Introduction If you’ve checked out my Rover project – an autonomous obstacle avoidance robot – you’ll know that I am a robot junkie. But my interest isn’t limited to wheeled vehicles. I have had a biped on the workbench for over a year but inevitably, whenever I turn my attention back to it, a brighter, […]
ZigBee Primer A ZigBee PAN (personal area network) is a self-organizing series of modems that communicate using the same protocol (based on the IEEE 802.15.4 standard). Individual modems are configured to play a specific role within the network. Coordinators establish and organize the network (there is only ever one coordinator in a network). End Devices

E-Book description: The world of microcontrollers and increasingly capable and popular small computing platforms is enabling many more people to learn, experience, and complete projects that would previously have required dedicated (and expensive) hardware. Rather than purchase a commercial or made-for-consumers kit, enterprising developers can now build their own solutions to meet their needs. Sensor

As with all DIY projects, one of the main hassles is the enclosure to put all of the hardware in. I wanted a quick solution – didn’t have the time to make something fancy. After a while I remembered that I’ve saved my Amazon Kindle Keyboard cardboard package. The quality of the cardboard is excellent
The first step in playing with a Raspberry Pi’s GPIO interface is to turn an LED on and off on command, the Hello World of digital electronics. As fun as that is, it would be more fun to do from my mobile phone using my home wireless network, this article runs through the software that

Problem We add a line entry to /etc/fstab when Raspberry Pi needs to automatically mount a network drive. The problem with this approach is that: Raspberry Pi needs to mount the network drive from the point of when booting up to shutting down. In other words, Raspberry Pi has to use CPU and RAM to

This tutorial will teach you how to create a network of cost effective, wireless sensor modules. Many of the ready-made wireless modules can be too expensive for use in multiple sensor units. While Wi-Fi and Zigbee modules are popular and easy to use, their cost can make their use in an array of sensors impractical.
