Central Coast Field Day-Wyong 1 hour north of Sydney Sunday 19th Feb

Looks like a bumper field day. The biggest list of exhibitors is years.

All the undercover exhibitors area is fully booked with regulars, new
exhibitors and old friends from past field days returning.


Note the new parking and racecourse access arrangments to make entry
quick and easy.

For all the details www.ccarc.org.au/fieldday/

A pity that you can't camp within coo ee of the place the night before.

Like the electronic scales I bought from ebay.

I thought they were really accurate for a while because if one got off and
on a few times the scales still came up with the same mass i.e. 76.8kg
76.8kg 76.8kg etc etc until I discovered it just stored the previous
reading in memory and if the next reading was within 0.5 kg the scales
would simply display the previous reading.
Same with the jaycars scales, the reading would float around but then at the
very last moment always land on the exact same reading. To get an accurate
reading you have to pick something up that weighs over 500grams to reset it.

But the readings looked wrong. So I drank a lot of water, and found
the "% body fat" reading went up, not down!
Is it possible this is a limitation of the methid being used? Maybe the
water needs to be distributed throughout the body?

I ordered a set of those "body fat" weight-scales from Jaycar.
The idea is that by passing a small high-frequency current through
the body, you can measure fat/water proportion, and compensate
for hydration level.
But the readings looked wrong. So I drank a lot of water, and found
the "% body fat" reading went up, not down! More tests confirmed that
the fat reading is based solely on weight, and the age/height/sex data
that you enter. The electric fat reading is faked.

This is the old-model "satrue sbf-2003a". Is the new one any different?
http://www.jaycar.com.au/productView.asp?ID=QM7249

The website is carefully-worded, but the packaging clearly claims that
it electrically measures fat.

I suppose Jaycar will refund it, but this makes me mad. Maybe they
will be shocked at my news, and initiate a product recall. Yeah, pigs
might fly - or am I too cynical? Advice please?

(BTW, it was a dumb impulse buy. I should just measure my waistline.
Am trying to reverse the middle-age spread.)
Fuck man, if you are fat, its going to be pretty visible. You dont
need a toy to tell you. I suggest only a fat fuck will complain. I am
getting kinda fat these days, but i dont need any toy to tell me. Get
a life you dickhead, if you are stupid enough to beleive it then you
deserve to be ripped off.

Yep, just south. You can tell by all the aerials in the car park...
Well maybe not a Mcafe, but maccas, from memory.

Tuggerah area, just south of Wyong, on the corner of the roundabout near The
Westfield Shopping Centre.
 
I have been going to the field day for years its great even when they have a
bad day and its raining,
its always been $10 to get in i guess its to pay for the use of the grounds
parking and maybe Insurance
and electricity and i don't think renting it would be cheap for a whole day.

Actually these scales must be doing something because they don't work if
you've got shoes on.

From the flyer "security personnel will be in attendance".

To control all those wild amateur types....?

Roping off the exhibits before official entry time is no fun, that's
when some of the best deals are done...
So that's why there's so little good stuff left at opening time :))))))))

I thought of that, but we did plenty of other tests. All show perfect
correlation
between mass and %fat reading. But it takes several seconds to "measure"
_after_ the weight is given.
It has plausible deniabilty though. No doubt the execs in Taipei
would blame the engineers in China.

Sure the accurate ones need calibration, and are expensive.
Most people just want bathroom scales that are reasonably
*consistent*, and thats much easier.

So I should have been suspicious of the $50 price tag?
The same day I ordered a DVD-player with MPEG-4 for the
same price, and it works fine. It is much more complex
than a set of scales, and includes components of considerably
higher precision. All from China, of course.
When you can find me a reasonably well machined, accurate cheap
chinese set of load cells please let me know. When you can also find
me some decent load cell amps for the same price please let me know.

The cheapest i ever found when in the market was from korea.

You really have to be kidding me, I thought I'd seen everything there was to
see in a newsgroup. But *you* telling someone else that they chew up
bandwidth with pathetic replies. Surely even you can see the funny side of
that.

You sir, are the moron. Should i choose to read your post or
not, i still am given no choice in downloading it.
Wow, so now I'm guilty of causing your machine to download a few bytes for
the header. You should sue for compensation.

Its a shame science is killing off natural selection,
because you would have been slaughtered 2 minutes out of your mothers
stinky hole.
You really are a fuckwit andy.

I'm not so sure that you've been dudded you know. You paid fifty
dollars, and got fifty dollars worth of equipment. Chances are,
the guys who designed it were given a price tag to work to. Knowing
that one cannot do a *repeatably reliable* measurment for that
amount of money, they wrote in a damper that won't allow it to
feed you readings that vary from day to day by too much more than
an average punter will *actually* vary from day to day.

You'd likely be equally upset if you'd gotten a machine that *did*
do a raw calculation every day, but did so with a tolerance of
+/- 30%. At least this way you're getting some degree of consistency
in the readings, even if it takes several days to average out at
an 'accurate' figure.

I think it is fair to suggest that money buys tolerance. The more
money you spend on an instrument, the more accurate it is likely
to be. It is arguable that by virtue of the 'damper' arrangement,
you got a better instrument than you paid for.

Food for thought, if nothing else.

The thing with this one is that is actively deceptive. And they appear
to know it. Its cheaper to give a few refunds, than to change the labels
and manuals, I guess.
Now that's just out and out cynical. You bought junk from a
business that is widely known for buying up cheap junk and selling
it at entertainment prices for entertainment porpoises. To go all
"I know my rights" up on their corporate arse is just being silly.
You bought a toy: You paid a toy price. You got a toy. Why is it
that you're so surprised that you didn't get a precision instrument?

The biggest cost would be the liability insurance

People forget that when they complain about having to pay and entry fee

Cool. Give your faourite posters the thumbs up and your not so
favourite ones the thumbs down!

Who uses google groups?

(I'll answer that: Noobs who don't understand usenet, and who
think that "The Internet" is "The Web".)
Web based groups (and email) is very handy for those who often use
multiple machines.
I used to use a proper newsreader program and an email client but have
now switched entirely to web based and have never looked back. I can
freely move to any machine and have everything available.
Not as versatile in feature set as dedicated programs, but good enough,
and ohh so handy.

Jaycar are like "The Reject Shop" or "Everything's $2". A
substantial (and growing) portion of their business involves
buying up whatever is (1) vaguely electronics related and (2)
cheap from distress sales, dodgy importers, etc and on selling
it to their retail customers. That portion of the business
has a constantly rotating stock that, once sold, you'll probably
not see again. They've probably got a container load of these
scales to shift, and when they're gone, they're gone. (Of course,
I think the exception to the rule is in the 'Aura Interactor'
audio/physical feedback things. I think they got a whole boat-
load of those, they've been pushing them for years!)


I'm not at all surprised at the poor precision. Its about +/- 400g for
weight. If it came anywhere near that for fat%, I'd be happy. The claim
is 0.5% precision. Readout is to the 1/10%.
500g is standard tolerance for entry level electronic scales
of this type, so that's about right. I think it's gotta be
substantially more difficult to get a repeatable reading on
the skin resistance thing though - there's so much that will
affect that day to day.
