PMR Results...
Next day, awakened by a phone ring... It was about 10.15 And you know what? Some already reached there! I was like... what the..? The results will be announced by 11am, and the're just so early! I don't know why, I not feeling like getting my results. Watched TV till 10.30 then played a game of Red Alert (Easy enemy with superweapons on only la), then we shoot off. The area was congested like... Don't worry, my father went for double parking, (Cause others already double parked and arranged till like... so straight! Haha.. If MBPJ come and write ar saman, they will earn big money...) I actually went in first... I headed straight to hall and it's really really a mess! So many people's around and so noisy and.... bla... bla... bla... I saw my classmates (Thanks to Sathya, eventually I saw Sathya first, he is tall enough to let me see between heads, haha...) So I headed straight there, then there comes lin... "Everyone took dy... You got straight la...", I was like... "What?". (At first I thought she was too happy until mad dy, jumping here and there haha... Cause she got over her BM...) Well, still got quite a lot of people not yet take their results, managed to squeze through them... Then one by one, saw them laughed, screamed (I don't know normal mic can take their extreme-high frequency or not), hugged, cheered... Nah, it just looks never ending... And those are more to girls ok? Cause most guys dy taken earlier. Lol... I was asking nearly every guy that passed by and was like all got straight! And I am the one that still don't know my result... (But aother few people did noted me that I got straight... zzz...) Then it was my turn, teacher just flipped through the papers and found my name... Well... Teoh Jia Xian... That's my name... (And did she purposely cover the grades part?), she handle the piece of paper to me... I straight away look at the bottom of the paper... "A!"... Wah... the feeling was... "mixed feelings"... Happy, relieved, (A bit disappointed with my expectations, as I expect BCina bye bye..." Haha... After my father knew my results he's like going to pavillion... Then... I think he talked to the phone about half an hour I think... But certanly it was not about constructions... I wandered around with Sui Wu... Haha... Well, some cried, some smile, some hug like... Some... Hold on... Some is queuing to buy exercise books at book store! Haha... Walau... Just took result then so fast prepare to go F 4 meh, don't scare me le... Went to the board section to see my sis next year class... Quite angry to see my sis in balau altough she got 5/7A's lo... Cause I got 7 last time and was in Jati!!! Haha... Then... Then nothing dy la... Go back la... Then sms like... Credit from RM15+ cut till left RM5. Haha...
Hmm, actually this is just parts of life.... Like what one of my friend said to me: "Straight A's or not we still need to continue our life..." If not mistaken. Yup... Its a point, (low or high doesn't matter) of life. Its not a point that makes you stops, nor a point that makes you end your life (Like a UPSR girl did so). Just take this point as reference, to advance forward. And, media did emphasis much on great and highly graded student, but remember, the student getting "E" for this year is still increasing... They do need our help too... As a friend thats caring, we are needed to play our role in society too... (What am I talking bout? Lol...)
Anyway, choz...

A toast for christmas!
Ok... Where should I start... Toaster huh? Have some picture of it first... Its a small one, very small one... Cornell CTO-2 oven.
So what's my aim? The main thing that does not function is the heater... Cause I actually done the testing and the light lit up for every wire except after passing through the heating element. And thus shows the only reason for this seldom used oven to slip in spoiled condition.
Heating element is inside some parallel holed metal casing. Its located above and below the tray.
So... Opened some screws and finally found a Torx screw that is impossible to be removed by normal screwdrivers... Had no choice and guess what I did...
It's not easy to bend it ok, I took nearly 20 minutes just to bend the cover... As it is hooked to the housing (You can see something sticking out from the removed cover)... Sharp edges nearly cut my fingers...
Inside view... Green-Yellow wire to the housing to ground off... Brown wire to the timer and output to the temperature "controller" and using yellow wire towards the heating element. It's connected in series and the electric flow through the second element which is located below and then connected to the neutral wire...
A view from another side that proves the series circuit theory.
The heating element seems nice with cover, but not without it... It's just a thin-twisted nichrome wire messing around...
So what I got from this oven is... The timer, which can hold function up to 15 min, a plug with fuse of course, and another free heating element, i don't know when i will use this again, but just keep it somewhere... Lol...
Hey, late dy wei, A 1994 Seagate hard disk from a old laptop coming up for next post, if possible...

Canon S200SPx Printer "project" report + other related topics... Lol!
