5.0 out of 5 stars Surprisingly Complete, September 12, 2013
Verified Purchase(What's this?)
This review is from: Raspberry Pi Projects for the Evil Genius (Paperback)
Because the Pi is a fully functional PC on a little board, with many features (including multimedia!) in the class of Arduino and Propeller, most project books don't have the space to get into the basics of Pi, like loading the O/S and many other details. Since this is a UK unit, many of the websites (even though this is all open source) are a chore to sort out. Getting the free downloads shown in this book is worth the price of the book itself, DO NOT pay for the O/S on a site, it is free on many others, as shown in this fine little gem!

True to the evil genius series, this book is an exception to the completeness issue! Not only are the projects fully detailed, with carefully tested code that works without glitches, the author also takes the time to go over the basics of Pi as well, including getting up and running before the project phases. The book has something in it for everyone because of that, from beginners to advanced designers and hobbyists. As a roboticist and teacher, I'm using the Pi more and more in place of Arduino programs (called sketches) because the motor controls are much more like the most advanced robotics, which often use Linux. The Department of Defense uses Linux in some of their drones! VERY scalable system.

A great way to learn not only Pi, but electronics, programming and much more, from grade school to graduate engineer. And in case you're new to Pi, many folks are actually making the cheapest PC's on the planet with this little monster, INCLUDING HDTV interfaces for their monitors! The (non profit educational) Pi developers were smart enough to include multi media, which is amazing for a chip this size. If you want to go "big time" you can even combine it seamlessly pin to pin with Arduino for automation, or Propeller for multi processing. Highly Recommended.

I must disagree with your "carefully tested code that works without glitches" comment.

The code for the very first project is incomplete. It says to import the time library but never actually imports it. See below -

#import the time library to access the sleep function
#use the BCM pin numbering scheme as discussed earlier in the chapter
GPIO.setmode(GPIO.BCM)

Did you REALLY read and USE the code in this book? If you did this project would have failed miserably.

I have all the libraries and am a code developer so had no problem filling in the blanks. Do you REALLY do many of these PROJECTS yourself? They range from pseudocode (where you have to create, download or import from your libraries/plugins/templates ALL the code) to about as complete as this project, when only minor tinkering is needed. This depends on your skill level, and you're right, some like you might fail miserably, others might find it a breeze, and still others be in the middle. After trying hundreds of these projects, especially in robotic vision, this still ranks as one of the best. Most books and projects I review have numerous actual errors you need to fix-- I found this project to only have a few easily managed gaps that can be cured in numerous forums and stand by the review, but am thankful that you might be warning off folks that don't want to do a little work. --Angela
