The Badge Magic Android app lets you control LED name badges using a Bluetooth connection. The app provides options to portray names and cliparts. For the data transfer from the smartphone to the LED badge it uses Bluetooth. An upcoming feature is the conversion of images to cliparts that can be shown on the badge.

Badge Magic

Badge Magic iOS

The development on the Badge Magic iOS app is starting. Our goal is to match the functionalities and features of the Android app. We want to control LED name badges using a Bluetooth Low Energy connection and to be able to transfer text and clipart from the iOS app to the badge magic device. Additionally user should be able to draw cliparts or convert their images to cliparts that can be shown on the device.


Neurolab Hardware

We are developing an open hardware platform for neuro-devices that can do measurements of brain waves or provide brain data to control other devices or play games. The neurolab hardware can be be plugged into a computer or smartphone. We are focusing on creating a device that collects as much data as possible through the forehead. The device could also be used for medical purposes or for meditation.


Neurolab Android

The Neurolab Android app enables users to use an open hardware neuro-device with a smartphone and do measurements of brain waves or play games controlled by the activity of their brains. Feedback channels to develop the app further can be visual or through sound.

Frequently Asked Questions

Who can participate

We are looking for great coders no matter the status, age, gender or background. However, in order to be one of the grand prize winners you need to be able to travel to the FOSSASIA OpenTechSummit to Singapore from March 19-22, 2020.

What are the prizes?

Everyone who gets five pull requests merged during the contest period will receive a digital certificate of participation from the FOSSASIA organization. Developers with 10 merged PRs or more will receive a Tshirt or other cool items from FOSSASIA (if postal distribution is feasible).
Out of the top ten contributors in the contest three grand prize winners will be chosen by the jury. The grand prize winners will receive 600 SGD in travel support (please provide blog post and receipt, reimbursement at the event) and a free speaker's ticket to the FOSSASIA Summit in Singapore from March 19-22. Plus, they will have the chance to present their work at the event. Other finalists will receive a 100 SGD travel voucher for a conference of their choice (please provide blog post) and a free ticket for the FOSSASIA summit, if they can attend.

How are the Winners chosen?

When deciding on the Winners, the jury will review the work of the 10 developers with the highest number of contributions gained during the contest. Apart from the code commits we expect two blog posts, community outreach, a screencast and other contributions.
Basically we are looking for good developers who are team players. That is why the sheer number of tasks is not the only main criteria for choosing the grand prize winners. Same as in GSoC we are looking for quality work. In the end from the 10 highest scoring developers, the jury will name 3 finalists as grand prize winners that will receive the travel stipend to attend the FOSSASIA OpenTechSummit. Because some tasks are more challenging than others just by the nature of the type of task (for example, heavy coding versus solving a text typo bug), it is entirely possible that someone who completed 15 issues could be chosen as a Grand Prize Winner over someone who completed 35 issues, if they are both among the top 10 contributors, they are eligible to be among the Winners.

How to contribute code in the contest?

* At first developers sign up on a Google form here to participate.
* Then FOSSASIA admins will add them to the FOSSASIA Code Heat team on GitHub within a week (usually earlier).
* Each developer then searches for issues that interests him/her and claims ownership of a particular issue. The developer works on the issue and if there are questions asks on the chat channel of the project. The main channel for decision making is however always the GitHub issue itself.
* Once finished, the developers make a pull request from his/her own forked repository to the development branch of the project and submit their work for review.
* Pull requests need to pass Travis builds, code CI tests and ensure migrations work.
* Mentors and core-developers from the organization evaluate the work submitted. If the work is accepted, the developer earns 1 point for each accepted pull request and 1 point if they close an issue. So you could earn two points if you close an issue with a pull requests. [Please Note: Sometimes developers try to “beat the system” by submitting lots of small improvements as pull requests. Please consider that the jury is mainly interested in the substantiality and quality of code contributions and the sheer number is not the main criteria.]
* After the pull request has been merged developers can claim another issue to work on if they wish.
* If the work needs polishing, the task remains open and the core-developer may give the submitter additional time and guidance on improving their work.
* If the work does not meet expectations, the task can be reopened for another developer contestant to claim and work on.
Please follow FOSSASIA Best Practices to achieve the desired outcome.

What other contributions are part of the contest?

