The factory closed because the CRT market is in decline, that was
expected. It has got nothing to do with them not being able to compete,
they have been doing that sucessfully for a very long time.

no it closed because it was unable to compete, were it able to compete it
would have been re-tooled for flat screens, or PVRs or some other new
consumer product.

Actually it was able to compete with *large screen CRT's* only because of
the shipping and handling costs involved with such items.
No Australian company can compete with China for small mass produced
items,
regardless of little Johnny's attempts at forcing a similar wage and
conditions structure here.

MrT.

 

[David, not to be confused]

It was able to compete just fine for large screen CRTs, and it did that
for many decades.
If CRTs were still as popular then it would not have closed.
The factory was only set up for large screen CRTs, it would have
required a completely new factory entirely for any other product.
Being able to compete *from scratch* with a different product is an
entirely seperate issue, that is not why they closed. Panasonic is not
an Australian company, so I'm sure there are other very good (internal
political) reasons why they would not set up a flat screen factory in
Australia.

Dave

The decision was dictated purely by the economics
and logistics of building flat panel display products.

With respect to Asia, FPDs (the screen themselves
along with the lamps, drivers and associated pixel
driving/decoding intelligence) are only built in a
handful of OEM factories.

It is monumentally expensive to set up a production facility
for the panels, plus quality control is crucial (far higher
than for CRTs), so fewer panel production plants allow
for concentration and more efficient use of resources.

These FPDs are shipped as kits and then turned into
the various TVs and similar apparatus by adding PSU,
tuner modules, I/O and audio stages, user interface
modules and the enclosure to form a finished product.

FPD's form most of the bulk and weight in a LCD or
Plasma TV set. To ship these down to Australia, along
with the re-tooling and re-equipping of plant would
have provided little return on investment, since the market
here is tiny compared to the rest of the big consumers.

Plus all of this investment will economically supply only
the AU/NZ/Pacific region. Export of the finished product
is uneconomic because most of the weight and bulk
has been imported in the first place - so it costs twice
as much in freight. Labour costs are not as big a factor as
people may think since automated production and goods
handling systems takes care of most of the labour.

Singapore is a good choice for an assembly plant.
It forms a regional hub, whereas AU is really an end-of-
the-line location. Raw materials, components and sub-
assemblies can flow into and back out of SNG with very
little cost impost. Land and labour can be (relatively) cheaply
sourced from Malaysia, plus SNG is already an established
shipping point for the Oceania region, the EU and the rest
of Asia. It is cheaper to ship from SNG to Perth and northern
Australia than to do so from Sydney or Melbourne.

Folks,

Looking for a cheap data-logger for recording DC volts(0-40) on a
remote site. I'm not looking for anything fancy, but I'd prefer a
reasonable memory and USB port. Weatherproof would be nice, but not
essential.

I'd prefer ready-to-go models, but would consider something that
requires (minimal) work to set up.

Any ideas appreciated.

Whats the required sample rate, ie How many readings per sec or minute ?

And

How many samples or what period do you want it to record ?

And

Do you need a trigger input,
ie. Only start logging if input voltage is between a certain range
or exceeds a certain value ?

And it might also be of interest to know how long the device
will be in the field before its re-acquired, though these days
that is not as much an issue as it can power down and retain
in non-volatile memory etc.

What are the environmental conditions, will it be in the sun
in the middle of the day or subject to moisture, splashed etc ?

The market for crts is drying up. There's no point in making something en mass
that nobody is going to buy. The market is going for plasma and lcd screens,
something the Panasonic factory was not geared to produce, and would be
very expensive to setup for production and testing of flat panel displays.

They are setting up in Singapore for another reason, not directly associated
with producing flat panel displays. You can read about it here

Hey I need to conduct 12VDC @ 130 AMP over 300-400m with minimal loss
and expense.(we all need to do this right?)
I have discovered that I may need some seriously heavy duty cable for
my power station.