Hey, don't look down on this print head, it cost nearly a new printer's price!
Feeling like switching topic pula... Lol... Life is quite busy for me nowadays... With robotics going on... And if you can come... Meet us (Joel, Andrew and me!) at PWTC 27-29... IF we cannot make it through elementary game then 27th is the first and the last day la... Lol...
Okay, back to the title... Hmm... You curious? I don't think people will be interested in this, but for me its fun! Dismantle this and that (Although sometimes you will break some so called "tabs" and "clips") does makes you think. Especially those screwless ones'... But I just can't take my hands out of it... And I love it... Lol... Any electronics you wanna dump? Give me first... Don't waste. Let me do some small "research" then go ahead and throw... Haha... I accept nearly all electronics la, but preferably complicated ones like players, phones, Hi-Fi, computers, printers, modems, speakers, even microphones! XD... Still remembered I got electroculated when repairing my small little night light (Or so called Cat-eye light)... I think it shocked me 3 times (No earth wire connected)... But I thought it was fun! Lol... Then another time I was trying to connect 240V directly to a hair dryer motor... Then you know what happen? A deafening loud "pop" sound and the RCB tripped. Smart? Anyway, the motor still functions well until today... Still using it as my computer CPU fan... Haha... These 2 "first times" did arouse my interest into this (although it's failures) Lol... Then the first electronics that I managed to repair from "hang" till usable is 2 VCD players... (Believe it, its not only computers that "hang"s) Just by changing a rubber ring... I think I could charge RM55 for that... The ring only costed about RM2, so count RM 3 profit from this, and service charge Rm50 (standard price for technician that provides door to door service)... Haha... And that 2 VCD players faced the same problem... So I managed to have one which is 7 years old in my room! (Last time thought it will cost much to repair, so just got a new one which is Bellcorp) At that time this Thomson player cost about 600+... Now you can even get a DVD player for RM98... Tesco Orbitz brand if not mistaken... Lol... So now you can see the technology gap is so obvious at that time.
Enough of the first experience. Haha. Have some angle-views for my printer first...
Frontal View
View from the back
This few shot is the easiest shot of all... Just place there and adjust some lighting... And Snap! Well, it took about 15 minutes to open the cover. To unscrew the adaptor screw and i spent the most time in figuring out how it holds the printer cover without any screw. Finally, I saw a 2 tabs at the side! After 2 cracks for each side it finally revealled it's metal body... (With the plastic stand below of course...) Took me a hard time to opened it without forcing it hard... Then I came to here...
Frontal View
Now we can have a very clear view of the belt, the roller, the print head, and a metal bar that supports the print head.
Back View
Here we have the motors to move the print head around and motors to power the gears and "slrrp" the paper into the printing zone, a circuit board that consist of many IC's, capasitors, transistors, (And whatever about electronics in KH)... Lol... A white "data" wire connected to the print head sticking out to its output (Print head) and a horizontal bar that moves and helps the mechanisms to "slrrp" the paper too. The box below with a wire sticking out is an adapter.
Back-Left View (As it's not clear in the "Back View" picture)
A clearer view of motors that functions to move the position of the print head or belt. By understanding the gears mechanisms, we can know the actua process when a printer "slrrps" its paper in for some inking... Lol...
Erm, Nothing wrong with your eyes, it's the same picture again with 2 red circles in it. The circle above explains how it moves the paper into the printing area. Note that the bar fixed on the right in the circle is springed. So when the printer is ready to print, it will move the gears in the red circle and the "floating" part of the circle will be off the bar and the bar will springed up and the 2 roller motors hidden inside the paper loading zone will does it job by pushing the paper into the printing area. That's why it's quite noisy when it starts sticking its paper into printing. The noise was quite annoying some times. Know why this printer doesn't push back the paper into the paper loading zone eventhough the paper jammed inside the printing area. This is becaue of the circle below of the picture. The black tab that is springed will stop the gears from rolling in the wrong way. The spring will extend if someone tends to pull the paper out from the paper loading zone when its stuck. the spring will absorb the force so that gears won get easily inpositioned and later damaging the printer. Thats why the printer will try to push the paper out of its mouth everyime it encounters error.
Back-Right View (As I can't image on the same "Back View" picture)
Center View
The black bar running across with 2 grey rubber helps pushes the paper in.
Ok... Lets get started...
