Hi
I am looking at interfacing environmental parameter monitors (temp
humidity light pH etc. to an old computer. I have been looking at buying 7
old sound cards and using the mic input to do the A/D conversion (have no
idea what software to use (any ideas)). Has anyone else built there own
environment monitoring system. Does any body have any logging software that
is flexible on input source. If anybody has a commercial system that can
interface with 16 or more sensors could they tell me if they use 1 or more
A/D card in the PC or does it have out stations that log and convert it to
data. Any inf./ ideas would be greatly appreciated.
Thankyou everybody for your posts I love the links, the thoughts and the
general spirit of things. Ted I must say a special Thankyou very much for
the time, effort and content of your posts you have shown me the doorway
to so much info that interests me. Finally I must apologise for my lack of
input to the list I am poor at non face to face communications and so I
spend absolutely ages writing a simple E-mail. I just don't have this time
at the moment but in the future I hope to show you all what I've been
doing. (if it works)
Highest Regards
Mark

Hi Arlos
The alternative is to move to Africa, set up your Aquaponics venture based
on a currency that decreases by 30% per annum relative to the US $, where
you can export to the US & Europe at highly competitive rates, whilst still
enjoying 1st world living conditions. Go Africa go.
In all seriousness though, the cause is at least partially related to your
strong currency which enables imports to be made cheaply. We export our koi
to Europe and benefit from this currency imbalance. If you cannot get into
importing from the US, perhaps you should consider investing/moving to a
cheaper locality to export to the US? Alternatively, establish a chain
based on production in the 3rd world and importation into the US.
Leslie
*************
I had a rather forbidding conversation today with a flower grower
(greenhouse/ cutflower grower). He said unless he can find a profitable
venue as he said Carnations coming from Columbia and New Zealand are forcing
him to halt production. he stopped using any heat in the green house this
past spring to help cut costs and still cannot compete. this is a company
that has been in business for three generations. I asked him exactly what it
was that he saw the area he could not compete and that is labor. He pays
between $7-8 per hour and still with flowers flown fresh from New Zealand he
still cannot not compete? How does this affect any operation here? When I
can buy Chilean Sea Bass ( overfished and unmanaged) cheaper than I can buy
Calif farm raised Tilapia, thats sends a strong message to us attempting to
make a go of Aquaponics. Do we apply more technology, scream for tariffs,
grovel for subsities? Lets get some thoughts on this. this is not just a US
problem, we've forced the rest of the world to eat McDonalds long enough.

