I’m not Jobless

noreply@blogger.com (Mas Tian) — Sat, 03 Oct 2009 20:36:00 +0000

Recently I didn’t post because I’ve got several training from company I work with. I have felt that I become busy man although I don’t. Still I want to continue express my electronic and programming experience in this blog. Still I’ll do research and simulate all I know.

Recently I have not updated my chess engine at all. It is still not finished yet. Still 0 %. But I will continue to do programming again. Then finally upload my first game.

Fun-digital.blogspot.com is not over.

Chess Engine for Chess Robot

noreply@blogger.com (Mas Tian) — Fri, 24 Jul 2009 19:41:00 +0000

At this moment I prepare for making chess robot which implement machine vision, robot arm, and chess engine. One of my parts is making chess engine. I can make the pc board myself. But still until now I haven’t finished chess engine. I have three task, they are pc board, chess engine, board recognition, and chess symbol recognition.

Back to chess engine, I make chess engine with C++. Based on C application on tree, I want to make it can analyze the best move based on n-steps prediction. I found that best moved is based on sum of score of every single move.

Chess engine I make is black or white. Extra point I make is easy to plug with another board that other people make. Chess board and chess engine I talk is not like in other web. I still beginner and some engine take years to beat its programmer. Hmmm.

In other to make great chess engine is mastering tree. I start learning tree 2 weeks ago even though I have ever made it some years ago. Then I realize the problem is not about tree but processing and memory. Controlling both of them is very difficult. My chess engine is about 0.5%.

So when will I finish my chess robot?

Mastering Visual C++ 6 in One Month through Planet Source Code and Ebooks

noreply@blogger.com (Mas Tian) — Sun, 28 Jun 2009 09:32:00 +0000

Mastering does not just know the basic but master every single thing that Visual C++ could. So I was looking for source code that can be downloaded for free. So I opened Planet Source Code.

I downloaded a lot source codes. Every code about chess and image and also visual c++ written were downloaded by me. But as guest I could download 5 only.

How do I download source code or anything from low security website? Then I used page FRAME so I can download them all. Hehehe. Thank you Planet Source Code.

Ebooks that I am using now are different from before. Here is the list
1> Programming Windows with MFC 2nd ed by Jeff Prosise
2> Developing Professional Applications in Windows 98 and NT Using MFC by Marshall Brain and Lance Lovette
3> MFC Black Book by Al Williams
4> Learn the MFC C++ Classes by Shirley Wodtke

Now I announce my self that I am now Intermediate Visual C++ Programmer although I haven’t finished my Chess Game Programming Project with Visual C++ 6. Ask to me if you have some question. I would likely to help anyone.

Visual C++ is very difficult

noreply@blogger.com (Mas Tian) — Fri, 26 Jun 2009 10:18:00 +0000

It’s very surprising that Visual C++ 6 is very difficult. My latest promoter said, “You better use Visual C++ 2005 or above than Visual C++ 6”.

My programming language background is C. I could handle TURBO C Compiler, Code Vision, Micro C, and CCS C Compiler. I used TURBO C at my first semester. Code Vision, Micro C, and CCS C are C Compiler for microcontroller.

Then I know my weakness. I weak at object oriented programming. I thought I can program “object oriented” Visual C++ 6 as easy as Visual Basic. Then I read these several ebooks that I downloaded from gigapedia and flazx even though they are not very useful.

1. mastering visual c++ 6
2. Fast Track Visual C++ 6 Programming
3. Visual C++ 6 The Complete Reference
4. SAMS Teach Yourself Visual C++ 6 in 21Days
5. Visual C++ 6 For Dummies

The last three ebooks are the best one for me because I am newbie, maybe. Thank you for all free ebooks. But are they really free or not?

Please suggest me the best Visual C++ 6 book!

Next Programming project

noreply@blogger.com (Mas Tian) — Fri, 26 Jun 2009 10:15:00 +0000

This is my second project that I post in this blog. This is not my own project. I just assist Mr. X to finish his bachelor thesis. Then the title is…. Still don’t know the title. Theme is hand machine, machine vision, and chess game engine.

