As someone who's never been too adept at science or really enjoyed it all that much, I got my first taste of sincere, scientific satisfaction when I swallowed up Sneakiest Uses. These little projects are so simple, and they work! Now I find I'm curious about the inner-workings of all kinds of things, and I'm just hoping my boyfriend doesn't catch me taking apart the microwave.

Adventures from the Technology Underground: Catapults, Pulsejets, Rail Guns, Flamethrowers, Tesla Coils, Air Cannons, and the Garage Warriors Who Love Them Review

I really wanted to like this book, but it's written in such a simplistic and unfocused way as to leave me very disappointed. The author barely scratches the surface of the many technologies/projects/events he covers, and I always felt cheated after finishing each chapter... thinking "That's IT?!"
Underground tech IS a very cool subject to write about, but the lack of information about the inner motivations and passions of these "garage warriors" leaves a glaring hole in the text. If you have a short attention span and hate to read long books, this book is easily absorbed in a few hours. This is NOT a deep exposition on underground tech; it is a quick overview for newbies. Considering that the audience for this subject would be (I assume) more literate that the national average, it's a shame that the writing seems to be limited to what a sixth-grader could easily digest.
I notice now that the price has now dropped to 10 bucks. At that price, it's more in line with the quantity/quantity of content provided, and could now be considered an "okay" value... just don't set your expectations too high. I know this was a fairly harsh review, but I really was disappointed that the amateurish quality of the writing didn't live up to the slick cover design. Don't judge a book by it's cover!

Mr. Iannini continues the tradition he began in his first "Electronic Gadgets" book by offering up more than a fair share of laser devices. For this reason alone I don't think it is a good idea for your high schooler to play around with building the devices in this book unsupervised. Then there are the devices such as the "Marx Generator", which is a clever way of charging a number of capacitors in parallel, then discharging them in series. Originally described by E. Marx in 1924, Marx generators are probably the most common way of generating high voltage impulses for testing when the voltage level required is higher than available charging supply voltages. Again, this is another high voltage device which along with the Tesla coil and 400K volt DC generator can be potentially dangerous. The third category of projects that require adult supervision are those that invade the personal space/privacy of others - i.e. adults should always be on hand to explain why it is not OK to nauseate, confuse, and snoop on others for the purpose of learning electronics. The projects are interesting, but the reader/hobbyist should be an adult who is already knowledgeable of electronics and electronic construction techniques. The instructions in this book are not detailed enough for the novice. Also, the price tag on most of the devices is greater than $100, so they are not cheap either. Finally, and most importantly, the reader should have a penchant for safety. Thus if you want to get your teenager interested in electronics via interesting "cool" projects, and you are already knowledgeable yourself and willing to do full-time supervision of the construction, this is probably a good book over which the two of you can both learn and bond. Amazon does not show the table of contents, so I do that here:
