Gordon McComb's Gadgeteer's Goldmine! : 55 Space-Age Projects

Summary: flawed but still pretty cool
Review: At first glance, this book seems to be a necessary addition to the average tinkerer's library. However, after purchasing the book I found little inconsistencies between the schematics and the text, typos, or something else which led to confusion and apprehension--as the book starts out by warning of the risk of death with most of the projects if the instructions and safety precautions aren't followed exactly, and repeats the warning with almost every project. Before buying this book I'd suggest becoming very familiar with high-voltage circuits (to the point where you can design your own), otherwise you won't get as much out of it as you should. For example, the first project I tried was the variable xenon strobe, because I found all the parts in a $3.50 kit online, and it's actually two projects in one. The first thing I noticed before building it was that the parts list (the book lists all the components you'll need to build each project) didn't match the schematic--the 555 IC isn't listed. The text says it's the heart of the circuit. Not a big deal, but then the text refers to a third diode, which is neither in the parts list nor the schematic. If this is a necessary part you could blow other components and/or, as the book warns you several times, kill yourself. As an intermediate-level "gadgeteer," I can't figure out if the text is wrong or if the schematic is wrong, and if the schematic is wrong (the text sounds correct) what to do about it. This book isn't really to teach how things work, it's more for an advanced gadgeteer to put his or her knowledge to use. There is a basic explanation of how each project works, but not to the point where you could go in not knowing anything and come away a rocket scientist. Overall I'd recommend this book only to an advanced gadgeteer, or someone who's very serious about learning these types of applications of high-voltage circuits. Once you do understand what's happening, though, this book shows you how to build the coolest things, either from scratch or by rewiring things you'd find at a junk shop, and for that, if you are at that level, I recommend it highly.

Summary: Great Gizmos!
Review: I love do-dads, thingamagigs and gizmos, and this book is just chuck full of them! Even better, the writer doesn't assume you're an utter moron, or that you have an advanced degree in Electrical Engineering. Fun and challanging, I highly recommend it.

Review: This book tells you how to build everything from a night vision scope to a "bug" which transmits sound. Any one who is interested in electronics should purchase this book.
