Well, you could try having a read of this one. I know it's a 'popular press'
article and there will of course be people who immediately scream that the
press are all liars, but I think that the basic figures quoted, and some of
the reasons that that are stated for the evangelical take up of this
technology, are probably thereabouts on the money, as I have read similar
ones elsewhere

I'd like to see the numbers on that. That's a huge loss.

The article doesn't seem stupid or self-serving, but it misses the
fundamental issue -- how much does wind energy actually /cost/, over the
lifetime of the generator? This seems to me much more important than how
efficient the devices are.

You better believe that they've gone up ! Massively so, because we now seem
to buy all of our gas from energy companies in France, who charge us what
they like. They are, in turn, buying it from the Russians.

All of what you say about your friend in America, duly noted. However, all
it says is that the panels that he put up, were basically all about winning
grants, tax breaks, and subsidies, rather than about the green issue, and
this seems to be the case for most of these alternative technologies. There
was a big debate about all of this 'PV panels on the roof' stuff recently on
another group, and some very well informed people on there did a good job of
taking the figures apart. The bottom line seemed to be that this four year
figure is the one that's always quoted, but due to such things as the
efficiency of the panels dropping for various electrical and physical
reasons, it is almost impossible to achieve the figures that the companies
would try to have you believe. We are now getting a leaflet a week dropping
through the door, trying to convince us to invest in this. Seems that many
of the companies springing up to carry out this work, are basically
untrained, and there is no requirement for them to be. There have apparently
already been cases of panels being installed on roofs that are not strong
enough to carry them ...

I would put them offshore, and protect them with a military presence and gun
batteries. After all, we had the technology to build forts out at sea in
Victorian times, so I'm sure we could do it again for nuclear power plants.
Use the water for direct cooling, as well ...

Food prices go up and down, depending on fuel costs. We have idiots
that want to more than double the current prices. That will more than
triple food prices, and cost a lot of jobs.

I saw 'bone in' uncooked hams for $1.19 a pound yesterday at a
Save-A-Lot store. A family of four caould have a nice Thanksgiving meal
for $20 to $30 and have plenty of leftovers for snacks. The problem
with a lot of people is that they won't look for good prices, or drive
an extra couple miles to save money on food. I shop at six different
supermarkets and at Sam's Club. I don't make a special trip to them
when I can avoid it. I stop in when I have other business in that
area. They are all concentrated in two areas, so I can shop more than
one in a single trip. I am diabetic, and have trouble finding what I
want, and can eat so I can'tt shop in one place.

Most people I know pick one store and buy everthing there, regardless
of prices.

The difference in prices among stores -- for exactly the same product -- can
be startling. In the Seattle area, Fred Meyer tends to have the lowest
prices among the major chains, but (of course) Costco can be (and often is)
even lower -- though you don't have the selection, of course.

I occasionally stop by the Oroweat "day-old" store and pay /half/ what I do
at Costco. I rarely pay more than $1.20 for a loaf of rye bread, or $1 for a
box of English muffins -- often less.

I remember some TV show where people were showing how they shopped. One
woman put more than $100 of food in her cart -- then said she didn't have
anything for that night's meal.

Most people have /no idea whatever/ how to make intelligent purchases.

Your whole argument is based upon the ability to travel to different stores
and buy different but similar things.

For example, you mentioned buying day old bread. It's similar to fresh bread,
but not the same. Or that brand X meat is the same as brand Y and so on.

If gas is cheap and you have plenty of time you can do it, but if you are
busy, don't have a car, or can't afford the gasoline, you are stuck.

Yes, of course. Where I live, this is absolutely trivial.

Actually, it's identical. Most of the items in Oroweat (and similar) stores
have been pulled shortly before their expiration date -- which is itself
conservative. It's not stale or moldy. No one could tell the difference.

> Or that brand X meat is the same as brand Y and so on.

I didn't say that! I said identical items, and I meant it. You wouldn't
believe some of the price differences.

Not necessarily. Most stores have weekly ads showing specials, and Websites
listing prices. I live within easy walking distance of two major chains
(Safeway and Albertsons -- there used to be a third, QFC), and Fred Meyer is
a hop down the road.

In the US, most people living outside cities have access to multiple grocery
stores at "reasonable" distances. (Within cities, you often have a similar
choice in the "better" neighborhoods.) Furthermore, the money saved by
making a single trip with stops at multiple stores outweighs the cost of
gasoline several times over -- sometimes many times.

You read the ads, think about what you want to buy, and make a single trip
to pick it all up. It's that simple.

For the past 50 years, the US has been becoming one huge "suburb". You're
rarely more than a few miles from /anything/ you want to buy.

I could almost believe it, just thinking about hysteresis losses in

The last Alberson's in my area closed a couple years ago. It had the
highest prices of any supermarket, so most of the customers lived within
walking distance.

