RTL-SDR is a very cheap software defined radio that uses a TV tuner dongle based on the RTL2832U chipset. Essentially, this means that a cheap $20 TV tuner can be used as a computer based radio scanner. A scanner capability that would have cost hundreds of dollars just a few years ago.

In this post, I outline my logic, and some time my pasions, concerning the building of my Linux system. I list all the compoents selected and why I made that choice.

I found a comprehensive VT100 / xterm terminal emulator, integrated with a tunneled X server, that gives me a mobile display for the Raspberry Pi via my iPad.

What I do here is list some simple, proof of concept programs that I used to create a network with a Arduino and Raspberry Pi (RPi) using XBee radios.

In this post, I provide a python utility that can be used to configure and test Xbee radios. Its a command interpretors used to send AT Commands to the XBee with output is color coded to help distinguish user input, from XBee radio output, and from interpretors output.

In this article, I explore the different XBee Series 1 & 2 radios and illuminate the options of using each. A major point of consideration is the availability of software libraries for devloping code.

In this article, I explore the serial communication options supported by the Raspberry Pi, under what situations would you use them, and how do you use them.

I want the RPi to provide status via email, SMS, web updates, and so why not speech? This post show you how to get the speech synthesis utility Festival working on the Raspberry Pi.

I want to deliver sound from my Raspberry Pi’s (RPi) Audio Output 3.5mm jack This post shows you how to get audio out working on the Raspberry Pi.

I'm presently using Dropbox as a service for quick and easy movement of files between multiple PCs I use.  I would like the same on the Raspberry Pi, particularly for moving files from my PC to the RPi.
