Pegboard

09 June 2015

Over the weekend, I made some improvements in my hacklab with a new pegboard using 3D printed parts to organize tools that I frequently use while 3D printing and soldering. The pegboard is a 16x16 black plastic pegboard from Home Depot. These boards interconnect, so I can add more of them at a later point. The printed parts were all available on Thingiverse without modification.

XBee Radio Modes

22 September 2014

In a previous post, I wrote about the different XBee radio device types and how they can be grouped together to form a personal area network (PAN). This time, I will be focusing on the different modes that you can put your device into and how those modes can fit into your PAN. Just as last time, these categorization are larger based on the firmware that you load on to the device using X-CTU.

XBee Device Types and Network Topologies

17 September 2014

If you are interested in creating electronics projects with either Arduino or Raspberry-Pi, you may want to eventually add wireless communication to your projects. This is especially true with the advent of the Internet of Things (IoT). One way to achieve this is by using XBee radios. Digi is the manufacturer of XBee radios, but you can get them from many different suppliers such as Adafruit and Sparkfun. There are a staggering number of variations that these radios come in. This is because there are numerous network protocols (e.g. ZigBee or Wifi), and each of these variations come with various antenna options (e.g. wire antenna or PCB antenna). This article is specific to XBee Series 2 ZigBee Mesh radios (with any antenna).