We have:

Aldi
Publix
Save-A-Lot
Sweetbay
Wal-mart
Winn-Dixie

K-mart and Target have grocery sections, but the selection is
limited. We also have a huge liquidator that buys tractor trailer loads
of food and anything else you can imagine. At times they have full
cases of food that just hit the expiration date for $1. A few months
ago I bought five, four pound boxes of TUC peppered Crackers for $5. I
gave one away, and only have one full box left. 12 bottles of lime
juice for $1, and other deals show up, as well. The dates on the food
is actually a 'best used by' date, not a date it becomes unsafe.

Both of the 'day old stores here are gone. One went too retail
operation, the other closed when it was bought by a larger bakery. A
lot of what they sold was overstock, and not day old. I know there is
one about 15 miles from here, but that isn't worth the drive, unless I
need a lot of bread. It is near the new VA clinic, though, and I am
waiting to get on the transfer list.

I have days like that, because some stops are to restock the basics
instead of buying things for that day, but it rarely ever passes $50. I
only shop a few times a month for most things, as well. Canned foods
are bought by the case, spices and some other items are restaurant sized
containers Why pay $1.99 for 3.75 ounces of black pepper, when I can
get 80 ounces for $18.88? That is 21.33 times the weight for 9.48 times
he price. It also makes it easy not to run out in the middle of
preparing a meal. :)

I also have the problem of not being hungry while shopping and not
finding anything I want to eat that night, while shopping. Diabetes
plays hell with your appetite, and the medicine to treat it is worse.

And I would have thought that you would have known me better than to
disregard something that I have taken the trouble to say, as being nothing
more than nonsense. No matter what you might think, the case for manmade
global warming is by no means made, and there are many scientists with an
alternative view. Some actually use real science, instead of media driven
pseudo science, to investigate the possibility that the trends are actually
the reverse of what the mm global warmingists would have us all believe.

Nobody disputes that we cannot continue using the fuels that we currently
do, to generate electricity. However, we already have a perfectly adequate
'alternative' to fossil fuels in nuclear. All it needs is for people to lose
their unfounded and hysterical fears of the technology, which are created in
no small part by media hype, and a vociferous anti-nuclear brigade.

QFC is Kroger's "high-end" store in the Seattle area. (Kroger's bought Fred
Meyer a few years ago.) The QFC near me was rather small, so when the
economy got tight, it wasn't surprising it shut down.

If any of your stores are owned by Kroger's, try the Kroger's brand raisins.
Beat the heck out of Sunsweet -- taste just as good, and are softer.

That's why it so surprised me, as you're normally a thoughtful person.

Scientists are only slightly more rational than the average person. Like
most humans, they tend to believe what they want to believe. However, as
carbon dioxide and methane are greenhouse gases, it's hard to believe that
pumping them into the atmosphere /doesn't/ have an effect. That is not, per
se, pseudo science.

It's interesting to note that the (so-called) Little Ice Age ended around
the time the industrial revolution got under way. Was this a coincidence, or
cause and effect? It is possible that part, or all, of the warming we see is
actually a reversal of the Little Ice Age.

The media didn't start the claims of manmade global warning -- they merely
(tend to) follow the opinions of whoever has the microphone, so to speak.

I think the "vociferous anti-nuclear brigade" has a very strong case. Of
course, the two major nuclear disasters were not caused by the technology,
per se, but by the idiots running the plants. Nevertheless... Mr Murphy is
still alive and kicking.

Do a search for "pebble bed reactor" and see what you think. It appears to
be a complete solution to the problems of nuclear energy. So, naturally, no
one is doing much about it.

It's not all media fueled hype. Some of it is very well deserved.

http://en.wikipedia.org/wiki/Hanford_Site

I'm reminded of an episode of the Simpsons where Mayor Quimby is
showing off the new alert sign in front of the nuclear power plant.
When it gets to stage 4 "Run for your lives" Homer remarks, "That'll
never happen." When questioned by a co-worker if he felt that the
site was safe Homer replied, "No, just that if the core melts, there
won't be any electricity to run the sign."

The biggest hurdle to overcome with safe nuclear energy is the age
old problem of "Who's guarding the guardians?"

If the debacle with British Petroleum and the government agencies
that were supposed to over see what was being done is any indication,
I'd rather not have to "trust" my government to make sure things are
safe.

Wrong on so many counts that it is laughable. SMT devices require new
techniques. ONE example of many similar events. About a year ago I
obtained a 'dead' 50" plasma TV. Plug it in, it tries to turn on,
then the red light on the front panel starts flashing 2 short, 1 long.
Download the service manual (free from Elektrotanya.com), it's
flashing error 12; problem with the 12V supply. Read the service
manual. 12V error may be due to a problem with the audio amp or with
the DC-DC converter. Disconnect the audio amp, no change. Read more
of the service manual. Overloading the 12V supply by the DC-DC
converter may be due to shorted mosfets. In that case, replace both
the mosfets and the controller, all are SMD parts. (The DC-DC-
converter is part of the Small Signal Board, available online for
under $100).

