Line Follower Robot

Last week I’ve just made a simple line following robot. So I want to share my experiences to you all. Especially electronic freaks and robot fans I say simple because it’s really so. Me and my friends (Setyo and Awal) just need 3 days total in building the robot.

Basically, just head to this page, it will help you with most of the basic theory needed for building the line follower. But I didn’t follow all the designs. I used a tank platform here. But it’s just a little difference in the mechanical design. The controller and everything’s just the same. But there are some schemes that will not work there. I’ll explain them and the way to debug.

First, the sensory scheme is not working with me. The receiver IRs won’t work. I dunno why. But I’ve made a little improvisation and it works. This is the scheme. Actually this is the sensory scheme from http://www.kmitl.ac.th.

Second, the program sourcecode will not work in Keil, so if you’re using Keil, you should compile this modified sourcecode.

If you do everything that is stated there and follow my debugging process, I think you’ll succeed.

Here is the pictures from my robot. His name’s Gugun

And here is the sensory circuit (it’s on the bottom of the robot)

Anyway, good luck to all of you who want to make this thing

Nowadays kids….

Wow! I’ve just got this image from my friend. This is a condition we encountered a few months ago when a music event is being held in ITB. He everlasted that condition and frame it to a good photo here.

What’s the uniqueness of this picture? Well, if you observe the relationship between their age and their fashion, you’ll get the unique point

Hmm,,, I wonder,,, is it i’m going old or kids are quick to mature (at least the style :D) nowadays…

What’s your opinion?

P.S.: the photo is taken by my buddy Setyo Adhi Vicaksono. He’s an upcoming photo maestro :). if you want to contact him, just call him at savmv@yahoo.com (4 Setyo: Here mate, I’ve fulfilled my promise :D)

Simple steps to disinfect Win32/Sality.s virus

I have some simple steps to disinfect this. Just read down below

Seems like this virus has attacked so many people around me right now. I’ve took an attack too last few days, and I got hit rather hard by it. This virus attacked .exe files by adding some more size and making stupid antiviruses think that it is a virus. So if your antivirus is bad, it might just delete the files and ka-boom! your windows will be crashed… And if you’ve got attacked by that virus and you want to install an antivirus to prevent that, the .exe files of the antivirus will be infected too. That way, these stupid antiviruses will close it’s own program. So basically you can’t install antiviruses. I searched the internet, but there isn’t any simple moves to get rid of that in there.

So last night me and my friend tried something simple and it worked! The virus couldn’t be taken out entirely but it became harmless. And future antiviruses could remove it completely.

Here’s the steps:

1. Take your infected hard drive out of your PC.

2. Go to someone who have the latest updated Kaspersky antivirus (AVG won’t work, and i haven’t try the others…)

3. Put your hard drive to his/her PC

4. Run his/her windows.

5. Scan your hard drive using his/her Kaspersky antivirus. You’ll find out that most of your .exe files have been infected.

6. Disinfect all of them

7. You will find that some files in your system32 couldn’t be disinfected. this is the core of the virus. get rid of them.

8. You will find that a file couldn’t be deleted. this is the main problem. i haven’t find out how to delete this. Just leave it alone

9. Copy the installer of the kaspersky from his/her computer.

10. Run your windows, install the kaspersky and update it to the latest version

11. VOILA!! your PC is safe now.

After this, the main virus will try to infect files again but it will be blocked by kaspersky. Ignore it now. I myself couldn’t do anything about the main virus. But it is harmless as kaspersky will block it’s movement. As far as i know, no antiviruses could kill the main virus. But if you know something, please tell me. Sorry if the information is outdated or worthless. I couldn’t find something this simple in the net. I just thought that some people would want to know this…

That’s all……

Indonesian Internet’s Being BLOCKED!!!

Oh my Gosh!!!

I’ve just realized that I can’t access rapidshare, myspace, and youtube anymore with the common way!!

This is insane! What happened to my country’s freedom of informations???

What’s after this? Wikipedia? Google? CNN?

My Goodness…. I just can’t say anything…

I felt like living in China or in a Talibanese country… Argh… Somebody please stop this madness…

Youtube, Myspace, and Rapidshare are not bad sites.. I wonder what they’re thinking. Those websites educate us and make everything easy to us to get informations and educations. What’re they thinking?…. Only because of one film…

Once again, the government makes us draw back into DARK AGE by doing something crazy like this.. Don’t they want a better Indonesia? Don’t they want better informations to make us clever?? We’re stopping informations when other countries gets them easily. When could we surpass them if things continues to be like this???

