hi folks,

i just received a few others items. ORP probe, casing, some butttons, my crystal lcd with serial input, just to name a few.

I want to finish the phase 1 asap, which will be the automated water leveling, reporting/alarming over internet, and basic stats gathering (ph, orp, temp, air moisture, light).

I'm still waiting for my arduino mega (need more input/output!), me w5100 shield (the cheap enc23452345 is a piece of junk!) and my floating sensor. I've met the guy who will install my pool and we agreed on my design (second simili-skimmer in the shed). I will send my plan to some local metal shop to get a few quotes and see how much I'll end up paying. I don't expect to pay more than 200$ for this.

I should be able to work on the final look of my enclosure with all the input/output and post some pics over the week-end. stay tune! sorry if i don't have much right now, we are working on getting what we want regarding the pool itself! (which represent a huge investment).

I've tried using your library with pachube example and it's not working. I'm not reaching the area of the code where I talk to pachube server.

http://arduino.cc/en/Tutorial/PachubeCient

only thing that works is the web server example where I can ping my arduino. that's about it.

hi guys,

just received my 2 adapters for ph and orp. (phidget stuff). Also got what I believe is my ph probe. Yes I'm not sure, i've ordered both and it's not written which one is what!!! smiley

anyway, will do some testing this morning and will keep you posted.

Do you think this component would work to analyze water pressure?

http://au.element14.com/freescale-semiconductor/mpx2053dp/pressure-sensor-uncompensated/dp/1566171

I'm just afraid that if I make a hole in one of the pipe after the filter, the pressure will be different in the "T" section compare to what's being pushed as the pressure wouldn't be as much.

I should have listened during those hydraulic pressure classes!

Hi alavaro,

i'm red of shame, I should have noticed it was complaining about my old ethernet library. I removed thse other libraries and it's seems to be working now. I'm able to ping and get a reply from my module (ye!) but the web server ain't working. I'm guessing it's because i'm using firefox. I'll give the pachube a try later today when I have some time. thanks a lot!!! I'll report any bugs.

I was not talking to anybody, just making a statement. I've received a few bad/defective components in the last few weeks and i'm a bid tired of this. I'm well aware of the counterfeiting stuff as I'm traveling in those regions every once in a while. Sad that you get these when you believe you are ordering the  real deal.

Quick update on this:

we met a few pool vendors and we're about to pull the trigger. I decided to go ahead with my "sump" in the shed. I'll get a local steel fabricator to build it, and the pool installer agreed to help me in my project. I'm not getting a P4 and will only get the chlorinator since I'll be making the controller myself. I'm also gonna get a variable speed pump.

right now i'm struggling with my arduino on a few things. those being: ethernet module (enc28j60) being a real b*tch to work with. I'm gonna have to get a "real" w500 one I believe. I also received my phidget probe adapter and I tested them. They seems to work fine but until I get both my Ph and ORP probe there's no way to tell. I'm also having some difficulties with a relay boards I got which was suppose to turn on/off 110V electricity based on 12V input and 5v signal but I'm not sure why it is not working. I just received a few SSD relays that I'll try right after this post. Last problem in the queue is a set of LM35 I've ordered. out of 5, only 1 "seems" to work "ok". Shitty crap from china. I knew 3$ for 5 sensors out of ebay was too good to be true!!

nothing really relevant to anybody reading this post but just to let you know that i'm moving forward and that you should expect some nice pics of the building. I've started working on the enclosure, my water level code is done, if the SSD relay works tonight I should have the initial release ready to show you.

stay tune.

hi,

just to let you know that I bought a pack of 5 LM35DZ sensors from ebay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140544658004&ssPageName=STRK:MEWNX:IT

and that only 1 is reporting "somehow" a decent temperature. Another one is reporting a temperature 10 degrees under compare to the first one, and the 3 others are simply not reporting anything.

the code i'm using is the one below and it has been proven working fine as per another thread and one of my sensor:

Code:
int sample_count;
float val;
float sample_avg;
float temp;

void setup()
{
  Serial.begin(9600); // start serial communication
  analogReference(INTERNAL);
}

void loop(){

sample_count++;
val = analogRead(1);
sample_avg = sample_avg + (val - sample_avg) / sample_count;

if (sample_count>=4096){
  temp=(1.1 * sample_avg * 100.0) / 1024.0;
  Serial.print(temp,DEC);
  Serial.println("ยบ");
  sample_count=0;
}
}


just so you know, being cheap and getting crap from china out of ebay is not helping your case! I'm learning the hard way.

oups, I only had to add this in the header of your example:

