I had a quick look at the Software. 16F84 & 88 not listed. Poor translation
to English a bit of a worry

I was after advice on ones people have actually used & can recommend on that
basis, not only because they have a vested interest in the product.

You say the temp drops 92->85 (say) when the relay pulls in. If this is
the
result of the pull-in itself, as distinct from what the relay drives (i.e.
it is
related to a volt-drop issue etc) then the temp itself hasn't dropped

That's true, the temp has stayed the same.

- only
your reading has - and you need to have that masked with enough hysteresis
to
offset that "drop" plus an operating hysteresis.

The problem then is that big hysteresis will get in the way if the temp
really does drop from 92 to 85, I really need a more accurate measurement.

The 580s are a good phone, but I found them a little dull

There are a lot of people who think that for listening, they are exactly
right. If not, one can throw in a little eq - that is if you have some eq at
your disposal. Ever since we got the digital console at church, we've been
pulling eq out of service.

Isn't it better if things don't need eq? After all, you're adding
another component with its own measure of distortion.

The 595 has the same or greater neutrality, a
better soundstage and is more lively--also much easier to
drive.

That would be your personal opinon, which is of course yours to cherish. As
far as the easier to drive thing goes, 580s have a nice combination of
sensitivity and high impedance, and have to be the easiest headphones to
drive of the over a dozen that I have.

But not easier than the 580, which I owned. The 595 is much easier to
drive, and that's the old 120 ohm version. Senn have now switched to
50 ohms.

I'm assuming you're very familiar with the 595.

It is true that as much as Geology, ¨Physics; Meteorology, Economy etc ...

Tetanos in the last phase ... cure in 1 second flat, Polio in 2 days, and

out the other big shows I have disocvered in Australia ( like Rooney which I

say, although they know I have re-found and they have not been able to
re-find it again in 35 years " IT'S SO EVIDENT " ... and no gratitude nor

As well there is an easy way to curb the strenght of Ccyclones & Tornadoes
.....and an easy way to check the Toad and Termites plagues in Australia
....which I have found of course ... and very efficient & cheap too !
.... so just find it then !

.... but none of those things will be handed out to Mining Criminals,
Politicals Criminals and a whole nation which has supported such and support

the easiest although the one which gives only 3 hours warning, I have handed
out to Australia recently ! ... in anticipation of the Great Sydney Quake
likely to wipe out of existence some 500 000 Australians within a week now
!!!

Would you care to know how many replied and said Thank you Sir Turcaud for

NOT ONE !
Would you care to know how many thanks me for the huge Great Sandy Desert
Discoveries amounting to 250 Billions USD now for Telfer Mine alone ... and
potentially for the whole Paterson Range Mineral fields to over 1 000
Billions USD over the next 25 years ?
Two (2) persons alive now i.e. President Sheppard of the Australian
Prospectors 'Union and Dr Don Findlay who is in fact a Scottish Gentleman;
previous to those two gentlemen were late Attorney General Evans (Irish)
and Corporate Mining Prospector Berth Rutherford ( Scot) ... so when you
make the count only ONE Australian thank me for the Great Sandy Desert
Discoveries and this Bob Sheppard .....all the others took advantage of it
or insulted me in the most vicious fashion as recently Western Australia
Premier Geoff Gallop !

Given the circumstances and considering too that so many years have elapsed
during which Australian Mining Criminals, Political Criminals and the rest
of that obvious Criminal Country, have behave indeed in the most callous
fashion, It is appropriate that according to my standards, NOTHING should
be done which could benefit such people ... and handing out my discoveries
to the rest of Humanity would in no time reach that dastarly country indeed
.....
It would please to the most to know that the dastarly bastards' relatives or
descent of those Australian Criminal Mining, Political, Administration,
who have done their utmost to destroy my life and indeed push me to the
gutter, should be at that very time suffering hell, while the immediate
cures I have discovered through a very parculiar way at looking at things,
could save in no time those men, women or children .... relatives or related
to Sir Corrupt Court, Court Junior, Mansaros, Burke, Parker, Dowding,
Lawrence, Gallop, Howard, Frazer, Hawke ... and Leroy, Malozemoff, Murdy,
Etheridge, Palmer or to that rabble working in the Great Sandy Desert at
the present time for that Mining Manure ....from whom I never got a single
word of thanks ever in 35 years time !!!

YEP, the wheel of fate has turned, and may be in 35 years time, if an
immediate solution to that situation could be found now, I would hand out
those other discoveries ... of great interest indeed !
..... but don't worry Mr Doug Wheller, those beats of prey and hard-as-nail
Australian Criminals will prefer to see their dear ones dying under their
very eyes .... rather than letting go of their bounty !
I know that shit well indeed !!!

Further, I am sure the Olde 17th century Scottish Druid, who composed that
prayer down below, would certainly approve my most honourable stand !

Lowest price for that model is $299. I think RRP is about $375.

LAST DAY BEFORE CRITICAL WINDOW FOR THE GREAT SYDNEY QUAKE

& GOOD LUCK TO THE BEST OF YOURS WHO HAVE TAKEN MY WARNING SERIOUSLY.


