"We are always creating new IoT applications and encouraging others to improve them. Lhings is the networking tool that let us make it very easy. This time we wanted to make something we use in our everyday lives which is traditionally non-technical, as is a table, to be connected to the Internet and then provide new services that could be useful in some applications" explains José Pereda, who is part of the Lhings team. Based in Spain, the team won aJavaOne trip during IoT Developer Challenge.
"We wanted to show that IoT is useful in real scenarios and it's accessible to anyone. Likewise, we would like to encourage developers to reproduce and improve it!" further explains José. You will get a chance to meet them at JavaOne.
José is also presenting four talks at JavaOne
- JavaFX 3D: Advanced Application Development
- How to Build the Game 2048 with JavaFX and Java 8: Lessons Learned
- Debugging and Profiling Robots with James Gosling
- Create the Game 2048 with Java 8 and JavaFX

This is your last chance to win a JavaOne trip. Submit a project video and code for the IoT Developer Challenge by this Friday, May 30. 12 JavaOne trips will be awarded to 3 professional teams and one student team. Members of two student teams will win laptops and certification training vouchers.
Ask your last minute questions on the coaching form or the Challenge forum. They will be answered promptly. Your project video should explain how your project works. Any common video format such as mp4, avi, mov is fine.
Your project must use Java Embedded - whether it is Java SE Embedded or ME Embedded - with the hardware of your choice, including any devices, boards and IoT technology. The project will be judged based on the project implementation, innovation and business usefulness. More details on the IoT Developer Challenge website
Just for fun! Here is a video of Vinicius Senger giving a tour of his home lab, and showing his boards and gadgets.

"The Gemalto concept board has 2G and 3G support, so you can send text messages, place a call, write Java Midlets and Arduino shields support" explains Vinicius Senger.
In this video, he presents step-by-step tutorials on how to configure the Gemalto boards and to create a project controlling LED lights. You can download this project as well as the fan caller demo here. Visit the IoT Developer Challenge website for more training videos. Once you have a working project, submit a video and the code of your project for a chance to win a JavaOne trip!
In the video below, Vinicius explains how to create a fan caller

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.
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.

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

"The Leap Motion controller is a tiny device that measures the position of your hands in 3D space and it gives you a bunch of information so you can do things with that data." explained ZeroTurnaround Senior Engineer Geert Bevin. He created an application that allows users to make music with their hands; another that maps a series of gestures for keyboard and mouse commands for games. He showcased how to use it to control a computer and a game.

The robot is connected to touch and color sensors, has a gyroscope to orient and prevent it from falling, 2 motors for the wheels and another for arms, and an infrared sensor for the remote control.

Geert Bevin created an application controlling multi-colored led strip with hand gestures. The Leap Motion controller detects hand position in 3D-space and sends the X/Y/Z data straight to the led strip to control the intensity of the red/green/blue lights. The led strip was connected to a Raspberry PI with an Arduino bridge and could be piloted through REST calls running on an embedded Java server. In this video, Geert explains the project.
