Do you want to be able to receive satellite images using nothing
but your computer, an old TV antenna, and a $20 USB stick? Now you
can. At last, the technology exists to turn your computer into a
super radio receiver, capable of tuning in to FM, shortwave,
amateur "ham," and even satellite frequencies, around the world and
above it. Listen to police, fire, and aircraft signals, both in the
clear and encoded. And with the book's advanced antenna design,
there's no limit to the signals you can receive. Combine your
desktop or laptop computer with easy-to-find, Software Defined
Radio (SDR) equipment, and tune in a wide range of signals in no
time at all. Then, go one step further by converting a Raspberry Pi
into your own dedicated SDR device. SDR USB dongles are usually
designed to receive and decode high-definition digital television
broadcasts, but the rising popularity of SDR has led to several of
these devices being specifically made for - and marketed to - the
software radio crowd. With step-by-step instructions, you'll have
no problem getting everything up and running on both Windows and
Linux. The antenna is the final piece in the SDR puzzle: Which
antenna do you use? What shape do you need? How big does it have to
be? And where do you point it? Get all the answers you need and
learn what's possible when it comes to picking out or building an
antenna. And if you're not particularly handy, don't worry. You can
use an old-school set of rabbit ear antennas without too much
modification. Discover the fun of this growing hobby and then open
your ears to the hidden signals that surround you. What You Need:
You will need a relatively recent computer or laptop, running
either Windows or Ubuntu Linux. You can also use a Raspberry Pi.
All of the software necessary is free and open-source, and the book
describes in detail where to get it and how to install it,
depending on your operating system.
The Raspberry Pi is a credit card-sized computer that plugs into
your TV and a keyboard. It is a capable little computer which can
be used in electronics projects, and for many of the things that
your desktop PC does, like spreadsheets, word processing, browsing
the internet, and playing games. It also plays high-definition
video. This book takes you step-by-step through many fun and
educational possibilities. Take advantage of several preloaded
programming languages. Use the Raspberry Pi with Arduino. Create
Internet-connected projects. Play with multimedia. With Raspberry
Pi, you can do all of this and more.
Learn how to program your nifty new $35 computer to make a web
spider, a weather station, a media server, and more. This book
explores how to make a variety of fun and even useful projects,
from a web bot to search and download files to a toy to drive your
pets insane. Even if you're completely new to programming in
general, you'll see how easy it is to create a home security
system, an underwater photography system, an RC plane with a
camera, and even a near-space weather balloon with a camera. You'll
learn how to use Pi with Arduino as well as Pi with Gertboard, an
expansion board with an onboard ATmega microcontroller.Learn
Raspberry Pi Programming with Python has been fully updated in this
new edition to cover the features of the new boards. You'll learn
how to program in Python on your Raspberry Pi with hands-on
examples and fun projects. What You'll Learn Set up your new
Raspberry Pi Build unique projects across a range of interests
Program basic functions and processes using Python Who This Book Is
For Readers who want to learn Python on a fun platform like the Pi
and pick up some electronics skills along the way. No programming
or Linux skill required, but a little experience with Linux will be
helpful. Readers familiar with the 1st edition will enjoy the
updated information in this new edition.
Make a Raspberry-Pi Controlled Robot teaches you how to build a
capable and upgradeable personal robot for around $100. You'll
learn how to control servos, respond to sensor input, and know
where your bot is using GPS. You'll also learn many ways to connect
to your robot and send it instructions, from an SSH connection to
sending text messages from your phone.
Jumpstarting books provide an avenue for makers to quickly master
topical knowledge! Each book starts with instructions on how to
install or initialize the hardware or software needed to reach the
"Hello, World" stage of getting started! The second project in the
book builds on the first to use more of the hardware or software's
capabilities. Later projects expand the user's knowledge into
lesser-known aspects of the topic. All Jumpstarting projects are
for Makers -- they provide hands-on, real-world experience in
making the hardware or software do what you want it to do!
The micro:bit, a tiny computer being distributed by the BBC to
students all over the UK, is now available for anyone to purchase
and play with. Its small size and low power requirements make it an
ideal project platform for hobbyists and makers. You don't have to
be limited by the web-based programming solutions, however: the
hardware on the board is deceptively powerful, and this book will
teach you how to really harness the power of the micro:bit. You'll
learn about sensors, Bluetooth communications, and embedded
operating systems, and along the way you'll develop an
understanding of the next big thing in computers: the Internet of
Things.
