My professor was visiting me to review my master thesis. My software at IMTEK open house. IMTEK Clean Room Smartbracket data acquisition electronic device. Cekli PhotoLab, photo editor software that I have developed under sourceforge project. Yohanes Wahyu Nurcahyo: Yohanes Wahyu Nurcahyo
Welcome to my personal website that I maintain by myself. I share the information about my previous and current projects, my ordinary life and some of my knowledge that maybe useful for you. I would like to share my knowledge about computer in common and programming in C++. Please do not hesitate to contact me for futher information.

NeuroProbes (European Project)

The proposed NeuroProbes project aims to design and build multi-electrode arrays and to integrate electrical recording, drug dispensing, and biochemical analysis, while maintaining compatibility with techniques such as fMRI. It also proposes to innovate by providing integrated telemetry. In this project, I work with IMTEK team.

Smart Bracket using Stress Sensor Chip

In this recent time, there are many people that wish to have nice teeth, white and in correct formation. But some people have teeth that are not in proper position. Therefore, they use bracket or dental brace that can be attached by a dentist. This is not an easy task for the dentist to attach the bracket to the teeth. This difficulty of attachment process results high percentage failure of the bracket attachment that can break some teeth.

GUI for Four-Degree of Freedom Solid State MEMS Joystick

IMTEK researcher team has developed a joystick based on single chip stress sensor. In this project, I am the one and only programmer for Graphical User Interface for data acquisition and hardware controller. I developed also the LabView driver for this chip. Using this driver, the joystick calibration process can be perfomed automatically without to much supervised by human and much faster. I have developed both software using Visual C++.

Strain Measurements Using Optical Interference Techniques

In this master thesis, the strain of plasma-enhanced chemical vapor deposition (PECVD) silicon nitride (SiNx) microtensile specimens has been evaluated using two dimensional gratings. Physical vapor deposition (PVD) of 20 nm thick gold as two dimensional gratings with period vary from 4 µm to 18 µm were deposited on the top surface of mechanical structures and silicon nitride specimens. Both lateral and axial strains of four silicon nitride specimens can be measured by examining the laser interference pattern of the gratings.

Cekli PhotoLab

Cekli PhotoLab is my project under sourceforge.net framework. It is an image processing software written with C++ using wxWidgets library. Based on wxWidgets allows compiling Cekli PhotoLab under several platforms like Linux, MacOS, Windows, Windows XP, PDA and more. I maintain the project by myself from the C++ code, documentation and the website for publication.

VDE - Verband der Elektrotechnik Elektronik Informationstechnik e.V.

Since Februar 2008, I am a member of VDE. I interest to this organization because this organization provides information, excursion tour to many companies and possibilities to contact with professional. As a member I have followed VDE activities, especially with VDE Süd Baden. I have came to CeBIT, a big electronic exhibition in Hannover, Germany. We went from Freiburg to Hannover via several cities to pick up other VDE member.

Forum - Content Management System (CMS)

The Content Management System in the form of Forum is a software for a website with purposing to manage the discussion between users. The website can have many topic for the forum with one main topic for each website. The example for the topics are hobby, technology, computer and more. Each user can send his/her question/answer/news to the website and the other user can reply or gives other opinion.

Content Management System (CMS)

From now on, it is not efficient anymore to write the html code for each page of our website. Beside html can only be used as static website, the further development is also very difficult. Therefore we have to use an already done software for the website.

Developing the Powerful Website

I have developing several websites, some of them are aimed to get the financial benefit. This article is explained the website development based on my experience. Developing a website for now on is very easy due to many web application and resources available. But developing a website that provides many benefits is very difficult and not many people can do that. We could see that there are many dotcom companies were failed to success. In this article I will explain about how to make a website that provides benefits for both users and website provider.

My New Personal Website was Online

Finally, I have finished my new personal website based on Drupal. Even though this website look simple and clean, but the installation of this website was not that simple. I need several weeks only for Drupal modules installation because each module has different installation method. I use Drupal because it is very simple to use and very powerfull. I have everything that I need to developed this website.