I just do chess game engine. The engine I make is not engine made by me, but MIGOYA chess engine. Then several problems occur.

1. Mr. X is using Visual C++ 2008 for his final project but my computer couldn’t handle it. So I use

2. Visual C++ 6 even though I am newbie at Visual C++.
MIGOYA chess engine is build with Visual Basic.

Thanks for MIGOYA. I now can work to finish my task, Chess Game Engine.

Return

Finally again I’m post this blog, fun-digital.blogspot.com.

I’m currently fresh graduate of some university. Thank you for all of your support. Finally I finished my Sound Tracker Mobile Robot. Although I finished my thesis for three semesters, I certainty believe that my skill is useful for nowadays technology. However…

Now global crisis haunt me. People are fired especially from electronic company including Nokia, Sony, and so on. Can my skill be useful for nowadays technology?

I am currently job seeker. For the time being I spent my time with Programming DirectX, Learning Japanese, and Preparing TOEFL. Please support me! Then the extra point is I want to do posting at least every week.

Why DirectX, Japanese, and TOEFL?

NN Headache

noreply@blogger.com (Mas Tian) — Tue, 22 Apr 2008 20:29:00 +0000

My final project is about sound localization. For finishing my project at least I should know about Neural Network concept and its application.

Never knowing about neural network before make me regret. With my ordinary programming skill I can’t finish it. What is my problem?

I don’t have any problem and some other algorithm, but what make me regret in programming especially in digital electronic are:

1. I still can’t extract from math, such as differential, integral, and something like that. So when I have to program that contain integral, or even sometime double integral, I always give up. When I ask my lecturer assistants, they don’t answer about it. I don’t know about there are some major issues that they truly don’t understand about extracting from mathematic into program or they hide their knowledge from other.

2. Digital electronics are vary but when you use truly digital electronics, such us gate, multiplexer, decoder, and flip-flop, is not simple rather complicated. But thanks for development of computer, now we can use simple embedded microcontroller.

3. With microcontroller designing electronic system become easier, but not optimized. FPGA optimize programming better than MCU because it is truly digital-electronic.

So I decide to use microcontroller rather FPGA. I hope I will finish my electronic project soon So I can post my wonderful experience in this digital electronic programming blog.

Found Free Genetic Algorithm Ebook

noreply@blogger.com (Mas Tian) — Sun, 13 Apr 2008 19:33:00 +0000

Today is my glorious day. I found ebook for free. I think it is rare.

Then I check it in google blog. I found that this ebook is being promote by another ebook so I will not try to promote it.

The title is “A Field Guide to Genetic Programming”. “A field guide” is for newbie or for expert. I figure out Genetic Programming as how to make program and apply Genetic Algorithm in your field. Am I true?

Here the description:

Genetic programming (GP) is a systematic, domain-independent method for getting computers to solve problems automatically starting from a high-level statement of what needs to be done. Using ideas from natural evolution, GP starts from an ooze of random computer programs, and progressively refines them through processes of mutation and sexual recombination, until high-fitness solutions emerge. All this without the user having to know or specify the form or structure of solutions in advance. GP has generated a plethora of human-competitive results and applications, including novel scientific discoveries and patentable inventions.

So download it at http://www.lulu.com/content/2167025 for FREE. You can find FREE ebook at digital electronic programming blog.

Programming digital electronic blog is back

noreply@blogger.com (Mas Tian) — Tue, 25 Mar 2008 18:56:00 +0000

Fun-digital is back

Recently I have so many things that I have done through. I learnt a lot of things back there. Starting at op amp circuit, transistor circuit switching, speaker audio, microcontroller, DC motor, and in programming is artificial neural network. All of them are for my final project.

But Finishing my final project, design and implementation of mobile robot sound tracker, is still my top priority. This mobile robot implement microphones as sensor, you can call it microphones array. Then data that I received from microphone, I use microcontroller to specify the sound source direction.

