Build a KittyCam using a Raspberry Pi and Node.js
During the summer, Tomomi Imura built a Node.js app which captured images from the Raspberry Pi camera module and used animal facial recognition to store them based on whether or not her pet cat was detected. The Pi uses a…
Lizard selfies with a Raspberry Pi
Roberto Marquez has set-up a Raspberry Pi to take pictures of his lizard. The Pi listens for a GPIO pin to change state, triggered by a capacitive touch sensor. All his Java code is available on GitHub. You can see a…
LEDs that move and mirror your hand movements with a Leap Motion and a Raspberry Pi
Over at PubNub, they’ve been using Java to do some great things. This time, they’re using it to interact with a Leap Motion. Movements in the user’s hands are replicated with servos. Attached to the servos are some 8×8 LED…
Run Java EE apps on the Raspberry Pi with Payara Micro
Payara Micro is a fantastic little Java server that requires no installation to get it running. All you need is Java installed on your Pi (which is default on Raspbian) and a simple command and you’re up and running. It’s…
Java, sensors and the I2C bus on the Raspberry Pi
Jose Cruz has continued his series on using sensors on a Raspberry Pi with Java. (You can see part 1 here) This time he tackles initialising the I2C bus on the Pi and then using Java to read sensor data…
Touchscreen JavaFX 8 on Raspberry Pi
Pance Cavkovski has written a nice tutorial on programming a touchscreen interface, using the PiTFT screen, using JavaFX 8. His project involves an NFC plug-in board which scans your access card and then prompts you to enter a code, thus…
Create an Internet of Things device using Java on the Raspberry Pi
Jose Cruz from Oracle has written a wiring and programming tutorial to read a flame sensor, movement sensor (PIR) and an ultrasonic distance sensor using Java ME 8. Read the tutorial here.
Remotely deploy projects to the Raspberry Pi using NetBeans IDE
Richard Bound has written a nice little tutorial on using a desktop computer running the NetBeans IDE to remotely deploy an application to the Raspberry Pi. Read it here.
45 Raspberry Pi cluster mines Java code
Lee Martie and his team took 45 Raspberry Pis and clustered them together. They mine Java code repositories on GitHub and provide an interface to search the code online. You can use the searching tool here.
