For those who are following I just wanted to give a status update. This isn't an easy update for me to write simply because I've had to make some very hard choices in the last few days. Most of them are due to financials being strung a little bit too tight and the return simply isn't coming back on time and money.
First, the good news. The Arduarium Controller is fully designed and ready to go. Still waiting on some backordered Arduino Headers, but they are fully assembled and ready to rock. The MacroDuino code that's been written to run the controller is pretty great. There's already been some great feedback about additional features to add. Add to that the fact the my Ethernet shield finally came in that means it's time to take the controller to remote monitoring and controlling.
Now for the bad news. Despite my best efforts to develop an EC circuit that is reliable there's still no luck. The problem lies in the fact that you basically need a scope to set the darn thing up and you can't really leave it in the tank. It always needs re-calibration and simply isn't stable so it is being tabled. If anyone is interested I can post the schematics up.
I will also not be selling any enclosures for the Controller nor will I be making an AC board. It's not all bad though because I am designing an enclosure and you can get it printed up at ponoko. At the moment I simply can't afford to design and print enough volume to be able to sell it at a profit.
As for the AC board, the solution I've come up with is to simply use an PCF8574 breakout hooked up to a relay board. There will be an enclosure designed for that as well.
For those that think the project is dead fear not. I've simply had to make some decisions about what I will support and what I won't be supporting. Few realize how much time and money goes into designing something from the ground up. With the recent Arduarium Board release I had to buy a whole bunch of stock which simply isn't selling as well as I thought it might. It's put me in a position where I have to choose either to shut it down or cut it back to something more manageable.
Before I sign off I want to let everyone know that the Ethernet portion of the code is coming along quite nicely. Expect a web app demo sometime soon.