To implement my digital electronic circuit knowledge, I tried to make switches from BJT transistor. My transistor switching is work now. Then I know how hard to make good switch. Why do I use transistor as switch? I’ll post this thing later.

Now I am still busy with amplifier circuit to interface with my digital electronic circuit through ADC (Analog Digital Conversion). I want to make it stable and precision. Follow me!

Is programming digital electronic fun?

Asking MicroController at Forum

noreply@blogger.com (Mas Tian) — Thu, 29 Nov 2007 21:06:00 +0000

Recently I looking forum that will help me through any obstacle. What I am facing now is FINAL PROJECT. Searching, Researching, Coding, Compiling, Testing, and Failing are my daily activity.

Now I am stuck because MicroController I use doesn't have a lot memory and more complex is my compiler doesn't support large code to compile cause DEMO LIMIT.

I hope This list of electronic forum will help me.

How to Fix and Repair ANY “Error Message” on Your Flash Disk

noreply@blogger.com (Mas Tian) — Sun, 04 Nov 2007 21:11:00 +0000

This is based on my experiences. Almost a month I scan, format, and wipe my flash disk. Finally conclusion appeared in my mind.

Please note, these technique work for me and maybe don’t work for you. If your Flash Disk is under warranty it is better to get new one before your try these techniques. Try to read your i/o flash disk with some utilities so you know it is not physically damaged. I use Ontrack Easy Recovery Professional which has Data Advisor diagnostic features because I think it work on flash disk too.

These Techniques are works for flash disk drive / pen drive.

Multi Volume Message.

-> Just format your removable disk. You will find some hidden file after that.

File Can Not be Deleted Message.

-> If this file is not contain or not virus, do scan disk. How do I find it is under virus or not? The answer is I don’t know it either. There are several trick to know it but I can’t write it know because the virus issues has been rapidly grown up.

No Disk Inserted Message.

-> Format it! If you can’t format it, it means you can’t fix your flash disk. Format it with FAT 32, not FAT 16 or you will be sorry. It is worked! If it is not, I cannot help you.

FlashDisk Full Message.

-> Format it with FAT 32, not FAT 16 or you will be sorry. Some time is working, some time is not depend on your flash disk condition.

Write Protected Error Message.

-> This message only can be repaired by destroyed data utility or wipe utility. This software work for deleted or formatted data to be destroyed and can’t be recovered. I used Ace Utilities that has 4 methods, Pseudorandom Data, US DoD 5220 22-M (8-306./E), DoD 5220 22-M (8-306./E,C and E), and Gutmann. After that you can check your flash drive with Format Recovery, not Delete Recovery, because they are different. I use Ontrack Easy Recovery Professional. . If it doesn’t work, format it first then wipe it.

-> If you cannot fix it, see the progress bar of wipe utillity. It is finish or not. If not you can not fix it with any utility. First try low level format first. I don't know what kind utility to work with but I think it will work.

-> This the last. Try copy large file into your flash disk. The bigger file better result. Then when after you copy it, "Write Protected Error Message" will appear. Don't worry! After this you will face Problem no.8 "My File is Empty but Used Space is Above xxMB".

I/O Device Error Message.

-> Same with previous error. This message only can be repaired by destroyed data utility or wipe utility. This software work for deleted or formatted data to be destroyed and can’t be recovered. I use Ace Utilities that has 4 wipe methods, Pseudorandom Data, US DoD 5220 22-M (8-306./E), DoD 5220 22-M (8-306./E,C and E), and Gutmann. After that you can check your flash drive with Format Recovery, not Delete Recovery, because they are different. I use Ontrack Easy Recovery Professional. If it doesn’t work, format it first then wipe it.

My Total Capacity is less than The Original Total Capacity.

-> I don’t know how to fix it because I never face it before. My analysis, same with Write Protected Error Message, is format it first then wipes it.