I have a lot on my heart/mind of late. I apologize for my somewhat
lengthy discourse. Bear with me.
Mike
Arlos, this is again (in my mind,) related to what you believe is gonna
happen in the world in the next few years. I believe we are building a
fallacy of thinking we can rule the world/world markets from one source,
and lets face it, thats where we are headed. GLOBALIZATION. For many of
us, (depending on your belief again,) it will for some of us mean
returning to the land and a simpler life as a means of waiting out this
time.
Remember, the Romans had times like this too, where the masses were
brought together from different culturesnad merged, and it was in times
like this that they created the bloody goggle box of the arena, to keep
the masses entertained, so as to keep the crime and crowds controlled.
For all of what people here are saying, (and I WAS the greatest
UN-beleiever of them all
) Naaaaaah Mike, dont think that way
I HAVE to!
Recently I opened an European electronics catalog, and they were
offering the CE (Communite Europeane) stickers, for sale for folks to
retrofit their electronic equipment, and Im sorry to say, for all of
those who say otherwise.
my Good Book as Brent says, foretells me this
.in the book of
Revelation 13. verses 16-17, that a coming "power" in the world will
force everyone to take this mark or " no one will be able to to buy and
sell (or trade), except the ones who have the mark (ideology/state of
mind), either the name of the Beast, or the number of his name
." Some
see this as a physical mark but even this may be a trick, it is to me
just accepting those who THINK in their minds (forehead) and take the
mark on their right hands, (their symbol of work/deeds/action) that this
"system" is the ONLY way to go.
Read what this catalog (Conrad) says about the CE mark/sticker
For
all of you who need to get the mark for your devices, "This mark is
since the pronouncment of the EMV Law (1996) obligatory and binding, no
devices can be bought sold or traded without this mark
."
Makes me wonder
. coincidence you say? I smile
:> Arlos, see the
world is not building a literal tower of BABEL, but we are still hooked
on the idea that we can be near or surpass the need for God. We are
buidling a one world market, and one world!! Note how God frustrated
that plan THEN!!. He created DIVERSITY. It is said he confused languages
athat point so that man would go apart each to his own place
. Now we
are running towards accepting EVERYONE and EVERYTHING regardless of a
lot, and funny enough, to Leslie and others,(:>) we are running to to
EVEN ONE WORLD language "english". We are now seeing things like
"english lite" (Patois/creole/Ebonics" ) and the same was passed last
year in some parts of Germany
. to read it sounds like a "bad hair
day"
. like literally writing POORLY, in the name of accepting
SUBSTANDARDS so that EVERYONE in the unnaturally created "crowd" feels
comfortable.
It didnt work then and it wont work now
what we are doing Arlos is
building a ONE world MARKET, and if I can say get coffeeboys (or
manipulate!! ) to get his coffee cheaper, I can manipulate his market to
wipe out another country who is resisting's changes' HERITAGE blow for
blow. Sure it takes money and strategy, but there are those who have
both. The idea is to remove national pride and sense of "home"
(Heimatsgefuhl). I could go on and on
. Switzerland as an icon of
neutrality is now so BADGERED even that island will one day fall to the
power of the one world's market
. with all their money they are not
spared, how much more POOR countries????? I giggle here because my wife
just walks in with an article for me to read, in which in bold letters
it say "Switzerland to join UN by 2003!!"
Yet in the first few lines it ASKS the question whether Switzerland
should join or not
.is this SUBLIMAL or WHAt??
"
.the Federal Council (Government) has emphasised its intention to
do its UTMOST to promote membership, on which voters will be asked to
vote in 2002." (end of quote.) How can it be that they KNOW the outcome
ALREADY? Sounds fishy to me
. no pun intended
. :>
Christians will resist this ideology, and like before, in the Roman
Empire, and the Holocaust, attempts will be made to "round us up" and
"feed us to the lions". But the surprise will come, in the form of the
return of the King above all Kings, Lord over all Lords, known as Yeshua
Ha'Maschiach, (Jesus, the Messiah). What a surprise!
For all who want to flame me or write me offlist to blast me
. I openly
ask you this
can you RISK me being right??
You dont need to be afraid. God loved us all that he provided us an
alternative. It is to take on his mind, his concepts, his solutions in
our lives, and it brings a peace that in my life that has passed
understanding the depths of it. That can mean being persecuted sometimes
too. I am willing to go there. In this light I will take your flames
with a smile. I was like many of you doubting
. but now I have peace. I
watch the news and yes I sigh, but at least now it more of a knowing
sigh than a pained sigh. I watch the news to see how everything is
falling in place.
Through a few shadow groups, the master plan is all falling in place.hence my speculative post "Aquaponics for beliefs sake
." A sedgeway of
getting folks onto this mass system of control of ALL trade, is to get
folks nearer to cities and away from their own lands, and onto some form
of computerized data control system. Ever ask yourself how long it will
be before someone suggest the use of just one card for all transactions?
Gas, utilities, birth papers, everything in a single chip? Could we
place this in a physical sense in your body, so that we can track you?
Imagine going to the supermarket and swiping your hand over the scanner
and walking out with the goods
. the bills is already taken from your
account in a remote tranaction
. going through a tollgate and everyone
just reaching out their hands
. swipe and away we go?? Is this
