2. MY QUESTIONS?

After my interim newsletter following eight complaints I received a lot of letters of support. However nothing has changed in a practical sense except a further 32 people probably miscontrued what I said and unsubscribed. An additional 52 people subscribed in the next three days. A trip through my book shop http://www.electronics-tutorials.com/book-shop.htm so far produces minimal effect.

So reality dictates I MUST do something. This represents the best consensus of opinion. Please go there now and read it because present indications are there will only be two more of these newsletters:

3. PROJECTS IN PIPELINE

Actually this isn't mine nor is it in the pipeline. It's a project by Dieter "Diz", W8DIZ of the world famous "Flying Pigs" QRP group, licensed amateurs welcome to join provided you have a sense of humour and believe you can "do more with less".

RECEIVE AND TRANSMIT FROM 100 KHZ THROUGH 30 MHZ.

Variable or fixed (option) 4.9152 MHz band pass filter. Radio "system" will utilize band modules like the TenTec Scout. MC145151P2 PLL MAIN TUNE will double as a Signal Generator using a LMC662 and a LT1252 FREQ DISPLAY will double as a Frequency Counter.

This will be a very "MANUAL" radio INITIALLY Frequency sub-bands are set with dip switches. Each sub-band is 5 KHz to 40 KHz depending upon Main Band using a J309 VXO Reference Oscillator Main VCO using a J310 and 4-MV209 varactors tunes 2-30 MHz minimum VCO used a VN0106/2N7000 AGC loop, 5 watts out, fully adjustable SWR indicator and BALANCED/UNBALANCED ANTENNA Tuner optional.

Transmit function could be optional (Receive Only)

Completely modular, designed with the experimenter in mind. The Frequency counter/display is from AADE.

Ugly-Manhattan style construction throughout.

(optional) Built-in K1EL memory keyer - K10 chip with built-in Capacitive Touch Paddles
(optional) SWR indicator and BALANCED/UNBALANCED ANTENNA Tuner
The project is first of all constructed "ugly style".

4. THE PUBLIC ELECTRONICS CIRCUIT ARCHIVE - Daniel VK4TDB

The Public Electronics Circuit Archive (as I have called it), can be found:
http://www.publicelectronics.cjb.net.

According to Daniel: "It is a site where people can submit circuits for others to view/modify/construct. Everything is free-gratis, so everyone benefits".

"There are only a few circuits there at the moment, so I'm asking people to get out there and design! It doesn't matter how simple or complex they are, and I can help fix circuit diagrams if they are messy. All I need is the circuit, and a basic description of what it is and (possibly) how it works".

"There is also a Q&A and Ideas forum, where people can ask questions for others to answer, or add general electronics ideas (no matter what topic they are about)".

Clean Disk is a user-friendly utility designed to free up disk space by deleting temporary directories and other files, such as leftover, unneeded setup files. It is designed not to interfere with Windows or any another program.

c) SPUD - A potato powered web server - from Hugo Peeters in Belgium

Quote from site: "This is an actual potato-powered Web server, currently online here. After the great SpudServer joke, I thought it would be interesting to see what an actual server capable of running on potatoes would look like. This server is very, very slow (around 0.2 hits/second), so you may have trouble connecting".

See http://world.std.com/~fwhite/spud/

d) Traceroute

Traceroute, Ping, Domain Name Server (DNS) Lookup, WHOIS, DNS Records Lookup, and E-Mail relay Check.

10. HUMOUR AND INSPIRATION (by ever popular demand) -

A large two engined train was crossing America. After they had gone some distance one of the engines broke down. "No
problem," the engineer thought, and carried on at half power.

Farther on down the line, the other engine broke down, and the train came to a standstill.

The engineer decided he should inform the passengers about why the train had stopped, and made the following
announcement:

"Ladies and gentlemen, I have some good news and some bad news. The bad news is that both engines have failed, and we
will be stuck here for some time. The good news is that you decided to take the train and not fly."

AND

The service area was located on a main highway leading to the beach. The pump attendant was accustomed to seeing tired and sunburned occupants in the cars that pulled in to tank up.

When a rusty old station wagon containing a very tired looking couple and seven screaming children pulled into his station, the attendant tried small talk to cheer the occupants.

"Hope you had a good day at the beach! Nice looking kids there.

Are they all yours or is this a picnic?"

Wearily, the driver relied, "Yes they are all mine and it is NO picnic!"

AND

An old snake goes to see his Doctor. "Doc, I need something for my eyes, I can't see very well these days."

The Doc fixes him up with a pair of glasses and tells him to return in 2 weeks.

The snake comes back in 2 weeks and tells the doctor he's very depressed.

Doc asks, "What's the problem? Didn't the glasses help you?"

"The glasses are fine doc, but I just discovered I've been living with a garden hose the past 2 years!"
