This project attempts to create an obstruction avoiding robot which can automatically sense the presence of an obstruction in its path and avoid them. It intelligently detects barrier present in its path through the ultrasonic sensors, with the help of the internal code from the Arduino UNO, decisions are made to avoid the barriers. This has been achieved by using an ultrasonic sensor and the development board Arduino UNO. The ultrasonic sensor is mounted on a servo motor at the front of the vehicle for a wider field of view. The ultrasonic sensor acquires data which is processed by the Arduino which then decides the direction of travel for the robot. The robot requires low voltage and minimal maintenance for continued operation. Arduino being an open-source software has gained popularity for the creation of basic prototypes due to its relative simplicity in both design and coding. It also boasts of a large online community of learners and engineers.

Fourier ptychographic microscopy (FPM) is a computational microscopy technique that enables large field of view and high-resolution microscopic imaging of biological samples. However, the FPM does not yet have an adequately capable open-source software. In order to fill this gap we are presenting novel, simple, universal, semi-automatic and highly intuitive graphical user interface (GUI) open-source application called the FPM app enabling wide-scale robust FPM reconstruction. Apart from implementing the FPM in accessible GUI app, we also made several improvements in the FPM image reconstruction process itself, making the FPM more automatic, noise-robust and faster.

The Face

The threaded online, also known as “forum,” collaboration method is widely used by open source software projects. As open source and Crowdsourcing [3] design approaches gain attention, there is a need to explore whether the threaded online method would compete with the more traditional method, face to face, in mechanical engineering design in terms of productivity. Our experiment shows that with a suitably sized challenge, the threaded online method does generate about equal productivity as the face-to-face method. However, the participation rates are lower in the threaded online method and the participants’ satisfaction with the experience was also less. This suggests that additional communication mechanisms are needed to facilitate the threaded online method, and management mechanisms should be imposed. We also identified two phenomena that warrant further investigation. The first is what we call “inertia loafing.” Enthusiasm among online community members is fragile. A small drop in satisfaction level can cause many to become unwilling to participate. The second is that an online community tends to have two kinds of members: “players” who are responsible for most content creation; and “cheer leaders” who provide feedback or provide an assisting function.

Open source software (OSS) has achieved great success and exerted significant impact on the software industry. OSS development takes online community as its organizational form, and developers voluntarily work for the project. In the project execution process, control aligns individual behaviors toward the organizational goals via the Internet and becomes critical to the success of OSS projects. This paper investigates the control modes in OSS project communities, and their effects on project performance. Based on a web survey and archival data from OSS projects, it is revealed that three types of control modes, that is, outcome, clanship, and self-control, are effective in an OSS project community. The study contributes to a better understanding of OSS project organizations and processes, and provides advice for OSS development.

By examining “who connects with whom” in an online community using social network analysis, this study tests the social drivers that shape the collaboration dynamics among a group of participants from SourceForge, the largest open source community on the Web. The formation of the online social network was explored by testing two distinct network attachment logics: strategic selection and homophily. Both logics received some support. Taken together, the results are suggestive of a “performance-based clustering” phenomenon within the OSS online community in which most collaborations involve accomplished developers, and novice developers tend to partner with less accomplished and less experienced peers.

Development Movement

This article introduces a new form of collaborative web-based editing which has become increasingly popular in recent years. It involves web users as reporters and co-producers for specialist news sites by allowing them to submit their own news reports and pointers to relevant articles elsewhere on the web, and sometimes even hands over editorial control to the online community altogether. Websites of this type move on from traditional journalistic gatekeeping approaches, where editors publish only what they regard as ‘fit to print’, to what is here termed gatewatching, where almost all incoming material is publicised, but with varying degrees of emphasis. Gatewatching sites frequently become major repositories of specialist information, turning into resource centre sites for their interest community, and are particularly common on the fringes of the open source software development movement. Some of these sites can be seen to directly apply open source ideals (direct involvement of the community, open access to all aspects of the development process) to the reporting of news, in effect making news itself an open source.

Kendali perangkat elektronika secara jarak jauh pada umumnya menggunakan remote infra merah ataupun menggunakan kendali sms gateway. Permasalahan terjadi Jika menggunakan Ired Pada saat pengiriman data,  maka antara infra merah sebagai transmiter dan receiver  harus berhadapan satu sama lain tanpa ada penghalang. Hal ini dapat menyulitkan dalam proses pengendalian perangkat elektronika secara jarak jauh. Sedangkan bila menggunakan sms gateway maka dibutuhkan pulsa “sms” untuk komunikasi data, sehingga pengendalian tidak effisien dan tidak praktis. Penelitian ini Bertujuan sebagai alternatif lain dalam pengendalian perangkat elektronika secara nirkabel yang ekonomis dan praktis. Board mikrokontroller yang digunakan pada penelitian ini bersifat open-source yaitu menggunakan board arduino uno. Untuk pembuatan aplikasi Android AndroBlue pada smartphone, dengan memanfaatkan pemrograman berbasis online dari ai2.appinventor.mit.edu.Cara penggunaan alat ini adalah dengan mengaktifkan Bluetooth pada Smartphone Android dan memberikan daya pada prototipe kendali perangkat elektronika, kemudian dilakukan pairing antara bluetooth pada smartphone dengan bluetooth yang ada pada prototipe kendali. Setelah terhubung, maka perangkat elektronika tersebut dapat dikendalikan dengan menggunakan aplikasi AndroBlue yang sudah terinstall pada smartphone. Dari hasil pengujian terhadap kendali perangkat elektronika secara jarak jauh dapat diketahui dari 10 kali uji coba dengan perbedaan jarak yang sudah ditentukan, tingkat keberhasilan  mencapai 80 %.
