My 1st PCB

Lately I've been busy with my java, battle of the band practice, and also my 1st PCB!!

I've always wanted to do something electronics, but I'm just not motivated. But this time, I have to do no matter what, 'cause it is my assignment(3 degree-of-freedom robot arm) hence, my 1st PCB is born.

In this entry, I would like to share how I made it.

1st: I draw my circuit design, using Traxmaker.


2nd: Print it out using LASER printer, and GLOSSY paper. Prepare a PCB board, FR4, and cut it to my desired size.


3: And then iron the print-out to the FR4.



Too bad my ironing skill's not good, some carbon didn't stick to the FR4, so I had to use the permanent marker to cover the copper which I don't want it to be washed out.


4th: Pour the Ferric Chloride power into a pale of water. Make sure the plastic pale used is thick enough, and everything used here must be plastic. The chemical will 'eat' the metal.


5th: Done. Well not really done, I still have to sand down the carbon which sticked on the PCB board, drill holes on it, solder the electronic components and what not then only consider done.


Thanks to Yeo for technical and tools support. LOL.

It's Not Right

Shin's having ITP, staying at Masjid Tanah, now.
Fungi's had to practise drum, staying at Masjid Tanah, now.
Yeo's going to KL tomorrow, staying at Paya Mengkuang, now.
It's 4.30am, everyone's sleeping, now.


I'm the only, and lonely, in the night.

I hate it.

I'm Sick

As stated in title, I'm sick, again. :(

Toothpaste Doesn't Work

Last time I went swimming I used saliva to antifog and it lasted for quite a certain period. But Von and Jenn told me to use toothpaste, so I tried. ( Actually I knew but forgot to do that last time. )

jenn: use colgate leh -.-"

vonne: ya lo.. use colgate or any anti tear drop shampoo will do... of coz if u wanna save money, use saliva

But the toothpaste-to-antifog doesn't work as well. Better than saliva a BIT though. Perhaps I should try anti tear drop shampoo next time.

Anyone can lend me? I don't use baby shampoo by the way. :D

( P/S: I used x-branded toothpate. Must it be COLGATE? Cannot Darlie or whatnot? )

Sometimes I Feel Like

Swimming lohx ~~

Just now went swimming with Fungi and YinYeo. YinYEO!!!!
What a guest.

Swimming is really fun.

For those who swims before definitely know that goggle will have fog inside it after a certain period. Yeo and I had came across to a solution for this from internet, that is spilt your saliva in the goggle, spread it with your finger, and rinse it with water. That should settle the fog problem for like 30mins.

So, when we were swimming, we wanted to try if the solution works. However, when Yeo spilt his saliva in the goggle, there was a girl beside him starring at him, with a WTF look on her face.

It was real funny! The expression on the girl was like seeing something really weird. lol.

So who wanna join for the next swimming session? :)

( p/s: I know there is anti-fog goggle, and mine' s is one. But since it's used for so many times, hence the anti-fog oil is no more on the surface anymore. That's why we used saliva. hahaha. )

Transformer

Watched with my bro just now.

We didn't buy the ticket earlier and we just went there to check out our luck, to see if there are any more seats for us. Lucky us! We got a double seat aka couple seat. lol. The cinema was almost full. Only double seats and 1st row seats available. Hmm, of course choose double seat la hor? hehehe

And as for the movie, not bad, not great either. I love the graphics, but you know la, transformers, story line.... hmm.... errr.....

A must watch movie for Robotics students. =p

Bye Bye Dr.Gan

Muahaha finished all my math subject in the engineering course, and the good news is of course as stated above.

No more Dr. Gan's class. Nightmare.

:D