Order the parts from Digikey, for a total cost of less than $10,
including shipping. Use Chipquick and a soldering iron to remove the
old parts, solder braid to remove the old solder and Chipquick,
install the new parts. Reassemble the TV, cross my fingers, plug it
in. It turns on and works perfectly. Just for luck I verify all
power supply voltages and update it to the latest firmware.

The biggest problem was moving the 100 lb + monster around.

I've said this repeatedly, new technology requires new techniques.
The people who claim it's unrepairable either have a vested interest
in selling a new one or are incompetent.

I agree that this is not for the timid, but it's certainly still
possible to do useful repairs. What the manifesto is about is the
attitude, policy, design, and conspiracies of the manufacturers to
intentionally prevent users from fixing their gadgets, often for no
better reason than to sell more replacement devices. While the days
of user repairable devices seems to be shrinking, so are the days of
designed obsolescence and landfill fodder.

That's the problem. There's no reason for that to happen except the
greed and policy of the manufacturers.

>I'd love for it be so, by the way.

Ask yourself. Are you part of the solution or the problem? If you
think you're part of the solution, then do something that will make it
happen. A nasty letter or email to the public relations department of
your favorite eWaste destined supplier might be a useful start.
Purchasing repairable products might also be useful.

Incidentally, in 1983 I purchased a new pickup truck. On the original
order was a printed copy of the service manual. When the manual was
not forthcoming about 1 month later, I attempted to return the vehicle
to the dealer for failure to complete the transaction. I was serious.
I had no intention of purchasing a car that required the dealer to
repair. At 285,000 miles and 23 year later, I sold it without ever
having to deal with an "authorized" repair situation. Much of what I
currently own and use follows the same policies. I avoid buying
anything that I can't fix myself. It's not always possible, but given
a choice, it's high on my list of selection criteria.

>I detest sending stuff to landfills and
>to recycling centers.

Yep. However, a major source of spare parts for my repair biz is the
local recycler, so please continue to send stuff to the recyclers.

>But the truth is that there is not much inside a

I can handle SMT parts. It's not easy and does take both special
equipment (hot air SMT desoldering station and nozzles) and
considerable practice. I sometimes use a microscope. In my case, the
limiting factor is my failing eyesight. However, I'm lusting after a
USB microscope camera.

>Schematics are no longer
>obtainable.

<http://kythuatvitinh.com/forum.php>
<http://www.eserviceinfo.com>
etc. I have some nicely reverse engineered schematics of some popular
equipment. What I miss are the voltages and waveforms on the
schematic. I annotate mine whenever possible.

>Embedded software makes troubleshooting almost impossible.

Plugging into a JTAG port and hacking my way in is quite easy. That
port is designed specifically for development and troubleshooting and
often includes some tolerable diagnostics. There's usually a
password, which can be Googled or guessed.

>Repair parts are not available.

Have you looked on eBay? There are large numbers of parts and pieces
vendors selling cannibalized devices at often reasonable prices. I
have nothing against using used parts, but some of my customers don't
like it. So, I buy brand new parts from Chinese vendors.

>And the list goes on.

Don't forget badly conceived legislation regulating unscrupulous
repair shops and company policied forbidding employees from repairing
anything. Liability-R-Us and such.

>Richard Feynman (a Nobel winner) often talked about taking radios apart. If
>he would try that now, he would move on to biology.

True. What you're missing is that repair these days is rarely down to
the component level. Most often, it's by the board, module, or
sub-assembly level. These can be found and are usually easily
replaced. Repairing the individual modules, without the necessary
fixtures and test equipment is a problem.

The real problems are that these devices are not designed to be
repairable and are designed to be assembled, not disassembled. It
would not take much for a manufacturer to fix these, but it would
result in a slightly more expensive product. Perhaps if manufacturers
were required to deal with their own eWaste, they might reconsider
their policies.

I enjoyed this thread, especially the pranks.

Anyway, I too had worked on a few high power (1000 W) ARC lamp
supplies. The last had photofeedback unit that controlled
intensity. The intensity got lowered from a fixed level from the
feedback unit. The unit had a shutter, so the setpoints were
remembered when the lamp was off.

This photofeedback unit was designed in ahigh tech fashion. The light
was sampled with fiber optics at the last of the optical path. The
sensor temperature was controlled via a thermoelectric block.

Hello all,

I've got a customer's turntable here with a Shure M105E p-mount
cartridge in it. The stylus is fine, but the cartridge itself has an
open winding. I've seen this in Audio Technica and Grado cartridges
over the years, but never before in a Shure. Any chance you've got a
good body without a stylus you'd part with? (In the USA preferred. I'll
gladly pay shipping.)

Thanks!

Cue N. Cook with nonsense about opening up cartridge and repairing open
winding ... or at least endless speculation about *why* it failed ...

N. Cook obsession noted. And laughed until breathless at.