impossible?? And when you see it happening will you still be flaming me?
Just speculatively, since some cant see it
what if some of these
groups that profess love of environment , or peace or whatever
.REAL
agenda is to destroy family? to herd folks away from family fostering
farms and bring them into cities? What if? What if folks
what if Im
NOT a tiny little "silly" voice in the wind?? As Arlos points out there
are a lot of groups out there AGAINST family, posing as folks with
"special" needs.
Sad to say Arlos, for me, I believe the Good Book
. and it predicts
that the majority of us will allow this lie of the need of us to conform
and be TOLERANT, be propogated. Things Will happen just as da Good Book
say
:> Arlos, for you as a friend, I cant tell you of course how to
live your life. I can however wish for you to see the GREAT connection,
the links, the PAIN all of us GLOBALLY are feeling. The Bible calls it
the BIRTH PAIN of distress
in other words, I wish for you as your
friend and for everyone thinking about Aquaponics, to think not too far
and be INITIALLY worried about making millions, personally my advise
would be the same as Ted and Adrianna told me years ago
. do it FIRST
for a hobby
. learn the ropes and then make a judgement. During that
time
learn if you could support your family with what you are
doing
and I dont mean money wise, I mean actually LIVE off it.!! If
you for some reason are later refused the right to trade you effectually
STARVE, if you dont have the necessary tools to live. But it need not be
so. I wish for all my aquaponic friends to be AWARE what we are seeing
hereis JUST THE BEGINNING!!
My word the Good Book even tells me, in Revelation 18. verses 15-19,
that those having dealings with fish, and making their living from the
sea, and ALL having ships at sea, will be affected by the One World City
which is going to fall, (the collapse and judgement of which is
described in the preceding verses.) That to speculating in marine
fishing ventures!!??
.lol :>
There is a FABULOUS example being aired by PBS channel on Jamaica, how
even us in the islands are being "corraled" in, and lassoed by various
trade "agreements" (Control of trade
) effectually starving us if we
dont comply to buy TRASH in some instances
. (sound familiar?) Man,
even the other day I unearthed a scam where we an order of fittings was
sent here and sold as GOOD, when I did some research they really were
"OPTICAL SECONDS" with an increased risk of bursting as I found out!!
(You and I will talk more on that offlist
)
It is BRILLIANTLY filmed IMHO, showing stroke for stroke, how bauxite,
bananas, milk, beef, vegetables, clothes trade, EVERYTHING is/was slowly
taken from us. The great farmers in St Elizabeth who even the Israelis
had to come study as they grew using little water and grass mulch, even
they have mostly gone to get their truck licenses, "veggie-cowboys", and
now by 12 noon they have hauled "their" "produce" from the wharves to
the farm and have already sold their containers FULL of produce from the
States by then! In the interludes the producer shows SARCASTICALLY silly
scenes of tourists drinking themselves silly, watching crab races, or
some other degrading and despicable behaviour.
It is so bad now if you really dont love what you do, for you it is
almost "cheaper" to sit quietly at home!! It is cheaper! After paying
fuel and all and bills, paying North American fuel prices, sometimes
takehome is just about breaking even for the masses. This is just where
the "powers" want us
back at home bored
. willing to take any "arena"
arrangement, as long as its better than our "percieved" folly
Let the test question be, is the idea to control trade and offer some
elite, "Im better than you" solution? Think ISO 900# certification. Good
idea, I worked doing technical manuals for firms to be certified in
Europe but I saw through it in the end
. moneymaking to say the least
Its called tightening the noose through an intricate web of trade
agreements and laws, that defy sane LOGIC
. slowly FORCING us all to
comply, removing heritage and traditions, setting us for a guy who will
say he has the answer to all of it. A lot of us might fall for it.
There are clear signs happening friends that this is all falling in
place.
Im not a pessimist, nor a biblethumper, neither ultra-orthdox nor a
radical. I m just willing to offer my opinion t wider scrutiny, in the
hope that someone might think on what I say.
In light of Aquaponics, think that the threat may not be that your
neighbour doesnt have what you have, but lets say soon someone will jump
say on the net and find he can get the aqua-organo-ponic veggies you
offer for a whad less, and then? As Arlos says the threat is not from
your geographical neighbour but the threat lies thousands of miles away,
and it needs to be taken into mind when you guys do your MATH and
breakevens and Business plans!! Those of you on the Tilapia list are
seeing the posts in recent days of Tilapia flooding the States from
Latin America
I could go on
.and on
. sigh
I guess in this light, on a much
lighter note, those who can adjust, by finding out how to make their
fixed overheads, feeds, recycling water, and in effect their own zero
discharge systems, are those who will be able to shave substantial
amounts off the prices of our products. Arlos, when all is said and
done, the powers that be can still give you a subsidy, so that your
product comes out cheaper, but they would have done it with the "bigger
picture motive" of forcing another indigenous market player out of
business, and keeping the balls in your court. They will milk that till
they can with a FALL swoop mop over the market floor with blankets
imports from somewhere else, leave you in the cold till you are
desperate enough again, and on and on it goes
Zero discharge/nearest-to-zero-input-systems, are in my humble opinion
the ones which will come out on top.
Hungry people do anything for a dollar.
Well almost anything

