Admit it: you love to explore how things work. Screwdriver and pliers in hand, no castoff electronics or old appliances are safe. But once you’ve pulled apart your prey, do you really just want to screw it back together again . . . assuming you could? Unscrewed is the perfect resource for all UIYers—Undo It Yourselfers—looking to salvage hidden treasures or repurpose old junk. Author Ed Sobey will show you how to safely disassemble more than 50 devices, including: Laser Printer, Radio-Controlled Car, Zip Drive, Videocassette Recorder, Paper Shredder, Audiocassette Player, Electric Drill, Computer Mouse, Keyboard, Fax Machine, Joystick, Floppy Drive, Videocassette Camera, Electric Clock, and More! Each deconstruction project includes a “treasure cache” of the components to be found, a required tools list, and step-by-step instructions, with photos, on how to extract the working components. It also includes suggestions on how to repurpose your electronic finds. Why pay good money to an electronics store when you probably already have what you need in that old VCR, printer, or hair dryer? Fight the mindset of planned obsolescence—there’s technological gold in that there junk!

The concept is pretty good, I have long been a proponent of using parts from old junk to make or repair other things, but this book didn't make it. I have to admit it would be difficult to write a book that could show how to dismantle everything the reader might encounter. In this particular book the writer discusses vaguely how to take apart a few specific items. The information derived therefrom isn't enough for a novice to disassemble even the exact same items, and anyone who isn't a novice has already taken apart a sample of everything in the book. The pictures should have circles and arrows showing what screws to take out and where they are, not just '4 screws on the back' or 'cut the ribbon cable'. How many times does he write 'Lefty Loosens'? Too many times.The DVD player I took apart last night had at least 5 ribbon cables that had to come off before I could remove the main board, and they all could be released without cutting. The author doesn't bother to mention that the spindle motor of a DVD player or a CD player has a cool magnet on it, or that some older CD players have a laser diode that can be removed for use. He talks about how a reader might experiment with a LCD clock display to try to get it to display numbers, but doesn't even mention that there is a polarizing screen in front of the LCD display that can be removed and used, or that you could flip it over and change the polarity of the digits and background. Not to mention that these days an LCD alarm clock is likely to be so highly integrated that you can't disassociate the display from the rest of the electronics. I could go on but I think you get the picture.