This picture syok sendiri one la, Lol... Lets move on and get serious... XD
Okay... Starting from the top front... Hmm... Lets take out the print head and get the belt out of the way.
On the right edge of the printer
The bigger circle in the picture (Look carefully, there's a red circle) provides clean up for the print head everytime it does a row of printing and for the smaller circle which is more towards the right, this is the place where the print head stands by to wait for document or to provide absorption for ink during cleaning process.
Right edge of the printer (Below)
The sponge beside the gears provides a medium for ink to flow down towards an ink waste storage which is located at the below of the printer. So when a cleaning process is run, the contaminated ink will flow towards the "waste station" to be absorbed.
Forgot to mention... The waste station can be seen as a sponge like foam below the print head allocation area. So it will directly flow down to the drainage without overflowing the sponge above the print head. Thus allowing the print head to be cleaned neatly.
A closer and clearer view of the absorbent foam
Notice that the foam has 2 layers. It only managed to ink 3 quarter of the below one as I only used the printer for a year. At the right of the drain seems clogged as the ink doesn't have enough time to be absorbed into the foam before it dries up. The foam gives a spongy feel and when you touch the inked part surface, your fingers will be stained with some thin dry black powder. I suppose that it undergoes a long process of evaporation of those ink over here.
Parts of my finger already stained with the powder (The skin near my finger nail)
To test the absorption rate of the foam, I tested it with normal water (The can is just for illustration purposes) Lol... After i pour about 10ml of water onto the foam, I pressed on the spot, and guess what happened...
The result of this experiment tells us that the absorption rate for this foam is ultra fast. (Eventhough my fingers got wet a little) The water doesn't got repelled again. At first I thought it was a normal sponged foam. It evaporates quite fast for the first layer as the next day I got the spot quite dry compared to normal foam. The first layer absorbs quite a lot of water as the second layer only managed to got wet a little. The layer also has another properties that it only ensures one way flow. Meaning if some liquid enters the foam it won't manage to come out again. (Okay, I am not doing commercials about those pampers or whatever thingy, cause I don't expect this foam to absorb 6 cups of water... Lol...) This unique characteristics plays an important role in making sure that the ink doesn't setrains back to the sponge then towards the surface of the print head to ensure best printing qualities. I was prettily astonished. I think maybe someday I could use this foam to wipe over spilled water... Hassle free and best of it is... Disposable... Haha... Easy and cheap... (Should be cheap gua...)
Ok, now we should go back to the body of the printer... Here's the part below the printer.
Note that there is a black rubber roller sandwiched between 2 black plastics. Below the roller of the top, on the left of those white gears. This bar helps to "slrrp" the paper in to the printing zone then loads it out to its mouth.
Very suprisingly, I found this bar (the above picture), useful to me. I was thinking about maybe I can use that in robotics. Cause it produces well friction between gears and the bar or roller or whatever you call it. I will see what I do... Lol... Need some crazy ideas...
After dismantling the bar (Nearly broke the edge), found something that I was always saw in my HP printer. Those thread like thingy... Its a super fine thread taped on the exit of the paper. I still have no idea about it until now... Suggest some in my chatbox... Remember, it is always placed at where it could make contact with the paper.
Now gotta fix back the cover to the body again...
Main cover without any parts...
Internal view of the printer without cover...
Fixing the printer back to its original state
Among the things that I gained from this printer... Lets see... Hmm... A kinda cool USB cable which I had used for 3 printers... XD... An AC cable, a simultaneous 240V to 24V and 5V adaptor, 2 simultaneous 24V and 5V powered motors, and the roller/bar or whatever you named it. P.S. The blue-yellow and green screw drivers' were misplaced... Haha... Anyway, thanks to them...
So now the S200SPx printer already made a farewell with me for another time... Maybe its already recycled into a new Canon printer... And of course, farewell to a year old HP PSC 1510... Perhaps now it's wandering in the HP office now...
And say "Hi!" to my new print mate! Welcoming HP OfficeJet 5610!
I think thats too much for a post la... Perhaps some already yawning or fell asleep when reading this... Haha... Anyway... The printer is working well till now... Wah... Late dy le... Gotta go man... Tata...

Fish Fight!
So... Hmm... After completed my robotic registration, I felt really tired... So I went to living room and sit on the chair... Suddenly, that 2 tiger fish caught on a fight again. Since I have my camera near me, I just grabbed it and took this video... Have a look...
