Query: Easy to read...Hard to build...

Yes it's a good (not very) book...but isn't the best...Unfortunatly Mr. Iannini guesses that every one has the chance to get all the necessary materials to build the electronic gadgets...but in fact it cost a lot of money to build the gadgets he describes. There is a lot of more intelligent books to chose from. Don't waste your money.
