some devastated regions in India.
Welcome to the 302 new subscribers we have this month.

Read this newsletter right through, believe me it is definitely worth it.
Your first name is recorded as: "Ian". If this is incorrect it can be remedied
here, BUT please copy and paste this email address to the form. The email

I certainly appreciate your participation in receiving my Newsletter.
a) Have you considered writing up that pet project of yours, maybe relate
your experiences constructing a project from a kit? Do you want to publicise
a project or a kit?
b) Have you considered joining our Electronics "Questions and Answers
This is a mutual help group with a very professional air about it. Not
for absolute newcomers to ask questions BUT an excellent learning resource
for newcomers, highly recommended.
a) Among the new pages I have added - for U.S.A. and Canadian residents
only, with a blatant commercial at the end. Suitable for an amateur radio
operator's family and business communication needs:
b) I'm progressively adding an easy "copy and paste" code near the bottom
of all my pages so you can link to my individual pages from within your
own site, if you choose to do so.
a) This is very important to YOU - so please listen up!
That stupid vandalistic "Snow White" virus still continues to rear its
ugly head everywhere and now even is mutating into French and Spanish versions.
This is the reason I will not allow attachments on "Electronics Q&A".
Here's a FREE virus checker from Computer Associates. I have NO connection
with them except for using their free product which automatically upgrades
itself every time I go on the net.
b) A trip through my book shop https://www.electronics-tutorials.com/book-shop.htm
would be of assistance to me if you DO decide to update your reference
books. Worth a thought AND a look.
Some excellent titles here including a couple by our old friend Bill Orr,
W6SAI who sadly passed away last week. What an absolute loss!.
c) In particular, this book was highly recommended to me.
"Microelectronic Circuits" by Adel Sedra and Kenneth Smith - thank you
c) See my concerns about "throw away" email addresses at the end.
Longer subscribers know my site has been submitted to the technical committee
of the PirelliAward 2000 which provides for a first prize of 25,000 Euros
($US 23,000) and a trip to Rome in March/April for the prize winners.
Nearly 700 entries were nominated and the technical committee have reduced
this down to 200 entries for contributions to "scientific culture".
I am optimistic I have been included in that number of 200 semi-finalists.
The next step is to further reduce this number down to 40 "finalists" for
submission to a jury from which the winners will be selected. I am not
so optimistic about this last step.
Under the conditions, considerable points emphasis is given to multimedia
work including sound, animation etc. and of course my site has none of
However, fingers crossed. Should know in about four weeks.
I said I would do a monthly "spotlight" on a subscriber. It is appropriate
I chose one of the earliest subscribers first off, a quite remarkable young
man as you will see. In his own words.
"Hi, I'm Dan Bartlett, VK4TDB - I have been a licenced amateur since June
1999, at the age of 14. In May 2000, I upgraded to VK4TDB, and I am now
considering using my Amateur licence as part of an in-school TAFE course
(as my 16th birthday is in about 4-5 wks).
I am the editor of StuckButton, a free online magazine for amateur radio
enthusiasts, which is available from http://www.egroups.com/group/stuckbutton.
As the next issue will be coming out on March one, articles are appreciated."

I didn't see anything particuarly interesting.
From David N2ZHY. May or may not be of interest. about Internet phone.
Haven't had a chance to check it out.
Have you come across any useful downloads? Let me know, I may include it.
I asked. Nobody submitted anything to me.
a) Easy Printed Circuit Board Fabrication, Using Laser Printer Toner Transfer.
You can easily make your own high-quality PCBs (printed circuit boards),
from a laser-printer or copier printout of the desired copper pattern,
using an ordinary clothes iron, and the correct paper type.
b) How are semiconductors made? - by Harris
Strictly speaking this tutorial presented by Harris Semiconductor applies
more to integrated circuits but the principle remains much the same. The
process of manufacturing semiconductors, or integrated circuits (commonly
called ICs, or chips) typically consists of more than a hundred steps,
during which hundreds of copies of an integrated circuit are formed on
a single wafer.
c) Dr. Matrix' Web World of Science -
OK I get a mention in there somewhere but good surfing.
d) Recent Earthquakes in California and Nevada - updated hourly
In the light of recent tragedies I found this site particularly interesting,
especially being updated hourly.
Students make First Contact with the International Space Station
January 30, 2001 -- The days of painting Styrofoam planets are probably
numbered at the Luther Burbank School in southwest Chicago after students
there received a call from space. No it wasn't E.T.
NET AT RISK
CERT, the Computer Emergency Research Centre, today warned of basic security
flaws in the Internet it calls "a potential disaster." It says most Web
sites and email are at risk because of four flaws in the BIND software
that runs the Net's Domain Name Servers. Worst-case scenarios:
hijacked email and Websites, and huge chunks of the Net disabled and unreachable.
THINGS TO PONDER - from Adam, N7YA
1. Why do banks charge you a "non-sufficient funds fee" on money they
already know you don't have?
2. Why do you press harder on a remote control when you know the battery
3. If it's zero degrees outside today and it's supposed to be twice as
cold tomorrow, how cold is it going to be?
4. Isn't Disney World a people trap operated by a mouse?
5. If the universe is everything, and scientists say that the universe
is expanding, what is it expanding into?
6. If you got into a taxi and the driver started driving backward, would
the taxi driver end up owing you money? (I've tried it, it doesn't work)
7. If vegetarians eat vegetables, what do humanitarians eat?
8. When I erase a word with a pencil, where does it go?
9. Why do they call it the Department of Interior when they are in charge
of everything outdoors?
10. Why doesn't glue stick to the inside of the bottle?
11. Is boneless chicken considered to be an invertebrate?
12. Sooner or later, doesn't EVERYONE stop smoking?
ON THE LIGHTER SIDE - from Tom K8CZ, another mate!
A blonde decided she needed something new and different for a winter hobby.
She went to the bookstore and bought every book she could find on ice fishing.
For weeks she read and studied every book, hoping to become an expert in
the field. Finally she decided she knew enough, and out she went for her
first ice fishing trip.
She carefully gathered up and packed all the tools and equipment needed
for the excursion. Each piece of equipment had its own special place in
When she got to the ice, she found a quiet little area, placed her padded
stool, and carefully laid out her tools. Just as she was about to make
her first cut into the ice, a booming voice from the sky bellowed, "There
are no fish under the ice!"
Startled, the blonde grabbed up all her belongings, moved further along
the ice, poured some hot chocolate from her thermos, and started to cut
a new hole. Again the voice from above bellowed, "There are no fish under
Amazed, the blonde wasn't quite sure what to do, as this certainly wasn't
covered in any of her books. She packed up her gear and moved to the far
side of the ice. Once there, she stopped for a few moments to regain her
calm. Then she was extremely careful to set everything up perfectly --
tools in the right place, chair positioned just so, everything.
Just as she was about to cut this new hole, the voice came again, "There
are no fish under the ice!"
Petrified, the blonde looked skyward and asked "Is that you Lord?"
The voice boomed back, "No, this is the manager of the skating rink!"
