The Grand Finale In a previous post on Building a Raspberry Pi Cluster, I wrote about how we built a cluster using several Raspberry Pis. This cluster was used for hosting the WSO2Con App. In this post we will take a look at the finishing touches & some interesting information from WSO2Con 2013. The project was […]

“Hello World!” – This is likely the output of the first program you ever wrote when learning how to code. Setting up a device to stream temperature data is quickly becoming the de facto Internet of Things (IoT) “Hello World!” project. If printing “Hello World!” the first time was a long, frustrating task, you might

Raspberry Pi is quite suitable for robot creation. Its GPIO pins could be used to control the motors and sensors, and itself could work as a server, and get controlled via Internet. The Plan I am going to create a robot chassis, which could automatically avoid obstacle on the ground. Here is my plan: Hardware

Raspberry Pi is a sort of jack of all trades when it comes to being a single board computer based on the Arm processor. It can be a desktop, media player/streamer, web server, forensics machine, and do most of what all linux based machines can do. Pictured is the Raspberry Pi with some of it’s

Note: I only write about what I know. Although there are many Arduinos and Arduino type products, I only have experience with the Arduino Uno Rev3. Likewise, the only Atmel microcontroller I know is the ATmega328P. A Little Background (well not so little) I have Atmel ATmega328P microcontrollers on two devices: An Arduino Uno (Rev
