VK2TIP IAN PURDIE'S MONTHLY NEWSLETTER FOR JUNE, 2001


Hi Ian,

Welcome to 217 new subscribers for the month.

Again, another "top" issue, please print it out. I'm sure you will be glad you did.

1. CORRECTIONS

See your personal details at the end. If these details are correct - DO NOTHING - otherwise:
http://www.electronics-tutorials.com/corrections.htm

~~~~~~~~~~~~~~~

1a. CORRECTIONS ONLY IF YOUR NAME IS 'BLANK'

We still have 277 people named 'Blank'. A great many did respond to the recent "wake up call", thanks mates.

After 30th June, I will certainly have to delete the remainder because clearly they don't read these newsletters (not even the jokes?).

~~~~~~~~~~~~~~~

I appreciate your participation in receiving my Newsletter, I most certainly do.

Please keep your email address current, nothing is so disappointing to me than having to needlessly delete about 40 odd 'undeliverable' emails from my precious list each month.

Same situation applies if you choose to use a "free" email address and you exceed your quota and, this letter bounces. Sorry but you're off the list, I've no other option available.

Those comments are unlikely to apply to @arrl.net, @qsl.net, @amsat.org or @ieee.org which are largely re-routed BUT certainly might apply to email repositories like @yahoo.com (the leader of bounces) or, @hotmail.com .

I am aware there are many people around the world with very limited ISP facilities and rely upon looking at their email at a free site through a browser.

~~~~~~~~~~~~~~~

2. MY QUESTIONS? b) The book shop:
http://www.electronics-tutorials.com/book-shop.htm
is still continuing to receive some attention. Please continue to do so.

c) Join our "electronics book of the month club". If you would like to join in with us...
mailto:bookclub@electronics-tutorials.com?subject=Book-of-the-month&body=!*EMAIL*!
We'll get it underway soon.

~~~~~~~~~~~~~~~

3. THE CHICKEN OR THE EGG?

Leaving no stone unturned in the pursuit of pure science, I unearthed this startling fact in answer to the age old question, "which came first, the chicken or the egg?".

I am reliably informed:

"Any fourth grade student would immediately recognize that egg laying reptiles were around long before birds evolved from reptiles, therefore the egg came before the chicken".

This of course now raises the next question, "which came first, the reptile or the egg?".

~~~~~~~~~~~~~~~

4. PHILIPS

Philips have been quite good to me over a great many years. Here's a list of very useful Philips related links.

a) Philips main site. Very useful in searching for a wide variety of data sheets, application notes and heaps of other good stuff.
See: http://www.semiconductors.philips.com

b) Another branch of Philips passive components.
See: http://www.acm.components.philips.com

c) Philips Ferrite technology. Applications information for signal processing, power conversion, EMI suppression
See: http://www.ferroxcube.com

d) FREE Data Handbook Soft Ferrites and Accessories - [PDF file 6.2 MB]

"This 848 page Handbook gives detailed technical data sheets and additional information about our complete range of Soft Ferrite Cores & Accessories and EMI-suppression products".
See:
http://www.ferroxcube.com/appl/info/ma01_200.pdf

5. SWITCHED MODE POWER SUPPLIES

Now, one of our subscribers is none other than Dr. Vincent G. Bello, PhD EE. Father of the Averaged SMPS SPICE Models, President of SPICE Simulations Co. and Power Electronics Analyst.

Vince has had a new book published (including diskette) "Circuit Simulation of Switching Regulators Using SPICE"

"A collection of 11 classic papers and numerous circuit & sub-circuit models developed by Dr. Vincent G. Bello and others, clearly showing how to use SPICE programs to simulate switching regulators for averaged state-space analysis following the mathematical models developed by Dr. R. D. Middlebrook. These papers develop in a clear and easy to understand way the basics upon which all SPICE models for averaged analysis depend. These SPICE models use only elementary components and easy to understand netlists which will run on any SPICE program. Without a clear understanding of these basics, it is practically impossible to understand the intricacies of today's complex schematic based models".

The book details can be viewed at:

http://www.ejbloom.com/shopfrm.php?type=book

You will find his book as selection 415 in the Circuit Modeling, Analysis, Testing & Thermal Design part of the book section.

[Note: I have no connection - merely highlighting one of our fellow subscribers and Vince's valuable work]

~~~~~~~~~~~~~~~

6. PROJECTS IN PIPELINE

a) I still have quite a long list in mind. Imagine if I had a budget comparable to electronic magazines to offer feature writers? But I DO have a long list!

b) I'm considering launching www.electronic-project.com later this year as a "registered subscriber only" site together with an accompanying "premium" issue newsletter.