Basics are understood that DC was no good for long runs therefore AC is
used.
7 to 12 miles for DC dose not ring bells!?

Questions:
Is It dumb to try to transport DC over such a distance?
What loss can I expect provided I can find a matching cable specific to
my requirments.?roughly(have been googling,but looking for been there
opinions)

What Cable has been used in the past for this type of
application......at a guess would it be right to assume,phone
cable?telegraph?amps rating? Old hydro cable?That copper cable they
used to run by the train tracks 20 years back?

Do I need to go 24VDC to get back to 12VDC at destination?(hate this
idea)

I can find 100amp cable in 100m rolls where do I look for bigger stuff
?

Finally is it worth AC over this distance?I would gather a similar
infustructure would need to be in place as with DC?

To tidy this up,what cable should I be looking at using?

Thanks in Advance

So what is it you are farming that you want the power for 24hrs/day and dont
want a big increase in your power consumption from the mains?

Sorry....couldn't resist with the OP's name

I just got the new 2006 Jaycar catalog (which is very good BTW, lots of
new stuff), and it's interesting to see them (on p9) respond to the
criticism about them turning to selling "gadgets" instead of
electronics parts.
As most of us have already figured out, they admittedly "have to have
the other stuff to pay the rent", but they are increasing their
electronics parts range to compensate.

Perhaps those who have bagged them in recent times will now understand.

I bagged them, and I've always understood. They sell that junk to make
money, very complex stuff.

Yes they are currently still very good on the electronic stuff, and yes some
of it *is* expanding. The point is that someday (probably if/when the chain
changes hands) a bean-counter is going to come in and work out which
products contribute a profit and which don't. The stuff that doesn't make
money will be turfed and as soon as you know it you'll have yet another
DSE/Tandy.

Furthermore I struggle to understand who (if anyone) buys those novelties.
They're on the shelf because they have an enormous margin, but I actually
never see anyone *buying* them ... and that includes my experience working
in electronics shops.

I personally didn't think they had anything to answer for, as I have
only seen the electronics parts range increase and get better every
year. If they have to sell gadgets to consumers to compensate then so
be it.

Thumbs up from me.

However
they argued that they sell almost none of that crap, and most of the
turnover of the stuff tends to be display items getting broken by the
aforementioned kids.

That matches my experience. And I don't think it's just the demographics.

I guess the margins make it all very attractive to market, and at the same
time if they end up with a product that's not selling there isn't much
impact as they depreciate or go on "clearance" because of the negligible
cost.

Thanks for the advice guys, I will look at the HOT and was going to replace
the electrolytics in the PS anyway as a preventative measure..

I'd still like to get hold of a schematic if anyone has one..

This monitor has the main power switch on the back with a "soft on/off"
switch on the front panel (I presume that's what relay RY901 does??) - the
"tic tic tic" sounds starts as soon as you switch on the main switch without
needing to push the front mounted button, so does this still sound like
possible HOT??

Thanks again everyone, and yes I'm aware of the dangerously high voltages
inside these things and the necessary precautions, I just don't have very
much experience with TV/Monitors and the like.

That's what I initially thought so checked for solder bridges, blobs,
dry joints, incorrect component placement, etc. Even replaced a number
of components including the IC and the output transistors in the
positive regulator stage. I don't think the PCB pads can't take much
more rework before lifting!

I tested the supply within the vincinity of other lights (incandescent
& fluro), and the fridge. The circuit seems very susceptible to mains
switching events.

Like I said in my original post though, the circuit works perfectly
with current limits of less than 2A, which is what I'll mainly use
anyway. If I want to use higher currents I might have to keep it away
from "highish-switch-on-current" appliances.

What might help me would be voltage measurements around the circuit
with the current limit set at 3A. The voltages given in the assembly
manual have the output set to 1A and voltage checks at this current
level were correct.

One question though, what is it about the fluro and fridge switching
that could be influencing the circuit? Is it the surge current in the
mains line, or the RF/EMF pulse, or what?
