Song playing is called " wish " by s.e.n.s. I choose this song because, it can help you to relax and help you think better. And to generate more ideas. XP and i personally love this song a lot. XD

hello, everyone...
have not post for a few days...
don't feel like posting... but then still must...
i don't want get low marks for my d&t... haha.
so post barhs... X))
few days ago, i realised that er...
what is mechanical toy... -.- i mean...
cam toy is not mechanical toy...
CAM is a kind of mechanisms used to make mechanical toys... or stuff -.-
aiyoyo... i write untill i also blur ler...
hmm... all mechanical toy is made up of one or more mechanisms...
and, CAM is not the ONLY mechanisms...
there are still many kinds of mechanisms...
example...
CAMS
CRANKS
GEARS
RATCHETS
LEVERS
PULLEYS
haha... and many more! these are only the most, basics and common... X)
okiie... you know what is CAM right...?
then... i will talk about... the others... (:
okiie... firstly... CRANKS...
Cranks are similar to a simple cam. They convert circular movement into a reciprocal one (up and down motion) or vice verse (down and up motion)

another picture... of a CRANK MECHANISM in a toy. haha...

OHNO... MY COM IS RUNNING OUT OF BATT! NEXT TIME THAN I CONTINUE!
T.T MY COM GOING SPOIL SOON! TEARS... =[[[
BYE~

hello everybody!!!!!! XDD
it've been 5 days ago since i blog! X)
hehe, cause im busy doing my journal... T.T
and till now, is still undone!!!!!!!!!!! =[
school reopenning soon! XD but, homework haven do finish! tears...
and mr soo haven reply my email!!!!!!! =[
sighs! nevermind! today gonna post... still about mechanical toy!
XDD very boring right? everyday cam toy... hahaX)
but then like that can understand more marhs! X))
below is a cam called Swash plate cams X)
haha. below is a simple example(:



haha(: let me show you another, but is more like a toy. ^^ using the part in the picture above to make this toy. X)

Dancing puppet


The mechanical display above is a dancing puppet. As the swash plate cam rotates, the two roller followers rise and fall. This motion makes the puppet look as if it is dancing / waving its arms.

My opinion about this toy: I think, the bottom part of the toy should be placed in a box, or covered. Maybe one that is transparent. Firstly for safety reason, because the young children might trap their own fingers in, and cause injuries(: and secondly why i think it should be transparent. Because it allows the children to be able to see how the toy work. And lastly, im very curious about how is this toy going to work. Can it move by itself? oO if there's some handle or something to make the Swash plate to move, that will be better... right? this plate won't possibly move by itself... haha. = =

haha. now, for another kind of cam.^^
its called flat plate cam/linear cam X)
the picture below is a basic flat cam.


As the flat plate cam profile moves to the left the follower moves up and down, matching the shape of the profile. The flat plate cam then reverses in the opposite direction and the follower drops and rises again.

A more sophisticated example of a flat plate / linear cam is shown below. The follower is unusual because it has a roller / wheel to help the smooth movement of the flat profile cam and follower. It also has a ‘return spring’ that pushes the follower against the profile, ensuring that it always runs against it and follows the shape precisely.


and now! i finally know how a mechanical paper punch work! X)
similar to those we use. SIMILAR, NOT SAME. haha X)

The edge of the flat plate cam can be shaped to give different vertical movements of the cam follower. Flat plate / linear cams are used frequently in machines that carry out the same repetitive movements.

weeee~ hmm, i think i've blog enough of different kinds of mechanical parts.
i think i should blog about something else! X)
haha! next time! X)) i go do my journal now! ^^
and oh yar, i have added in another song. called FORBIDDEN LOVE!
XDD I LOVE THAT SONG(: or rather, MUSIC. haha. ^^
and im running out of things to post soon...! T.T
haha, kayys! byebye! X))

hello! XD
as i had said i will be blogging more on different cam. X))
lets start with the different followers! XDD
There are a lot kind of followers. below are some of the examples(:

Flat face follower(:


Off set follower(:


Pointed follower(:


Roller follower(:


Although there are many kinds of follower, but they all slide or roll at the edge of the cam.
and then for the cam profile. XD

Heart shape cam
Heart shaped cams allow the follower to rise and fall with ‘uniform’ velocity.


Circular cam
Circular cams produces a smooth motion.