My File is Empty but Used Space is Above xxMB (xx is Number)

-> Symptom’s are almost same with Write Protected Error Message but it can not be fixed. I tried to use hdd regenerator that working on hard disk but no flash disk drive found. If you format it, Write Protected Error Message will appear. What should I do? Never mind. Just use your flash disk. If Write Protected Error Message appears, format it. Then Write Protected Error Message will appear after you copy some big files into it. Don’t worry. Click OK Button. You can still use your flash drive but you lose certain space.

---

I hope everyone is having fun if these methods don’t work. Otherwise YELL at me please...

Finally I fixed my flash disk

noreply@blogger.com (Mas Tian) — Thu, 27 Sep 2007 10:30:00 +0000

With happiness I am posting at this post. Continuing about yesterday post, today I finally realize I did. I fixed my flash disk. I spent a whole night, more than 7 hours to fix my flash disk. Than this morning after did several test to my flash disk, I know I fixed my flash disk.

I don’t give you a full report how to fix my flash disk yet. But I will post that report in the next post about “How to fix Your Flash Disk”. The reason is I want to give you special posting for all

My Flash Disk Damaged For Second Time a Row in One Night

noreply@blogger.com (Mas Tian) — Wed, 26 Sep 2007 05:28:00 +0000

A Good News Becomes Bad News. Yesterday I spent a whole day to figure out how to fix my flash disk. While I do that, I prepare to finish my final project. Although I tend to learn about my study, last night I actually fixed it. A good news become bad news when I found my self damaged again this morning. What?

My flash disk was damaged by unknown thing. In digital circuit a lot of thing could happen anytime anywhere. My prediction is my flash damaged because deleted corrupted file, bad sector, or flash disk circuit problem. How to prepare my flash disk? My flash disk problem is about the difference in initial capacity and actual capacity. Of course the actual capacity became smaller to the initial capacity. The actual capacity is 114 MB and the initial capacity is 4GB. What!!!

Yesterday I try to fix my flash disk. My motivation to fix my flash disk because I am currently Electronical Engineering and my speciality is Digital Electronic. I can’t tell you this product name because it be able to shame company reputation. I try to fix with two tools, recovery tools and optimizer utility tools. I can’t tell you the product name either. He..he..he..

While scanning, formatting, and wiping my damaged flash disk I read book about mathematical tool in C++ and Java. I can’t tell you the book title because I don’t remember the book title because my book in my home and I post at campus. I plug in my flash disk in my lab computer in my campus after that I realize that I can not copy to my flash disk again. Sigh..

Desperate College Student is Searching Guideline for His Final Project

noreply@blogger.com (Mas Tian) — Mon, 24 Sep 2007 10:52:00 +0000

Who is this desperate college student? Do you figure out who he/she is? He/ She must be same as me, as engineering college student.

I am doing final project now. I don’t know where place to start to. Looking around many forum over on the internet make me feel like crazy. This heavy pressure…

What should I do? My supervisor didn’t help me. Then day by day I didn’t do anything.

I think I can finish my project this semester but I can’t. This reality came beyond my imagination. I can’t concentrate about my project. What should I do?

My final project is “Design and Implementation of Mobile Robot Sound Tracker Based on Artificial Neural Network”. So what is the main principle of system? I found it. This system includes Mobile Robot, Digital Signal Processing, and Artificial Neural Network. After that search through internet and found few forums. I think I will… What should I post?

Here is the list of electronic forums:

http://findit-fixit.sensorsmag.com/

http://forum.allaboutcircuits.com/

http://www.audiotstation.com/forum/

http://forums.di.fm/

http://aimusic.com/forum/

http://artificialintelligence.the-aria.net/board/

http://justbasic.conforums.com/

I hope at this forum I would find the answer of my problem.

