So, I've been hesitant to post anything about my own controller project mainly because I don't want to feel pressure to "get it done" or anything like that. Now, however, I'm at a point where I may need a little assistance.
Here's a link to the latest schematic for the project (gif)(It's not neccessarily a big file, but the dimensions of the image are big so i'm posting a link rather than an image):

Everything in the schematic works and has been bread-boarded, although not neccessarily as a complete unit.
Here's where I may need help. Folks may recognize the schematic as being from EagleCAD. I'm not involved professionally in electronics in any way so I don't have access to any higher-end CAD software. Does anyone have a licensed version of EagleCAD or some other CAD software, and would be willing to board this schematic when I'm done? There's no way I can get it to fit under the free version of EagleCAD (board size restriction).
The second part where I need some assistance is in my ph interface. I really don't have any electronics background and I'm struggling to get a working interface. If anyone would care to lend a hand, I'd greatly appreciate it. Also, not to be picky, but if there's any way to get it to run from a single +12V or +5V supply it would be great.
Thanks and Regards,
jca