Subject: Water level sensor
From: Ian Franzmann
Date: Wed, 29 Aug 2001 21:47:32 +1000
Hi Arlos, Barry & Arlus
I hope the following can be understood without a diagram.
Arlus said
>Sounds like a simple curve with no inflection points. I might be able to
>help you with the formula, I can certainly code the VB. Post the
>details. I am sure others besides myself are also curious about your
>sensor.
I have Automated my Aquaponics system eg. use an old PC & WinXX to monitor
pH, EC, Temp, Light, tank water level, Etc. And have come unstuck with some
circle motion/geometry formula, some one I hope on the list may be able to
help.
The Situation:
Tank Water position sensor. The simplest & cheapest for me is a plastic
float on a pivoted arm moving a linear slider potentiometer. Giving a
variable voltage proportional to and converted to millimeters as a returned
value from the Voltage port on a DrDAQ parallel port data logger & control
unit.
http://www.DrDAQ.com cheap fully functional (no signal conditioning
required) high schools are using them.
The Problem:
I found the Computer returned water level value (from Dr-Daq) is not
linear. due to using a float arm and the linear slider potentiometer.
There are two separate concentric circles one for the slider pot and one
for the float.
Both project onto a chord of each circle.
The slider potentiometer arm is slotted so that it moves the slider with
out bending it.
The vertical slider pot distance is the chord of the inner circle.
The Pot slider moves up & down along a chord of a circle of the slider
potentiometer arm and moves the same angle the float arm scribes.
The vertical diameter of the outer circle is the chord of the float circle.
The float /slider potentiometer arm angle change is not equal for every
unit of water level change.
The Solution needed: I hope I can describe this clearly enough.
Problem is to find the point value on the vertical diameter of the scribed
circle that the float position projects horizontally onto eg. actual water
level. Using the Pot slider value/position.
Simple harmonic motion of a circle math will work, getting the right
formula equation will be fun.
I am using Visual Basic 6 to convert the returned value to an accurate
water level using this circle geometry formula? Is it possible?
Circular motion or SMH?
x =position
A = Radius
x(t) = A cos (Omega t+ phi)
Circle chord math?
The two concentric circle math can be equated by the equal angle of arm
movement.
If any one can help? I would appreciate it.
Reasons for monitoring:
I have realized it may be of value to monitor the tank water level every X
minutes to determine leaks, calculate water loss from
transpiration/evaporation, low water alarm, low water tank fill, volume of
water off tank at any paticular time, how many BTUs heat in volume of water
present eg. energy required for a constant temp, Etc, Etc.
All these values can be viewed on a time graph/charts for Aquaponics system
operation, learning & analysis.
I find this part of construction a lot of fun.
Ian

