc. The talk time can be up to 4.5 hours (GSM) and 3.5 hours (WCDMA). The standby time is up to 280 hours.

Today taking about sony ericsson W910i. Nice right? My phone!

This handphone allows you to choose another song by flicking your wrist. It has the walkman player, which turns th phone into a powerful portable music device. We can even listen to audio books and access podcasts.
It has the sizes of 99 x 50 x 12 mm, 3.9 x 2.0 x 0.5 inches, weight of 86 g, 3.0 oz.n

It has a memory of 35MB, and can be extendable to 4GB. It has bluetooth that allows sending of files to your friends.
The screen is 240x320 pixel, 262,144-colour TFT. The talk time can last up to 9 hours and the standby time can be up to 350 hours.

This toy is made of mostly wood and cardboard. It is liked by small kids for their cute design. I think that the toy should be made by wood, instead of cardboard. This is to prevent waste of materials as they are not strong enough. Small kids often spoil their toys so it is best to make the toy with durable and hard material. I also think that the gears below should be covered as to prevent kids from putting their fingers there while turning.

It is best that a toy can be water-proof so that when they made it dirty, adults would be able to help them clean it. This can help by keeping them germ-free.

This is a toy mostly made up of wood. We can see that is has materials like rubber bands and metals.
It is quite dangerous because the rubber bands can break after a long period of time. Furthermore, it is not suitable for kids to play because they might hurt themselves with the rubber band by shooting each other. We can improve by using gears.
At the top of the toy is the blade thats looks like one on top of the helicopter that allows it to fly when control. But it is dangerous as the edge of it is sharp and long. We can improve by smoothen the edges.
Inside the toy we can see wires. It can be dangerous if kids play with them it can suddenly electricute them to death. A good suggestion is not showing the wires or anything dangerous outside, but to make it more real by using equipments like nails and hammer, and even more wood.