Sir Jean-Paul Turcaud
True Geologist
Founder of the True Geology

Dear Jean-Paul Turcaud,

I have been trying call you for several days to keep you up to date
regarding our partnership as per our agreement at our last meeting.

As the partnership contract was not ratified, I hereby inform you that I
will not be proceeding with the said partnership contract. In other words my
business with you 'Sir' has ended. Formal correspondence will be forwarded
to you via courier.

On the upside, I have just received returned signed contracts regarding some
business deals I have put together - in my sole name.

I have in my sole name signed contracts for THE GREAT SYDNEY QUAKE:

- a $US250 million dollar movie contract
- an $US100 million contract for international televised rights
- a $US10 million contract for publishing rights in the form of a 2 series
book release
- an $US2 million contract for all publishing rights for New Idea and
Women's Weekly (with pics)

Sorry you will not be sharing in the huge amount of money I have
received from the above business deals.

Sounds like Telfer all over again for you old son.

Bad luck 'mate' and better luck next time.

BTW - thanks for the info re the quake

Yours Sincerely

Your Friend

Umm.. I don't know guys..

From my experience, xcopy only worked up until the end of WFW (3.11). When
we went to 95 and beyond, I found that this didn't work as the long file
names were not properly transferred (unless you used the lfnback util on
the
cd) AND any security info (esp. WinNt) was also missed..

Get your hands onto the following as I have found them to work.

Ghost (even the pre-norton version works)
Powerquest Drive Copy (slow and cumbersome but has a few extra features)
Laplink 5.0 (Seriously, it works! Even Novell Volumes!)

And a better (free) solution..
If you are dealing with Win2000, you can install the second drive as a
slave
and then use disk administrator (courtesy MS) to mirror the drive!. Leave
it
run for an hour or so (until disk activity slows down) and there you have
it.. A second hard drive ready to drop into another PC. You may have to
break the mirror first - maybe..

I had a Centrx 51cm television its picture tube blew under one year, so
they replaced it with a brand new one. Great, but now have just realised
that it hasn't got an headphone jack socket at the front like the old
one. Went to The Goode Guys and they said no Centrex tv's had headphone
sockets, this puzzled me so I checked the original book and it has a
picture of the socket. Can anyone shed anymore light on this am I just
seeing things and going senile or what.



Do you actually use the headphone socket? If so, maybe you could look
at one
of the wireless sender units, which would be more portable for you
anyway.

I like their methodology though - when faced with the facts, ignore them,
deny them, question you....

Cheers.

Yes we do use the headphone socket, as a member of the family is quite
deaf and needs them so as not to have the tv blaring at all hours of the
day and night.

There are products for the hearing-impaired which do exactly this
function, using either the headphone socket or AV outputs (audio only,
of course!) to send tot he listener via FM radio, with a nice little
receiver and headphones for them to wear. Much more convenient than a
trailing lead. My MIL uses one and is quite happy with it (she's made a
habit lately of pretending to be listening to a conversation while
actually listening to one of the music stations off the Sky box!).

high impedance, and have to be the easiest headphones
to drive of the over a dozen that I have.

The 580 is so easy to drive I can't see that as a

You're totally at odds with received wisdom here, Arnie.
Check the search engines on any headphone site (say,
Head-Fi) and you'll find the 580 is one of those phones
considered to definitely need a dedicated HP amp, the 595
not.

Head Fi is a forum, IOW its the blind leading the blind.

And this accords with my own experience. Where I
would have had the volume at 10.30 with the 580, I rarely
have it beyond 9.15 with the 595. Or perhaps you have a
different way of measuring sensitivity?

Asa long as the phones are more than loud enough with the volume knob CCW of
clipping, why should anybody care?

I'd like to detect whether a line has 12V on it or not and read that into
my micro. The 12V will be quite dirty (from a car). I was thinking of just
using a transisitor, feeding the 12V into the base (via a resisitor) and
using the collector to gnd the micro pin. Will this be enough isolation or
should I use an opto isolator?

Thanks,

that'd work, getting it to treat 8V as "not 12V" could be tricky,
if that's not an issue that's probably the easiest way to isolate
a single input.

That's fine, I just need to detect if the ignition is on or off. If it's 6V
or above then it can be considered on, if it's below that my boards not
going to run anyway

Just to be clear, you think it will provide enough isolation using a
transisitor? And just using a resistor from the ignition to the transistor
would be ok?

Thanks for the reply,

The 595 is much easier to drive, and that's the old

You seem to have an odd idea of what constitutes easy to
drive, Paul. Usually high impedances are easier to drive
than low impedances, all other things being equal.

Which they never are unfortunately.

Yes, there are some high impedance headphones that are tough to drive
because they need so much voltage.

In fact with portable equipment the maximum output
voltage levels are quite often too low to properly drive
high impedance phones IME.

Agreed. Too much of this stuff runs off of just 1.5 volts. 3 volts is
better, and 5 volts covers a lot of territory.

Not that I am unhappy at all with my Senn 580's. I have
other phones more suitable for portable use, and others
still for live monitoring etc.

I use IEMs for portable use, and less costly stuff that I sacrifice at the
altar of live sound.