Nah... Don't worry about those 2 fish, cause they had fight and fight again since I put them into aquarium. Anyway, I still didn't see the situation like "menang jadi arang, kalah jadi abu" before... Lol... (though it had cause my 3 goldfish to say bye bye). So I separated them from goldfish, clown fish (maybe its a freshwater "clown fish", lol) and my "rectangle fish" (Since i don't know the name... It's the fish with orange striped on it's body)... So... I think that's all... Haha... Maybe it's not a fight after all... they're just "mencungkil bakat'ing'" each others! And it could be fun seeing them fight!

13 WORLD'S CREEPIEST PLACES... Interesting?
1) Bhangarh, India
India's Bhangarh, in the Rajasthan region north of Jaipur, is a town with a mysterious history. Built in the 1630s, it was abruptly abandoned ten years later for reasons that are still unclear. Legend has it that after a convoluted series of events involving a princess and a jar of enchanted oil, a massacre occurred and the town was never repopulated. Nowadays there are tourists aplenty by day, but no one stays at night. This might have something to do with the supposed curse placed on the town by a jealous shaman. Even the local archeological office is located half a mile away (better safe than sorry). But the magnificent ruins—not to mention the Palace of Prostitutes—imply that Bhangarh was something of a Gomorrah of extravagant goings-on. Perhaps that history—and not the ghost stories—is why a sign at the entrance reads, "Staying here after sunset is strictly prohibited." Either way, we're happy to rest our heads at the ultra-luxe Amanbagh resort six miles away.A ship ripped neatly in half offers a perfect cutaway view of life and death on the high seas. Everything is encrusted with barnacles, from cabins and boiler rooms to onboard assault tanks and airplanes. Much of the Japanese Navy's WWII fleet lies in the shallow Truk Lagoon in a volcanic valley in Micronesia, part of the Caroline Islands 3,200 miles southwest of Hawaii. Now a deep-blue diver's paradise (it was the subject of a Jacques Cousteau documentary in 1971), this was where the Allies sunk more than 60 battleships and aircraft carriers in 1944, many going down with their crews trapped inside. While swimming through the wrecks, you can spot gas masks, sake cups, and the odd "human remain." The ships are corroding fast and many have become full-fledged coral reefs, but they still provide a jaw-dropping testimony to the ravages of war. Tour companies, including the Blue Lagoon Dive Shop, offer excursions for experienced divers.
As your boat pushes out into the swamp by torchlight, ancient cypress trees and Spanish moss drape across the water. That far-off howl you hear might just be the rou-ga-rou, the Cajun version of the Wolfman. The Manchac Swamp, a.k.a. the "haunted swamp," near New Orleans is a Southern Gothic fan's dream. An imprisoned voodoo queen is said to have cast a curse on these watery surroundings around the turn of the last century, resulting in the disappearance of three hamlets in a hurricane in 1915. The occasional corpse still surfaces in this otherwise untouched bird sanctuary, left alone by commercial development for more than 100 years. Torchlit nighttime boat tours are offered by the Old River Plantation Adventure. But beware: As anyone who has spent a night in the wild can tell you, nature can be anything but gentle, and the staring red-eyed alligators can give you a real fright as they watch your boat cruise slowly by.
Wah... Lets have a trip there! House that never finish builded for 38 Years!! Staircases to ceilings! Ok, Its a design that no one had ever predicted! Ok, now get the cement wall behind the door! Hey you! I want the bricks arranged in multiples of 13! Haha...
Hidden below Edinburgh's medieval Old Town is a series of subterranean streets with an unsavory past. Mary King's Close is where plague victims were quarantined and left to die in the 17th century, and paranormal activity abounds down there. You might, for instance, feel some gentle tugging at your hands and legs by an unseen force. The cause is believed to be the ghost of Annie, a young girl abandoned by her parents in 1645. More than a hundred years later, in classic horror-tale fashion, a grand new building was constructed over Mary King's Close, leaving the streets, including the plague ghosts, intact underground. In 2003, the surprisingly well-preserved Close was opened to visitors, drawn by tales of its supernatural goings-on. Tour guides will accompany you down a stone staircase to the vaultlike, oppressive lanes. In addition to Annie's Room, there are typical re-creations of bygone lifestyles and plague deaths. Just remember to keep on moving, especially when you feel a sudden chill.
