300 Electronic Projects for Inventors with tested circuits Kindle Edition

First, as many have mentioned, the writing is terrible even to the point where you cannot figure out what the author is trying to say. I’m pretty sure they wrote it in their native language and simply used google translate for the English version.Second, though it mentions having arduino projects, it has like 2 or 3, and they aren’t very good.As some have mentioned, much of this is gathered from the internet, where it is free. The photos of the circuits are blurred. Hard to read.Then too, many of the projects are duplicated with small changes, and impractical. How many water level sensors, burglar alarms, traffic light projects, hell…even a night watchman project to discover if the night watchman is at his station and not sleeping (which is kind of funny. You ring a telephone number to start the device and the night watchman has to shine his flashlight on a sensor to prove he is awake and at his station, but he also has circuits that can turn on a light in reaction to a sound, so a clever night watchman could build that, and go to a bar and it would shine the light for him. Also this problem is solved years ago, and how many of us have a night watchman?) it’s a hodgepodge. Can be fun to thumb through but again the text is often ridiculous and makes no sense, the projects most are banal and often cost more than commercial devices made for the same purpose, and many many inane “projects”. Skip this book.

I returned this after realizing most of the A.C. power was European. Nothing against that per se, but as an American hobbyist/inventor, it wasn't useful for my needs. I returned it.

I have been dabbling with electronics for a while now. I have been looking for a book that is concise and to the point on making small projects. In this book the diagrams are clear and easy to follow. I would love to see a book with more fun projects that have the next step up in difficulty. So that i can start working on bigger projects. This way i can start combining them to make larger devices that have more functions. With that i am verry pleased with this book. If anyone wants to get into electronics or you just want a hobby this is a great book to start with

The English translations are comically off, but the important language, the universal electronic language is crystal clear. If you're new to electronics, logic, schematics... You should keep this thing on the shelf until you've learned more. It is assuming you know at least the basics. But once you do know what you're looking at, you'll be amazed at all the possibilities offered by this book. Bravo! One of my favorites.

In general it is a good book. Yes, there are some mistakes but these errors are easily identified.

I fiddle around with electronic stuff and this has been an inspiration for my needs.

Very detailed book. Like a guidebook for those who need to know how to build a circuits. The author also provided many real life examples of how we can build circuits and incorporate in our daily lives such as alarm bell, door bell, burglar alarm and etc. Concise and easy to understand. A lot Of theories with practical examples.

I am a physicist that purchased this book for projects for my grandson. However, as a professional I am extremely disappointed in the author, this book is not about projects! First, most of the circuits will not function in the United States, as they are based on a 230 volt AC, 50 cycle power source. Secondly, this is a book of poorly reproduced copies of schematic circuits, with bad English blurbs stating “this circuit turns on a light “ ...End of Project ! This book contains 300 bad photos of other people’s schematics with no instructions, just a statement saying “this circuit does ‘this’”.... This book is someone’s idea of a get rich scheme.

Where to start? The English is poor, the introduction is basic such that if you need to read the introduction you will not understand the circuits and if you do understand the circuits you don't need the introduction.The circuits are all in different formats some with parts lists some without, I followed the link given on a watermark on one of the circuits and found a free web site with not just similar circuits but some are the same circuits.Having read through the introduction (because I am a beginner) the first circuit uses 230volts - dangerous for a beginner.My printed copy of the book was in black and white not the colour version shown on the amazon web site.There are better publications out there don't buy this one.I cannot understand how it gets around the copyright laws.

It's difficult to know who this book is written for. It starts by describing electronic components, how to read resistor values etc, all quite basic for the beginner. The text translation from Indian to English is appalling and only describes what the various circuits can be used for, not how they function. To have any understanding of how the circuits work and to be able to build them you need to be an electronics engineer. Some circuit diagrams do not relate to the text at all, some do not have component values either on the diagram or text, some diagrams are duplicated with different alleged functions. Many of the circuits are mains operated and should not be attempted by inexperienced constructors. On the plus side, the translation of text does cause a great deal of light hearted humour.Unless you are an experienced electronics engineer and can read and understand circuit diagrams you will find this book of little use.

Not only is the whole book written in atrocious English, but sometimes whole chunks of text seem to have been lost. The only reason I wouldn't return this book would be in the hope that some of the circuits do actually work !! I cannot believe that the book was even proof-read

Bad English. Black and white not colour. First mistake labels for megaohm M and milliohm also shown as M instead of m and 230 volt mains needed for beginner stupid. Diagrams don't match the words. Missing parts lists and componant values. Parts vary between blurb and pics schematics from various sources and poor quality. Norgate described as a nordoor. You need to be able to read circuits as some aren't labelled. Some projects very outdated or dangerous especially for beginners and that's just reading first 30 pages.

In my opinion this book is very poor. You are presented with circuit schematics with very little explanation and description, or what description there is often seems irrelevant, see the example of the photometer in the photo.Maybe this is a reference for people who are already expert in electronics but if you are not the you will find this of very limited use.
