The Art of Electronics

This is a classic and one of my favorite books. Although dated it is packed with relevant information and is a great reference. 


the thoroughly revised and updated second edition of the hugely successful The Art of Electronics. Widely accepted as the authoritative text and reference on electronic circuit design, both analog and digital, this book revolutionized the teaching of electronics by emphasizing the methods actually used by circuit designers -- a combination of some basic laws, rules of thumb, and a large bag of tricks. The result is a largely nonmathematical treatment that encourages circuit intuition, brainstorming, and simplified calculations of circuit values and performance. The new Art of Electronics retains the feeling of informality and easy access that helped make the first edition so successful and popular. It is an ideal first textbook on electronics for scientists and engineers and an indispensable reference for anyone, professional or amateur, who works with electronic circuits.

Power Over Ethernet Interoperability Guide


A Complete Guide to Transmitting Electrical Power and Data over Ethernet Cables

Power over Ethernet Interoperability explains how to safely transmit DC power over an existing data network cabling structure so that separate AC electrical wiring is not needed to power up devices connected to the network. With a focus on cost-effective unshielded twisted pair (UTP) cables, this book provides proven methods for designing reliable Power over Ethernet (PoE) equipment and ensuring that it functions effectively. Details on the IEEE 802.3af/at standards and how various devices can operate from PoE are also contained in this practical resource.

Newnes Power Electronics Ultimate CD



Most engineers rely on a small core of books that are specifically targeted to their job responsibilities. These dog-eared volumes are used daily and considered essential. But budgets and space commonly limit just how many books can be added to your core library. 

The Newnes Power Electronics Ultimate CD solves this problem. It contains four of our best-selling titles, providing the "next level" of reference you will need for a fraction of the price of the hard-copy books purchased separately. The CD contains the complete PDF versions of the following Newnes titles: 

. Switching Power Supplies A to Z (Maniktala) 0750679700 
. Demystifying Switching Power Supplies (Mack) 0750674458 
. Power Suppy Cookbook, 2nd Edition (Brown)075067329X 
. Power Electronics Design (Sueker)

Troubleshooting Switching Power Converters: A Hands-on Guide





Power Supply design is all about detail. And a large part of that detail lies in the practical domain, largely because of the typically small number of microseconds of switching periods involved, and the even smaller tens of nanoseconds of switch transition times --- all these, in effect accentuating various "second-order" effects, that eventually end up playing prime havoc with "normal" expectations of how the circuit should behave. So not unsurprisingly, even after reading several books, most readers still find themselves no closer to the ultimate goal of designing an actual power supply. 

Sooner or later, all engineers start realizing the hard fact that designing a switching power supply isn't the trivial task it once seemed to be. But even after years of successfully mastering the underlying theory, the ultimate goal of creating a cost-effective, reliable and commercially viable power supply may still remain a distant dream, since success ultimately hinges on experience. That is, in fact, what clearly differentiates a senior and seasoned power supply engineer from the others --- the ability to navigate and surmount a veritable minefield of tricky issues that can only be learned the hard way, by actual hands-on experience on the job.

Jingyan MESR-100 ESR/low ohm meter review

I recently purchased a new ESR meter from a seller on E-bay called mib_instruments, their ebay store can be seen by clicking here and their website is www.mib-tech.com, where you read more about the company and see more of the test equipment they offer.

The  meter I purchased from this company was the Jingyan MESR-100 ESR/low ohm meter. The total cost was $59.99 including shipping. It took 12 days total for the unit to be delivered to me in the USA after being shipped from China, really quick I thought. The unit was shipped and I received tracking within 48 hours of purchase. The meter was very nicely packaged as you can see in the photos below.



  
This unit is really well made and is the best ESR meter I have seen in this price range. It has features I like from the other ESR meters together in one unit, toggle on off switch, banana jacks, battery compartment and a nice back lit LCD.






Click here to see the full specifications and features on MIB instruments website. 
                                   



 I will be using this meter daily to see how it holds up on the bench and out in the field with daily use and I will post an update in the next few months. Over all I really like this ESR meter so far and I would definitely recommend it. 

Please email any questions to contactus@preher-tech.com and also remember to vistit www.preher-tech.com.
