Building Robots with Java Embedded

Join us for the new training on building robots with Java Embedded. This training is free and will be live on hangout or YouTube, Tuesday April 15 at 10:00am Singapore time; 7:30am India Mumbai; 11:00am Tokyo Japan; 2:00am UTC. Globalcode founder and embedded expert Vinicius Senger will focus on homemade robots and the Lego Mindstorms robots.

This training offers a chance to direct questions to top experts and get you started with your own project.  Once you have your own project ready, submit a video and the code by May 30 for a chance to win a trip to JavaOne 2014.

More resources and the support forum are available online. Learn about the Challenge rules.

Hacking with Raspberry Pi and Java

Two new videos about Raspberry Pi GPIO with Java are now available. This hands-on training  is part of the IoT Developer Challenge and will help you to create a winning project to submit. This is a great opportunity to win a trip to JavaOne 2014! Submissions are accepted until May 30, 2014

In the first video, you will learn about the Raspberry Pi set up and the installation of Java SE Embedded and JavaFX. In the second video below, expert Vinicius Senger explains the Raspberry Pi GPIO and protocols as well as how to use the Pi4J project, a set of libraries enabling the access of the Raspberry Pi with Java. Vinicius also gives several demonstrations using a camera, LED lights, buttons and a relay board to connect to appliances. You can download the code of his demonstrations, including Pi4J Helloworld, PiPicture, Twitter4Pi and Lcdl2C

Compete in the IoT Developer Challenge!


Show the world your embedded Java + Internet of Things (IoT) application for a chance to win a trip to JavaOne 2014! 12 winners will receive a trip to JavaOne 2014, the #1 place to meet world-renowned Java experts. In addition, six students will receive laptops and certification vouchers. Team up and submit the video and code of your project  by May 30, 2014.

Don't know how to start? We are providing eight free online training sessions in March and April. They will introduce you to embedded Java Embedded, IoT, Raspberry Pi and more. Everyone who registers gets a chance to win a Raspberry Pi starter kit.  

Need just a little bit of help? We will provide experts along the way -- regular "office hours." Ask questions on the Challenge forums and check the online resources. There may be some source code and solutions you can use for your project.  

At previous developer challenges, we've had developers:

  • Connect a doorbell to a camera, taking a picture and sending it to a cell phone when someone rings the doorbell.
  • Help blind people figure out which recycling container to use ("put it in the blue can" doesn't help!)
  •  Control a toy monster truck from a phone (Monster Truck As A Service!) 
  •  Connect a heart monitor to Google glass so your doctor or trainer can see your heart rate.

This short video shows them in action: 

Entries will be judged based on their implementation, innovation and usefulness:

  • Quality: a well-implemented project that uses Oracle Java Embedded with computer boards, devices or IoT Technologies
  • Innovation: a new and innovative way of using Java Embedded.
  • Usefulness: a project that meets a business need.

Internet of Things (IoT) Hackathon in Brazil

SouJava is running a Raspberry Pi and Java hackathon at Campus Party, the week-long technology gathering of geeks, developers, gamers, scientists, and students in Brazil. Sponsored by Oracle Technology Network, the hackathon is designed for enthusiasts who want to create IoT projects with Raspberry Pi and Java. The objectives are for attendees to learn, practice, and innovative while creating an IoT project

Java evangelist Angela Caicedo opened the hackathon with an overview of IoT and Java development. Over two days, participants will build teams, brainstorm, attend training, get a kit from the organizers and hack on their own project. Onsite experts will be available to help participants. They are veteran Java developers of web, enterprise and embedded development. Among them are GlobalCode founder Vinicius Senger, senior developer Rubens Saraiva, SouJava leader Bruno Souza, Java Champion Yara Senger, product manager Bruno Borges and senior mobile developer Ricardo Ogliari

Internet of Things Interview

Java Evangelist Jim Weaver, Senior Engineer Gerrit Grunwald and Community Manager Yolande Poirier discussed the Internet of Things(IoT), Java Embedded, and the new IoT community page on Java.net. The page gathers blogs, resources and many sample applications from Java developers who create embedded applications with Java. "If we prepare developers correctly to be able to program those devices and put structures in place that monitor and control those devices, then we can have a very productive world of development: one that is powered by Java, that has the underline security and needed APIs, and that leverages Java developer expertise" Jim explained. 

"I use one Raspberry Pi with Open Dophin and many sensors to synchronize data instead of multiple Raspberry Pi's" explained Gerrit Grunwald. "Over the last 10 years, the server side was prepared very well and now it is time for the embedded side to catch up and combine everything in one big Java world" he added

Devoxx HackFest In-Action Attracts Developers

by guest blogger Geert Bevin, Senior Developer, ZeroTurnaround. Geert Bevin presented the Leap Motion at IoT Hack Fest

The Raspberry PI and Leap Motion hands-on labs at Devoxx 2013 started with a packed room, we even had to fetch additional chairs for people standing in the back. Vinicius and Yara senger explained their super useful embedded devices panel where many sensors and boards can be accessed through easy REST URLs.



After my quick overview of the Leap Motion controller, the attendees could experiment with all available devices and get acquainted with it before starting a hack. Surprisingly though, only a couple of developers were interested to stick around for the real hack-fest that lasted the rest of the day.

 We set up everything upstairs in the Devoxx open-space and started hacking with the brave few that showed up. As the day advanced though, more and more people came by and were impressed to see the work in progress. On Tuesday evening all the tables were packed with hackers testing and building cool stuff. Ten of them were able to finish their project and some even presented it on video for the Oracle Technology Network YouTube channel.


I had a great time and it's wonderful to see how easily accessible physical embedded devices speak to the imagination of so many developers. 

Here's my hack that lets you control a strip of multi-colored lights that are connected to Arduino over a Raspberry Pi and are remotely controlled with the Leap Motion controller over the network.
