This module acts as a tutorial to help users build a cluster of Nvidia Jetson TK1 cluster for Parallel Programming and Distributed Processing. The guide is a step by step procedure to build a 6 Node TK1 cluster with a shared network file system. Note that clusters can be of any length n≥2. Basic knowledge …
Monitoring 100 year old factory processes are hard, but it gets easier, safer and more reliable with a Network of nRF24L01 RF transmitters. Story The modern factory process relies heavily on digital technology to monitor different parts of the facility. With digital technology, factories have become safer, more productive and easier to operate. This technology …

Once upon a time… So this is how this story began… The Raspberry Pi has fascinated us geeks from the time it was first announced. We were thrilled to hear that Eben will be presenting at WSO2Con, and even more thrilled when Sanjiva suggested that we should host the WSO2Con Conference App backend on a …

Introduction In this project, we shall build a 3-symbol Turing machine using 11 bicoloured LEDs to represent the cells on the tape. Green represents a 1, red represents a 0 and a blank is represented when the LED is off. We shall call these the tape LEDs. The middle LED is labelled with a tape …
Introduction The XMOS startKIT from Farnell (or Newark) is a very low cost (£12 including VAT) processor platform that works well with the Raspberry Pi. Together is possible to construct robotics applications with almost no soldering required. The XMOS startKIT is a near-credit-card sized board with an XMOS chip on it with multiple ‘XMOS cores’ …

The goal of this tutorial is to help you begin programming with Python to control your Arduino robots with a Raspberry PI. We will go over the basics like installation and some simple examples to control your robot from a Python GUI from Raspberry PI. Step 1: Parts list In this tutorial we are going to use the following …
Summary: In this Instructable we look at how to build more reliable computer systems using WatchDog timers. We show how to set up and use the Raspberry Pi and Arduino internal watchdog timers. We also explain why an external WatchDog Timer is a better choice in many, but not all, systems. See more on WatchDog …

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 …
