Sample copy of printed circuit board Oct 25, 2006
By E Bon
"book lion"
Here is a sample of a printed circuit board (parts placement layout) that I found inside this new book. This one is the 23rd circuit featured inside this book. The quality of the print, the design, and the layout is excellent. The use of professional CAD and graphic software is obvious. Nothing is hand drawn here. That is good. I like that. Following is an excerpt from the book about this particular circuit:
A highly reliable doorbell with "touch" switch can be easily constructed with few components. When the "touch" plate is touched by a finger, enough stray power line current is introduced into the transistor T1 so that it conducts. Succeeding transistors T2,T3,T4 also conduct and eventually trigger the doorbell (the bulb lights if one is installed).
The touch switch can be constructed from a copper plate, aluminum foil or similar metallic materials. The supply voltage can be between 6 and 12 volts. The standby current is around 6 mA. Obviously, the circuit can also be applied as an alarm device for metallic objects.
This is interesting for me. It is useful, simple to construct, and the printed circuit board layout is ready made. I just need to photocopy the layout and transfer it on my raw pcb. Super! The cover looks great too!

Highly recommended reference for hobbyists and profis alike Mar 11, 2007
By Steve Chen
"he who wants to know it all"
This reference book is good for anybody who wants to learn how to construct (and understand) some useful circuits. There is plenty of information and several important concepts are explained. Also, parts replacement options are written all throughout the book.
While the book may not be perfect (which book is?), anyone interested in electronics and take the time to do a little thinking will be pleased with how the material is presented.
Clean and clear schematics, clean pcb layouts, no hand drawings. Obviously, CAD programs were used in creating the design layouts.
Highly recommended.

Clean, clean, clean. Obviously, the authors and production staff did a good job.
I like it. Highly recommended.

 My son got an "A" in a school project Dec 25, 2007
By Dr. Wung
""the builder""
I bought this book for my son as he asked me to help him with a school science project. He was very excited upon receiving the copy and started building the audio amplifier circuit right away. After some trial and errors (he did wire lines wrongly), he finally made it working. You can never imagine how happy he was. The cream of it is that his teacher gave him an "A" for the project. I am very proud of him. He told me he wanted to become an electronic engineer someday.
I give this book five stars for being a great help to my son.
