Arduino based tank controller
G'day all,
So any other canreef'ers spending too much time reading tech jargon of late? I find myself heading down the road into insanity - building a DIY reef controller... Picked up my freeduino SB today (just finished soldering it together - 20 minute project) along with the little bits & pieces to assemble the pH probe reader (less the probe) gotta order up my DS18B20's for temperature readings as active and MRO didn't have anything comparable... In the process of figuring out my high voltage controls - how many plugs I want to directly control - pretty much decided today I'll just build the power center, rather than pay for an american DJ power center to hack... Links for those who haven't heard of these projects: http://reefprojects.com/wiki/Main_Page (wiki sucks but search finds tons of info) http://delicathdesigns.com/LED/ http://richardorme1979.googlepages.com/home Andy

I'm also in the process of building my own controller using the Arduino 328. Purchased it a couple weeks back and just getting familiar with the coding. Thanks for the links. I'll just take advantage of what others have written and change to my liking and re-post for others. Which Arduino are you using for your aquarium controller ??

freeduino sb is what i chose to go with - largely because we've got a local supplier here in calgary
 http://www.hvwtech.com/products_view.asp?ProductID=682 (turns out they have the ds18b20's too - thus i can get some progress this weekend) was seriously thinking about the illuminato or the mega - but a bunch of reading last night made me realize the additional expense is completely unneeded, as there's an I2C port expander available to us... so those extra io's aren't a problem.

Grabbed the DS18B20's for temperature readings (looks like a transistor, i'm going to mount them into an aluminum probe scenario - then encase in epoxy for reef-safety...
Also grabbed a pair of photoelectric resistors - basically to confirm the lights are in fact on... how i'm going to tie those in... Not so sure Looks like I might need a 3rd shield with just an i2c port expander on it - as I'm going to run out of analog inputs quick at this rate...Highly recomend HVW, these guys are great to deal with - extremely helpful thus far. Hopefully I'll have the temp & pH circuits sorted this weekend. Overall plan, is to connect the arduino to a wifi router running dd-wrt (fonera 2100 in my case) use it for the logging & give myself a web based front end similar to the wrrc project from reef central. Not a big fan of the LCD's at the tank - easier to just log into a nice webpage and see the graphs as to how/what things are happening than to try to pull that same info from a little lcd...