I am Searching Programming Digital Electronic Forums over the Internet

noreply@blogger.com (Mas Tian) — Fri, 21 Sep 2007 23:09:00 +0000

This is the first time I looking for Programming Digital Electronic Forums over the Internet. I search through Google Search Engine with keyword:

"Electronic Forum"

So I have list of few forum I trust one:

www.thescienceforum.com

www.sylvainmoreau.com/forumstudioelectronics/

www.ck-electronic.dk/forum/ frys.sthomas.net/forums/

forum.scienceprog.com/ matrixmultimedia.com/mmforums/

forums.di.fm

www.crazyengineers.com/forum/

forums.mcmb2b.com/

forums.spodesabode.com

Still I am not sure with above list because I do search because I need. I need forum where can I look for good resource for finishing my final project “Design and Implementation Mobile Robot Sound Tracker Based on Artificial Neural Network”.

So I am looking for Artificial Intelligent Forums, Digital Signal Processing Forums, and Microcontroller Forums. Please note because I still confuse to use Personal Computer (PC) or MicroController (MC).

Is My Proposal, that include Digital System and Programming, Accepted or NOT

noreply@blogger.com (Mas Tian) — Fri, 14 Sep 2007 08:40:00 +0000

Curently I am college student, and this semester is my time. I have to finish my final project on this semester because this is my 9th semester.

Time after time. More and more brainstorming. How to make good proposal? After several practice, finally I come with new idea.

Although my idea is not new idea, it’s okay. My idea is about “robot that can localize object through sound”. Then I picked several title from papers that available in internet. Finally my title is “Design and Implementation Mobile Robot Sound Tracker Based on Artificial Neural Network”.

Mobile robot based on artificial neural network or just neural network is not new. Moreover mobile robot that can localize sound through microphones is not new either because I have several paper including that title from early 1990’s.

My system is two audio sensor (microphones) and neural network. After audio sensors, I think it’s better if I digitalize the signal first. Then I can measure the difference of level and time with Interaural Level Difference (ILD) and Interaural Time Difference (ITD). My system can count where the audio source location through that differences. I think it is good.

So I am waiting my proposal accepted then.

What Should I Post in This Blog

noreply@blogger.com (Mas Tian) — Wed, 05 Sep 2007 09:05:00 +0000

What should I post in this blog? In these past few days I can’t figure out what post.

I do a lot of researches in past few days. A lot of thing happened at that time. While research, I collect and write a lot. But it is still not enough quality content to post.

Tough because of this blog title is “Fun Digital Blog - Digital Electronic and Programming is So Much Fun”. I think I pick the most difficult content. But I doesn’t feel sorry because I like this topic, Fun Digital Blog.

Although digital electronic is fun, I need more time and more effort to write frequently relevance and quality content.

My Motivation At This Digital Age

noreply@blogger.com (Mas Tian) — Tue, 28 Aug 2007 22:07:00 +0000

In this post ......

Becoming the most well known electronic engineer is my dream. My life fulfill with dream and hope.

Dreaming and hope is my power to empower my motivation because motivation is the key of success.

I saw my video collection of robot experiment. I saw the great thing. I want to make robot, my own design robot complete with analog and digital system inside. Most of my video collection is robot from Japan so I want to live there in order to fulfill my destiny.

Almost facing final project make me feel little bit nervous all the time. What title should I take? I think I will make robot in my final project with Artificial Intelligence (AI) inside.

Little Explanation About Program, Algorithm, and Any Stuff Alike

noreply@blogger.com (Mas Tian) — Tue, 28 Aug 2007 21:52:00 +0000

I met about programming and other stuff at the first semester.

What is program? We can meet any little thing about program in computer operations. Program is a detailed sequence of instructions representing an algorithm (the necessary steps in solving a problem) that can be implemented by a computer. Focusing in electronic engineering, we can program some Integrated Circuit (IC), Micro Controller (MC) and Programmable Logic Device (PLD) in instance.

Writing your own program isn't hard. If you've always been curious about any computer programming but were intimidated by the hard-to-read books, less-than-useful software, or hard-to-understand explanations from any experts, then you should follow the following little tips.

Relax. So grab some snack foods, a comfortable seat, and get ready to program any computer and make it finally to what you want it to do.

Try. So try any program that written in any book you have or over internet you find.