THIS IS NOT DEMOCRACY!!!

18 trillions rupiahs to fool people… I dunno… But I feel like something’s wrong…

God please be with us……

The greatest event of democracy in ITB

I’ve just go home from ITB. I’ve been watching the electoral counting to elect a President for “Keluarga Mahasiswa (KM) ITB” (I don’t know how to say those in English, maybe “Student’s Association”? I dunno ^_^). The thrill in that place is so great that I want to write now to share my experience.

The air was thick with spirits of change and the thrill to win the election. All elements of the campus are moving forward, with their own intentions and goals, with great spirit. The air was thick with competition. Just like the last election. ITB students are moving to succeed the greatest event of democracy in this year.

But what makes it great is that the candidates are competing with good sportivity. As far as I can see today, as the place is filled with strong compassions and desires to win, the place is filled with gladness too. I could still hear the laughter. I could still see the smile on everybody’s face. Very very democratic! I love my campus!

Well, maybe there are bad intentions and doing from all sides these days. But today I see nothing more than the eagerness to succeed the election. And it’s good.

Well, I’m just glad to see that democracy still live in this campus. Frankly, lately I’ve been worried with many bad rumors that this year’s election will not be as good as before, but now I know that the rumors were untrue. In fact, I see that maybe this election will be better than the previous ones. We all hope so, don’t we?

Hmmm, I think I’ve pushed myself to write too hard. It’s half past twelve in the evening, I’m so tired and yet I’m still typing. Now I’ve felt too tired. Maybe I’ll take a rest now. The counting is still in progress. Two candidates are running for each other just as I type. The difference is so little that I can’t even predict who will win. I’ll just say: Good luck. May the God be with us. May He show us the best way for us (ITB). Amen.

Oh, yes, I nearly forgot. There is a chance that a history will be written here today. From the three candidates who run for the election, there is a strong female candidate now. Maybe this is just common at other places, but in ITB, this is new. Never has a female candidate race with a male competitor to run for the top this tightly before. If she win, she will be the first female president of our student university. That’s a history. So there’s a chance that a history will be written here today, as the counting is still in progress.

Anyway, whoever wins takes the prize. It may be anybody. If somebody wins, then he/she is the best. All must accept that. Good luck for all candidates. May the best win!!!

Electrical Engineering ITB ‘81 –> compared with nowadays’ Electrical Engineering ITB…..

Wow! I’ve just known that Electrical Engineering ITB ‘81 has many great people inside! Especially great people on Information Technology! I felt rather shocked because all of them are young lecturers and researchers I admire for their intelligence and spirit!

Consider these names (correct me if I’m wrong, I apologize for any inaccuracy):

1. Bambang Riyanto -great AI figure
2. Onno W. Purbo - great IT figure
3. Budi Rahardjo - great IT figure (considered the best in information system security technology)
4. Armein Z.R. Langi - great Rural Communication figure, director of a research center in ITB
5. Suhono Harso Supangkat - Indonesia’s Ministry of Information and Communication Technology Expert Staff
6. Adi Indrayanto - great Neural Networks figure

Great, huh? Wow! I don’t know how it could be. Many great people comes from the same educational background from the same year. I can’t imagine the atmosphere when they studied back then. It could be so great to meet intelligent people every day back then. I felt so fascinated when I first read about these facts!

Well, maybe the greatness could be explained by one of them’s saying that said that at their times, that year’s students competed pridely with each other so hard that they never took the opportunity to cheat. It is shameful for them to cheat. Instead they struggled so hard. Pushing their limitations so hard so that they could overcome the others.

Hmmm, if I may compare their life back then with nowadays’ life, well, I feel ashamed of my year… Seems like the aura of competition and the ‘ITB-ean’ pride has gone,,

In my own year, it seems the world has turned upside down. What good becomes bad, what bad becomes good. In my year, cheating has become a COOL TREND!…

It seems so weird, but many people in my year acts like a hero, a great man who’s done something great and cool, acts like a superstar when they passed an exam without studying,, and sadly most of them are my best buddies…… And most of them told me that we who refuses to cheat are just simply stupid because everybody does it. Seems like there’s an opinion that we won’t become great people if we don’t cheat now. They always tell me that every Indonesian bureaucrate cheats. If they don’t, they will just become nothing….
I don’t know, maybe it’s just like what they said. Things change. What has become a pride becomes stupidity now. I don’t know. Maybe? But I don’t know what will happen to us when we graduates if we continue like this. Can we become what Indonesian people demand from ITB? A trouble-solver, not a trouble-maker?

