SUCCESS.
It feels good!
Let me make a note: I was originally having problems turning my solenoid valve off because I had it in the 0 slot labeled master. I figured there was only going to be one solenoid attached to the system to start so I might as well call it master. Each time I went to create a simple 3 minute irrigation run in google calendar labeled ‘master’ it would automatically just kick on as soon as I started running the script. I thought this was weird, especially when it didn’t shut off.
After that, I tried using some common sense and realized I would just try plugging it into slot 1 titled ‘greenhouse 11’. I ran the script, it didn’t turn on before it was supposed to. The system is working flawlessly. The real test is going to be when I finally get this sucker hooked up to the tomato greenhouse at school. I can tell you THE WORST part of this project was not the soldering, editing programs, etc. The worst part was running around trying to find adaptors for a 3/4 inch hose bib to a 1″ solenoid valve which is barbed on one end, BACK to a 3/4″ pipe size that my dose-a-tron fertilizer injector is sized at. Boy. What a pain.
THANKS RAY! You are gonna really make small scale greenhouse growers VERY COMPETITIVE with large business and we thank you for that. I’ll spread the word to everybody I can about how badass this thing is.
Another side note. I have a VERY talented programmer/web designer working with me on this project. We’re going to try and incorporate open sprinkler into a sensor network. You will be able to monitor and irrigate your media based on a ‘root zone’ management strategy. This means a moisture sensor will be embedded into your media (I use rockwool). That sensor will transmit wirelessly “hey, moisture content fell below X, irrigate. Kthx.”
I think I overcame my package problem with a gui package installer!
I went to the Debian website and found:
http://wiki.debian.org/Synaptic
Python gdata seems to have been installed properly.
The code is edited in the google calendar script, the google calendar is created. I guess it’s time to try and fire this bad boy up?
Ok guys. More roadblocks for me.
Question 1: How do I tell which Rev I have of Raspberry Pi?
Question 2: Which one of theses wires (if any) are my common wires on my solenoid valve?
Question 3: Everytime I download this gdata python client package it wont unarchive. Arg!
I have limited time to get this dang thing operational today while I have an HDMI cable, mouse, and keyboard on loan from the school. Please please please help me out. I’ve tried to wget, I’ve tried to apt-get install, I’m lost.

I’ve established an internet connection both wireless and wired on my Raspberry Pi. I have noticed though when I plug in or remove the wifi dongle the entire Pi reboots itself. I’m sure this is a power supply issue as I’ve not attached it to the OSPi board yet to run for it’s power.
I ran into a bunch of initial issues which were solved with apt-get install, update, etc. My problem right now is everytime I try to download the gdata python client from the Rasp Pi, it seems to download a corrupted file or a file containing nothing to unzip or archive. I’ve updated xarchiver and unzip, even installed new unarchiver programs. Nothing.
Also, for some reason the only port that works for video is my RCA port. I tried plugging HDMI into it at school with the high def TVs and it just laughed at me. I’m getting closer and closer to getting this irrigation controller running! Please advise some courses of action.
PS: Ray, I should be getting that other board back out to you on Monday after I get paid Sunday. 😛

Thanks for the quick down and dirty with linux!
What is the purpose of SSH and how do I enable it? There’s a million tutorials on the net which means a million ways for me to screw this up being my first time go with Linux.
Also, I’m trying to connect with a wifi dongle to an internet connection here at school. It’s password protected and I’m not quite sure how to get around that business in Linux.
I’ll continue searching the net but if there’s a magical command that makes it all better, I’m all ears.
Regards,
Mark