Pear cam
The follower will remain motionless for about half of the cycle of the cam and during the second half it rises and falls(:


The snail/ drop cam
Heart shaped and pear shaped cams generally allow for a slow rise and fall of the follower. However, a snail drop cam is used where the drop or fall of the follower must be sudden.


i will end here for today, next time continue again.
X)) BYEBYE!

hi everyone(:
today i'm going to blog about cam toys! ^^
firstly, if we are going to do, or write about cam toys.
we have to first understand what is cam toy about.
okay, firstly what is CAM?
A CAM has two parts, the FOLLOWER and the CAM PROFILE.
let me show a picture of the CAM. (:

the cam profile should be the red part.
there are many many kinds of CAM,
this is just a simple example of CAM.
next time i will blog about other kinds of CAM. (:
this kind of cam can be found in many mechanical toy.
this is a video of how it works.(:

wah, the teeth so white. haha.


an simple example, haha. did you see how it works?
the white small circle in the first picture should be attatch to a stick or something, and to the thing that u can turn it. Hmm, don't think you understand. haha. another picture here.(:

can see the " stick " im talking about? haha. (:
and, the white part below the person's leg in the picture(follower) is not attatched to the cam, (the red part)in the first picture.
Hmm, this is just how it works! X) roughly get the idea? XD

found something interesting in the net, but the picture cant move! T.T
is so cute! XD haha.


if it moves, the duckies head will go up and down! haha! so cute! XD
This is how it works! (: so cute right...? XDD

and when you pull the rope attatched to it, the wheels will move and the duckies heads will go up and down again! HAHAHA! ^^

SO FUNNY! XP
haha. thats all i think, if i carry on, i don't need sleep already. next time then i continue! ^^ byebye! XD

hello everybody... just found out that i've not been blogging for quite a long time... because im really busy this few days. REALLY BUSY. and i don't even have the time to do my journal... okiie... im blogging about today's d&t lesson. is not really about d&t, but is linked to d&t, haha. we learnt to use the tablet pc today, and is really fun. haha(X hehe. we learnt to use the " pen " from the pc, and use it directly on the screen. and the worst thing is, only 6 people in our class turned up... we learnt to use the " pen " for microsoft word and powerpoint, and art rage. the most fun is art rage! X) hehe. coz can draw... just like normal drawing... cause we are using something like pen. haha. at first im a bit blured, but after that im not that blured... at least i learnt something today! X) we also used it to draw a cam toy. X) haha. then mr soo also said that next year we will use tablet pc to do our assignment too. ^^ haha. i love it. although what i draw isnt that nice, but at least is something new and interesting. so lessons will not be that boring... ^^ haha. okiie... now, blog about something else...
i realised that, i think we are not making those kind of mechanical toy... the mechanical toys i talk about in the previous post. except for the caterpillar toy. what we are suppose to do is do about a cam toy, that looks something like this.
the tiger and lion cam toy

this is a picture found on the net. looks cute right?
whale cam toy

i think we are suppose to do something like that, not just any mechanical toy.
im so sorry to give the wrong imformation. x(( sighs... but nevermind, now i know! ^^ but, IM STILL NOT SURE! MR SOO!!!!!!!!!~ WHAT SHOULD I DO !? ARE WE DOING A CAM TOY, OR JUST ANY MECHANICAL TOY AS LONG AS IT CAN MOVE? OMG. I DON'T KNOW WHAT TO DO. AND WE HAVE TO DO THE ACTUAL THING OUT RIGHT? =[[ im not sure, anyway. i will continue the next time. i got to go sleep now... X) byebye! XD

hello, i don't really know what to blog about.
But since we are going to do the journal about mechanical toy...
then i shall blog about it... haha. XD
so, i can also understand more about the mechanical toy...
and is also related to d&t. XD
okiie, an introduction of mechanical toy.
mechanical toy
There are many kinds of mechanical toys, but what exactly are they?
XD according to what i read in the net,
mechanical toys are toys that moves, that are powered by mechanical energy,
for example using rubber bands, gears, springs, pulleys, lever and etc.
okiie, im still a little blur... = =
let me show you some pictures from the net.
The caterpillar toy(:

the caterpillar will move when you turn the wheel and axle at the side.
Mechanical drum toy

this toy work when the cart is pulled along, and the small square-shaped pieces of wood mounted on the wheels’ axle flick the ends of the drumsticks, causing them to beat the drum.
Rubber band gun

haha. i think i play before this kind of thing when i was young...
althought looks dangerous... haha. But fun for a child. XD
I'm not sure if this is a mechanical toy... i think so?
it moves right? i think so. XD
Merry go round!

haha, i like this the most... XDD is a metallic mechanical toy?
what is metallic?
it is of a metal element being in the free or uncombined state: metallic iron.
i don't know how it works... but i like! haha.
okiie, enough pictures. or else my post will be very long... XD
haha. okiie, get a rough idea of mechanical toy!? XD
i hope so... haha. okiie, go do my journal now... ^^
byebye! XDD
