All computer DDR memory today have little I2C EEPROMs to store vendor, configuration and module spec information. This is done to allow computer to detect memory type, and configure memory interface to correct speeds and voltages according to module spec. This mechanism is based on JEDEC Serial presence detection specification (SPD) which is available for […]

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
