Raspberry Pi for Secret Agents - Third Edition

Overview of this book

This book is for all mischievous Raspberry Pi owners who’d like to see their computer transform into a neat spy gadget to be used in a series of practical pranks and projects. No previous skills are required to follow along, and if you’re completely new to Linux, you’ll pick up much of the basics for free. We’ll help you set up your Raspberry Pi Zero, Raspberry Pi 2 and Raspberry Pi 3 and guide you through a number of pranks and secret agent techniques that are so inconspicuous yet high on mischief. You’ll learn how to configure your operating system for maximum mischief and start exploring audio, video, or Wi-Fi techniques. We’ll show you how to record, listen, or talk to people from a distance and how to set up your own phone network. Then, you’ll plug in your webcam and set up a motion detector with an alarm and find out what the other computers on your Wi-Fi network are up to. Once you’ve mastered the techniques, we’ll combine them with a battery pack and GPS for the ultimate off-road spy kit.

Files may also be accessed and modified through a regular web browser.

Unfortunately, the company behind Dropbox does not yet offer client software for the Raspberry Pi. Instead, we'll be using a bash script called Dropbox Uploader that works just as well, and is in some ways even more flexible than the native client:

  1. Start by signing up for a Dropbox account if you haven't already got one:

    It's free with a storage limit of 2 GB.

  2. Grab the latest Dropbox Uploader script from the developer's GitHub repository and put it in a convenient location:

  3. Next we need to give the script executable permission:

    pi@raspberrypi ~ $ sudo chmod +x
  4. Now we need...