#include <SPI.h>

still doesn't work though. I'm not getting in output in the serial box even when using web server debug example. lights on the nic are blinking up. i removed the link between reset and the gnd as you suggested since it was causing those lights to not blink at all, and the store  where I bought this module finally added some diagram and they are not making this connection either (http://www.geeetech.com/DOCUMENTS/Arduino/arduino%20shield/ENC28J60_Network_Module/ENC28J60.pdf)

i'll keep testing, let me know if you have  an idea why it isn't working. thanks for the good work!

hi,

tried the web server example in your library (after downloading it) and i`m getting this error message about spi library. I tried looking up the spi library on arduino.cc but they are saying it`s already included in the software.  any idea what i`m doing wrong?

thanks

error below:

In file included from C:\Users\mduperre\Desktop\arduino-0022\libraries\Ethernet_old\Client.cpp:1:
C:\Users\mduperre\Desktop\arduino-0022\libraries\Ethernet_old\utility/w5100.h:14:17: error: SPI.h: No such file or directory

As of Arduino 0019, the Ethernet library depends on the SPI library.
You appear to be using it or another library that depends on the SPI library.

hi alvaro,

thanks a lot for this. I will try it out over the week-end and report back here.

stay tune!

thank you

ok, i really tried to find how to connect this cheap module I bought out of chinaland and yet I can't find any details on which pin goes where on the arduino. While i'm a complete rookie on this, i'm sure those of you who builded your own ethernet shield will know what goes where.

pins on the module I can use are:

-vcc
-gnd
-cs
-reset
-si
-sck
-wol
-so
-clkout
-int


I tried looking at the ethernet examples (i.e. web server) but i'm guessing that pins are setup in the ethernet library as I can't find any indication about these.

the picture of what I bought is here:

thanks for the help! If someone can tell me what goes where I'll write a quick how to so dummy like me will have a place to go! thanks!

hey quick question for you. Why do I need the goldline control if I have an arduino??  Why did you interface with yours if you are using an arduino?

I'm probably missing the point.

regarding my water leveler failing, since i'm using this sprinkler solenoid, if we loose electricity while it fills the pool, the water will stop! that's what's cool about it.

Ok so a few things. Those are not pretty, just basic drawing I'm doing to help myself understand where I'm going with this. again, basic!

First diagram is the logical flows for the water level. I want to make sure I cover every states of the software, to prevent any failure. I'm hoping to have more success with the ethernet shield since you pointed out some of them are failing.

http://www.flickr.com/photos/38299034@N06/5998722309/

second picture is something i'm still not sure about. I'd like to come up with some sump tank where I could put all my equipments. If you're familiar with salt water aquarium tank, that's what we use (sump tank) for the monitoring/filtering stuff. This small tank would probably be a cylinder with a radius of 6-8 inches, 2-3 foot tall, and have a pipe (3-4 inches) to connect it to the pool. The pipe would need some angle to prevent water staying in during winter. I would also get some portion of the water output from the pump in the tank to get a fresh read on every probe. The temperature would be higher than the rest of the pool, but that's alright if you know and can take this into consideration.

Dave, I saw on your website that you're logging the water temperature. Which probe do you use? I was planning to use a/some LM35DZ and encapsulate them like this guy did:

talk to you later!

hi,

draythomp I wish you were leaving next to my house so I can pick your brain!!!

I got the following to monitor the ph:

adapter to read the probe:
http://www.phidgets.com/products.php?product_id=1130

cheapest probe I could find.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120636420084

I'm working on a custom "skimmer" that I'll use to install all my probes (ph, thermometer, water level, water input...). I'll install the skimmer in the shed and have some pipe in between. I need to draw a plan for the person who'll make it (made of inox) so I'll post it here when done.

I have a few things I need to post here which i'm hoping to do by Tuesday as i'm still in vacation. this includes a call flows for the water leveler, the preliminary code for my arduino and the initial plan for the skimmer, pool and kids fountain.

I know this projects sounds a lot, but considering the amount of money i'm about to spend I'm confident i'll get far enough to at least get a success/failure and not just an unfinished project.

Draythomp, question for you. Which pump brand/model have you bought? Do you control the speed of it with your arduino? Do you have some pictures of your finish project? How do you control the variable speed pump?

markB I don't think this stepper motor would be strong enough to turn a ball valve. If so PLEASE LET US KNOW!! This would be a great and cheap mecanism.

I'm going to use this for the kids fountain and the water leveler input: http://www.orbitonline.com/products/Valves/02/16/01/218/

this us not good enough for the backwash but should be fine for my current usage. I will have to use those actuator later on though.

any of you were able to interface with the chorinator??

thank you guys!

i'll keep you guys posted!
