5.0 out of 5 stars Tastes great and is fortified with B12, March 25, 2013
Verified Purchase(What's this?)
This review is from: Nutritional Yeast, 8 oz. (Misc.)
Nutritional yeast by itself does not contain vitamin B12, and it is not clear from the description whether this yeast has been fortified with B12. Here's a response from Barry Farms:

Here are the ingredients for the Nutri Yeast we carry.

Ing: Inactive Dried Yeast, Niacin(B3), Pyridoxine Hydrochloride(B6), Riboflavin(B2), Thiamine Hydrochloride(B1), Folic Acid(B9) and Cyanocobalamin(B12). All natural low heat dried nutritional yeast flakes are over 50% protein and are fortified with vitamins. They contain no additives of any kind other than the vitamins.

2.0 out of 5 stars Countdown timer is function is broken, October 10, 2012
Verified Purchase(What's this?)
The watch has a countdown timer. In three other Timex sports watches I've owned, once the timer runs down to zero, it can be reset back to its starting time with one press of a button and started again with another press. This is not the case for this watch.

Once the timer runs down to zero on this watch, you have to enter the "set" mode, then use "next" and "start/stop" buttons to navigate through digits and set them again, then exit the "set" mode and start the timer again.

Let's say you need a timer for 00:20:00, which is simple enough. You start the timer and 5 seconds later realize that you started it too early. You'd like to reset it back to 20 minutes. After pressing and holding "set" to get into the set mode, you have to press 9 buttons before you can restart the timer.

Button function names ("set", "start/stop", "mode", "indiglo") are written in an extremely small font. The decorative white tick marks are larger than the function names and show up more prominently than actual functionally important information.

4.0 out of 5 stars Great source of practical knowledge and rules of thumb, January 8, 2008
Verified Purchase(What's this?)
As other reviewers have already pointed out this book is a great source of practical design information that is not covered in engineering theory courses. One can read and re-read chapters highlighting great rules of thumb that apply to every-day design challenges. The book is really a must-have reference for any circuit/PCB/product designer.

That said, I have to suggestions to improve the book:

1. Analog domain is covered very well in this book, but the chapter on digital circuits is lacking in several important areas in my opinion.

a. I2C and SPI interfaces should be included alongside RS232, CAN and USB interface descriptions. Trade-offs of using I2C and SPI should be highlighted.

b. Digital interface timing parameters like setup, hold, edge rate, etc. should at least be mentioned. Here's why:

c. A discussion of digital bus topologies as it relates to timing parameters and PCB layout should be discussed. How to connect a multi-device bus, and make sure it satisfies interface timing specifications? Discuss star and daisy-chain topologies for layout. Fan-out and loading are already covered, but add examples of how those derate timing parameters on a shared bus.

2. The book is called a "companion". Unfortunately, in my experience the book's construction does not stand up to even moderate use. Sections of pages in my book have separated from the binding.

For someone thinking about buying the book these criticisms should not be taken alone. I chose not to cover all the wonderful parts of this book because other reviews here do a great job of it. I would not hesitate to recommend this insightful and well-written reference to anyone looking to improve their practical electronics design knowledge or to refresh skills lost to memory.

3.0 out of 5 stars Not a bad product once CD media loads, July 27, 2005
Verified Purchase(What's this?)
I bought this program so that I can plot road bike routes and generate elevation profiles of those routes. The Back Roads Explorer does that well if the route is entered by tracing on the map with the mouse. The profiles are generated well and there is a link from the profile back to the map; clicking on the profile will put a marker on the map route, which will tell you where to expect that big climb. Map and elevation profile can then be exported to an image (JPG, GIF, etc.) file or printed out or stored to a PDA. Beware, there is no way to automatically generate directions from the route.

One of the reasons for a three-star rating is that the CD media was somehow incompatible with my CD drive. It took several tries just to install the program. After that it would take a very long time to load data from map CDs. The program would sometimes freeze and had to be restarted. It would freeze 100% of the time if my route required data CDs to be switched. To fix this I had to copy National Geographic CDs to the hard drive (which took multiple attempts because of CD read errors) and burn it on CDR media.

Another reason for three stars is that the GPS route import is very rudimentary. It may work better when the GPS unit is connected directly to the computer (I haven't tried), but only text file format is supported by file import tool. The text file format is arbitrary and may not directly import into the Back Roads Explorer. In my case, it will not directly import the text file generated by Garmin eTrex.