I remember an old sayings that said that, “The lion only has it’s pride. If he lose it, he’ll become indifferent with a long-haired cat…”

They said that we (ITB people) were the people’s best hope. The people awaits our intelligent brains and skillful hands. But now we have lost our pride,,, the thing that differs us from the others,,, so how can they tell that we’re different from other people? If the best of us has been taken, how can we make something good?….

Well, I couldn’t write more. So many things I want to say. So many that they overload my head and just get stuck there and won’t come out. But, that’s all I want to say…

So hard to concentrate… final task… oh.. final task….

Oh man, it’s so hard to concentrate to do something these days….

I have to overcome the lazyness and start studying for the sake of my final task.. The clock is ticking fast and I’m going nowhere…
But, well, so many distractions lately.. blasted stuffs to do, stupid promises I have to fulfill, many fun things to do with my mates in this final year, damn… They’re just enough to break my concentration….

Oh well, I guess I’ll have to boost my spirit now..

Anybody knows how to concentrate, please tell me.. I’m close to dying now.. deadlines are coming….

Space Vector Modulation for Pulse Width Modulation (PWM) technique…

Guess it’s harder than I thought before

wept for a tyrant’s death???

the tyrant has gone, and surprisingly, everybody salutes him like a GOD! he gets a national-hero-funeral!! everybody wept for him.. everybody wanted him forgiven….

all i can say is:

WEPT FOR A TYRANT’S DEATH??? STUPID!!!!!

yeah, that’s what i mean

seems like everybody forgot how many mistakes he made and how he made us so stupid.. the “instant” culture, the habit of buying instead of making, etc.

seems like everybody forgot how many people he kill — he is a goddamn mass murderer for god’s sake!! (of course everybody in java adores him, he never kills javanese people… ask the outlanders and you’ll know how much they hate him…)

seems like everybody forgot how he made people outside java hates us javanese that much because of the stupid “javanization”… for example, ask papua people about freeport, and maybe you’ll understand…. how the rich island becomes poor but javanese people laughs in their fullness….

seems like everybody forgot how he made us this poor, by his stupid buildings using foreign loans….

i don’t know, maybe because we are so poorly stupid… so that Suharto may become the only tyrant in the world who doesn’t get punished or trialed after his regime falls……..

and because we are so stupid, so that we say “just forgive him, he has done much for this country too”.. what a crap!! his sins are just too many to just forgive him like that!!! i think his good is too little compared to his sins….

STUPID……

damn.. there are times when i wish i was not indonesian…

times like these…….

About the Ex-President (again)…

This is about our dying Ex-President (Soeharto) again…

This latter days when he’s sick, i saw many actresses, actors (although they’re most likely celebrities, they can’t barely act..) in infotainments who asks for forgiveness from people for Soeharto.

They said that the past is the past; We are a forgiving country, please forgive him; He’s nearly dying, so we should forgive him; He’s done many good things too to Indonesia; etc. It’s become a trend in the celebrity world to ask for forgiveness from him nowadays.

Whew.. Guess they know nothing but dressing, fashion, act like smart people and talk stupidly on the infotainment.

Have you known that everything that looks good back then was just a camouflage???

The building in our country back then, when big buildings are built, and many Indonesian praised Soeharto for building the country so he got the title “Bapak Pembangunan”… it’s money comes from rents from many countries, for god’s sake!

Fuel price was slightly cheaper than aqua in his regime?? It’s money comes from rents from many countries, for god’s sake!

The building of Jakarta, it’s money comes from other islands in Indonesia which riches were sucked for Jakarta.. Have the celebrities been thinking about the feelings of people outside Java? Will they forgive what Soeharto did to their islands back then? Many people wants to get separated from Indonesia because of that. Of the exploitation. For them, Soeharto have no difference with the Nederlands or Japanese who colonized us back then… He sucked hard and give nothing!

And he has many2 sins made from those buildings which many Indonesians still praise till now… Including the maybe-biggest-corruption in the world…..

Celebrities! Think before you talk!! You fool many Indonesians!!!!

Soeharto is the only mass murderer in the world whose life’s still fine after his regime falls! Other murderers like Pol Pot, Marcos, etc. had tasted the fairness of JUSTICE upon them. Soeharto? Haven’t. And probably never will. Cause this country is so stupid and it’s people easily distracted by stupid things like those infotainment………