Other contributions in the contest are blog posts, weekly scrum updates to the project mailing list, a screencast and organizing meetups using the eventyay platform . We would like to see the following contributions from participants in the contest:
* A weekly (or daily) scrum to the mailing list by Sunday 10AM your local time using the scrum helper

When does the contest begin? Can I join the contest at any time?

The contest begins at 9:00 AM (SGT/GMT+8) on September 15, 2019 and runs until 11:00 PM (SGT/GMT+8) on February 2, 2020. Participants should take the time to read through the contest website and familiarize themselves with the introductory information and Readme.md of the project before starting to work on an issue. Interested developers can join the contest at any time during the program.

How do developers register for the contest?

1. Developers should join the community and sign up for the following channels
* Signup for the FOSSASIA Newsletter
* Star and fork repositories you are interested in on GitHub
* Join the FOSSASIA Chat on Gitter
* Follow FOSSASIA on Twitter and the Codeheat Twitter account
* Like FOSSASIA on Facebook
* Join the FOSSASIA Group on Linkedin
* Follow the FOSSASIA Linkedin Page
* Subscribe to the FOSSASIA YouTube Channel
2. Once the contest is open developers will be able to sign up on a Google form here.
3. Developers will receive an invite to the FOSSASIA GitHub within a week (usually earlier). All developers should then make their participation public by showing their membership as “public” in their GitHub profile.

Why should developers participate in the contest? 

The idea of the contest is to introduce developers to the FOSSASIA projects and to provide an opportunity to build up their development profile, learn how to work according to Best Development Practices and ultimately become part of the development team. The contest also provides an entry point and preparation for future coding programs like the FOSSASIA Google Summer of Code.
Many young developers are not yet deeply familiar with Open Source and the contest is an easy way to get involved in this international community of developers, who want to help you learn and succeed. The contest is a gateway to learning new skills as well as learning to work in a collaborative software development team. At the end of the contest, developers can show their friends, teachers, co-developers and family members the work they did on public repositories and the project applications itself - used by people around the world.

What programming languages do participants need to know?

There are various programming languages used in FOSSASIA projects ranging from web front-end to back-end technologies and Linux technologies. You could even code on hardware firmwares and design hardware as a project. Here are a few languages that are popular: Java, Kotlin, Javascript, HTML, Python, C++, Shell Scripts.

What do I need to do to be among the winners?

For us everyone is a winner, who contributes in whatever way in the community. However in contest setting there are some points you should fulfil to increase your chances to be a finalist. To be among them it is important to work according to the FOSSASIA Best Practices and to provide the following:
* Continuous substantial contributions, pull requests, and code reviews
* Participate in chats on the project channels
* Provide continuous updates in weekly scrums, monthly blog posts
* Create one screencast and a presentation
* Provide a Gist with a list of the work outcome of your work by January 28, 2020

What is a scrum and where should I submit it?

A scrum is a simple update (also called standup) to inform others about what a developer is working on and if there are any impediments a developer encounters. In many company software projects developers provide a daily scrum in a live standup face to face. As Codeheat is not a full-time program and happening online, weekly scrum updates on the mailing list are a good start. If you are able to send out more scrums during the week that is definitely a bonus. Please use the FOSSASIA scrum helper to create your scrum report.
There are three questions that should be answered in a daily scrum mail:
1. What have you worked on last week/yesterday?
2. What are you planning to work on this week/today?
3. Are there any impediments that prevent you from achieving your goal?
Each answer should include a short sum up of the item and a link to the respective issue/pull request. Each pull request should have an issue that it is related to. Weekly scrum mails should be send out every Sunday morning before 10AM local time.

Which projects can I work on? Can I also contribute to other FOSSASIA projects as part of the contest?

You can always work on any project in the FOSSASIA GitHub org, but in the contest we count the contributions made in the projects listed on the Codeheat website.

How is the travel funding paid out and what happens if a grand prize winner is not able to get a visa? 

The travel funding is provided in cash at the FOSSASIA Summit itself. In the event a Grand Prize Winner is not able to join the FOSSASIA Summit because he/she cannot obtain a visa or for any other reason, the runner up selected by the jury will be chosen as the Grand Prize Winner and the original Grand Prize winner will receive the 100 SGD travel funding to attend a local event in his/her area (the original Grand Prize winner will retain the title as a winner).
