lol... Makes sense to me and should be possible through any protocol really, you could go xbee, or wifi but there are security risks to running wireless. Shouldn't be hard to have multiple 'nodes' either, just change the firmware to a different IP address and if you have a SQL Database...

I'd recommend an ITDB02... It's directly compatible with the UTFT library @ http://www.henningkarlsen.com/electronics/library.php?id=51. I had to do a little hacking to the library to get my SSD1963 up and running, but now that I know how I really do like this screen. I agree with the...

I'm not too sure I'll do PID loops for awhile as I'll do the pH and TDS (Total Dissolved Solids) all manually, but it could be used to keep the pH, TDS, Temp, CO2 and RH all in range. But just getting the timers up and running will be the biggest thing. But for a pro room, you'd have a heater...

RFID card reader and electromagnetic lock. The lock can be installed from the inside and the card could be swiped from the outside and the door would open. Edit: Or hide a switch somewhere Edit2: Try item number: 261071042936 on eBay as well... It has 100lb's of holding force.

Thanks. Yeah, it's coming along nicely. Just a few things need to be done now: +Ethernet ---Remote Control ---Add entry to SQL Database +PID Loops +Timers +Blank Screen Saver But atleast the interface is all setup.

Hey guys... Here's the update of the work I've been doing so far. I'm liking this LCD touchscreen I'm working with, it definitely is making the project a little more professional. Check out the video I made (http://www.youtube.com/watch?v=DdbVDJd1Mcc): First it shows the Light Schedule...

Great job. This is essentially my goal but with simple ebb and flow and nut mix tank with dosage pumps like your using and automatic drain. Keep up the good work, I will pull ininspiration from this for my own project.

Wow, it's been awhile now. But atleast I have some time to work on the project again. I never did get a 64-bit program running for windows and I decided to keep moving forward with arduino development instead of the raspberry pi. Now that I've played with it a bit more it seems more like a...

Wow, coming along nicely... Wish I had mine started, but I have to wait.

Those CO2 sensors are the cheapest I've seen, but any word on how they perform?

LB, you using the Pot as some sort of rotary selector for your interface?

Hey, sorry I haven't been around for awhile... But I got my Raspberry Pi from Element 14.

Hey guys, I'm still here... Been super busy. But I have my Raspberry Pi now and I think I'm going to start developing something for that. I've also since switched to running linux on my desktop box full time now and have just got some eclipse C++ action on the go now that I've been fooling...

Here it is... all done.

No, I wasn't thinking of PWMing directly to the dimmer circuit, but you can match up the PWM signal from your arduino using the signal from a zero cross detector and some how control a relay... or something along those lines. But you can just control the dimmer circuit with a digital...

http://www.aaroncake.net/circuits/dimmer.asp This little circuit would be a step in the right direction. You would just need to interface it with the PWM output from the arduino. This circuit is good up to 350W and most of those inline fans seem to be around 150W.

Bam! I was 215 once @ 6ft and was starting to feel good. But 265 is straight up Jay Cutler, Arnold shit right there.

I'm definitely down for the wiki, as it might grow some public interest and it would be interesting to see some other ways of doing things.

Alpha 15 up - No more Firmata - New Arduino code with custom serial communication (Arduino can be ran independently now) - Cleaned up Export to HTML - Datalog to SQL Server Database - Scrapped graphs in Labs - New History tab allows you to select a date range to view datalog data in graphs...