Human Interact with Machine and Getting Love Each Other

noreply@blogger.com (Mas Tian) — Tue, 28 Aug 2007 21:21:00 +0000

What a strange statement.

Human interact with machine is our daily live. When focus on digital era that interaction becomes primary. People use telephone, telecommunication service, to speak with other.
That telecommunication service may use some complex digital thing.

Human interact with human by speaking and hearing. Human interact with machine by speaking and hearing become complex, because machine has limit of capable to. In digital machine only know about any simple tasks. Involving communication through vision, sound, touch, and smell is become demanding.

People want to order machine to turn on AC (Air Conditioner) by voice. Autonomous machine have to complete series of tasks. People want to discover unknown places or dangerous places by sound, vision, touch, and smell.

How machine interact with human through vision, sound, touch, and smell? Machine sees through camera. Machine hears through microphone. What about touch and smell? It’s all about sensor. Sensor is a device that samples a phenomenon, and delivers a proportionate current or voltage in terms of which the intensity of the phenomenon can be measured, or with which control action can be initiated. I’ll post more about sensor later.

The important is machine have to translate any information from camera to see or from microphone to hear. Of course the translation has to be in digital information, true or false statement.

Human make the translator. Human make any decision how and what for machine work. Human make the algorithm. Human make program that control stuff. Every thing is made by human at least for the first time. If you see program that write its own program, it is impossible.
Human and machine getting love each other. That is nowadays because human interact with machine is not should but have to. After human have to interact with machine, that thing becomes habit. Moreover some people are getting addicted to use machine. That machine include machine that based on digital system.

...
Becoming addicted is the factor. I think...

Digital and Communication System

noreply@blogger.com (Mas Tian) — Tue, 28 Aug 2007 21:17:00 +0000

Some long and long posting...

I post today at digital age where communication is the most important aspect in the whole world.

Digital and communication are both identical. I think ….because communication system nowadays based on digital system. For example internet and SMS (Short Message Service). Moreover digital is based on communication system because digital is the way to interact not only between human and machine but also between machine and machine.

Definition of machine is human made thing which is made for some reason. Hmm..
While posting I imagine if robot era will come. I imagine when robot can interact with other robot or human. Of course robot is able to learn and make its own decision. Maybe cyborg is also present. Cyborg is robot that human alike form.

Back to present…

Communication between machine and machine is use binary 1 or 0, true or false statement. But only 1 and 0 only make very simple communication. What? I mean very simple tense, one tense, only yes or no, true or false. In example, I have secret or I don’t have secret. Same subject, predicate, and object. The difference is positive or negative statement.

In more complex communication machine more decision, more subject, more predicate, more object are made. More subject!! More subjects mean more machine as subject isn’t it? I think it’s strange at the first time. It doesn’t matter anymore nowadays. What an explanation!! Still don’t have any example. I still can’t tell more.

Machines are interacting with machine language. Machine language is not only Yes or No statement but also complex algorithm that not only making some decision but also learning Online or Offline. I talk about learning so it means Artificial Intelligent (AI).

Machine has it own intelligent! Is it true? That intelligent only describe in machine language. We should learn some machine language to be able to understand this stuff.
My next posting is interaction between human and machine.

This is My First Post Baby.

noreply@blogger.com (Mas Tian) — Tue, 28 Aug 2007 21:05:00 +0000

This is my first post baby. Still have no experience about blog cause me write this stuff for an hour. What should I post in this blog make me feels at terrible disaster. Brainstorming, more and more brainstorming.

I face computer with headache in my head. What should I write about? My blog name is fun-digital.blogspot.com, but what should about digital. My eyes become red because I keep staring in front of my monitor.

Then I hear my mp3 collection. I figure out what should I post in the next post. I thing brainstorming is important. But I think my mp3 collection is the most important. I feel like dying at the ocean of music.

I wrote this post at 1 am then finish at 1:53 am. My post time is difference with my write time because I wrote my post on my Personal Computer (PC) that is not connected with internet.