What I'm hoping for is something like an online electronics magazine where the projects, including the how-to's, schematics, how-why it works, PCB layout as well as availability of the *kits* will be fully featured on the site www.electronic-project.com (not operational yet - still parked).

c) Another feature I'm considering implementing is a "news board" where you can post comments or opinions about individual items appearing in these newsletters. One example would be, being able to post a comment on b) immediately above.

8. UPDATES

I've slightly revised the layout of the main page although very few people arrive through the "front door". Of those who do so, a great many are "bookmarks" returning or from linked sites.

See: http://www.electronics-tutorials.com/

~~~~~~~~~~~~~~~

9. AN EXCELLENT ELECTRONICS MAGAZINE - entirely non-profit

~~~~~~~~~~~~~~~

10. DAMN "LIES AND STATISTICS"

The growth really fell in a hole during May..... , well sort of. Had to happen sooner or later I expect.

Although I was up to 1.30 a.m. this morning repairing broken links and other weird happenings, wonder if that had anything to do with it? I made a few changes which obviously backfired. I located an excellent free link checking tool to do all the hard work. As at the last day of the month:

Last month, May was 59,146 unique visitors (April 64,68) looking at a total of 172,644 page views (April 192,502) - New subscribers to this newsletter were of course 217, unsubscribes were a total of 18 (mostly named "Blank") and I had to delete around 44 "bounced" last month.

~~~~~~~~~~~~~~~

11. ANTIMATTER
  
Check out the Antimatter Space Propulsion group at Penn State for their interesting site on using antimatter to propel spacecraft. They've even designed an antimatter engine.
See:
http://www.engr.psu.edu/antimatter/

~~~~~~~~~~~~~~~

12. REAL COOL AND SOMETIMES FREE! DOWNLOADS - These are!

AND

"THE STRAIGHT DOPE ON FOOD, HEALTH, & EXERCISE":

Q:    I've heard that cardiovascular exercise can prolong life.  Is this true?

A:    Your heart is only good for so many beats, and that's it.  Everything wears out eventually.  Speeding up your heart will not make you live longer; that's like saying you can extend the life of your car by driving it faster.  Want to live longer?  Take a nap.

Q:    Should I cut down on meat and eat more fruits and vegetables?

A:    You must grasp logistical efficiencies.  What does a cow eat?  Hay and corn.  And what are these?  Vegetables.  So a steak is nothing more than an efficient mechanism of delivering vegetables to your system.  Need grain?  Eat chicken.  Beef is also a good source of field grass (green leafy vegetable).  And a pork chop can give you 100% of your recommended daily allowance of vegetable slop.

Q:    Is beer or wine bad for me?

A:    Look, it goes to the earlier point about fruits and vegetables.  As we all know, scientists divide everything in the world into three categories:  animal, mineral, and vegetable.  We all know that beer and wine are not animal, and they are not on the periodic table of elements, so that only leaves one thing, right?  My advice:  Have a burger and a beer and enjoy your liquid vegetables.

Q:    How can I calculate my body / fat ratio?

A:    Well, if you have a body, and you have body fat, your ratio is one to one.  If you have two bodies, your ratio is two to one, etc.

Q:    What are some of the advantages of participating in a regular exercise program?

A:    Can't think of a single one, sorry.  My philosophy is:  No Pain - Good.

Q:    If I stop smoking, will I live longer?

A:    Nope.  Smoking is a sign of individual expression and peace of mind.  If you stop, you'll probably stress yourself to death in record time.

Q:    Aren't fried foods bad for you?

A:    You're not listening.  Foods are fried these days in vegetable oil.  In fact, they're permeated in it.  How could getting more vegetables be bad for you?

Q:    What's the secret to healthy eating?

A:    Thicker gravy.

Q:    Will sit-ups help prevent me from getting a little soft around the middle?

A:    Definitely not!  When you exercise a muscle, it gets bigger.  You should only be doing sit-ups if you want a bigger stomach.

I hope this has cleared up any misconceptions you may have had.

Thanks to my friend Chuck...

AND as a bonus....

Atlanta, Georgia:

Scientists at the Center for Disease Control today confirmed that foot and mouth disease cannot be spread by Microsoft's Outlook e-mail application -- It is believed to be the first time the program has ever failed to propagate a major virus.

if you're still laughing please visit the next section, the newsletter must be worth it.