OK,
I got to understand one thing. Is it a policy of the members of this to do
everything the hard way and as el cheapo as possible or is it allowed to we
to do it right once in a while?
Why on earth would anybody want to jury right a whole bunch of oddball
hardware to monitor a few basic parameters, when a whole array of such
sensors are readily available commercially, are made to high standards and
tolerances and are highly accurate? Sure, you will blow a couple of hundred
bucks more, but you will have a reliable instrument for years and years,
while the jury-rigged alternative may or may not always work, may or may
not be accurate, may or may not need extensive fiddling with it, thus
eating up precious time (and time is money) that could be spent improving
production or performing basic maintenance on equipment thus avoiding
costly service calls from professionals.
Just a thought

Andrei,
You said it all. It would take an individual years and untold $$$ to be
able to come close to what is relatively in expensive. Between Hach, Signet
and a few other companies I can spec, design and install with no worries.

Andrei,
You said it all. It would take an individual years and untold $$$ to be
able to come close to what is relatively in expensive. Between Hach, Signet
and a few other companies I can spec, design and install with no worries.

I do understand it to some degree as I'm one that does this kind of
thing. I will say it's not for everyone, and can very well be more
trouble than it's worth, especially if your not well into electronics.
For me it is a sideline that I like very much. I can make a device
that works "just" the way I want it to, not the way someone else
wanted it to. I also know just what it means when I get a reading of
such and such.
Now I would never for a minute say that someone that has a little
computer and/or electronics knowledge should do this. If writing
computer programs isn't something you do everyday or a Heath Kit is
your idea of electronic experience then by all means you should be a
good commercial system and not regret it. But it's not beyond what
someone can build on there own given the correct knowledge and
experience, just don't expect to do it with what you learned in high
school.

Arlos,
In a previous email you mention "Hach, Signet and a few other companies". I
assume that these companies offer monitoring hardware and you were making
the point that it is better to buy from them than to make your own. For
those of us on this list who are less enlightened in these matters, could
you provide more information on sources of monitoring systems and hardware.
Maybe even list web site addresses if possible.
Thanks,
Gene

Subject: Removing solids from a closed system
From: Mick
Date: Wed, 29 Aug 2001 10:08:53 -0500
I've come up with an idea that seems to be working. Thought I'd share
it with you folks since I've learned so much from all of you.
The thread on vortex filters and the K.I.S.S. principal gave me the idea
to make the flow of the water do the work.
Our plant tray is gravel filled and slightly elevated at one end so that
gravity returns the water to the fish tank. Across the elevated end of
the plant tray is a perforated pipe through which the water is
introduced to the plant tray. There is no piping under the gravel as
gravity does the rest of the work.
In leaving a six inch gap between where the water comes out of the pipe
and where the gravel starts, we've formed a collection pool of water
and solids. I've tried scooping the solids out with a net but that
mostly makes a mess. Fish solids aren't very solid at this point.
The solution has been using small breeding cages. They have a plastic
frame covered with a very fine mesh netting. The ones I have are the
perfect size to fit in the collection pool. By placing a line of these
cages in the collection pool directly in front of the start of the
gravel, the water is forced to flow through the cages before it goes to
the gravel. This removes most of the solids and so far hasn't blocked
water flow to the rest of the plant tray. Every other day, I dump the
cages in a bucket I keep handy and use the solids as fertilizer for my
potted plants.
I'll let you know in a couple of weeks if this has worked out past the
experimental stage as I'm gradually phasing out the bio-filter which has
been removing some of the solids. If the breeding cages can handle all
of the solids from the 850 gal fish tank, then it's a solution requiring
no additional technology/moving parts and very little expense.

Can anyone provide some insight on automated controls ??
Most everything I've seen is 'custom' & pretty expensive
relative to the 'dropping like a Rock' prices of pc's.
I would appreciate learning more about scalable, flexible
controls for the smaller grower / greenhouse.
Thanks list
Dave
Now just a couple weeks away from our

2. barn animals for Co2 and added heat 3. fish for =
nutrients=20
4. plants for O2 animals and food for the family of 4 =
by=20
barn aniamals I mean cow, goats, polutry,
by no elec =
solar=20
heated water I mean a pumped system of pipes that pump water =
to a=20
series of solar =
heaters=20
similar to PV panels that the water heats up then is pumped =
back=20
into the holding tanks=20
for the fish=20
I think this is something that many of us =
would be=20
interested in learning about. I look forward to reading if =
someone=20

Solviva also used a special 3M greenhouse film which is not available
commercially.

the use of Solar (Thermal) is going to be limited to peak efficiency
around 1:30 PM. Considering the short days in Northern climates it may
offer only a slight increase in heat gain

Mark,
If anybody has a commercial system that can

Check these guys out
http://www.rtdusa.com/
Here's the card I have used the AD2110 we did everything differential so
only had 8 inputs
http://www.rtdusa.com/ada1110.htm
It worked great, they have a multiplexer to expand the number of inputs,
but I can't find it on the site. With it we had 23 differential
channels with only one card in the PC.
Good luck. Of course I don't have anything to do with these guys other
than I have used their product. They provided good support
Bill
